Heat Pump Repair & Replacement

Heat pumps heat and cool a large share of Upstate homes. One system works year-round, so a problem shows up in every season. We know these systems inside and out.

Common heat pump problems

  • Not heating or not cooling
  • Running nonstop in winter
  • Outdoor unit iced over and not defrosting
  • "Aux" or "Emergency heat" running often
  • Reversing valve stuck
  • High winter power bills
  • Loud noises from the outdoor unit
  • Refrigerant leaks

A little frost is normal, a block of ice isn't

In cold, damp weather it's normal for a heat pump to frost up and go into defrost mode now and then. You may even see steam. If the unit is caked in solid ice, or never seems to clear, the defrost controls, sensors, fan or refrigerant charge may be the problem. Call us.

Replacing a heat pump

As an authorized Trane dealer, we install efficient Trane heat pumps sized correctly for your home. A correctly sized system is the difference between steady comfort and a system that short-cycles and wears out early. You'll get a free written estimate and an honest answer about whether repair is the better choice.

Frequently asked

Why is my heat pump blowing cool-feeling air in winter?

Heat pump air is warm but not as hot as a gas furnace, so it can feel cool on your hand. If the house isn't reaching the set temperature, though, something's wrong. Call us.

Should I use emergency heat?

Only if the heat pump itself has failed. Emergency heat runs on electric strips alone and is expensive to use. If you need it, call us to repair the heat pump.

Do you service heat pumps from other brands?

Yes, all major brands.
