4 Most Common Heat Pump Problems

The most common issues that homeowners encounter include refrigerant leaks, frozen coils, electrical issues, and thermostat malfunctions.

1. Refrigerant Leaks

Refrigerant leaks are among the most common heat pump issues faced by homeowners in the US. These leaks occur when the refrigerant lines that carry coolant through your heat pump develop cracks or holes, allowing the refrigerant to escape.

To spot a potential refrigerant leak, you should be on the lookout for any signs of reduced system performance, such as your heat pump constantly running without achieving desired indoor temperatures or lukewarm air coming from vents when it should be hot or cold.

Additionally, keep an ear out for hissing noises coming from the indoor or outdoor unit – this could indicate escaping refrigerant. In some cases, you might even notice frost build-up on evaporator coils due to insufficient coolant levels.

2. Frozen Coils

Another common heat pump problem that homeowners may encounter is frozen coils. This could be the result of a number of factors such as, improper refrigerant levels, malfunctioning of the blower fan, or even a dirty filter. 

To fix this issue, it’s important to first turn off your heat pump and let the coils thaw out completely. Once they are fully defrosted, you should check all the possible causes of the freezing and address them accordingly.

This could involve replacing dirty air filters, adding more refrigerant (if there is a leak), or repairing/replacing any necessary components like the blower fan.

3. Electrical Problems

Another common issue homeowners face with their heat pumps is electrical problems. Electrical issues can range from faulty wiring to broken capacitors, both of which can prevent your heat pump from functioning properly.

You can avoid the following issues by making sure your heat pump is installed properly and the wiring is up to code. Regular maintenance, like cleaning or replacing old filters, can also help identify any potential electrical problems before they become serious issues.

Remember that electricity can be dangerous, so if you suspect an issue with your heat pump’s electrical system, it’s best to contact a licensed professional immediately for assistance.

4. Thermostat Issues

Thermostat issues can create a lot of discomfort in your home. If your heat pump isn’t turning on or off when it’s supposed to, or if the temperature reading is incorrect, it could be a thermostat problem.

Sometimes, all that is needed is simply recalibrating the thermostat to make sure readings are accurate.

One common issue with thermostats is improper placement. Locating your thermostat near doors and windows can result in inaccurate temperature readings as drafts from airflow through gaps may cause the heating and cooling system to kick in more often than necessary leading to higher energy bills than usual.

Therefore,it’s important that homeowners place their thermostats away from any areas where drafts may occur such as hallways, open doorways or areas of high traffic within homes for optimal performance.

Fixes For Each Heat Pump Issue  

To address refrigerant leaks, a qualified technician will need to replace or fix any damaged components; for frozen coils, simply thawing them out can often solve the issue.

If your heat pump is experiencing electrical problems, it’s essential to have a licensed electrician take a look and fix any wiring issues they find.

Repair Or Replace Refrigerant Leaks

One common issue that homeowners may face with their heat pump is refrigerant leaks. These leaks can cause the system to work harder and less efficiently, resulting in higher energy bills and a decreased lifespan for the equipment.

A technician will first locate the source of the leak using specialized tools and then repair or replace any damaged components. Ensuring that your heat pump is running at peak efficiency not only saves you money but also helps protect the environment and local ecosystem by reducing greenhouse gas emissions.

Thaw Frozen Coils

Another common issue faced by homeowners with heat pumps is frozen coils. This can happen when the outdoor unit is exposed to extremely low temperatures or there’s a blockage in the air filter, which restricts proper airflow and causes your system’s evaporator coil to freeze up.

To solve this problem, turn off your heat pump immediately and let it thaw out for at least 24 hours or more before you turn it back on. If you cannot wait that long, try using a hairdryer on a lower setting to speed up the process slightly.

It’s worth checking your air filter regularly to make sure it’s not clogged and reducing airflow into the system.

Address Electrical Issues

Electrical issues are another common heat pump problem. These can range from simple wiring problems to more complex issues with the control board or motor.

If you suspect you’re facing an electrical problem with your heat pump, it’s important to get it addressed as soon as possible. Depending on the specific issue at hand, it may be best to call in a professional technician or an electrician to diagnose and repair the problem safely and efficiently.

Some examples of common fixes for these types of issues might include replacing faulty wires or switches, installing new fuses or circuit breakers, calibrating sensors or thermostats, or even replacing entire components like motors or control boards.

Calibrate Or Replace The Thermostat

It might just be a problem with your thermostat! When a thermostat isn’t working properly, it can cause your heat pump to run longer than necessary or not at all.

If you still have problems after adjusting the temperature settings, it may be time to calibrate or replace the thermostat. A thermostat that malfunctions can also lead to uneven heating and cooling throughout your home, which can be frustrating and costly.

To avoid these issues, consider investing in a programmable thermostat that will enable you to set different temperatures for different times of day based on your schedule.


In conclusion, understanding the most common heat pump challenges and their fixes can save homeowners a lot of time and money. From refrigerant leaks to frozen coils, electrical issues to thermostat malfunctions, several things could go wrong with your heat pump.

However, by following the outlined fixes for each problem, you will keep your home comfortable all year round without breaking the bank on repairs or replacements.
