10 Types of AC Noises You Shouldn’t Ignore

The air conditioning system is designed to keep residential and commercial buildings indoors cool and comfortable in extreme summer temperatures. Additionally, air conditioning systems help keep indoors safe and healthy by maintaining the humidity levels and airflow.

However, if your AC system is interfering with your sleep and preventing a peaceful and calm environment, you should contact us for AC repair in Greenville, NC, so we can help determine what’s wrong with your AC system.

10 Types Of AC Noises That Every Homeowner Should Pay Attention To:

An AC system is supposed to work with minimal operational noise levels after it has spent around 5-6 years functioning in your home or business. However, if the noises become loud or strange, you should call us for air conditioning services in Greenville, NC, to inspect the AC system.

Here are ten different noises to listen for and their meanings, so you can try to fix the issue before calling a technician for repairs:

1. Screeching

If your AC system makes a high-pitched screeching noise, it represents an issue with the fan motor or blower belt. Sometimes, the blower belts expand and contract due to temperature fluctuation if you live in a high-humidity area. It can cause the AC system to make such noise.

However, it can also be due to a worn-out blower belt, or it may have slipped from its place. If this is the case, you will need to schedule a service with an AC replacement expert in Greenville, NC, to replace or repair the belt.

In modern AC systems, the blower belts are replaced with direct-drive motors that use a fan to draw air across the condenser coils. So, if you have recently purchased a new AC model and you are hearing this noise, there is likely a motor failure, or the fan bearings need to be replaced.

2. Banging

Banging sounds can have several meanings. It can indicate that something loose in the AC system is striking against the AC unit’s walls due to vibration while the AC is functioning.

However, it can also represent a worn-down compressor. If you hear this noise, switching off the system and contacting us for AC installation in Greenville, NC, is recommended to avoid further damage.

3. Hissing

A hissing noise is a sign that there is either a refrigerant or air leakage in the system. You should quickly shut down the system and cover the leakage area with duct tape until our air conditioning services experts in Greenville, NC, come to replace the pipe.

However, if you hear this noise from the duct system, air leakage could lead to uncomfortable and uneven temperatures in your residence. Additionally, it can cause the system to overwork, which is harmful to the compressor.

4. Buzzing

Buzzing noises are associated with electrical issues in the system. Electrical issues can impact your home and yourself as well. So, if you do not have any prior experience dealing with electrical issues, contact us and we’ll send an AC replacement expert in Greenville, NC, to inspect the connections.

It indicates an issue with the wiring of the blower motor, relay switch, condenser fan, or other components in the AC system assembly. The condition of the system is serious if you hear or see sparking from the circuit box or the unit.

5. Clicking

It’s typical to hear a single clicking sound when the AC system’s cooling cycle starts. But, a persistent clicking noise is an unfavorable indication, as it suggests that there may be a problem with the electrical wiring or thermostat preventing the AC system from turning on.

If you hear a banging noise, it implies that there is an issue with the compressor, and you’ll need to seek out an HVAC repair in Greenville, NC. On the other hand, if the clicking sound starts slowly and then speeds up over time, this could be an indication of an issue with the blower fan.

 

6. Gurgling Noise

A gurgling noise is an indication of an issue with the condensate drain. A clogged condensate drain needs to be cleaned to avoid water puddle formation. You can find the blockage by using the torchlight and cleaning it with a long metal brush or stick.

If you cannot find the blockage, call the air conditioning service experts in Greenville, NC, to clean the pipe.

7. Rattling

If you hear a rattling or clicking noise, it is a sign that a loose bolt or tiny component is moving inside the AC unit. Additionally, it can mean that the indoor or outdoor unit’s fan blades are out of order. If this is the case, call an AC replacement expert in Greenville, NC, to replace the fan and tighten all the bearings and bolts.

8. Humming

A low humming noise is a good sign that your AC system is operating perfectly. However, if you hear loud vibrational noises, a loose component is out of place.

9. Whistling

Whistling noises are an indication of poor return airflow. It can easily be resolved if you clean or replace the air filter. However, it can also be a sign of a refrigerant leakage, which can be harmful to your health. A leaky refrigerant line may produce a bubbling noise.

Experts recommend listening for these noises and quickly reaching out for air conditioning services in Greenville, NC, to fix the issue.

10. Squealing

Squealing is a sign of high internal pressure developing inside the system. The pressure builds inside the compressor, and there is a safety switch to shut down the situation if the pressure inside the system rises. However, if you haven’t called our AC repair in Greenville, NC, for annual maintenance, the safety switch may have worn down and stopped working,
