Something Off With the Air or the System?

Details That Save a Second Trip

For a repair, note what the system is doing (blowing warm, short-cycling, tripping a breaker) and roughly how old it is. For an air problem, note when it shows up: a musty smell on marine-layer mornings, haze in the rooms on smoke days, dust back on the vents a week after a filter change. Then tell us where the equipment sits, whether that is a closet furnace in an Ocean Park walk-up, a rooftop unit on a Venice duplex, or an attic air handler North of Montana in Santa Monica. If a building manager or HOA controls roof or garage access, say so up front so the visit is planned around it.
