Heat Pump Repair
A heat pump not heating in Parker, CO can be normal for a few minutes or a sign of a real fault. Heat pumps pull heat from outdoor air, and on cold Colorado nights they work hard. Here is how to tell defrost from a frozen heat pump or a failed part.
Call (303) 647-3227
In cold, damp weather, frost builds on the outdoor coil. The heat pump switches to defrost for a few minutes. You may see steam outside and feel cooler air inside. This is normal.
If the outdoor unit is covered in thick ice that does not clear, the defrost system may have failed. A frozen heat pump cannot move heat.
Most heat pumps have backup electric heat for very cold days. If aux heat does not come on, the house may fall behind on the coldest nights.
This valve switches the system between heating and cooling. If it sticks, the heat pump may blow cool air in heat mode.
✓
Set the thermostat to Heat, not Cool or Auto, and check the set point.
✓
Replace the indoor filter.
✓
Clear snow and leaves from around the outdoor unit. Do not chip ice off the coil.
✓
Check the breaker for both the indoor and outdoor units.
Call if ice stays on the outdoor unit for more than a couple of hours, if the air is cool for long periods, or if aux heat never seems to run. Cold-climate heat pumps are more common in Parker, Colorado now, and contractors here work on them often.
