Why Is My Heat Pump Making Loud Noises?
Heat pumps can be expected to make some noise. However, unusually loud noises point to a problem. If your system is reaching decibels impossible to ignore, you should turn it off to prevent further damages. Then give BlueAir a call at 512-257-8423 to schedule a repair visit. We’ll be able to quickly identify the problem and give you a fair and honest quote.
Because we like to help educate our customers, here are five heat pump noises to keep an ear out for:
1. “Bam! Bam! Bam!”––Metal Rapidly Hitting Metal
If you hear a metallic clang repeating in a cycle, there’s probably something going on with your condenser fan blade. What you’re hearing may be the sound of the blade hitting another hard object. Immediately turn off your heat pump’s power if you believe this to be the case. Under this type of stress, the fan will become bent or chipped. Once the machine is off, inspect the inside for any foreign objects, then give one of our technicians a call to repair or replace your fan blade if necessary.
2. “Sssss . . . ”––Hissing
There’s always a small chance a snake with unlimited lung power has inhabited your heat pump. However, the more likely possibility is you have a refrigerant leak. You’re hearing the sound of gas escaping. In this instance, you should contact one of our technicians to assess the leak and replenish the refrigerant supply.
3. “Reeeeeee . . . ”––Screeching/Squealing
Your heat pump should really use its “inside voice.” If you hear high-pitched screeching or squealing, there’s a good chance the motor is having trouble. Have a technician inspect it before it goes out completely.
4. “Hmmmm . . . ”––Loud, Low-Pitched Droning
A low-pitched hum is usually benign, unless it’s significantly louder than usual. You could think of this sound as the heat pump grumbling with hunger. Having a unit that is low on refrigerant can cause the compressor to be louder. Or, the humming might indicate that your compressor is on its last leg. If you hear a humming and the unit isn’t working, you may have a bad capacitor. You might be tempted to fix it yourself. However, keep your distance, and let a technician wrangle the beast.
5. “Clink! Clank!”––Rattling
This sound can be particularly annoying. It usually indicates a loose, detached, or poorly balanced part. This could be a motor mount that has become unfastened. Or it could be your blower wheel has been poorly aligned and is rattling against another component in the heat pump. Yet another possibility is worn-down compressor bearings. One of our technicians can remedy all of these problems through a quick tune-up or part replacement if necessary.
