What heat pump repair & installation involves
Heat pump work covers both modes. A unit that cools beautifully can still fail in heating if the reversing valve or defrost board is bad, so we test both.
Heat pump service and installation, including cold-climate systems and defrost problems.
Signs you need service
- Never gets the house warm below freezing
- Hissing or bubbling in the lineset
- Auxiliary heat light on all the time
- Unit runs but airflow is weak
- Original community-era equipment reaching end of life
The repair itself
Because heat pumps run year-round, wear items go sooner than on an AC-only system. Most of those parts are stocked and repaired in one visit.
If it's time for new equipment
We'll size for heating, not just cooling, and set up the backup heat and balance point so the system uses the cheapest heat available at any temperature.
Questions from Lafayette 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.
