Why Is My Heat Pump So Noisy in Alton, IL?

It may startle you to hear your heat pump suddenly making noises that it hadn’t made before. Naturally, you may wonder why it’s making such noises and how they will affect your home comfort. Read on to learn why your heat pump in Alton, IL, is so noisy.

Humming and Clicking

A gentle hum is the standard heat pump noise when running a cycle. It’s normal and doesn’t point to anything worrisome. If you haven’t used your heat pump in some time, or if the system is either starting or completing a heating or cooling cycle, you may also temporarily hear some clicking noises.

Bubbling, Hissing or Gurgling

These sounds are among the characteristic signs of a refrigerant leak. Under ordinary circumstances, refrigerant should fill up your heat pump’s refrigerant lines as it moves through them.

If the lines have any type of damage and refrigerant leaks out, air will move in and displace what leaked out. These air bubbles are the source of the noises in this case.

It’s essential to replace any refrigerant your heat pump loses, but you should never attempt to do so yourself. Call an HVAC service technician and ask them to do it as part of your repair service or maintenance appointment.

Banging or Thumping

If you hear this noise, the most likely cause is a loose fan blade. That blade may be striking some other part of your heat pump, or some ice may have formed near the fan, leading the fan blades to hit it.

The more you keep your ears open and listen for any abnormal sounds, the more likely you’ll detect issues with your heat pump early. For assistance with your noisy heat pump, call Den-Son Inc. Cooling & Heating and schedule repair services in Alton, IL.
