When equipment becomes noisy, it’s normal to assume that something is wrong. However, you may hear strange noises from your heat pump even if it’s in top condition. This problem tends to get worse during the winter months.

Some Sounds Should Be Expected

Before you become too alarmed, we should mention your heat pump’s defrosting mode. Since heat pumps have both heating and cooling capabilities, they utilize refrigerant, and there’s a valve that reverses the flow between these cycles. Sometimes, the equipment can frost up. When it does, it will automatically go into its defrost function. The fan will cease operation for the duration, and the process can be rather loud. This can last up to 10 minutes, but it’s quite normal.

You may also hear a distinct buzzing coming from the reversing valve’s solenoid coil. When your unit is starting up or shutting down, you might hear clicking and tapping sounds.

If it has a dirty or damaged motor, it will likely shriek louder than usual. Therefore, it’s best to let a professional technician fine-tune your unit regularly. Debris on top of wear and tear can shorten the lifespan of your heat pump.

Time to Take Action

If you hear a noise that sounds like metal hitting metal, it could be fan blades striking something. They could be colliding with a buildup of ice. Otherwise, they might be hitting some loose internal parts such as tubing. In either case, the blades could be bent and damaged. You should shut off the heating system immediately and call in a technician.
