Customer reviews for Breathe LA 365.

"Two other companies quoted a 5-ton heat pump without measuring the ducts. Marcus ran a static pressure test, found a crushed return trunk, and saved us from oversizing. The 3.5-ton install plus duct fix was $4,200 less and actually keeps the back rooms even."

"They thought about salt air corrosion, HOA sound limits, condensate routing on the second story, and the marine layer humidity that was making our bedroom feel sticky. This was design work, not a rushed equipment sale."

"Replaced a 17-year-old AC plus furnace. The Carrier heat pump quote came with the AHRI certificate number, the LADBS permit timeline, and the rebate documentation list. Inspection passed first try."

"Post-rebuild project. They coordinated with our architect on filter access, line set routing inside chase walls, and the Title 24 paperwork. Equipment arrived already commissioned with documented readings."

"Two-zone, multi-system house with conflicting brands. The team labeled each system by room served, replaced the older zone with a Daikin inverter heat pump, and kept the newer Carrier for the rest. No more mystery thermostats."

"South Bay marine air, older ducts, pet allergies in the kids. The plan went heat pump plus duct correction plus filter cabinet, in that order. Comfort is even now and the energy bill dropped about 24% the first month."

"Rossmoyne house, 1948 build, knob-and-tube on the second floor still on the disclosure. Marcus pulled the GWP rebate paperwork before we even signed and sized a 3-ton Mitsubishi MUZ-FH hyper-heat off a Manual J he actually showed me. Static pressure came in at 0.62 in. w.c. before duct work, 0.48 after. Glendale Water and Power rebate hit our account 6 weeks later, exactly as he predicted."

"Fourplex on Western, two units shared one ancient condenser. The team mapped every line set, found one was 47 feet which was over the spec, and rerouted instead of derating the new Bosch IDS 2.0. LADBS permit pulled in 9 days. Tenants barely noticed the changeover."

"Craftsman near York, no existing AC, just a wall furnace from 1962. Marcus walked the attic with a flashlight and a tape measure for 40 minutes before quoting. Ended up with a 2.5-ton Daikin Aurora and a single new return because the existing one was 14x14 feeding a 2,100 sq ft house. Math actually checked out."

"Trousdale lot, HOA sound limits, and a wife who hates seeing equipment from the pool. The engineer found a side yard nook that kept the Carrier Infinity condenser at 56 dB at the property line, well under the 60 dB limit. Condensate routed through a Little Giant VCMA-20ULS pump because gravity drain was not happening on this slab."

"Sand Section, two blocks from the strand, salt air eats equipment. They specced a Mitsubishi MUZ-FS with the coastal coil coating and stainless fasteners. Marcus said the unprotected install down the street probably had 6 to 8 years left, tops. Felt like talking to someone who had actually replaced corroded coils before."

"Bungalow Heaven HPOZ, which I knew would slow things down, but the Pasadena Permit Center took 5 weeks instead of the 3 we were quoted. Once approved, the install went fast and the 3-ton Trane XV19 has been quiet and even. Knock a star off for the timeline communication, not the work."

"Spanish revival on Hill Drive, plaster walls, no way to add returns without tearing up the ceiling. The team designed around it with a high-static Daikin FIT and a single oversized return in the hallway. SEER2 came out at 16.8 on the AHRI certificate. Inspection passed first visit."

"South of the Boulevard, 4,200 sq ft, two zones that never agreed with each other. Marcus zoned it properly with a Carrier Infinity and a Greenspeed variable speed setup, plus a hard start kit on the existing pool pump compressor that was tripping. Bedrooms now hold within a 1.5°F delta of the thermostat."

"Walk Street bungalow, 1,100 sq ft, no attic access from inside. They went mini-split with three Mitsubishi MSZ-GL heads and ran the line sets through a chase the previous owner had used for cable. Clean lines, no exterior conduit visible from the front. June Gloom humidity is finally not turning the bedroom into a cave."

"Stilted house off Mulholland, the old condenser was on a deck that was sagging. Marcus refused to put new equipment back on it without a structural sign-off, which honestly I should have caught. We pulled a separate permit, reinforced the platform, then dropped a 4-ton Bryant Evolution. Refrigerant lockout set at 5°F per his recommendation."

"Magnolia Park, post-war tract home with original 60s ductwork. Static pressure on the old system was 1.1 in. w.c., basically choking it. Replaced with a 3-ton Lennox SL22KLV and rebuilt the supply trunk in R8. Energy bill dropped 31% the first full month compared to last February."

"Silver Lake hills, narrow lot, two retaining walls between the side yard and the equipment location. Crew did great on the install itself, Daikin Aurora 2-ton, but they tracked dirt through the kitchen on day two and the cleanup felt rushed. Marcus made it right with a callback the next morning. Work itself, no complaints."

"Replaced a 19-year-old Goodman that had been limping along since we bought the house. The team ran a full Manual J, Manual D, and Manual S. Came back with a 3.5-ton Carrier Infinity and an actual explanation of why not 4. AHRI number on the proposal, rebate paperwork prefilled."

