7 Sounds from Your Air Conditioner You Shouldn’t Ignore

March 11, 2022

We all enjoy the low humming noise of an air conditioner, mainly because it signifies warmer weather and the privilege of cool air on a hot, humid day.

An air conditioner is comprised of complex components and parts that all depend on each other to work. The age of the unit and the constant usage both play a role in how well the air conditioner works.

If you hear strange noises coming from your AC unit, it may mean it’s time to call for air conditioning repair services in East York.

Gurgling/Bubbling Sounds

One of the obvious air conditioning warning sounds is a bubbling or a gurgling noise. This can be due to a refrigerant leak. Refrigerant can cause serious health concerns such as nausea, vomiting, and respiratory issues if a leak in the refrigerant line is not attended to. It is important to call a repair service, even if you don’t experience any of the abovementioned symptoms, as a drop-in refrigerant can damage your air conditioner.

Running Water Sounds

Hearing running water? This noise of water dripping will be different than a bubbling sound. In most cases, this might be because the drain line that takes the water from the air handler to the outside of the house is split or broken. This too can cause severe damage to the unit as well as the surrounding area and requires repair service from a professional technician.

Screeching Sounds

It’s normal for an air conditioner to make a low humming sound. It’s not normal to have to cover your ears from the sound of screeching! Like a constant screeching noise in a motor vehicle, it could signify that the belt or fan in the air conditioner is beginning to wear down. If this noise stops once the unit is running at full capacity, the issue may lie within the compressor itself and will need to be replaced. Either way, it’s best to call a professional repair service.

Heavy Banging Sound

If your air conditioning unit starts to produce loud banging noises, quickly shut off the power to the unit. The compressor within the air conditioner may be to blame for the banging noise. If allowed to continue to bang and shake, you may need to replace the entire unit. The unit depends on this component to work. Any sort of clanging requires a service call.

Buzzing Sounds

Air conditioners are expected to hum, to a point. If the humming turns to a buzzing sound, replicating that of a bee, expect to make a call to the repair company. It may be because of a frozen line that needs to be thawed out, the fan blades have become unbalanced, or there is a blockage. Or it may be more serious such as frayed electrical wiring or the fan motor is beginning to wear out.

Rattling Sounds

Aside from being annoying, a rattling noise can be a sign of wear and tear of one or more components. A clattering or rattling sound may also indicate the inside fan has moved out of alignment. A rattling noise could also indicate that another component has become loose and is freely moving around inside the unit.

Whistling Sounds

An extremely loud humming noise that at times sounds like a tea kettle whistling may indicate a loose seal within the air conditioner. Other issues can be a loose fan belt, a bearing that has become worn, or a buildup of internal pressure. Whistling can also be attributed to the motor needing to be lubricated or be the first indicator that the compressor is failing. Whistling is a warning sign to have service performed on the unit.
