Humming, Whooshing and Clicking: What 6 Common Heat Pump Noises Indicate

October 13, 2020

When your heat pump is operating correctly, it should give you quiet heating and cooling. It’s expected for it to produce some noise when it’s turning on or running. But loud or odd sounds are frequently an indication that your heat pump needs pro repair.

Here are some of the most frequent heat pump noise complaints we receive calls about and what they indicate. When your heat pump is acting up or making odd sounds, our heating and cooling professionals are here to assist with the best heat pump repair in Cottonwood & Prescott.

1. Heat Pump Making a Humming Noise

Your heat pump uses electricity to heat and cool your home, so it’s normal for it to make some humming noises as it runs. But if those noises are annoying or your heat pump is making a humming noise inside, it’s typically due to the fact there’s an electrical problem. Sometimes this is because of a dilapidated piece, or it could be a broken fan motor. Whatever the trouble is, Connolly Electric & Mechanical can fix it.

2. Heat Pump Making Loud Noise

If your heat pump is making loud noises in cold weather, it may be due to going into defrost mode. You may hear a whooshing noise as your heat pump works to defrost itself and remove frost from its coils. This frost can accumulate as a result of the temperature and humidity levels. Defrost mode is totally normal, but if your heat pump is icing up a lot or totally frozen, you might be dealing with another situation. The fix may be as easy as getting a new air filter or as detailed as needing additional refrigerant. If you’ve added a new filter but your heat pump still isn’t working right, contact us at 928-251-4327.

3. Heat Pump Making a Clicking Noise

It’s typical for your heat pump to click after it starts. But if your heat pump is making a clicking noise during the full length of its heating or cooling cycle, call us at 928-251-4327. There could be an issue with your capacitor, which turns on the motor.

4. Heat Pump Making a Grinding Noise

Grinding, or metal-on-metal noises, are never great. They’re typically the result of a lack of routine heat pump maintenance, which keeps your unit clean and lubed. When parts get filthy or require lubrication, they can produce loud grinding noises. Usually, this sound indicates there’s trouble with your heat pump’s motor. We advise switching off your system to stop additional damage. Then, give us a call at 928-251-4327 for assistance.

5. Heat Pump Making a Banging Noise

If your heat pump is making a banging noise, we suggest shutting it down and calling our pros at 928-251-4327 for help. A component may be unsecured and cause more damage if you keep running your system.

6. Heat Pump Making a Hissing Noise

When your heat pump makes a loud hissing noise, it’s usually since it doesn’t have ample refrigerant. Refrigerant could be low or there might be a leak, which is an environmental risk. Both situations require the assistance of a certified technician, like one from Connolly Electric & Mechanical.

We know heat pump problems can be frustrating, but it’s our priority to make the repair process as quick as possible. That way, you can get back to your daily agenda rapidly.