"Morningside Park, single story, no AC ever installed in the 64 years this house has existed. Marcus designed a 2.5-ton Bosch IDS Premium and added a MERV 13 filter cabinet because of the freeway proximity. Title 24 §150.2(b) compliance was on the proposal, which two other companies had not even mentioned."

"Post-Palisades-Fire, ash everywhere, our old AC was running and pulling soot through the house. The team did a full coil clean on the existing system as a stopgap, then came back two weeks later for the Mitsubishi MUZ-FH install with a sealed return and MERV 16. Honest about what was urgent vs what could wait."

"Norma Triangle condo, HOA gave me 11 pages of rules. Marcus read all of them, then sized a Mitsubishi MSZ-FS multi-zone that fit on the approved equipment pad and stayed under 52 dB at the neighbors line. Approval came back same week. The board chair actually thanked me for the documentation packet."

"California Heights bungalow, 1,400 sq ft, marine air corrosion on the old equipment was visible from the curb. The engineer specced a Daikin FIT with the coastal package and rerouted condensate to a proper drain pan with a float switch instead of the floor drain the previous installer had used. Cleaner install all around."

"Hancock Park duplex, 1928, original gravity furnace in the basement. Permitting was a nightmare on paper but Marcus had clearly done HPOZ work before. Two-zone Carrier Infinity, separate condensers, separate thermostats per unit. Tenant in the upstairs unit said it is the first summer she has not slept with a window fan."

"Tract home off Inglewood Boulevard, 1,650 sq ft, marine layer kept the bedroom muggy even with the old AC running. The team added a dedicated dehumidification mode through a Bryant Evolution variable speed and a fresh duct seal. Bedroom RH dropped from 68% to 51% on a typical morning. Sleeping noticeably better."

"Two-story, 3,400 sq ft, single zone trying to do the work of two. Marcus split it properly, downstairs on a 2.5-ton Lennox SL22KLV, upstairs on a 2-ton, separate Honeywell zoning panel. Refrigerant line sets were rerun through a new chase because the old ones had been kinked behind drywall for years."

"Post-Eaton-Fire, our equipment survived but the ash got into everything. The team cleaned the coil, replaced the filter housing with a sealed MERV 16 setup, and installed a new 3-ton Mitsubishi MUZ-FH because the old condenser had compressor damage from running dirty. Honest assessment that the unit could have been salvaged short-term but not long-term."

"Hillside lot off Lemoyne, the only condenser pad location was 38 feet from the air handler. Marcus calculated line set capacity, added the manufacturer required oil trap, and the system tested clean at commissioning. He showed me the pressure readings on his gauges. First contractor in 4 quotes who explained why distance mattered."

"Kinneloa Mesa adjacent, well water, hard water deposits had killed the previous condensate pump in 3 years. The team installed a Aspen Mini Pump with the auto-flush feature and routed condensate to the laundry standpipe with proper trap. Daikin Aurora 3-ton on the new pad, level within 1/8 inch."

"Veterans Park area, 1,800 sq ft, replaced a wheezy 18 SEER from 2008. The Bosch IDS 2.0 install was clean and the static pressure work was thorough. My only gripe was the initial appointment got bumped twice for emergency calls, which I get, but communication on the reschedule was through text that came late. Once on site, professional all the way."

"Mandeville Canyon, fire zone, equipment had to meet the updated defensible space rules. Marcus knew the ember-resistant venting requirements and specced a Carrier Infinity with the appropriate screening. AHRI certificate, LADBS permit, and the fire department sign-off were all bundled in one PDF I got the day after install."

"Verdugo Woodlands, 1947 ranch, asbestos tape on the old supply plenum. The team brought in an abatement sub for that section before tearing out, refused to disturb it themselves which I appreciated. New plenum, 3-ton Trane XV19, GWP rebate filed for me. Quiet at 54 dB on the patio."

"North of Ventura, 2,800 sq ft, the previous owner had stacked two undersized condensers instead of replacing properly. Marcus consolidated to a single 4-ton Mitsubishi hyper-heat with proper zoning. Removed the dead second unit and patched the slab. House actually balances now, the back office is no longer 8°F warmer than the living room."

"Loft conversion in the Arts District, exposed ductwork was part of the aesthetic, but the previous owner had run flex where rigid should have been. The engineer rebuilt the visible runs in spiral metal, kept the look, and dropped a Daikin FIT condenser on the roof with a vibration isolation pad. Building engineer signed off easily."

"Franklin Hills, 1926 Mediterranean, original radiators we wanted to keep for winter character. The team designed an inverter heat pump as primary with the radiators as supplemental, not the other way around. Mitsubishi MUZ-FH 3-ton, lockout temp at 10°F which we will basically never hit, but the math worked."

"South Redondo, four blocks from the water, salt corrosion city. Specced a Carrier Infinity Coastal with the e-coated coil and stainless cabinet hardware. Marcus walked me through the maintenance schedule for coastal equipment which is more aggressive than inland. Felt like he wanted the unit to actually last 15 years."

"Gated community, the HOA architectural committee wanted equipment hidden from neighboring lots. The engineer drew a screening plan, picked a Lennox SL22KLV that ran at 58 dB, and routed condensate to an existing drainage swale instead of a new tie-in. Approval was a formality. Inspection passed first visit."

