Why Is My Heat Pump in Raleigh, NC, So Noisy?

When the heat pump in your home in Raleigh, NC, operates properly, it makes about as much noise as a typical conversation. However, strange noises can hint at a larger and more urgent mechanical problem with it. Here are some unusual noises your heat pump can make and the reasons for why the system is so noisy:

Banging

Banging noises coming from your heat pump usually mean there’s a problem with its fan. A component in the fan can come loose and hit objects like the heat pump’s fan blades. A foreign object like a chunk of ice can also get inside the heat pump and create loud banging noises as it rattles around.

Vibrating

Vibrating can indicate that a part like the cover panel has come loose and needs tightening. You can place a rubber mat under your heat pump to absorb vibrating noises. You can also prevent these noises by having an HVAC service technician maintain your heat pump at least once a year.

Grinding

Grinding usually indicates a problem like dirty motor bearings. Your heat pump could also have malfunctioning coils or contacts in it. An HVAC service technician can inspect and service these parts to stop the grinding noises.

Gurgling

If you hear a gurgling noise coming from your heat pump, it could have a refrigerant leak. This problem not only creates noticeable gurgling noises but also compromises your heat pump’s ability to heat or cool your home. It requires immediate professional HVAC repairs.

Popping

Loud popping can occur from ductwork expanding because of temperature fluctuations or dirty gas burners in your heat pump. Routine maintenance can ensure your gas burners remain clean. It can also help keep your ductwork sealed and intact.

These factors can cause your heat pump to make loud noises that signal the need for maintenance or repairs. Contact our team at Mitchell Heating & Cooling to learn more about our heat pump services in Raleigh, NC.
