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

October 13, 2020

When your heat pump is running like it should, it should give you quiet heating and cooling. It’s common for it to produce some noise when it’s starting or running. But loud or odd sounds are often a symptom that your heat pump needs pro repair.

Here are a few of the most frequent heat pump noise complaints we get 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 Tucson.

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 disruptive or your heat pump is making a humming noise inside, it’s frequently because there’s an electrical issue. Sometimes this is due to a worn-out part, or it could be an inoperable fan motor. Whatever the problem is, A&M Heating & Cooling LLC can repair it.

2. Heat Pump Making Loud Noise

If your heat pump is making loud noises in cold weather, it can be because it’s switching to 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 form due to the temperature and humidity levels. Defrost mode is completely normal, but if your heat pump is icing up a lot or totally frozen, there could be another issue. The solution can be as fast as installing a new air filter or as detailed as needing additional refrigerant. If you’ve replaced the filter but your heat pump still isn’t running right, reach us at 520-200-1048.

3. Heat Pump Making a Clicking Noise

It’s common for your heat pump to click once it turns on. But if your heat pump is making a clicking noise during the full length of its heating or cooling cycle, call us at 520-200-1048. There may be trouble 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 consequence of frequent heat pump maintenance, which keeps your heat pump clean and lubricated. When components get grubby or need lubrication, they can produce loud grinding noises. Often, this sound indicates there’s a problem with your heat pump’s motor. We advise shutting down your system to stop further damage. Then, give us a call at 520-200-1048 for assistance.

5. Heat Pump Making a Banging Noise

If your heat pump is making a banging noise, we advise turning it off and reaching our professionals at 520-200-1048 for support. A part may be unsecured and cause more damage if you keep operating your unit.

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 enough refrigerant. Refrigerant may be low or there might be a leak, which is an environmental danger. Both situations require the support of a certified technician, including one from A&M Heating & Cooling LLC.

We realize heat pump problems can be irritating, but it’s our aim to make the repair process as simple as possible. That way, you can get back to your daily schedule quickly. When you need heat pump repair in Tucson, call the A&M Heating & Cooling LLC pros at 520-200-1048 for fast, friendly service you can trust.