"Magnolia Park, replaced a 24-year-old furnace and AC combo with a Bryant Evolution heat pump. The work itself was solid, static pressure came in at 0.51 in. w.c. and the temperature split was textbook. Took a star off because the post-install walkthrough was rushed and I had to email twice for the AHRI documentation. Got it eventually, no issues with the system."

"Ocean Park, 1923 craftsman, no existing ducts at all. Marcus designed a fully ductless Mitsubishi MSZ-FS solution with five heads and one MXZ outdoor. Line set lengths were all under 50 feet so no derating. Permit through Santa Monica Building was clean because he had submitted the load calc up front."

"Lake Encino area, 3,100 sq ft, the existing system was a Frankenstein of three different brands across two decades. The team standardized on Carrier Infinity, ripped out the mismatched zone controls, and installed a single Greenspeed variable system that actually modulates instead of slamming on and off. Comfort difference is real."

"Beachwood Canyon, narrow lot, old condenser was on the roof which had been a leak source for years. Marcus moved the new Daikin Aurora to a side yard pad with proper noise screening, restored the roof flashing, and added a hard start kit on the kitchen subzero compressor that had been sharing the breaker. Better solution than I asked for."

"West Valley summer hits 108°F regularly. The engineer specced a 4-ton Carrier Infinity sized for actual peak load, not nameplate cooling. Refrigerant lockout temp was set with hot weather operation in mind. Compressor has not short-cycled once since install. Energy bill in August was 22% lower than the same month last year."

"Point Dume, salt air plus wildfire smoke, the equipment lifecycle out here is brutal. Marcus specced a Mitsubishi MUZ-FH with coastal coating and added a sealed MERV 16 filter cabinet for smoke events. Condensate pump is a Sauermann SI-30 with a high water alarm wired into the panel because we are not always home."

"Linda Vista, 1939 Spanish, attic was 132°F when they started the install in August. Crew worked early mornings to be safe and finished the air handler swap in two days. Carrier Infinity 3-ton, AFUE backup at 96% on the auxiliary, although we will rarely use it in Pasadena. Pasadena Permit Center inspection signed off same week."

"The Flats, 4,800 sq ft, three existing zones that never worked together. The team did a full system overhaul with two separate Trane XV20i systems, properly sized per Manual J. The old equipment had been oversized by close to 40%, which is why it was short-cycling. House feels different now, not just cooler."

"East of Centinela, 1,500 sq ft, replaced an old gas furnace with a Bosch IDS Premium heat pump. The install was clean and the 17.8 SEER2 has been performing as promised. Minor complaint: they nicked the door frame moving the air handler in and the touch up paint did not quite match. Marcus offered to send a painter, I declined, but the offer was made."

"Old Torrance, 1948 tract, the previous AC had been installed by someone who clearly skipped the static pressure check. Reading on the old system was 1.3 in. w.c., choking the blower. New 3-ton Daikin FIT plus a rebuilt return came in at 0.46. Same house, completely different airflow. Marcus showed me the before and after on his manometer."

"Colfax Meadows, 2,200 sq ft, no aux heat needed in this climate so the engineer specced a straight inverter heat pump without electric strips. Saved on the panel work. Bryant Evolution 3-ton, runs around 48 dB on low which we cannot hear from inside. House holds 72°F in 105°F weather without breaking a sweat."

"Adams Hill, 1924 Spanish, no existing ducts because of the plaster ceilings. Marcus designed a high-velocity Unico system on the inverter heat pump rather than tearing up the ceilings for conventional ducts. Install took 6 days but the house looks untouched and comfort is even across rooms that previously varied by 9°F."

"Oakwood neighborhood, 1,200 sq ft, single story with a finished garage I work from. The team designed a 2-zone Mitsubishi MSZ-GL setup so I can run the office cool without freezing the bedroom. Two outdoor units instead of a multi-zone because the line set runs would have been over spec for a single condenser."

"Garvanza, hilltop lot, the old condenser was visible from three neighbors yards. Marcus picked a Carrier Infinity rated at 51 dB and located it in a screened nook on the downhill side. Neighbor across the canyon actually came over to ask what we did because she could not hear it anymore. Thats a first."

"Belmont Shore, salt air plus tight setbacks, the old condenser was 14 inches from the property line. The engineer relocated to a code compliant spot, replaced the rusted disconnect, and installed a 2.5-ton Daikin Aurora with the marine package. Inspection caught nothing, which after dealing with my last contractor felt like a small miracle."

"Near Centinela Park, 1,300 sq ft, a wall furnace and two window units was the entire HVAC situation. The team designed a 2.5-ton Bosch IDS ducted system with a new return and four supply runs. AHRI certificate matched the proposal. LADWP Consumer Rebate paperwork was filed before they left the driveway."

"Bel-Air on a private road, equipment had to be helicoptered to the nearest staging area, kidding, but it felt like that getting trucks up the driveway. The crew was patient with access logistics and dropped a 5-ton Trane XV20i system over two days. Sound rating at 56 dB even at high stage, neighbors never heard a thing."

