Heat Pump Repair & Installation in Mountain Home, TX

Heat pump supply air is naturally cooler than furnace air, often in the mid-90s rather than 120 degrees, so it can feel cool while working correctly. If it is genuinely not warming the house, suspect a stuck reversing valve, low charge, or a defrost fault.

Light frost and a burst of steam during defrost is normal. A coil buried in solid ice for more than twenty minutes is not, and it usually means a defrost board, sensor, or reversing valve problem.

Auxiliary heat is electric resistance backup, and it costs several times more to run than the heat pump itself. If the aux light stays on constantly in mild weather, the heat pump is not carrying its share and something is wrong.

Yes, for garage conversions, additions, sunrooms, workshops, and rooms the main system never reached. We size the head for the actual load rather than defaulting to the largest unit available.

Ice on the coil means either airflow is restricted or refrigerant charge is low. A clogged filter, a dirty blower wheel, closed vents, or a collapsed duct will do it. So will a refrigerant leak. Repeatedly thawing and restarting the system without finding the cause puts the compressor at risk.

A standard residential changeout in Mountain Home is typically one day. Jobs involving ductwork modifications, attic access issues, or electrical upgrades can run into a second day. We give you the realistic timeline before scheduling.
