Heat Pump Repair in La Vernia, Texas

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.

For most La Vernia winter weather, yes. During a hard freeze the auxiliary heat supplements it, which is by design. The system should still be doing the majority of the work above freezing.

Yes. Mini split faults are usually communication or inverter board issues rather than mechanical failures, and they need a technician who reads the manufacturer's code tables. Call (833) 435-6611 with the code and the model number.

Twice a year is the standard: cooling in spring, heating in fall. Texas systems run far more hours than equipment in cooler states, so annual-only service tends to let small problems mature into breakdowns. Details are on our La Vernia AC tune-up page.

Size is determined by a load calculation, not square footage alone. Insulation, window area and orientation, ceiling height, duct condition, and shading all change the answer. We run that calculation as part of every replacement quote, because an oversized unit short cycles and leaves the house humid.