"Post-Eaton-Fire ash was still falling when we called for an estimate. Marcus would not commit to install dates until air quality stabilized, which I appreciated more than a quick yes. When we did go, it was a 3-ton Mitsubishi MUZ-FH with a sealed MERV 16 filter cabinet. Honest pacing, honest work."

"Alphabet streets, 2,400 sq ft, replaced a 16-year-old Lennox with a Carrier Infinity heat pump. The technical work was excellent, static pressure dropped from 0.88 to 0.42 in. w.c. after duct fixes. The four-star reason: the original quote did not include the new disconnect that turned out to be required by code. They covered the labor on it but I had to pay materials, around $180, which felt like it should have been caught up front."

"Chandler Estates, 1956 ranch, original ducts were lined with what looked like asbestos paper. Marcus stopped work, brought in testing, came back negative thankfully, but the fact that he stopped is what sold me on the company. 3-ton Daikin FIT, full duct replacement in R8, energy bill cut nearly in half compared to last September."

"Our primary bedroom was 6 degrees warmer than the hallway thermostat at 11 p.m. Breathe LA 365 placed a 9,000 BTU mini split where it would not blow on the bed and tuned the low-speed fan to under 22 dB. We sleep through the night now."

"Condo, HOA approval, roof access, neighbor-sensitive sound. The team handled the packet, picked an outdoor unit rated 51 dBA, and the line route looks intentional rather than tacked on."

"Beach cottage, port-adjacent particulates, undersized central. They added a 12,000 BTU bedroom zone with a corrosion-treated outdoor unit and the MERV 13 strategy for the rest of the house."

"Three-story coastal home, top floor was always 8 degrees warmer. They placed two mini split heads, hid the line set in an existing chase, and the upstairs sleeping rooms are now within a degree of the main floor."

"Valley heat was killing our sleep. Breathe LA 365 sized a 12,000 BTU Mitsubishi MSZ-GL12NA for the primary bedroom and ran a 28 ft line set through the attic. Indoor head sits at 19 dB on low and the room holds within 1°F all night."

"Old craftsman near York, no ducts upstairs. They installed a 9,000 BTU Daikin Aurora head angled away from the bed and a Sauermann SI-1820 condensate pump tucked into the closet. The room is finally usable in August."

"Beachwood Canyon adjacent, narrow side-yard easement, neighbor 7 ft away. The crew picked an outdoor unit rated 49 dBA and oriented it so the discharge faces our own wall. Inspection passed first try and the bedroom runs cold without any whoosh."

"Trousdale property with strict aesthetic rules. They sourced a low-profile Mitsubishi MSZ-FS06NA, hid the 35 ft line set in a stucco chase, and matched the outdoor unit cover to the trim. Whisper quiet at night, under 22 dB on the slowest fan."

"Scheduling slipped a week because of a back-ordered MXZ-3C24NA outdoor, but once parts arrived the install was clean. Two 9,000 BTU heads, line set hidden behind a built-in, and the bedrooms hold steady. Communication during the delay could have been better but the work was good."

"Master bedroom on the west wall baked until 9 p.m. They installed a 12,000 BTU Fujitsu RLF and routed the line set through an existing chase. Indoor head measured 21 dB on the lowest fan setting from my phone. No more sweating to sleep."

"Hillside lot, awkward outdoor placement. The tech mounted a Mitsubishi MUZ-FH unit on a wall bracket above the patio, kept the 22 ft line set clean, and the bedroom head never blows directly on the bed."

"Sunset Park bungalow with two kids in shared room. They sized a 9,000 BTU head, set multi-stage low fan, and the room sits at 68°F all night with no temperature swing. Outdoor unit at 51 dBA so the neighbor never complained."

"Norma Triangle condo, HOA noise rule capped outdoor at 55 dBA. They specced a Daikin RX series at 49 dBA, handled the architectural review packet, and got the line set chased neatly down the back wall. Bedroom finally sleeps at under 25 dB."

"Two-zone install for primary bedroom and nursery. The team picked 6,000 BTU and 9,000 BTU heads off a single MXZ-3C24NA, ran the 40 ft line sets through the soffit, and the rooms stay within 1°F of setpoint overnight."

"Coastal home, salt air concerns. They installed a corrosion-treated Mitsubishi outdoor unit and a 12,000 BTU bedroom head with a Mini Aspen condensate pump. Sleep tolerance is under 1°F and you cannot hear it from across the room."

"Tiny 1920s bedroom, no room for a window unit anymore. They mounted a slim 6,000 BTU Mitsubishi MSZ-FS06NA high on the wall, ran a 18 ft line set, and it disappears acoustically at night."

"Stadium traffic noise meant we kept windows shut. A 12,000 BTU head solved the heat problem and the indoor unit at 22 dB on low is quieter than our old box fan. Tech was clean and pulled permits without me chasing."

"They quoted a Bosch IDS Premium ductless for the bedroom and a separate zone for the office. SEER2 numbers checked out and the install was tidy. Outdoor unit tucked behind the pool equipment, line set 32 ft, and you cannot hear the indoor unit from the bed."

