What heat pump repair & installation involves
A heat pump moves heat instead of making it. That means the reversing valve, defrost control, outdoor coil and charge all matter far more than they do on an air conditioner.
Heat pump service and installation, including cold-climate systems and defrost problems.
What we usually get called for
- Short cycling in mild weather
- Electric bills far higher than expected
- Outdoor fan not running
- System stuck in defrost
- Thermostat and heat pump not communicating properly
The repair itself
We check backup heat staging as part of every heat pump repair — an incorrectly wired strip heater is an expensive thing to leave alone.
When replacement makes sense
If the existing unit can be repaired and run a few more seasons, we'll say so. Replacement is a recommendation, not the default.
Questions from Andover homeowners
- Do heat pumps work in cold weather here?
- Cold-climate models do, well below freezing, with backup heat for the coldest stretches. Older units struggle sooner.
- Why is my outdoor unit icy?
- A little frost is normal and defrost clears it. Ice that stays means a defrost fault, low charge, or airflow trouble.
