Heating & Cooling System Not Working?

If your heating or cooling system isn’t working as expected, a few quick checks may help resolve the issue before calling for service.

1. Confirm the system has power Check your electrical panel to ensure all HVAC-related breakers are fully in the “ON” position. Also look for any emergency shutoff switches (often near/on the unit, in the basement, or near stairs) and make sure they haven’t been turned off accidentally.

2. Fully reset the system Try resetting the unit by turning the HVAC breaker off, waiting about 30 seconds, and then turning it back on. This can clear minor system faults or control errors.

3. Check thermostat settings Make sure the thermostat is set to the correct mode (Heat or Cool), the temperature is set appropriately, and the fan is set to “Auto.” If your thermostat uses batteries, replace them if they’re low.

4. Heat pump only blowing cool air? If you have a heat pump and the system is running but only pushing cool air, try switching on the Emergency Heat setting. This bypasses the heat pump and forces auxiliary heat. If emergency heat works, it may indicate a heat pump or outdoor unit issue.

5. Inspect air filters and vents A clogged air filter can restrict airflow and cause the system to shut down or perform poorly. Replace dirty filters and ensure supply and return vents are open and unobstructed.

When to Call for Help

If these steps don’t resolve the issue—or if the system continues to shut off, make unusual noises, or fails to heat or cool properly—please contact your HVAC installer or service contractor directly. They have the tools and expertise needed to safely diagnose and repair the system.

You can find your HVAC contractor contact information on the sticker on the air handler in your basement or log into your Outlook Homes Owner Portal.
