Eastside summers used to be easy on air conditioning, but heat waves, like the 2021 heat dome, showed how quickly a broken system becomes a problem. Repair companies get busy when it's hot, so it pays to check before the temperature climbs.
1. Change the filter
A dirty filter restricts airflow, makes the system work harder, and can lead to freeze-ups. Replace it on schedule.
2. Clear the outdoor unit
Turn the system off at the thermostat, then remove leaves, grass clippings, and debris from around the outdoor unit. Keep plants trimmed back a couple of feet so air can move freely. You can gently rinse the fins with a garden hose, without high pressure.
3. Test it early
On a mild day in spring, run the system for 15 to 20 minutes. Air from the vents should be noticeably cooler than the room. If it blows warm, or doesn't start, you've found the problem while repair calls are easy to schedule.
4. Look for warning signs
- Ice on the refrigerant lines or outdoor unit
- Water pooling near the indoor unit, which could point to a clogged condensate drain
- Strange noises, burning smells, or the system turning on and off quickly
- Rooms that never cool evenly
5. Check the thermostat and schedule a tune-up
Confirm your thermostat works and is set to cool. A professional tune-up checks refrigerant levels, electrical connections, and the coil, which are things you can't do yourself. Scheduling it before the first heat wave means you get a convenient appointment instead of waiting in line.
If it fails anyway
Turn the system off, don't keep running a unit that's icing up or making unusual noises, and call for service. In a heat wave, take care of vulnerable family members and pets, stay hydrated, and use fans and shade while you wait.
