A heat pump moves heat instead of burning fuel. In winter it pulls heat out of the outdoor air and brings it inside. On a cold, damp morning frost forms on the outdoor coil. The unit then runs a short defrost cycle, and you may see steam rise from it. That is normal.
Most Parker homes pair the heat pump with a gas furnace or electric heat strips as backup. On the coldest nights the backup takes over. Cold-climate heat pumps keep heating at lower temperatures than older models, but backup heat still has a job here.
A few parts cause most heat pump repair calls. Knowing the names helps you follow what the contractor tells you.
A defrost board and a sensor on the outdoor coil decide when to melt the frost. When one fails, ice builds up until the coil is a solid block and the heat pump cannot move heat.
This valve switches the system between heating and cooling. A stuck valve leaves the heat pump in one mode, so it blows cool air in winter or warm air in summer.
The run capacitor helps start the compressor and the outdoor fan. A weak one, a burned contactor or a failed fan motor stops the outdoor unit even though you hear it trying.
Low refrigerant means a leak somewhere, and it makes the unit work harder for less heat. The compressor is the heart of the system. It is the most expensive part to replace, so catching other problems early protects it.
1.
Set the thermostat to Heat, not Emergency Heat, and a few degrees above room temperature.
2.
Replace the thermostat batteries if the screen is blank or dim.
3.
Check the breaker panel for a tripped breaker for the outdoor unit or the air handler.
4.
Pull the indoor filter. If it is gray and packed, replace it.
5.
Clear snow, leaves or ice that has piled against the sides or top of the outdoor unit.
6.
Watch the outdoor unit for 15 minutes. Frost that clears on its own is normal. A thick block of ice that stays is not.
Stop there. Do not chip ice off the coil, pour hot water on it or open the outdoor panel. The fins bend easily and the unit holds high-voltage parts.
Still iced over or blowing cool: (303) 647‑3227Parker sits higher than Denver, and winter nights often drop well below freezing. Snow drifts against outdoor units on the windy side of the house, and dry air leaves dust on the coils. Many newer homes in Stroh Ranch, Meridian and Stonegate have a heat pump paired with a gas furnace, so a heat pump problem can hide behind the furnace for weeks.
If your heat pump runs but the house stays cold, see heat pump not heating. If the whole system is down, heating repair covers furnaces and boilers too.
Talk to a heat pump contractor: (303) 647‑3227An older heat pump with a failed compressor or repeated refrigerant leaks is often a candidate for replacement. Newer models use R-454B refrigerant, and cold-climate models heat better on Parker nights. Xcel Energy and federal programs offer rebates and credits on qualifying heat pumps. Ask the contractor which ones apply to your home and how to claim them.

Call now, any time: (303) 647‑3227In heat mode the air from a heat pump feels cooler than furnace air, which is normal. Air that is truly cold usually means a defrost cycle, a stuck reversing valve or low refrigerant. If it lasts more than a few minutes, call.
A light frost that clears during a defrost cycle is normal. A thick layer of ice that covers the coil for hours points to a defrost control, fan or refrigerant problem.
Aux heat should help on the coldest nights or after a defrost cycle. If it runs most of the day, the heat pump is not keeping up. That can be a refrigerant leak, a failed outdoor fan or a thermostat set up wrong.
Yes. Cold-climate heat pumps keep heating well below freezing, and most Parker homes also have backup heat for the coldest nights.
