Noises You Should Never Hear From Your Home’s AC

Call My Father’s Mechanical right away if you hear strange noises coming from the air conditioner. Before you give us a call, however, it’s important that you turn the unit off immediately to avoid further damage. We are going to list the strange noises an air conditioner can make below and the causes for these noises. We can repair the problem or replace your air conditioner.

Banging

If your air conditioner is reaching the end of its life, it’s possible that the compressor is the reason why you hear banging noises. Banging or rattling noises are a sign that the internal mechanisms inside the compressor have loosened and are moving when the air conditioner is running.

Screeching

The air conditioner will screech if the fan in the outdoor condenser unit is malfunctioning. There may also be a problem with the blower motor or fan inside your home. Another thing that will cause the air conditioner to screech is a compressor motor that is broken.

Buzzing

It’s critical that you turn off the air conditioner right away if it is buzzing. This is a sign that the fan blades in the condenser unit are unbalanced or loose. Loose components inside the AC unit can also make a buzzing noise as can dirty condenser coils.

Rattling

If it has been a while since you have had your air conditioner service, it’s possible that dirt and leaves have made their way inside the unit. When the air conditioner turns on, the dirt and leaves make rattling noises. The electrical contractor can also rattle if it is damaged.

Clicking

Your thermostat will click once when the air conditioner turns on and click once when it turns off. If you hear continual clicking, there is a problem with the thermostat and it needs to be replaced.

Hissing

Hissing noises that occur while the air conditioner is running are a sign that you have holes in the air ducting. They can also be an indication that your air filter is not the right size for your HVAC unit.

Bubbling

Finally, if the air conditioner’s drainage pipe is blocked or otherwise damaged, the water may build up inside of the unit and you will hear bubbling when the air conditioner is running.
