Here are 3 things you should check before calling an HVAC tech:
1. **Thermostat batteries** — dead batteries mimic system failure.
2. **Air filter** — a clogged filter can shut your system down.
3. **Breaker** — HVAC breakers trip more often than people think.
If all three look good and it’s still not working, then it’s time to call a pro.”
