When to replace
Expensive repairs on an older system, rising power bills, rooms that never cool and a house that feels damp at a cool setting are the usual signs. A system that uses an older, phased-out refrigerant can also be costly to keep running.
Size it from the house
A proper load calculation looks at square footage, windows, shade, insulation and ducts. Homes on wooded ridges and homes on open valley lots can need very different capacity for the same floor area.
Humidity matters
An oversized unit cools quickly and shuts off before it removes enough water. In a humid valley that leaves the house cold and clammy.
Heat pump or furnace
Many local homes use heat pumps, which handle the mild winters well. Others pair an AC with a gas furnace. Your contractor can explain which suits your house and fuel supply.
Variable speed
Two-stage and variable-speed systems run longer at low speed, which removes more moisture and keeps temperatures steadier.
Ducts and crawl spaces
A new system on leaky ducts in a damp crawl space won't perform as it should. Have the ducts and crawl space checked as part of the job.
Permits
A licensed contractor should handle the permit and inspection for your city or county.
Comparing quotes
Look for model numbers, efficiency ratings, duct work and warranty terms in writing. Send a request and an AC company will get in touch.
Plan ahead
Replacing in spring or fall gives you more choice of dates and equipment than a July emergency.
