Common Heat Pump Problems


As homeowners, we rely on our HVAC systems to keep us comfortable year-round. For those of us with heat pumps, we know they’re an efficient and cost-effective way to heat and cool our homes. However, just like any other mechanical equipment, heat pumps can develop problems over time, especially if they aren’t maintained regularly. In this blog post, the technicians at Robinson Heating & Air Conditioning discuss some of the common heat pump problems that Middletown, OH homeowners face, and we’ll provide some heat pump troubleshooting tips for preventing them.

Heat Pump Maintenance Needs

Heat pumps require more maintenance than single-season systems, such as air conditioners or furnaces, because they operate year-round, providing both heating and cooling functions. This continuous operation subjects the heat pump’s components to more wear and tear, which can lead to common heat pump problems.

To keep your heat pump functioning at its best, it’s essential to schedule regular maintenance checks with a professional HVAC technician. They will inspect, clean, and service the unit, addressing any potential issues before they become costly repairs or lead to system failure.

Low Refrigerant

One of the most common heat pump problems is a low refrigerant level. The refrigerant is the fluid that circulates through the heat pump and absorbs heat from one area to move it to another. If the level of refrigerant is low, the heat pump won’t be able to transfer heat as efficiently, and you may notice lower-than-normal temperatures or reduced airflow. If you suspect that your heat pump is low on refrigerant, you should call a professional to recharge the unit and inspect for any leaks in the system.

Thermostat Problems

Another common issue with heat pumps is problems with the thermostat. The thermostat is the device that controls the temperature of your home, and if your heat pump system isn’t connected to the thermostat properly, it won’t be able to regulate the temperature effectively. Ensure that your thermostat is installed correctly. You can also check the batteries and settings to make sure that it’s functional.

Dirty Coils

Another problem that heat pump owners face is the build-up of dirt and debris on the evaporator and condenser coils. Heat pumps use these coils to transfer heat, and if they become dirty or clogged, your system could fail to produce warm or cool air. To help prevent this problem, you should clean the coils regularly or have a professional do it for you. However, the single most important thing homeowners can do to prevent dirty coils is to change their HVAC air filter on a regular basis. We recommend replacing it on a monthly basis.

Electrical Issues

Heat pumps rely on a network of electrical components to function properly, including motor capacitors, contactors, and relays. These components can wear out over time, causing electrical issues that can affect the proper function of your system. Check your electrical connections for any loose or damaged wires, and have a professional perform regular maintenance to keep your electrical components in optimal condition.

Broken Reversing Valve

The heat pump reversing valve is responsible for switching the heat pump between heating and cooling modes. When this valve becomes stuck, it can cause your heat pump to malfunction, either by not providing the desired temperature or by being unable to switch modes. Symptoms of a stuck reversing valve include inconsistent room temperatures, the heat pump blowing cold air when set to heat, or blowing hot air when set to cool. If you suspect that your heat pump’s reversing valve is stuck, it’s essential to contact a professional HVAC technician to diagnose and resolve the issue.
