Find Out Why Air Conditioning Systems Make Strange Noises

Modern air conditioners are built to operate with minimal noise. Some might still create some level of sounds that are part of their daily operation. In fact, a little noise isn’t something to worry about.

However, if your equipment is producing sounds that you never heard before, then that’s the time to investigate. It might be a symptom of a bigger problem. In this case, you need the best air conditioning service from your trusted A/C specialists.

Here are the strange noises and the reasons why they occur:

Clicking Sounds

Your A/C normally produces clicking sounds once the cooling cycle starts or ends. But if the sound becomes consistent throughout the operation, the culprit could be a faulty thermostat. The device could either need a repair or replacement.

Buzzing Sounds

Electrical issues and loose fan blades in the outdoor component are the main causes why air conditioners create buzzing sounds. Seldom, a leaking refrigerant, dirty condenser coil, damaged outdoor fan motor, or lose A/C component is the culprit of the problem. Call for the best air conditioning service to address the issue.

Humming Sounds

Your A/C might have a defective contactor relay switch if it’s producing a humming sound. If the switch is faulty, your equipment might fail to turn on. The sound can also be created when the fan motor is problematic.

Screeching Sounds

This is among the most distinct sounds any A/C can create. Most probably, the problem roots from the condenser’s fan motor, which removes the heat from the refrigerant. Therefore, the cooling process can be hampered if the fan is problematic.

A damaged blower fan, bad fan belt, or faulty fan motor bearing is another culprit why your system creates screeching noises. It’s recommended to bring in an expert for the best air conditioning service.

Whistling Sounds

A refrigerant leak is a common issue why whistling or high-pitched noises are heard from your A/C. Another one to blame is the high pressure in the compressor. Either of these problems is serious. Turn off your air conditioning system and call your trusted A/C contractor for an immediate solution.

Clanking Sounds

Clanking sounds are produced when a loose metal component hits another metal part inside the A/C. Leaving this problem unfixed for an extended period can create further damage to your equipment. You need to repair or replace the unbalanced or loose component to restore your system’s function. Call the experts for the best air conditioning service.

Rattling Sounds

A rattling noise is produced when there is loose debris in the outdoor component. Debris like leaves, twigs, and clumps of dirt can fell inside the component and cause a rattling sound during theoperation. Open the condenser and clean it to remove the debris.

But if you do all the cleaning and nothing works, the problem might be coming from the electrical contractor. This requires a professional technician for the fix.

Banging Sounds

When the compressor runs faulty or the indoor blower is not balanced, a banging sound is typically produced. It is common in old air conditioning systems with loose or unfasten parts or broken piston pin, connecting rod, or crankshaft. Schedule an appointment with your trusted technician for the best air conditioning service.
