All heat pumps make some noises as part of their normal operation. They might hum when electricity moves through them or click when a cycle begins and ends. However, if your heat pump makes any of the noises below, call for HVAC service in Bronte, TX.
1. Hissing
A refrigerant leak causes heat pumps to make hissing noises. The sound happens as the refrigerant escapes and it changes from high-pressure liquid status to a lower-pressure gas. Refrigerant leaks need immediate attention because they won’t provide efficient heating or cooling and can damage the system.
2. Gurgling
Hindered refrigerant movement through the system usually causes gurgling or bubbling sounds. Low refrigerant levels can also cause these sounds when there is air in the refrigerant line. Usually, the hissing sound mentioned above accompanies the gurgling sound.
3. Rattling
Never ignore rattling sounds while the heat pump operates because it could indicate loose or broken parts. If you hear rattling from the outdoor condenser part of the heat pump system, check it for leaves, sticks, rocks or other pieces of debris.
4. Thumping
Thumping or knocking sounds might indicate an unbalanced fan or motor. You don’t want to operate the heat pump when it makes these noises because it could cause further damage. Instead, have a professional inspect the system and make any necessary repairs.
5. Screeching
Faulty motor bearing or a worn fan motor belt can cause annoying screeching sounds. The moment you hear this sound, turn off the heat pump and call an HVAC technician to replace the belt or bearings. Continuing to operate the unit while it makes this sound can lead to further, more expensive damage to the unit.
