Before You Call: 6 Safe Checks Homeowners Can Do
These are safe, simple checks that solve a lot of “no heat” issues. If anything smells hot, you see damage, or breakers trip—stop and request service.
1) Thermostat settings
Set to HEAT and raise temp 2–3° above room temperature. Replace batteries if needed.
2) Air filter
Replace a dirty filter. Restricted airflow can cause shutdowns, overheating, and short cycling.
3) Furnace/air handler power
Check the switch near the unit and the breaker. If a breaker won’t reset—stop and schedule service.
4) Vents & returns
Make sure supply vents are open and return grilles are not blocked by furniture or rugs.
5) Heat pump mode
If you have a heat pump, confirm it’s in HEAT (not EM HEAT unless needed) and give it time in cold weather.
6) If you smell gas or burning
Shut the system off and call right away. Use Contact.
