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

October 13, 2020

When your heat pump is operating properly, it should give you peaceful heating and cooling. It’s normal for it to make some noise when it’s starting or working. But loud or odd disruptions are frequently a sign that your heat pump needs specialized repair.

Here are some of the most common heat pump noise complaints we have calls about and what they indicate. When your heat pump isn’t working right or making strange sounds, our heating and cooling specialists are here to help with the best heat pump repair in Los Angeles.

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 runs. But if those noises are disruptive or your heat pump is making a humming noise inside, it’s often due to the fact there’s an electrical situation. Sometimes this is because of a dying piece, or it could be an inoperable fan motor. Whatever the problem is, AZ Air Conditioning and Heating can repair it.

2. Heat Pump Making Loud Noise

If your heat pump is making loud noises in cold weather, it may be due to moving into defrost mode. You could hear a whooshing noise as your system works to defrost itself and remove frost from its coils. This frost can form due to the temperature and humidity levels. Defrost mode is entirely normal, but if your heat pump is icing up often or totally frozen, there could be another issue. The solution could be as fast as replacing the air filter or as detailed as needing more refrigerant. If you’ve replaced the filter but your heat pump still isn’t running properly, give us a call at 800-296-5088.

3. Heat Pump Making a Clicking Noise

It’s typical for your heat pump to click when it turns on. But if your heat pump is making a clicking noise all through its heating or cooling cycle, call us at 800-296-5088. There may be trouble with your capacitor, which starts the motor.

4. Heat Pump Making a Grinding Noise

Grinding, or metal-on-metal noises, are never positive. They’re often what happens when you forget about regular heat pump maintenance, which keeps your unit clean and lubed. When pieces get grubby or have to have lubrication, they can make loud grinding noises. Usually, this sound is signaling there’s a problem with your heat pump’s motor. We recommend turning your system off right away to stop more damage. Then, contact us at 800-296-5088 for support.

5. Heat Pump Making a Banging Noise

If your heat pump is making a banging noise, we recommend turning it off and calling our professionals at 800-296-5088 for support. A piece may be loose and result in more damage if you keep using your system.

6. Heat Pump Making a Hissing Noise

When your heat pump makes a loud hissing noise, it’s often because it doesn’t have ample refrigerant. Refrigerant may be low or there could be a leak, which is an environmental hazard. Both situations require the support of a certified pro, such as one from AZ Air Conditioning and Heating.

We understand heat pump issues can be irritating, but it’s our goal to make the repair process as simple as possible. That way, you can return your normal agenda fast.
