Heat pump issues can affect heating, cooling, airflow, and overall system performance. Harts can inspect your system, identify what is causing the problem, and explain the repair options before work begins.
Get help when your heat pump blows cool air, struggles in colder weather, or cannot keep your home warm.
Fix cooling problems when your heat pump runs but your home still feels warm, uneven, or uncomfortable.
Diagnose startup problems, breaker trips, faulty parts, unusual noises, or failing components.
Repair problems with airflow, short cycling, constant running, defrost cycles, or uneven temperatures.
Heat pumps work differently than furnaces and standard air conditioners, so heating or cooling problems can come from several parts of the system. Thermostat settings, airflow restrictions, refrigerant issues, defrost problems, outdoor unit conditions, or electrical components can all affect how well the system performs.
Harts technicians inspect the full heat pump system to identify what is causing the issue. Whether your home feels too cold in winter, too warm in summer, or uneven from room to room, we explain the problem clearly and review your repair options before work begins.
Some heat pump issues are easy to notice, like loud noises, ice buildup, weak airflow, short cycling, or a system that will not turn on. Other problems may build slowly and show up as longer run times, higher energy bills, or a system that struggles during colder Pacific Northwest weather.
Harts checks the equipment, thermostat, electrical components, airflow, outdoor unit, and visible system conditions to understand what is affecting performance. From mechanical problems to electrical issues, our team helps you find the right fix for your home.
Heat pump problems can show up during heating season, cooling season, or anytime the system is asked to work harder. Scheduling service early can help identify issues before they lead to larger repairs or poor system performance.

Expert Help
Heat pump issues can be difficult to diagnose because one symptom may come from several different parts of the system. Poor heating, weak cooling, ice buildup, airflow problems, thermostat issues, electrical faults, and worn components can all affect how your heat pump operates.
Heat pump problems often show up as changes in temperature, airflow, sound, or system behavior. A professional diagnosis helps identify whether the issue is coming from the equipment, controls, airflow, refrigerant system, or outdoor unit.
If your heat pump is blowing cold air, struggling in colder weather, or not keeping your home warm, the issue may involve thermostat settings, airflow restrictions, refrigerant problems, defrost operation, electrical components, or backup heat.
A heat pump that does not cool properly may have dirty coils, low refrigerant, airflow restrictions, thermostat issues, outdoor unit problems, or electrical failures. Harts can inspect the system and explain what is affecting cooling performance.
Some frost can be normal during cold weather, but heavy ice buildup or a unit that will not defrost may point to a defrost issue, sensor problem, airflow restriction, refrigerant concern, or outdoor unit malfunction.
Some heat pump problems come from the parts that help the system start, run, cycle, and respond to your thermostat. If one component is failing, the system may stop working, run too often, make noise, or struggle to keep your home at the right temperature.
If your heat pump will not start, loses power, or keeps tripping the breaker, the issue may involve the thermostat, wiring, capacitor, contactor, relay, control board, or another electrical component. Harts can inspect the system, identify the cause, and explain your repair options before work begins.
A heat pump that runs nonstop or turns on and off too often may be struggling to reach the set temperature. Airflow restrictions, thermostat problems, dirty components, refrigerant concerns, equipment wear, or system sizing issues can all affect how often the system runs.
Water near your indoor unit may come from a clogged condensate drain, frozen coil thawing, damaged drain pan, or drainage issue. Harts can inspect the system, find where the moisture is coming from, and explain the repair options before it leads to more damage.
From heat pump troubleshooting to system repairs, homeowners trust Harts for professional service.

Find answers to common questions homeowners ask when a heat pump stops working.
A heat pump may blow cold air because of thermostat settings, airflow restrictions, defrost cycle issues, refrigerant concerns, outdoor unit problems, or electrical components that are not working correctly. A technician can inspect the system and identify what is affecting heat output.
If your heat pump is running but not cooling your home, the issue may involve dirty coils, low refrigerant, restricted airflow, thermostat problems, outdoor unit issues, or electrical failures. Harts can diagnose the problem and explain your repair options.
Light frost can be normal during colder weather, but heavy ice buildup or a system that will not defrost may point to a problem. Defrost controls, sensors, refrigerant levels, airflow, or outdoor unit components may need to be checked.
A heat pump may fail to turn on because of thermostat issues, breaker problems, wiring faults, a failed capacitor, contactor issues, control board problems, or other electrical concerns. If the system will not start, schedule service before trying repeated resets.
Frequent cycling, nonstop running, or short operation may be caused by airflow restrictions, thermostat problems, refrigerant issues, dirty components, equipment wear, or system sizing concerns. A professional diagnosis can help determine what is causing the runtime issue.
Water near the indoor unit may come from a clogged condensate drain, frozen coil thawing, damaged drain pan, or drainage issue. It is best to schedule service before moisture leads to water damage or additional system problems.
Repair may make sense when the issue is isolated and the system is otherwise in good condition. Replacement may be worth considering if the heat pump is aging, inefficient, unreliable, or needs frequent repairs. Harts can inspect your system and explain both options.
Heat pump repair cost depends on the problem, parts, labor, system accessibility, and whether additional approved work is needed. Harts diagnoses the issue first and provides upfront pricing before repair work begins.
