If the equipment runs but your home is not warming, begin with the thermostat mode and the indoor temperature trend. Air that feels cooler than furnace air does not necessarily mean the heat pump has failed.
For continuing loss of heat in Littleton, contact Heat Pump Repair Pro. Emergency and same-day service are available.
Check the settings and accessible airflow
Confirm that the thermostat is set to heating. A fan set to run continuously may circulate air between heating cycles. Check an accessible filter according to the equipment instructions and make sure room registers are not blocked.
Do not open panels, change wiring, or handle refrigerant components.
A brief change in air temperature can be normal
During defrost, a heat pump can temporarily change its operation. A short period of cooler air followed by resumed heating is different from a system that remains unable to warm the house.
Record whether heating returns and whether the indoor temperature recovers. If the outdoor unit has persistent ice, see our freezing-up guide.
When service is the next step
Arrange repair if basic observations do not explain the continuing problem. Airflow, thermostat control, refrigerant, or reversing-valve issues can affect heating; the symptom alone does not identify the failed component.
Tell us whether the system previously cooled correctly, when the heating problem began, and whether a thermostat was recently changed.
What if the house warms only on Emergency Heat?
That is useful information to report. It does not prove a specific compressor or control failure. Follow your system instructions and read our backup heat guide.
