You’ve likely heard your heat pump making some noise as it keeps your Plano, TX home comfortable. It’s usually just the soft hum that you’d expect to hear during normal operation, but sometimes, you may hear additional sounds that indicate something isn’t quite right. Let’s review some heat pump sounds and what they may indicate for your system.
1. A Quick Hiss at Startup or Shutdown
You may hear a brief hissing noise while your heat pump starts or stops. This typically means the reversing valve switches over to heating or cooling. That’s generally a normal operational noise, and you have nothing to worry about unless it occurs frequently or continues for too long. A continuous hissing sound likely indicates a refrigerant leak
2. Banging or Rattling
A banging noise in your outdoor unit may indicate loose parts. Otherwise, you may have debris trapped in there, or a fan blade may be a little wobbly. Though sometimes trivial, ignoring a rattle that won’t go away risks more serious damage.
3. Buzzing or Humming Noises
An ongoing buzzing or humming could signal an electrical issue, such as a faulty capacitor that might be on its last legs. It could also indicate a fan motor issue or even a compressor problem. Electrical issues can be dangerous, so it’s best to consult a repair professional.
4. Gurgling or Bubbling Sound
If you hear gurgling or bubbling noises, it might mean a leak in the refrigerant lines. Your system needs refrigerant for the heat transfer process, and a leak will cause your system to work harder and be less efficient. Refrigerant is hazardous to touch and inhale, so do not attempt to fix this yourself.
