What’s That Noise Coming From My Heat Pump in Newton, MS?

From soft humming and clicking to brief buzzing and whirring, heat pumps make various noises during normal operation. However, there are some sounds you should never ignore. If you hear a strange or unusual noise coming from your heat pump, it may be time to call an HVAC professional in Newton, MS.

Hissing or Gurgling

When there’s a leak in your heat pump system, refrigerant escapes and rapidly vaporizes into a gas. This produces a distinct hissing sound, but you may also hear gurgling or bubbling. Not only are refrigerant leaks damaging to your equipment, but they can also be hazardous to your health.

A less common culprit is a stuck reversing valve. The reversing valve switches your heat pump between heating and cooling modes, but it can occasionally become stuck. When it does, you may notice a constant hissing or whooshing noise.

Grinding or Squealing

If your heat pump sounds much louder than usual, it could be a sign you’re falling behind on HVAC maintenance. Without regular cleaning and lubrication, some parts may begin wearing out and grinding against one another.

Frequent squealing or squeaking is another common sign of belts, bearings and other components that need servicing. A sharp, high-pitched squeal can also indicate more serious problems, such as a failing motor or compressor.

Rattling or Banging

A loud banging, rattling or thumping noise is usually a sign of trouble. If you’re lucky, the racket may just be from twigs or other debris stuck in the heat pump’s fan blades. The fan itself may also be loose or off-balance.

Unfortunately, these noises may also be warning signs that major components are malfunctioning. Failing to address these issues right away could make the situation even worse, potentially necessitating a heat pump replacement.
