Common Heat Pump Services Questions
This usually means the reversing valve is stuck in cooling mode. The reversing valve switches refrigerant flow direction to provide heating or cooling. If it fails, the system stays in one mode. Reversing valve replacement costs $400-$800 and takes 2-4 hours. Call (303) 351-1667 for diagnosis.
Light frost is normal, but heavy ice buildup indicates a problem. Heat pumps have a defrost cycle that melts ice every 30-90 minutes. If ice isn’t melting, the defrost board, sensor, or reversing valve may have failed. This needs immediate repair to prevent compressor damage.
Auxiliary (backup) heat should only run when temperatures drop below ~35°F or when recovering from a setback. If it runs constantly, your heat pump may not be working, or the thermostat is misconfigured. Aux heat uses expensive electric resistance strips, so this needs immediate attention to avoid high bills.
Modern cold-climate heat pumps work efficiently down to 0°F and can operate to -15°F. Older models struggle below 35°F. Many Colorado homes use dual-fuel systems – heat pump for mild weather, gas furnace for extreme cold. This provides efficiency and reliability. We can assess if your heat pump is sized correctly for our climate.
Common repairs: Capacitor $150-$250, Defrost board $300-$500, Reversing valve $400-$800, Compressor $1,500-$2,500. Most repairs we complete are $200-$600. We provide upfront pricing before starting work. Emergency service available 24/7 at (303) 351-1667.
