The Top 10 Noises That Cause Concern
Air conditioners can make a lot of noises, but these are some of the worst offenders when it comes to requiring repairs. Keep your ears peeled and make sure you call us if any of these sound familiar.
- Hissing. When gaseous refrigerant starts to leak out of your system, it can make a hissing noise. This is important to get fixed because your air conditioner relies on refrigerant to perform the cooling process. Without it, it’s just an oversized fan.
- Bubbling. The other end of the hissing noise is bubbling, which is the sound of oxygen bubbles forming in your liquid refrigerant line. This should be fixed quickly too.
- Shrieking. If your air conditioner is shrieking, there’s likely a serious component malfunction that can quickly lead to a system breakdown. Especially if it’s loud, we recommend shutting your system down ahead of time and calling for help.
- Grinding. A grinding sound can sometimes be attributed to the fan blades rubbing up against the housing when there’s been a misalignment or a malfunction.
- Buzzing. Buzzing can almost always be associated with an electrical problem. When wires fray or other components short, this can lead to a consistent buzzing noise.
- Constant clicking. Your system should only click once to start on or turn off. If it continuously clicks, this could be a sign that your system is in disrepair and something needs to be fixed or replaced.
- Squealing. A squealing noise can often come from a fan belt that’s been worn down or is in need of replacement.
- Rattling. If a small screw or component becomes loose, it can start to rattle when your system turns on. This needs to be repaired before it causes a worse problem.
- Clanging. Clanging can be attributed to larger components becoming loose or breaking apart.
- Nothing. Your system should at least make some kind of noise to show that it’s on, whether it’s the blowing of cool air or the gentle whir of the compressor. If it’s dead silent, then it’s broken down and should immediately be fixed.
