Today’s manufacturers of air conditioning systems make a special effort to design ACs that operate with a minimum amount of noise. Even the air conditioners made over a decade ago run with only a minor humming sound when the compressor comes on, and modern high efficiency systems work at almost a whisper.
So when an air conditioner does start to create a lot of noise, it’s something you’ll notice. But does all this racket mean that the AC is done and needs a replacement? Or is it a repair issue?
First, consider the age of the system
If you have an air conditioner that is more than 15 or 20 years old, it’s already past its prime and ready to be replaced. Extremely noisy operation at this point is just the best way the air conditioner has to remind you that it’s time to arrange for a new system installation.
Exactly what kind of sounds are you hearing?
If you don’t have an extremely old AC, analyze the sounds that it’s making. This will help you better understand what’s going on. If you’re only hearing a single loud noise, such as rattling or grinding, you’re probably looking at a repair. Mechanical grinding and shrieking sounds often come from motors that are suffering from wear and tear and loss of lubrication. The motor may need a replacement, but the whole system probably won’t. Rattling might be from a loose part, such as bolts and fasteners—or it could come from the compressor, which will need attention right away from professionals.
To be certain, contact HVAC technicians
The best people to make the call about whether your air conditioner needs repairs or a replacement are HVAC professionals. Only a trained technician can trace the sounds to their roots and then determine the best course of action. Sometimes it will be a repair, and other times the most cost-effective option is putting in a new system. (In general, any time a repair would cost half of the price of replacing the AC, replacement is the better choice.)
