Why heating maintenance runs its own way in Brentwood
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. We usually open the visit with burner and heat exchanger inspection, belts, filters, and electrical check, and co detector test, then lock the scope once we've seen the system's condition, what equipment is on the truck, and how the property is laid out.
