Humming, Whooshing and Clicking: What 6 Typical Heat Pump Noises Mean

October 13, 2020

When your heat pump is running correctly, it should provide you with quiet heating and cooling. It’s common for it to create some noise when it’s starting or operating. But loud or odd sounds are frequently an indication that your heat pump needs specialized repair.

Here are a couple of the most common heat pump noise complaints we receive calls about and what they mean. When your heat pump isn’t functioning properly or making weird sounds, our heating and cooling specialists are here to support you with the best heat pump repair in Mobile.

1. Heat Pump Making a Humming Noise

Your heat pump consumes electricity to heat and cool your home, so it’s expected for it to make some humming noises as it works. But if those noises are loud or your heat pump is making a humming noise inside, it’s often because there’s an electrical situation. Sometimes this is because of a dilapidated piece, or it could be a nonfunctional fan motor. Whatever the issue is, Farnell Heating & Air Conditioning Inc can help.

2. Heat Pump Making Loud Noise

If your heat pump is making loud noises in cold weather, it could be the result of switching to defrost mode. You may hear a whooshing noise as your system works to defrost itself and get rid of frost from its coils. This frost can accumulate due to the temperature and humidity levels. Defrost mode is totally normal, but if your heat pump is icing up often or frozen solid, there could be another issue. The fix could be as easy as installing a new air filter or as complicated as needing additional refrigerant. If you’ve replaced the filter but your heat pump still isn’t operating right, give us a call at 251-471-2674.

3. Heat Pump Making a Clicking Noise

It’s typical for your heat pump to click once it switches on. But if your heat pump is making a clicking noise during the full length of its heating or cooling cycle, contact us at 251-471-2674. There may be an issue with your capacitor, which switches on the motor.

4. Heat Pump Making a Grinding Noise

Grinding, or metal-on-metal noises, are never good. They’re typically what happens when you forget about routine heat pump maintenance, which keeps your unit clean and greased. When parts get filthy or require lubrication, they can make loud grinding noises. Typically, this sound means there’s an issue with your heat pump’s motor. We suggest turning your system off right away to stop additional damage. Then, give us a call at 251-471-2674 for support.

5. Heat Pump Making a Banging Noise

If your heat pump is making a banging noise, we suggest turning it off and contacting our professionals at 251-471-2674 for support. A component could be loose and result in added damage if you keep running your heat pump.

6. Heat Pump Making a Hissing Noise

When your heat pump makes a loud hissing noise, it’s often since it doesn’t have ample refrigerant. Refrigerant might be low or there might be a leak, which is an environmental hazard. Both situations require the support of a certified professional, including one from Farnell Heating & Air Conditioning Inc.

We understand heat pump troubles can be frustrating, but it’s our goal to make the repair process as quick as possible. That way, you can return your daily agenda quickly.
