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."

"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."

"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."

"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."

"Back bedrooms were always 4 degrees off the thermostat. After balancing dampers and a return upgrade in the hallway, the spread is under 1.5 degrees. They walked me through every measurement."

"Knocked one star because scheduling slipped a week. The work itself was excellent. Static pressure dropped from 0.91 to 0.58 inches and the new addition finally gets airflow without the hallway thermostat short cycling."

"Hillside bungalow with crushed flex duct in the crawlspace. They photographed every defect, redrew the trunk path, and the air balance report afterward was clean enough to share with the rebate program."

"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."
