Despite its name, a heat pump is part of your heating and cooling system. Whether it’s winter or summer, the heat pump works by removing heat from the air. The difference between the two seasons is where the heat pump delivers the heated air. During the winter, the warm air is distributed through the vents and into the interior of your house. During the summer, the heated air is moved outside the home.

Heat pumps are designed for quiet, efficient operation, so you should not hear excessive noise when the HVAC equipment runs. The following covers five noises that homeowners in Niles and the surrounding areas may hear from their heat pumps. Hearing any one of them should prompt you to call A To Z Dependable Services for repair services.

1. Humming

Heat pumps are not completely silent, but you should be familiar with normal operating sounds. The heat pump will make a quiet humming sound, but it shouldn’t be any louder than your dishwasher. Loud humming from a heat pump is most often caused by a problem with the electrical components.

In these cases, it is best to leave repairs to a professional technician from A To Z Dependable Services. Hissing is a noise that sounds similar to humming from the heat pump. This is typically caused by air or refrigerant leaking out of a small hole. Diagnosing and repairing a hissing noise takes an in-depth understanding of heat pumps. You can schedule an appointment with A To Z Dependable Services to repair the pump.

2. Rattling

Rattling from your heat pump typically indicates that something is touching the fan, such as a branch, leaf or small object. The noise may also be caused by debris inside your ducts. Turn the unit off completely, and check around the fan for any debris. If there are no objects around the fan, the problem is likely in the ducts.

Cleaning the ducts is a labor-intensive project, so you should call A To Z Dependable Services to schedule an appointment with a technician. You should also replace your filters to prevent debris from getting inside the ducts.

3. Screeching

Screeching sounds from your heat pump usually mean that there is some type of metal-on-metal contact, and the most common source of screeching is the fan. The blades, housing or motor may be damaged.

You can try to fix the problem yourself by checking the fan components and tightening all of the screws on the mount. If you are not comfortable doing this or if the noise continues, a technician from A To Z Dependable Services should take a look at the unit.

4. Thumping

A thumping noise from a heat pump is normally caused by some kind of vibration inside the unit. Check all of the screws and bolts that mount the components and hold the pieces together. If everything looks good and the noise continues, you will need to have a technician perform any further repairs.

Not fixing the problem can cause significant damage to your heat pump and HVAC system, and you may end up replacing large components or the entire unit. Problems behind thumping and vibrations can also make your unit work harder, which shortens the lifetime of the equipment and increases utility costs.

5. Whistling or High-Pitched Noise

Whistling and high-pitched noises are often heard inside the home. The sound is caused by air rushing through a small opening, like when you whistle. The two most common reasons that technicians from A To Z Dependable Services find for whistling noises from a heat pump are blocked vents and dirty filters.

You can check your vents and replace the filters to see if that fixes the noise. If neither of these makes the noise stop, call us to schedule an appointment with one of our technicians. You can prevent whistling noises in the future by keeping items away from the vents and replacing your filters according to the recommended schedule on the packaging.
