Air conditioning almost always announces itself before it quits. A room that never cools, a unit that runs all afternoon and never catches up, a smell when it kicks on. Tell us what it's doing and we'll tell you whether it's a part or the end of the road. SwiftPro covers Reston for AC repair, replacement and maintenance, and a person answers the phone.
What you'd notice, and what it usually means
It runs and runs and the house never gets there: Worst in the afternoon. Usually low refrigerant, a coil packed with dust, or a system that was undersized for the house it went into.
Noises that weren't there last summer: A screech on start-up is usually the fan motor. A hard click and then nothing is the capacitor, a cheap part that strands you on the hottest day of the year. Grinding means shut it off and call.
Warm air, or one room that never cools: Air blowing warm points at refrigerant or the outdoor unit. One hot room with everything else fine is usually a duct problem rather than the AC.
A musty smell when it kicks on: Water sitting in the drain pan or on the coil. Worth catching early, because a pan that overflows is how an AC job turns into a ceiling job.
Why it's worth dealing with now
Air conditioning fails in July, not in April: That isn't bad luck, it's load. Everything a system does wrong in spring it does worse under heat. A spring diagnosis is a scheduled visit; the same fault in a heatwave is an emergency call.
A dirty system charges you twice: A clogged coil makes the compressor work harder every hour it runs, so you pay on the power bill and then again when the compressor goes early. The compressor is the expensive part.
Know which conversation you're in before you spend: Past about twelve years, or on a system still running R-22, a repair can cost more than it buys you. We'll say so. You should see that arithmetic before you agree to a part.
