Heat pumps are an essential part of many homes, particularly those in mild climates. If you happen to be outdoors near a heat pump unit, you’ll probably notice that it’s fairly loud. This shouldn’t be a cause for concern, however, as loud sounds are normal for heat pumps, especially during the winter season when it could shift into defrost mode at any time. However, if you begin to hear noises other than the ones you’re used to, it’s possible that something may be amiss
In this article, the experts on new air conditioning from R.A. Biel Plumbing & Heating reveal the meanings behind the various heat pump noises you may hear.
If you hear a squealing sound coming from your heat pump, this could possibly have something to do with the system’s screw compressors. While squealing noises are normal for the compressors, make sure to have a professional inspect the system if the sounds started just recently despite no changes being made to the heat pump. It’s possible your motor could be going out or the compressor is putting your refrigerant under too much pressure.
Bubbling is another loud sound that you may hear from your heat pump system. This sound usually occurs when outdoor air enters your drain hose. This is a common occurrence if your home or apartment is completely closed off and the wind is strong. If you’re concerned about the bubbling noises you hear, there’s no harm in scheduling an appointment with a heat pump professional to have it checked.
On the other hand, hissing sounds are caused by the discharge of humidified air and aren’t really a cause for concern. As before, however, if this noise concerns you, don’t hesitate to call an expert for an inspection.
Loud Noises During Startup or Shut Down
Heat pumps usually make loud noises when they’re starting up or powering down. If you aren’t accustomed to these sounds, it’s understandable to be alarmed. However, keep in mind that these noises are typical and aren’t a cause for concern. If they’re accompanied by previously unheard noises, however, you should call a professional like the HVAC and plumbing repair pros of R.A. Biel Plumbing & Heating.
If you hear loud noises coming from your heat pump system that sound like metal hitting metal, turn the fan off immediately and inspect it. This sound is often the result of the fan blades hitting debris that ended up inside the unit. If the fan is allowed to continue running, it could end up breaking or causing damage to other components of the system.
