Heating and cooling, both back on.
A heat pump works year-round, so a failure is felt in any season. We diagnose both modes, the reversing valve, the defrost cycle and the controls, and repair the part that fails.
- Checks: Reversing valve, defrost cycle, refrigerant, controls
- Both modes: Tested in heating and cooling
What it is, and why it matters.
Heat pumps share many parts with air conditioners and add a few of their own: a reversing valve that switches modes, a defrost board and sensors that melt ice from the outdoor coil, and backup heat strips. Problems include a stuck reversing valve, a failed defrost cycle, low refrigerant and backup heat that runs constantly.

Heat Pump Repair: common questions
Why is my heat pump blowing cold air in winter?
It may be in a defrost cycle, which is normal for a few minutes. If it persists, a stuck reversing valve, low refrigerant or a thermostat setting may be the cause.
Why does my backup heat come on so often?
Backup heat should assist on very cold days. If it runs constantly, the heat pump may not be heating properly, or the thermostat may be set to call for it.