"Verdugo Woodlands, hillside, only one good outdoor location. The crew built a small platform, mounted the unit on isolators, and the neighbor unit-line dB limit was satisfied. Bedroom head holds 70°F overnight with no fan cycling."

"Drywall patch around the line set chase needed a second coat I had to ask for. The HVAC work itself was solid though, 9,000 BTU MSZ-FH09NA, balanced charge, and the bedroom is consistently 68°F at night. Would still recommend, but the work was good despite the cosmetic issue."

"Bungalow Heaven HPOZ, visibility from the street was the big constraint. They placed the outdoor unit behind the detached garage, hid the line set in an existing downspout chase, and the historical review committee approved without revisions. Bedroom is silent on low fan."

"Port-adjacent particulates were rough on the old window unit. They installed a 12,000 BTU Daikin Aurora and recommended MERV 13 filtration on the central system. Air quality and sleep both improved."

"Walk-street property, line set had to cross a shared easement. The team coordinated with the neighbor, ran a 45 ft line set in a low-profile chase, and finished it in matching beige. Bedroom head is whisper quiet, no air blowing on the bed."

"Westside marine layer plus a poorly insulated addition. They sized a 9,000 BTU Mitsubishi for the primary, ran 25 ft of line set, and the room now holds within 1°F overnight. Tech walked me through the remote settings and low-fan modes."

"Whitley Heights home, narrow street, hard equipment access. They hand-carried the outdoor unit up the stairs, mounted it on a side-yard pad, and routed a 38 ft line set without any visible run from the front. Bedroom is now under 25 dB at night."

"Mid-century with no good ductwork option. A 12,000 BTU Carrier Performance ductless went into the primary bedroom, line set through the existing chimney chase, and outdoor unit on a small concrete pad. Sleep quality is night and day."

"Loft conversion, building required low dB compliance for shared walls. They installed a Mitsubishi MSZ-FS06NA at 19 dB on low, used a Mini Aspen condensate pump for the long horizontal run, and the bedroom is now genuinely quiet enough to sleep through."

"Hot upstairs primary, central was undersized. They added an 18,000 BTU bedroom zone, oriented the head away from the bed, and the room cools from 84°F to 70°F in under 20 minutes. Outdoor unit tucked into the side yard at 52 dBA."

"The first scheduled day they had to reschedule for a parts issue, which was annoying. When the install happened it went smoothly, 9,000 BTU MSZ-GL09NA, 22 ft line set, and the bedroom is now usable in summer. The work was good even if logistics were rough."

"Two bedrooms on a single MXZ-3C24NA outdoor. The crew balanced the line lengths, used isolation mounts on the outdoor pad, and both heads run silent. SEER2 efficiency was a clear upgrade from the old window units."

"Valley summer was unbearable in the back bedroom. A 12,000 BTU Hyper-Heat unit with strong COP at -13°F gives us cooling now and heating later. Indoor head is mounted high, no air on the bed, and it holds 68°F all night."

"Ocean Park bungalow, salt air, picky neighbors. Corrosion-treated outdoor unit, 49 dBA, and a clean 30 ft line set chase down the side wall. Bedroom is at 70°F overnight with multi-stage low fan and we never hear it."

"Hillside, oak tree near the only outdoor location. They worked around the root protection zone, mounted on a small wall bracket, and ran the line set 42 ft through the crawlspace. Quiet, clean, and the bedroom holds setpoint within 1°F."

"Post-fire rebuild. They specced a Hyper-Heat MUZ-FH for cold mornings and the COP held strong at lower temps. Bedroom head is 9,000 BTU, line set 26 ft, and the indoor sound floor is barely audible. Honest pricing too."

"Historic district, no exterior alterations visible from the street. They placed the outdoor unit in a service yard, ran a 50 ft line set inside an existing utility chase, and the HPOZ approval was clean. Bedroom is quiet and consistent."

"Beach cottage, neighbor wall 5 ft away. Outdoor unit at 51 dBA on a vibration-damped pad, line set 20 ft, and the bedroom now sits below 25 dB at night. Crew was respectful and cleaned up better than expected."

"Coastal canyon home, hard outdoor placement. They engineered a hillside platform for the MXZ-3C24NA, used corrosion-treated coils, and ran 60 ft of line set through the crawlspace. Two bedroom heads, both whisper quiet, both holding within 1°F overnight. Worth every dollar."

"Hillside bungalow off Sunset. A 9,000 BTU MSZ-FS09NA, 24 ft line set, and a balanced charge that makes the indoor unit functionally silent below 22 dB. Sleep finally fixed."

"South Bay tract home, kids waking up sweating. Single-zone 12,000 BTU bedroom install, 28 ft line set, outdoor at 50 dBA. Multi-stage low fan keeps the temperature dead steady all night."

"They missed a piece of trim work around the indoor head and I had to flag it on the walkthrough. Came back and fixed it within 48 hours. The actual HVAC install was solid, 9,000 BTU MSZ-GL09NA, clean line set, and the bedroom runs quiet. The work was good."

"Discreet install in a primary suite. They picked a Daikin Quaternity for low ambient sound, ran the line set inside the existing wall chase, and matched the head to the wall color. You barely notice it is there."

