Common HVAC Issues & Troubleshooting Steps

Air Conditioner – No Cooling
If your air conditioner is running but not cooling your home:
- Check the Thermostat – Ensure it's set to "Cool" and the temperature is lower than the room temperature.
- Inspect the Air Filter – A clogged or dirty filter can restrict airflow. Replace it if necessary.
- Check the Circuit Breaker – A tripped breaker may have cut power to the unit. Reset if needed.
- Inspect the Outdoor Unit – Clear any debris or dirt around the unit for proper airflow.
- Check the Refrigerant Levels – If your AC is running but not cooling, you may have a refrigerant leak.
If these steps don’t restore cooling, contact us for service.

Heat Pump – No Heating
If your heat pump isn’t providing warmth:
- Check the Thermostat – Ensure it's set to "Heat" mode and the temperature is higher than the room temperature.
- Inspect the Air Filter – Dirty filters can restrict airflow and reduce efficiency.
- Check the Outdoor Unit – Make sure it’s not covered with snow, leaves, or debris.
- Inspect the Circuit Breaker – If tripped, reset it and see if the heat pump turns on.
- Check for Ice on the Coils – If the outdoor unit is frozen, turn off the system and let it thaw.
If heating is still not restored, schedule a repair with us.
