What’s Causing My AC to Make So Much Noise in Prospect, KY?

While it’s perfectly normal to hear some slight humming or whirring coming from your AC, any noises that are louder than those almost always mean trouble. Here’s what homeowners in Prospect, KY should know about the weird sounds from their systems that indicate an AC repair is needed.

Hissing or Gurgling

These noises mean that your AC has a refrigerant leak. When holes form in the refrigerant lines, allowing the liquid to escape, it almost always emits a hissing noise. Once air displaces the lost gaseous refrigerant, bubbles will form, which creates gurgling noises.

You should also remember that refrigerant smells vaguely sweet. If you suspect that your AC is leaking refrigerant, you should evacuate your home and immediately request professional assistance. Since refrigerant is highly toxic, do not attempt to handle it on your own.

Rattling

Rattling noises typically suggest that some sort of small debris has found its way into your AC. Another possible explanation for this sound may be that one of the system’s fans has come loose, causing the blades to repeatedly strike some other part of your AC. Whatever the ultimate explanation, you will need HVAC maintenance services to make it go away.

Clicking

Under most circumstances, it is perfectly normal for your AC to temporarily emit a clicking noise. You should hear this when the system turns on after a period of inactivity whether it’s because a new cooling cycle has begun or because you’ve turned the system on for the first time. However, this noise should not last for long.

If it continues for longer than it should, then your system might have loose fan blades, a faulty capacitor, bad electrical wiring or some other issue. Trained technicians should investigate and find the source of the problem.

As a rule of thumb, a noisy AC is probably a damaged AC. To deal with any AC-related racket in Prospect, KY, call Birkhead Co. and ask for our AC repair services.