"Older home, no central HVAC upstairs. The team installed a 12,000 BTU bedroom head and a 6,000 BTU office head off a single outdoor. SEER2 numbers were honest in the proposal and the post-install measurement matched."

"Condensate pump placement was the tricky part. They used a Sauermann SI-1820 in a sound-damped enclosure and you cannot hear the cycling at all. Bedroom head holds 69°F overnight with zero fluctuation."

"Hot west-facing bedroom, central never kept up. A 12,000 BTU Fujitsu RGL with the head mounted high above the closet so no air blows on the bed. Line set 30 ft through the attic, all clean. Sleep quality is genuinely better."

"HOA architectural committee, neighbor noise complaints already on file. They installed an outdoor unit rated 47 dBA, used vibration-isolated mounts, and the line set chase was painted to match the stucco exactly. No complaints since, and the bedroom is silent."

"Marcus measured the return at 0.42 in. w.c. of static and explained why my old 1-inch filter slot was bypassing air around the media. The new 4-inch cabinet finally lets the smoke-season plan we built actually work without starving the blower."

"We called about wildfire smoke after the January fires and ended up fixing a leaky filter cabinet first. AirNow PM2.5 was at 78 outside; our living room PM2.5 dropped from 31 to 6 within an hour of fan mode plus the new MERV 13 setup."

"Older Craftsman with a tiny filter slot in a cramped closet. Marcus designed an offset cabinet that fits the space and added a sealed return transition. Pet hair load on the blower compartment is dramatically lower."

"Postwar home, 14x25 filter slot leaking around the door. Marcus quoted three options: tape and gasket, full cabinet upgrade, or stay with MERV 8 and add a portable. We picked the cabinet and pet dust visibly dropped."

"After the foothill smoke event we wanted real filtration. They tested the blower, sized a deeper cabinet that the fan could push, and showed me the static pressure before and after. No marketing fluff."

"Bungalow Heaven home covered in ash after the Eaton Fire. The crew measured 0.71 in. w.c. static on the old 1-inch slot and explained why air was bypassing the media. New Aprilaire 4400 cabinet brought static back to 0.48 and the visible dust on every surface dropped within a week. Honest scope, no upsell on UV gimmicks."

"Post-Eaton-Fire ash was relentless. They installed a 4-inch Honeywell F200 cabinet and sealed the return transition. Indoor PM2.5 went from 42 to 9 within two hours of running fan mode."

"Kinneloa Mesa, half a mile from the burn scar. The technician walked through static pressure readings before and after, swapped a leaky filter slot for an Aprilaire 2410 cabinet, and gave us a written ash-event maintenance schedule. The 4-inch MERV 13 finally fits without crushing."

"Good install, fair price. Static dropped from 0.68 to 0.51 in. w.c. after the cabinet swap. Took an extra day to source the right transition piece, hence four stars instead of five, but communication was clear the whole time."

"My 1980s system had a panned joist return that was leaking attic air past the filter. They sealed it, added a 4-inch cabinet, and the blower amp draw came down noticeably. PM2.5 in the bedroom holds steady around 4 to 6 now."

"Hillside duplex with a cramped mechanical closet. Honeywell F100 cabinet fit where I assumed nothing would. Less sneezing in the bedroom and the cat hair load on the blower wheel is way down at the six-month check."

"Old furnace, tiny 1-inch slot, total mismatch with a MERV 13. The tech measured 0.82 in. w.c. of static and refused to just slap a thicker filter in. We did the cabinet upgrade properly and the system is quieter and pulls less amperage."

"June Gloom humidity used to make the filter sag in the slot. The new Aprilaire 2410 holds the media flat and the return transition is sealed with mastic, not just tape. Clean install, clean explanation."

"They actually measured static before quoting. 0.74 in. w.c. on a system rated for 0.5 max. The 4-inch cabinet plus a return grille upsize brought it to 0.46. Blower noise in the hallway is noticeably lower."

"Beachwood Canyon adjacent, lots of road dust. The Honeywell F200 cabinet swap and a sealed return panel cut visible dust on the dark wood floors substantially. They also flagged a disconnected flex run I had no idea about."

"Quick, clean, on time. New cabinet, MERV 13 4-inch, static within spec. PM2.5 reading on my consumer monitor dropped from 18 to 5 indoors during a moderate AQI day."

"Coastal house, salt and dust combo. The crew installed an Aprilaire 4400 and resealed the return drop. Six months in, the filter shows even loading across the whole face which tells me the bypass issue is gone."

"Solid work overall. The cabinet sits a bit proud of the closet wall which I expected given the depth, but the framing finish could have been cleaner. Performance is excellent though, static came down from 0.66 to 0.49 in. w.c."

"They measured ACH at roughly 0.4 in the conditioned space and explained why a tighter filter alone would not fix my dust complaint. The cabinet plus duct sealing dropped surface dust noticeably within two weeks."

"Old craftsman with a quirky return path. The technician designed a clean offset cabinet for the closet, sealed two duct connections, and the blower amp draw is noticeably lower. Six-month checkup confirmed even filter loading."

