Expert Insights

Pro Tips: Strange HVAC Noises

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

1

Listen for Capacitor Failure

Run and start capacitors are among the most common HVAC failures. Symptoms: hard starting, humming without running, or unit not starting at all.

2

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.

3

Verify Thermostat Settings

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