3 Reasons for a Noisy Heat Pump

December 18, 2020

If your heat pump is making a lot more noise than usual, there can be a few reasons why. Heat pumps tend to make unusual sounds, but there are three sounds that you need to have investigated.

1. Motor or Compressor Issues

There are sounds that indicate something has gone wrong in your outdoor unit. Loud pops, squealing or buzzing sounds indicate the motor or compressor needs attention. If you hear rattling, vibrating, or metallic noises, the sound is likely caused by parts that have come loose and that are interfering with the fan.

Buzzing or rattling noises can also mean there’s a refrigerant leak in your outdoor unit. If the filter is misaligned, it can create a whistling noise. Electrical problems cause buzzing and humming sounds. Broken valves can make vibrating, hissing, and whooshing noises.

2. Problems in Ducts

A few different things can cause noisy ducts. If the vibration dampening is damaged, you’ll hear popping and creaking noises. A whistling sound indicates there’s either something obstructing the ducts or there are leaks. Animals in your ducts will cause scratching, humming, and gnawing sounds.

3. Indoor Air Handler Issues

Your indoor air handler can also make unusual sounds when parts are failing. You may hear a clicking sounds when there’s damage to belts, valves, fans, crankshaft, pistons, rods, or thermostat. If you hear buzzing and humming coming from the indoor air handler, it’s likely an electrical problem.

If the filter has fallen out of place, you can hear a whistling noise. Refrigerant leaks and loose parts will cause buzzing and rattling noises. You should have a refrigerant leak looked into as soon as possible because it’s harmful to the health of your family.
