A noisier than usual air conditioner is typically a sign of trouble that can indicate serious problems within the system. If you begin to hear strange sounds coming from the AC or ventilation, it’s time to call your local HVAC contractor to find out what’s happening. Below are several noises your AC shouldn’t make but may alert you of a problem.

Call an HVAC Contractor If You Hear These 5 Noises From Your AC

1. Grinding

HVAC ContractorSharp grinding noises typically are the result of two or more pieces of metal in contact. This can happen when a bearing has deteriorated and may lead to other components being disrupted or failing if not repaired.

2. Squeaking

When bearing components in the motor need to be lubricated, a squeaking noise can happen. Squeaking is usually a minor problem that can snowball into something major if it’s not handled quickly.

3. Hissing

A hissing sound may be the result of a refrigerant leak and should be inspected by an HVAC contractor as soon as the noise is detected. Refrigerant leaks will require repairs to be made immediately.

4. Scraping

If you have a mini-split system, the indoor and outdoor systems have motors and fans that contain parts which can be become dislocated.  The unhinged parts can scrape against the other components and create loud noises.

5. Rattling

The outdoor AC unit can collect debris such as leaves, dirt, rocks, twigs, and even small wildlife like lizards and snakes. If you hear rattling noises, there may be something stuck inside the unit.
