Why Is My Heat Pump So Loud?

by | Jan 15, 2020 | Heating | 0 comments

Strange or loud noises coming from your HVAC system can be one of the most unsettling and stressful sounds you encounter as a homeowner. Loud noises generally mean something has gone wrong, which in turn can mean needing HVAC repairs or worst-case scenario, having to do without for a while. We’ve compiled this list of possible sounds you are hearing from your heat pump and what they mean.

3 Reasons Why Your Heat Pump Is So Loud


Whistling Noises

If you’re hearing a whistling sound, this usually means air is rushing in quickly through a small opening. This could mean a variety of issues such as; dirty air filters on your system or even possibly from objects being placed in front of air registers and vents restricting the airflow going in or out.

Jarring, Clanking, Metal-to-Metal Sounds

Sometimes heat pumps make loud noises that sound like metal hitting metal inside the unit. You should turn your unit off right now and do a quick inspection of the fan. These “metal to metal” sounds are most often the result of fan blades knocking against something inside the unit, such as a chunk of ice or possibly another component.

Buzzing, Bubbling, and Screeching Sounds

A soft buzzing sound coming from your heat pump is typically a normal sound to expect. Internal coils and other components make a smooth buzzing sound as they run. However, a bubbling sound could be due to low refrigerant, so if you hear this sound- be sure to check the level of refrigerant. And, if your motor bearings get dirty, this can cause a high-pitched screeching sound. If you’re hearing these sounds they are not normal and warrant a call to your HVAC technician right away.
