Diagnosing and Troubleshooting the Common Heat Pump Issue
If you notice your heat pump blowing cold air, it can feel like a puzzling problem that’s hard to solve. Many homeowners often wonder why their system isn’t working correctly and how they can get it back in running like normal. This blog explains common issues to help you diagnose and troubleshoot the problem with your heat pump.
The first step is to check your thermostat settings. It’s possible that the heat pump was inadvertently switched to the cooling mode or the fan was set to the “ON” mode instead of the “AUTO” position. If neither of these are the issue, then it’s likely a faulty outdoor temperature sensor or a stuck reversing valve is the problem.
A faulty outdoor temperature sensor can cause the unit to never enter the heating mode during cold weather. In this case, the heat pump will only blow cold air. To fix this issue, the outdoor temperature sensor needs to be replaced with a new one. The same holds true for a faulty reversing valve, which restricts the flow of warm or hot refrigerant to the indoor coil when the compressor is turned on. When this happens, the heat pump will only blow cold air. Fixing this issue requires replacing the reversing valve on the system.
Alternatively, a problem with the compressor or a refrigerant leak in the system can also cause the heat pump to blow cold air. To troubleshoot this issue, the compressor should be inspected for any damage or problems. Additionally, a refrigerant leak is typically easy to spot with the help of a professional technician who can run a rapid leak test.
