Heat Pump Repair in Killeen: Checks, Costs and Who Can Do It

A heat pump is an air conditioner that can run in reverse, so most repairs match AC prices: $150 to $650 for a typical repair and $3,800 to $8,200 for a new unit installed (national ranges, HomeGuide, read November 11, 2026). The extra parts are the reversing valve and the defrost controls.

Checks before you call

  1. Thermostat mode. HEAT or COOL as needed, fan AUTO. “EM HEAT” runs the backup strips only and costs more to run.
  2. Filter and vents. A clogged filter causes icing in both seasons.
  3. Breakers. There are usually two: the outdoor unit and the air handler.
  4. Outdoor unit. Clear leaves and anything blocking airflow.

Repair or replace

A new heat pump runs $3,800 to $8,200 installed. A compressor at $600 to $2,500 on an older, out-of-warranty unit is the point to ask for a replacement quote as well. The replacement cost page has the comparison, and the permit guide covers what the City of Killeen requires for a changeout.

Heat pump repair questions

How much does heat pump repair cost in Killeen?

A heat pump shares most of its parts with an air conditioner, so repairs fall in the same national range of $150 to $650 (HomeGuide, read November 11, 2026). A capacitor runs $100 to $250 and a compressor $600 to $2,500. These are national figures, not Killeen quotes.

Is frost on my heat pump in winter a problem?

A light frost that clears by itself is normal: the unit runs a defrost cycle. A unit encased in ice, or one that never clears, has a fault such as a failed defrost control, a stuck fan or low refrigerant, and needs a contractor.

Does replacing a heat pump need a permit in Killeen?

The City of Killeen’s fee schedule lists a mechanical permit at $50 per unit for residential repair and improvement work, a line that includes condenser and furnace replacement (FY 2026-2027 fee schedule, read November 11, 2026). Ask the contractor to confirm the permit for a heat pump changeout.
