5 Worrisome Heat Pump Noises in Conway, SC

You don’t expect loud noises from your Conway, SC, heat pump when you cool your home this spring. Unusual sounds typically indicate a malfunction and require professional repairs. Read on to learn more about some noises your heat pump may make and what those noises might mean.

1. Banging and Rattling

Loud banging, clanging, and rattling sounds may indicate a loose or damaged part inside your HVAC system. These parts rattle around and bang against other components when the heat pump runs, causing these loud noises. Loud banging and rattling sounds are a sign that you need immediate repairs.

2. Whistling

Whistling often indicates high pressure inside your heat pump, often due to restricted airflow. First, check to see if the air filter needs changing. Sometimes, a leak in the air ducts can also cause a whistling sound.

3. Squealing

A squealing heat pump may mean that the fan belt is loose or the bearings are dry. These noises indicate a malfunction that requires repairs, even though the system may still appear to operate properly.

4. Hissing or Gurgling

A hissing or gurgling sound coming from your heat pump may indicate low refrigerant, possibly due to a refrigerant leak. The gurgling noise comes from air mixed with the refrigerant when the reservoir is low. Refrigerant leaks are hazardous, so you should have a professional address them promptly.

5. Humming or Buzzing

Strange humming and buzzing sounds often indicate an electrical issue. These sounds might mean that your heat pump is trying to start, or they could indicate a faulty capacitor or loose wiring.
