Noisy air conditioners aren’t only a nuisance, but they can be signs of something problematic lurking deep within your air conditioning system. While not all noises are created equal, these are the four sounds your air conditioning system should never make:
If your air conditioning system is making a buzzing sound, there may be an electrical issue. A buzzing noise is almost always indicative of an issue with the condenser fan motor, the contractor relay switch or a sign of loose wiring. Because electrical issues may be dangerous, be sure to turn off your air conditioner right away and call a professional.
A hissing sound emitting from your air conditioning system may be indicative of a refrigerant leak from either a line or coil. It’s important to get this issue addressed right away, as refrigerant is both expensive and necessary in order to cool your home. Refrigerant leaks can be dangerous too, so make sure you enlist the help of a professional to diagnose and assess any issues.
A very loud and high-pitched squealing noise is usually indicative of high internal pressure. High internal pressure can build up inside of the air conditioner’s compressor. Although compressors usually have a sensor that will signal the air conditioner to shut off if the pressure gets too high, if it doesn’t, the pressure could rise to a dangerous level. If your air conditioner is making this noise, be sure to shut your AC off right away.
A rattling noise and any other thumping, clanking or banging sound is usually indicative of an issue with the assembly motor or blower. Rattling may mean that a small component of the air conditioning system has come loose and is flying about the unit. If this is the case, it should be an easy fix. Simply shut off your air conditioning system and check to see if anything has come loose, broken or been disconnected.
