1) Thermostat settings
Title: Start with the obvious
Subtitle: It’s more common than you think.
- Make sure it’s set to Heat or Cool (not Off)
- Confirm the set temperature is actually above/below the room temp
- If it uses batteries, try replacing them
2) Breaker or disconnect switch
Title: Power problems happen
Subtitle: Especially after storms or surges.
Check your breaker panel for a tripped breaker. If it trips again, don’t keep flipping it—call for service.
3) Air filter condition
Title: A clogged filter can choke the system
Subtitle: Airflow issues often start here.
If your filter is visibly dirty, replace it and see if performance improves.
4) Vents and airflow
Title: Don’t block your own comfort
Subtitle: Closed vents can create uneven temperatures.
Make sure vents are open and not blocked by rugs, furniture, or curtains.
5) Check for obvious signs
Title: Look and listen
Subtitle: Small clues help you diagnose faster.
Notice any:
- Unusual noises
- Burning smells
- Ice buildup
- Water pooling near the system
If you see ice or smell burning, turn the system off and request service.
6) For cooling: check the outdoor unit
Title: If the outdoor unit isn’t running, cooling won’t happen
Subtitle: A quick visual check can tell you a lot.
If the outdoor unit is silent or clearly not running, that’s useful info for your service request.
7) Don’t wait if comfort is dropping fast
Title: Timing matters
Subtitle: Small issues can turn into bigger ones.
If you’ve tried the basic checks and it’s still not working—or the problem keeps coming back—it’s time to stop guessing and get it handled.
