Why is My Panasonic Heat Pump Making Strange Noises?

Why is My Panasonic Heat Pump Making Strange Noises?

There could be various reasons why your Panasonic heat pump is making strange noises. Here are some common causes and potential solutions:


  1. Normal Operating Sounds: Heat pumps can make some normal operating sounds, such as a low hum or soft clicking, as they cycle through different modes. Check the user manual to understand the typical sounds your heat pump might make during operation.


  2. Vibrations or Loose Parts: Check for any loose panels, screws, or components. Vibrations during operation can sometimes cause parts to become loose. Tighten any loose screws or panels and see if the noise persists.


  3. Fan Issues: The indoor or outdoor fan might be causing the noise. Inspect the fans for any obstructions, such as debris or loose parts. If the fan blades are hitting something, adjust them carefully. If the noise continues, it could indicate an issue with the fan motor, and you may need professional assistance.


  4. Refrigerant Issues: Strange gurgling or hissing sounds could indicate a refrigerant issue. If there's a refrigerant leak or low levels, it may affect the heat pump's efficiency and generate unusual noises. Refrigerant-related issues should be addressed by a qualified technician.


  5. Expansion and Contraction: During normal operation, the heat pump components may undergo expansion and contraction, especially when transitioning between heating and cooling modes. This can result in popping or clicking sounds. If these sounds are not excessively loud and occur briefly, they are usually normal.


  6. Ice Buildup: In colder climates, ice can accumulate on the outdoor unit during winter. When the heat pump goes into a defrost cycle, you may hear cracking or popping sounds as the ice melts. If the noise persists, or if there's excessive ice buildup, consult a technician to inspect and address the issue.


  7. Motor Issues: If there are issues with the compressor or other motors, it could result in unusual sounds. Motors might produce grinding, screeching, or other abnormal noises when they are malfunctioning. In such cases, professional assistance is recommended.


If you're unable to identify or resolve the issue on your own, it's advisable to contact a qualified HVAC technician to inspect and repair your Panasonic heat pump. Regular maintenance and timely repairs can help ensure the efficient and quiet operation of your heat pump.

I definitely recommend TwinTech!

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
