If you are hearing strange, metallic, grinding noises coming from your AC, it can be annoying and worrisome. Here are some reasons that could explain why your AC is making those unfamiliar sounds.
That metallic grinding noise may be from your compressor being worn out, which means that the compressor needs to be replaced entirely. The compressor is the core of your AC, making sure that the refrigerant gas is being circulated for heat exchange in the coils of the unit. The loud, grinding AC noise could be caused by your pistons, which compress your refrigerant gas.
Your best bet is to shut off your AC, and then call a professional. A grinding noise is not something that can wait and can lead to serious damages to your air conditioning unit if left without repair.
Your grinding noises could also result from your blower fan belts being loose or damaged. The noise is produced when the belt is loose as it rubs up against all the other parts within the AC. This can lead to other major damages, since your belt can damage the other parts it comes in contact with and ruin your AC’s ability to function properly.
Belt repairs can be a small fix or something major, depending on how early you catch the problem. It is not something you can repair on your own, so you will need to call a technician for your AC repair.
A hissing noise is also something to be worried about. The problem may be a refrigerant leak or in the AC’s internal valves. This needs to be inspected as soon as you notice it to prevent the leak from persisting and valves being further damaged. Refrigerant leaks can be harmful to your health. Your compressor pressure being too high can also cause a hissing or screaming noise. In both cases, be sure to shut off your AC until a professional can take a look at the problem.
If you are experiencing any kind of noises coming from your AC, from grinding to hissing and screaming, it’s important to call a trusted professional. Call the team over at Go Green Heating and Cooling for an AC inspection today.

5-star service all around from the initial consultation to the final install. Thank you for a flawless experience, Brandon Acosta!
After receiving a ridiculously high quote from the HVAC company sent out by our home warranty, my husband wanted a second opinion. Our technician Mike was thorough and honest about what needed repair. Not only was the diagnosis much simpler, so was the price. Mike got the repair done quickly and was very professional. We’ll definitely be calling Go Green again.
