8 HVAC Noises You Shouldn’t Ignore

8 Noises you shouldn’t ignore.

Hearing strange noises coming from your HVAC? You may have grown used to the quiet hum that your unit produces, but it’s crucial to pay attention to any new, uncomfortable noises or sounds. Of course, not all noises indicate that you’re facing a crisis, but the majority of HVAC noises indicate that it’s time for maintenance or repair.

Here are some examples of those sounds and their possible sources, as well as some suggestions for putting them to rest.

BANGING, THUMPING, & RATTLING

These noises are usually caused by something coming loose in the motor or blower. If the banging becomes more pronounced, it’s likely that whatever was loose has now broken off.

GRINDING

This could indicate that the compressor is malfunctioning. The pistons can make this noise as the device starts to fail.

HISSING

If your unit hisses, especially while it isn’t running, it could be due to a leaking refrigerant line, an internal valve leak, or an excessively high compressor pressure.

BUZZING

This could indicate a number of issues, including loose parts, debris, a loose fan motor, the need to replace the air filter, or a refrigerant leak.

CLICKING

If your device clicks frequently, or more than at startup and shutdown, it could indicate a problem with the electrical control system. A faulty relay or a thermostat issue could be the source of the clicking.

HUMMING OR VIBRATING

This could indicate that the motor is out of balance or that there are loose parts. The louder the noise, the more urgent it is to have it looked at. Humming could indicate a malfunctioning motor or a strained compressor.

SQUEALING OR SCREECHING

This could be an indication of a failing component, such as a motor bearing trouble or a broken belt. If your belt is damaged, it may break, causing your blower to come to a grinding halt. This could result in more damage, therefore it’s critical to have it looked out before the belt snaps.

NEW NOISES

If your unit is generally silent but suddenly begins to make noises, you should contact an specialist immediately.


MAINTENANCE

The importance of keeping your system and equipment in good working order cannot be overstated. It’s critical to ensure that the complicated equipment that feeds your heating, ventilation, and air conditioning is running at peak efficiency.

This can have disastrous consequences, such as hospitalization and death. To avoid incidents like these, you must ensure that all of the components are in proper functioning condition.
