Heat Pump Repair & Installation
Heat pumps are complex systems — they heat in winter, cool in summer, and require technicians who understand both modes. Urgent HVAC Service connects homeowners with certified heat pump specialists in 7,296 cities nationwide.
Common Heat Pump Problems
Heat pumps fail differently than standard AC units or furnaces. These are the issues heat pump technicians diagnose most frequently — and why brand-specific training matters.
When a heat pump stops producing heat, technicians check the reversing valve (the component that switches between heating and cooling modes), defrost control board, outdoor coil sensor, and refrigerant charge. Each failure mode produces different symptoms.
Heat pump cooling failures mirror standard AC problems: low refrigerant, dirty coils, failed capacitor or contactor. The added complexity is ruling out reversing valve issues, which require a heat pump specialist rather than a general AC technician.
Heat pumps run a defrost cycle in winter — but if the defrost board, outdoor sensor, or reversing valve fails, ice builds up on the outdoor coil and efficiency drops sharply. A frozen outdoor unit in winter is not always normal.
A heat pump stuck in heating or cooling mode regardless of thermostat settings almost always points to a failed reversing valve or solenoid. This component is unique to heat pumps and requires a technician familiar with reversing valve diagnostics.
A heat pump that's running longer than normal, struggling to maintain setpoint, or switching to backup heat more often than expected is working inefficiently. Low refrigerant, dirty coils, or a failing compressor are the most common causes.
No-start failures on heat pumps can involve the same components as standard AC (capacitor, contactor, thermostat wiring) plus heat-pump-specific issues like communication errors between the air handler and outdoor unit in multi-stage systems.
Service Coverage
From emergency no-heat calls to new system installation, here's what heat pump technicians in our network handle.
Heat pumps benefit from seasonal tune-ups before both summer and winter — coil cleaning, refrigerant check, defrost board test, reversing valve verification, and filter service. Semi-annual maintenance extends system life significantly.
How It Works
Heat pumps require technicians who understand both heating and cooling operation. Our network matches you with specialists in your area — not general HVAC technicians unfamiliar with heat pump diagnostics.
Tell us what mode it's failing in, what symptoms you're seeing, and your system type — central heat pump, mini-split, or geothermal. More detail means a better match.
We connect you with heat pump specialists actively serving your city — not technicians from the next county who primarily work on gas furnaces.
Talk directly with the technician about what the diagnostic involves, expected timeline, and whether parts may need to be ordered before committing to anything.
Service Coverage
Heat pump service is available in 7,296 cities across all 50 states. Our network includes technicians experienced with air-source, ductless, and geothermal systems.

Questions Answered
Common questions about heat pump repair, costs, efficiency, and whether a heat pump is right for your climate.
A heat pump moves heat rather than generating it. In summer, it moves heat from inside to outside (like an AC). In winter, it extracts heat from outdoor air — even in cold temperatures — and moves it indoors. This makes heat pumps 2–4× more efficient than electric resistance heating. The key component that allows it to switch modes is the reversing valve, which is unique to heat pumps and the source of many mode-specific failures.
Modern cold-climate heat pumps (also called "hyper heat" or low-ambient units from Mitsubishi, Bosch, Daikin, and others) can extract heat efficiently at temperatures as low as -13°F to -22°F. Older heat pumps lose efficiency below 30–35°F and rely heavily on backup electric heat strips. If your heat pump is over 10 years old and you live in a cold climate, upgrading to a cold-climate model may dramatically reduce your heating bills.
Several causes: the system may be in defrost mode (normal — it temporarily blows cooler air to melt ice off the outdoor coil), the reversing valve may be stuck in cooling mode, refrigerant may be low, or backup heat strips may not be activating. If it's not a brief defrost cycle, call a technician — running a heat pump in the wrong mode in winter causes compressor stress.
Common repairs: capacitor replacement $150–$300, reversing valve replacement $400–$800, refrigerant leak repair and recharge $350–$700, defrost board $250–$500, compressor $1,000–$2,500+. Heat pump repair often costs more than equivalent AC repair because of the added components and the need for specialists. Get a written estimate after diagnosis.
If the system is under 10 years old and the repair is straightforward (capacitor, defrost board, refrigerant), repair usually makes sense. If it's over 15 years old, uses R-22 refrigerant, or needs a compressor or reversing valve, replacement math often favors a new high-efficiency system — especially with current rebates for cold-climate heat pumps under the Inflation Reduction Act.
Technicians in our network service all major heat pump brands including Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Daikin, Mitsubishi, Fujitsu, LG, Bosch, and Bryant. Ductless mini-split and multi-zone systems are widely covered. Mention your brand and model when you call to confirm specialist availability in your area.
A mini-split (ductless mini-split) is a type of heat pump — it uses the same heat transfer technology but delivers conditioned air directly to rooms without ductwork. Central heat pumps use existing duct systems. Mini-splits are common for additions, garages, older homes without ducts, and zone control. Both use reversing valves and share the same diagnostic complexity as traditional heat pumps.
