When it comes to heating and cooling your home, a heat pump is one of the most reliable and efficient options available.

However, if you’ve noticed that your heat pump seems stuck in one mode—either heating or cooling—it can be both inconvenient and stressful. In this article, we’ll explain why your heat pump could be stuck in one mode and provide tips on troubleshooting and fixing the issue. Read on to learn more.

What is a Heat Pump?

A heat pump is an energy-efficient device that uses the same technology to cool and heat a space. It transfers air from outside of your home into the indoors, cooling or heating it depending on the season.

Heat pumps are generally used in climates with milder temperatures since they may struggle to reach the desired temperature in extreme weather conditions.

Additionally, heat pumps use electricity rather than burning fossil fuels like natural gas or oil, so they can help reduce your carbon footprint while providing an efficient way to maintain comfortable indoor temperatures.

With that said, let’s explore all the reasons why your heat pump may be stuck in one mode.

The Reversing Valve is Broken

A faulty reversing valve is the most common reason for a heat pump getting stuck in one mode.

The reversing valve, which can be found on the outside unit of your heat pump, is responsible for switching between heating and cooling modes. When this valve isn’t working properly, it’s unable to change modes and will only stay in one setting.

If you suspect that your reversing valve is broken or malfunctioning, it’s best to contact a professional HVAC technician as soon as possible. They’ll be able to diagnose the issue and recommend repairs or replacement parts if necessary.

In some cases, it may be a matter of resetting the system after power has been interrupted or restored. If that’s the case, you can fix the issue on your own.

The Thermostat is Malfunctioning

Another possible cause of a heat pump getting stuck in one mode is a broken or incorrectly programmed thermostat.

Your thermostat should be set to an appropriate temperature that corresponds with the current season—cooler temperatures for summer and warmer ones for winter. If it’s set at a lower temperature than what’s needed, it can cause your heat pump to struggle and stay stuck in cooling mode.

If you suspect that your heat pump’s thermostat is malfunctioning or not programmed correctly, try resetting it and then changing the temperature setting before running another test.

It is also worth investing in a new programmable thermostat, which can help you save energy and money by ensuring that the temperature is always set correctly.

There’s a Refrigerant Leak

Finally, a refrigerant leak is another potential issue that can cause a heat pump to get stuck in one mode. Refrigerant is necessary for the system to function correctly and keep your home comfortable. Over time, leaks can develop due to corrosion or other damage.

If you’ve noticed cool air coming from the vents even when you’ve set your thermostat to a higher temperature, that could indicate a refrigerant leak.

In this case, it’s best to contact a professional HVAC technician as soon as possible so they can inspect your heat pump and repair any leaks or damages.

It’s also important to remember that any repairs involving refrigerants must be done by a certified technician, as they contain hazardous chemicals that can be dangerous if handled incorrectly.

When Should You Call an HVAC Specialist?

Although some of the issues mentioned above can be fixed without professional help, it’s always best to consult with a qualified HVAC technician if you’re unsure about what’s wrong or if you suspect there could be deeper problems.

They’ll have the knowledge and expertise to diagnose and fix any issue with your heat pump—from minor thermostat adjustments to more complex repairs such as replacing parts or repairing refrigerant leaks.

They’ll also be able to provide advice on how to maintain your system so that it runs efficiently and effectively for years to come.
