Why Is My A/C Making Weird Noises?

Having a home air conditioning unit can help to keep your family cool and comfortable during those hot summer days. While you may do your yearly maintenance tasks and change your HVAC filter regularly, you may still experience problems with your HVAC system. When your air conditioning unit develops a weird noise, it's best to get it fixed now as the HVAC repairs will get costlier the longer you wait to call in an HVAC professional.

1. Whirring

One very odd noise that your air conditioning unit may make is a whirring noise. This is a clear indication that your HVAC system has a problem with one of its mechanical components. Some common culprits of this noise include bad bearings, a faulty fan, or a failing blower fan motor. It's advisable to shut off and call in an HVAC professional to help.

2. Pulsing

When your air conditioning system is running, you should hear a low pulsing noise. However, if that pulsing noise from your air conditioning unit gets louder, it's an indication that a component of your HVAC system is loose. Some common culprits of this noise include loose fan blades, panels, or even a fan motor. You should shut off your air conditioning unit and contact an HVAC professional for help with this noise.

3. Screaming

A very annoying noise that your air conditioning system may make is a high-pitched scream. As soon as you hear this noise, it's best to turn off your air conditioning unit. Immediately call in an HVAC professional to assess if your refrigerant line is leaking. Refrigerant can be dangerous to the health of your family, so you should no longer run your HVAC system until it's evaluated by an HVAC professional.

4. Rattling

Another commonly experienced noise of a faulty air conditioning system is a rattling noise. This unwelcomed noise can indicate a couple of problems with your HVAC system. These include loose screws, dirty condenser coils, or even a clog in your air conditioning system. You may want to contact an HVAC professional to identify the cause of this noise and remedy the problem with your HVAC system before it gets worse.

5. Humming

If you hear a constant humming noise coming from your air conditioning system, it's likely that there's a loose component. The loose component or piping will vibrate the air conditioning system and cause the humming noise to occur. The looser the component gets, the louder the noise will be. It's best to tighten the loose component in your air conditioning system as soon as possible. If you can't find the loose air conditioning component, it's time to contact an HVAC professional to help with the noise.
