Common Heat Pump Problems

While heat pumps are incredibly reliable systems, they can develop issues over time. Being aware of some common heat pump problems can help you properly address them, restoring comfort and reversing any damage caused by heat pump issues.

In the latest blog post from Evergreen Heating & Air, we’ll discuss some of the most common heat pump issues to help you troubleshoot and resolve them effectively. Contact us today to schedule heat pump services in the Waco, TX area.

Constant Running

When performing as intended, heat pumps should run in cycles. They should turn on and run for roughly 10-15 minutes, before shutting off until it’s time to start another cycle. However, a common heat pump problem is when the unit runs continuously without cycling off.

A heat pump running constantly can occur due to several reasons. Some common reasons include a malfunctioning thermostat, a refrigerant leak, or a faulty compressor. When a heat pump runs non-stop, it not only places unnecessary stress on the unit but also leads to inefficient operation and increased energy consumption.

Reach out to your trusted HVAC professionals to discover the root cause of the problem and schedule the proper heat pump repair services.

Rising Energy Costs

Heat pumps are among the most efficient and effective ways to heat and cool a home. However, as issues develop, they may present themselves in the form of higher energy bills and consumption.

Several factors can contribute to this issue, including a clogged air filter, improper installation, or a malfunctioning component. Regular maintenance and replacing your air filters every 1-2 months can help improve efficiency, but if the problem persists, you should seek professional assistance to diagnose and rectify the issue.

Cool Air in Heating Mode or Warm Air in Cooling Mode

A heat pump’s ability to provide both heating and cooling is one of the main reasons they’re so popular throughout Waco and beyond. But if the system isn’t operating correctly while in cooling or heating mode, you may experience comfort issues.

This issue could stem from a malfunctioning reversing valve of the heat pump system, which is responsible for changing the flow of refrigerant to switch between heating and cooling modes. Additionally, low refrigerant levels, a faulty thermostat, or a malfunctioning compressor can also cause this problem.

If your heat pump system is blowing cold air in heating mode or hot air in cooling mode, contact a professional to ultimately discover and address the root cause of the problem.

Short Cycling

Similar to a heat pump that is constantly running, a short cycling heat pump will struggle to keep your home comfortable and will likely result in higher energy costs.

Short cycling refers to the frequent and rapid cycling of the heat pump, where it turns on and off too frequently. This can be caused by various factors, such as an incorrectly sized heat pump, a malfunctioning thermostat, a blocked air filter, or issues with the system’s sensors or controls. If your heat pump is not working to keep your home comfortable because it is short cycling, turn it off and do not run it again until the issue has been solved. 

Strange Smells

When your heat pump is running well, you shouldn’t notice any smells or odors coming from your vents. Depending on what the smell is, you may be experiencing a number of different issues.

For example, a musty smell could indicate mold or mildew growth within the system or your ductwork, while a burning smell is likely due to an electrical issue.

It is crucial not to ignore these smells, as they can indicate very serious issues that require immediate attention.

Loud Noises

While you may hear the slight hum or whoosh of air from your heat pump during operation, loud or unusual noises can be cause for concern. If your heat pump is making loud, unusual noises during operation, it may be indicative of an underlying problem.

Common noises include grinding, rattling, banging, or squealing sounds. These noises can be caused by various issues, such as loose components, a failing motor, a damaged fan blade, or a worn-out compressor.
