How Brentwood weather works your HVAC system
The lower streets keep some ocean influence while the canyons above turn hot and still, so one city carries two different cooling loads and a single sizing assumption fits neither well. Wind events drive smoke and fine ash down those canyons in fire season, which puts duct tightness and filtration on the list alongside capacity. That is part of how we scope every ductwork services visit here, our starting checklist already accounts for the heat load, the dust the system pulls in, and how long it has to run at Brentwood and the Westside of Los Angeles.