"The nursery walkthrough was calm and practical. They talked about drafts, fan speed, filter fit, humidity, and temperature stability without making any medical promises. The written scope is exactly what we got installed."

"Verdugo smoke days were ruining our toddler's sleep. The plan added a 4-inch MERV 13 cabinet, sealed two return panels, and recommended a portable HEPA for the nursery as backup. Honest about what HVAC alone could not fix."

"Canyon smoke is part of life here. They built a written smoke mode: which fans run, what filter changes when AQI crosses 150, where the portable HEPA goes, and which windows must stay closed. We finally have a plan."

"They built a written plan with three phases: cabinet upgrade now, return sealing next, and a portable HEPA for the bedroom as backup. No magic-box pitches, no UV-C gimmicks. Six months in, our PM2.5 holds in the single digits."

"Verdugo Woodlands smoke days motivated us to do this properly. The plan included a 4-inch MERV 13 cabinet, sealed return drops, and a recommended HEPA CADR for the nursery as a backup. Honest scope, written and stuck to."

"Hancock Park craftsman, original ducts, lots of bypass. The whole-home IAQ scope started with measuring 0.81 in. w.c. of static and walking through what a cabinet plus duct sealing would actually accomplish. They did not promise miracles."

"They mapped airflow room by room, showed me where bypass was happening, and built a smoke-mode plan with specific filter change triggers tied to AirNow AQI. The Aprilaire 4400 plus return sealing keeps our indoor PM2.5 around 5 even on bad days."

"Calm, thorough walkthrough. The written scope covered cabinet, sealing, fan-mode behavior, and a portable HEPA recommendation for the bedroom. We did all of it. PM2.5 dropped from 27 to 8 within an hour of running the new setup."

"Crawlspace was a disaster. Crushed flex, unsealed boots, the works. They photographed everything, rebuilt with R-8 and proper support, and balanced to within ±8%. Master bedroom finally tracks the thermostat."

"Loft conversion with one giant trunk and almost no returns. They added two dedicated returns, balanced the supplies, and got static pressure from 0.97 to 0.55. Every room now hits the design CFM within ±10%."

"Hillside duct chase that had been ignored for decades. They rebuilt it with smoother turns, R-8 flex, and proper support straps. The air balance report came back within ±9% and the rebate program accepted it without revisions."

"Static pressure delta was a nightmare on a 3-ton system. They ran a manometer at multiple points, found a partially collapsed return, and replaced it with hard pipe. TESP went from 0.89 to 0.52, and the system stopped tripping the high-limit on hot afternoons."

"Salt air had eaten through several supply boots. Crew documented every defect, rebuilt with R-8 flex, and brought leakage to 4.2% per the Title 24 test. The hood-and-flow numbers matched the design within ±7%. Excellent crew."

"Estimating phase was slow. But the work was excellent. They photographed every joint, replaced a panned joist return with hard pipe, and the leakage rate dropped to under 5%. House is noticeably more comfortable in the afternoon."

"Mid-century with original ducts in a tight crawlspace. They surveyed with photos, redesigned the supply layout to reduce a long horizontal run, and balanced everything to within ±8%. Static pressure is now 0.6 instead of 0.95. The crew left the crawlspace cleaner than they found it."

"Slab-on-grade home with all ducts in the attic. They added insulation around the plenum, replaced two kinked supply runs, and ran a Duct Blaster test before and after. Leakage went from 17% to 4.5%, and the air balance was within ±10% across every room."

"Hancock Park spec home next door had similar issues, which is why we called. Static pressure was 1.08, return undersized, and the supply trunk had three sharp turns. They redesigned the trunk path, upsized the return to 24x30, and we are now at 0.59 with the bedrooms within 1.5 degrees of the thermostat. Air balance report was thorough."

"Coastal cottage with the supply boots rusted through. They photographed every defect, replaced with R-8 flex, and balanced to ±9%. CFM at the back bedroom went from 48 to 105."

"Returns were way oversized and pulling from the wrong rooms. They resized to proper dimensions, added a transfer grille for a closed-off bedroom, and balanced to ±9%. The hallway thermostat finally reflects what the rest of the house feels like."

"Post-fire returns had ash buildup throughout. They cleaned the plenum, replaced the filter housing, and re-balanced the system to ±10%. Air quality at the registers is noticeably cleaner and the static pressure is back in spec at 0.57."

"Static pressure was 1.0 even and the system was loud. They upsized the return, sealed the cabinet, and replaced one crushed run. Now at 0.58 and noticeably quieter. Air balance came in within ±9%."

"Final inspection of a long project. They redrew the trunk path, replaced 40 feet of flex with R-8, and the air balance report at the end was within ±7% across the whole house. Static pressure dropped from 0.93 to 0.56. Title 24 leakage came in at 3.9%."

"Multi-system home, four thermostats, three different fan profiles. Marcus laid out a sensor-based zoning plan, labeled each system by room served, and the property manager finally has a one-page operating sheet that makes sense."

"Three zone dampers were chattering on every cycle. The fix was a bypass redesign and proper static pressure relief. They explained why a smart thermostat would not have solved it on its own."

