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

October 13, 2020

When your heat pump is operating like it should, it should deliver peaceful heating and cooling. It’s common for it to create some noise when it’s turning on or operating. But loud or odd disruptions are often 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 is acting up or making strange sounds, our heating and cooling specialists are here to support you with the best heat pump repair in Tucson.

1. Heat Pump Making a Humming Noise

Your heat pump relies on electricity to heat and cool your home, so it’s common for it to make some humming noises as it operates. But if those noises are loud or your heat pump is making a humming noise inside, it’s frequently due to the fact there’s an electrical issue. Sometimes this is caused by a dying component, or it could be an inoperable fan motor. Whatever the problem is, Ambient Air can help.

2. Heat Pump Making Loud Noise

If your heat pump is making loud noises in cold weather, it may be because it’s going into defrost mode. You could hear a whooshing noise as your unit works to defrost itself and melt frost from its coils. This frost can build up because of the temperature and humidity levels. Defrost mode is totally normal, but if your heat pump is icing up frequently or frozen solid, there could be another issue. The solution could be as fast as installing a new air filter or as complicated as needing extra refrigerant. If you’ve installed a new filter but your heat pump still isn’t operating correctly, give us a call at 520-357-4912.

3. Heat Pump Making a Clicking Noise

It’s common for your heat pump to click once 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 520-357-4912. There may be something wrong with your capacitor, which starts the motor.

4. Heat Pump Making a Grinding Noise

Grinding, or metal-on-metal noises, are never great. They’re typically the consequence of regular heat pump maintenance, which keeps your unit clean and greased. When pieces get filthy or need lubrication, they can produce loud grinding noises. Typically, this sound is signaling there’s a problem with your heat pump’s motor. We recommend shutting down your system to avoid more damage. Then, contact us at 520-357-4912 for assistance.

5. Heat Pump Making a Banging Noise

If your heat pump is making a banging noise, we recommend turning it off and reaching us at 520-357-4912 for help. A part may be unsecured and lead to more damage if you keep using your heat pump.

6. Heat Pump Making a Hissing Noise

When your heat pump makes a loud hissing noise, it’s often due to the fact it doesn’t have ample refrigerant. Refrigerant might be low or there might be a leak, which is an environmental danger. Both situations require the assistance of a certified pro, including one from Ambient Air.

We know heat pump troubles can be frustrating, but it’s our aim to make the repair process as simple as possible. That way, you can resume your daily agenda rapidly. When you need heat pump repair in Tucson, call the Ambient Air pros at 520-357-4912 for quick, friendly service you can rely on.
