Noisy A/C? Yours May Need Help

Loud A/C?

Do you have a noisy A/C that is worrying you? Noise coming from your A/C should not be ignored. It is a sure sign that something is loose or starting to malfunction. Waiting too long can lead to an expensive repair. There are some things you can check before calling for service.

  • Loose fasteners – Start by looking for loose screws on the panels or covers. Vibration in the unit can cause fasteners to become loose over time. Listen for a rattling sound when the system is operating. You may hear the noise throughout your home. Take the time to track down the sound to the actual location of the problem.
  • Noisy fan – Debris on the fan blades can cause vibration in the fan and noise in the system. If the fan is accessible, clean off the blades, being very careful not to bend them. This can cause the fan to become unbalanced and may result in a costly repair. If the blade is loose, it can be tightened with a screwdriver or wrench. If it is obvious that the blades are damaged, there may be another problem in the unit, and a certified technician should diagnose the problem.
  • Dirty coil fins – The coil fins may have become clogged with dirt. A vacuum cleaner with brush attachment can be used to clean the coil fins of debris.
  • Lubrication of the motor – The HVAC system motor needs regular lubrication. This is better left to a qualified technician who will know the correct oil to use for the unit in your home.
