Expert Insights

Pro Tips: Furnace Not Heating

Pro-level knowledge our network technicians use to diagnose and resolve this problem faster.

1

Never Ignore Refrigerant Loss

Refrigerant should not deplete unless there is a leak. Topping off without locating and sealing the leak is only a temporary and costly fix.

2

Verify Thermostat Settings

Confirm the thermostat is set to the correct mode (heat/cool), the target temperature is appropriate, and the battery is fresh.

3

Inspect Electrical Connections

Corroded or loose wiring causes intermittent failures and is a fire hazard. Always shut off power at the disconnect before any inspection.
