Engineering whole home iaq system installation for Santa Monica homes in CEC Climate Zone 6
Coastal comfort work should document corrosion, sound, condensate routing, and whether the home needs zoning or filtration first. That number is the local stress test the whole home iaq system installation scope has to absorb. HOA packet needs, corrosion-resistant placement, quiet outdoor units, and drainage details near shared walls The audit measures static pressure, supply CFM, return free area, and combustion safety on any gas appliance staying in the system; the report names which line item is driving the cost spread on the proposal.
ASHRAE 62.2-2022 mechanical ventilation rate formula: Qfan = 0.03 × Afloor + 7.5 × (Nbr + 1) CFM. An 1,800 sq ft, 3-bedroom Los Angeles home calculates to 0.03×1800 + 7.5×4 = 54 + 30 = 84 CFM continuous outdoor air. Indoor CO2 ventilation proxy ≤700 ppm above outdoor (~1,100 ppm absolute) signals adequate dilution; smart vent controls (Panasonic FV WhisperGreen, Broan AI) modulate to setpoint.
Average summer high near 75°F with winter low around 50°F at an elevation of 105 ft and direct ocean exposure. CEC Climate Zone 6. The cooling design temperature for Manual J calculations runs about 82°F, with typical Manual J load landing in the 400-600 sq ft per ton band. Electric service in Santa Monica is SCE; gas is SoCalGas. Equipment selection should match the rebate path that utility offers when the program applies on the day the contract is signed. The engineer signs the report; the homeowner sees the signature before the equipment order is placed.