"Historic home with strict aesthetic constraints. They specified a discreet zoning panel, room sensors hidden behind millwork, and trained us on the schedule. Bedrooms are 70 at 11 p.m. without overcooling the front rooms."

"Two-story craftsman with the upstairs always 5 degrees warmer. They installed a Honeywell Truezone with two ARD dampers and an Ecobee Premium with a bedroom sensor. Upstairs now within 1.5°F of setpoint and the sleep schedule actually works."

"Slab-on-grade ranch with no attic, so zoning had to live in the closet chase. They specified Zonefirst dampers, a bypass with proper static pressure relief, and a Nest Pro 3rd-gen with two remote sensors. Energy bill dropped roughly 22% after the first full month."

"Three-zone setup that had been chattering for years. The bypass damper was undersized. Marcus walked me through the static pressure relief calculation, swapped in an AprilAire 6504, and paired it with a Daikin One+. Quiet, even, and the occupancy mode is genuinely useful."

"Mid-century duplex unit. They installed a Carrier Cor with two zones and trained us on the schedule. Bedroom holds at 68 from 10 p.m. without freezing the front room."

"Communication on parts ETA was spotty for about a week. But the work was excellent. Honeywell EARD dampers, a Trane XL824, and remote sensors in two bedrooms. The whole house is finally within a degree and a half of setpoint."

"Beachwood Canyon home with three systems and four thermostats. They standardized on Ecobee Premium, mapped each system to the rooms it actually serves, and gave us a single-page operating sheet. The property manager keeps a copy on the fridge."

"Tiny hillside bungalow, two zones max. They picked a Sensi with a single remote sensor for the back bedroom and one Honeywell ARD damper. Simple, clean, and the bedroom is now within a degree of the thermostat at 11 p.m."

"Mandeville Canyon home, three zones with constant short cycling. The end switch wiring on the original install was wrong. They corrected the control logic, paired it with a Bosch BCC100, and the system now stages properly. Bills dropped about 18% month over month."

"Older system, no zoning at all. They added a two-zone Honeywell Truezone with a bypass and an Ecobee Premium. The back bedroom went from 6°F off thermostat to 1.5°F. Sleep schedule is dialed in."

"Coastal home with strict aesthetic rules from the HOA. They hid the room sensors behind built-in shelving, used a discreet zoning panel in the closet, and programmed the schedule around our actual occupancy. Front rooms no longer overcool at night."

"Two-zone setup for a craftsman with HPOZ constraints. They used a low-profile zoning panel, period-appropriate covers for the sensors, and a Nest Pro that the homeowner could actually use. Bedrooms now sit at 70 at 11 p.m. without overcooling."

"Trousdale ranch with four zones and a bypass that was undersized. They redesigned the bypass for proper static pressure relief, added Zonefirst dampers, and integrated a Daikin One+ with multi-room sensors. The whole house is finally even and the energy bill came down about 24%."

"They explained why a smart thermostat alone would not solve our hot upstairs. We did the zoning properly with a Honeywell Truezone, two ARD dampers, and an Ecobee Premium. Bedroom went from 6°F off the thermostat to 1.5°F."

"Simple two-zone setup for a small ranch. Sensi thermostat, one zone damper, clean wiring. Back bedroom is finally usable in the summer."

"Property manager headache: four thermostats across two systems, no labeling. They mapped everything, installed an Ecobee Premium per system with multi-room sensors, and produced a one-page operating sheet. Tenants stopped calling about temperature complaints."

"Tiny duplex unit, one zone needed. They installed a Mysa for the mini-split and walked me through the schedule and occupancy mode. The bedroom is at 70 by the time I get home, no manual fiddling."

"One sensor failed about a month after install and there was a small back-and-forth on the warranty. But the work was excellent overall. Three-zone setup with Honeywell EARDs, a Daikin One+, and clean wiring. Once the sensor was swapped, everything has been rock solid."

"Older two-story, no zoning at all. They added a two-zone Honeywell Truezone with a bypass damper, paired with an Ecobee Premium and a sensor upstairs. Upstairs went from 5°F hot to within 1.5°F of setpoint and the schedule actually holds overnight."

"Three-zone retrofit on a 70s home. They redesigned the bypass for proper static pressure relief, swapped to AprilAire 6504 dampers, and integrated a Trane XL824 with sensors in three rooms. Energy use down about 23% in the first full month."

"Condo with a single zone but a poorly placed thermostat. They added a remote sensor in the bedroom on an Ecobee Premium and programmed a sleep schedule. The bedroom now sits at 68 overnight without freezing the living room."

"Loft with concrete ceilings and limited damper locations. They specified Zonefirst dampers in the only chase that worked and a Bosch BCC100 with a remote sensor. The bedroom area finally holds setpoint instead of drafting cold air all night."

"Two systems, one beach house. They labeled each system by room served, paired both with Ecobee Premiums, and added sensors in the kids' rooms. The kids' rooms are now within 1.5°F of setpoint, which has noticeably improved sleep."

"Four-zone setup that was constantly short cycling. They corrected the end switch wiring, redesigned the bypass, and integrated a Daikin One+ with sensors in every zone. The system now stages properly and the bills dropped about 21%."
