As the temperature outside grows hotter with the changing season, you’re probably looking to your air conditioner for salvation. Today’s air conditioning units are quieter than ever. When your AC unit starts making unusual noises, it’s best to schedule professional AC maintenance before it becomes a costly problem.

If you’re experiencing weird air conditioning noise, it could simply require a tune-up. Before problems arise, get reliable AC service in Orlando by Temperature Pro. However, certain noises can be indicative of more severe issues. We’ve put together a list of common AC noise issues to help pinpoint your problem early and save you from costly repairs.

1.    Your AC is Rattling

Your AC unit could be making a rattling noise for a few reasons. The first thing to look for is loose bolts or screws. The AC unit vibrates and, over time, may cause the hardware to come loose. A loose fan may also be the culprit.

Another cause for rattling is debris inside the unit. Leaves or twigs will sometimes find their way into your air conditioner. Handle this issue as soon as possible to prevent buildup, which can burn out your AC unit. Regularly replacing your interior air filter will help prevent this situation.

2.    Your AC is Banging or Clanking

Is your air conditioning noise issue making a banging or clanking sound? Loud noises like this usually happen because of a broken or loose part, like the compressor, fan, or blower.

If the compressor has become loose or the components inside have worn out, it will likely require replacement. If a blower or fan has come out of balance, the blades could be hitting other parts within the AC unit.

Luckily, both of these issues are quick and easy for an HVAC technician to fix. Remedy these issues quickly, or they will become worse and more costly.

3.    Your AC is Clicking

If your air conditioning unit is constantly clicking, this could be a sign of an electrical issue. It is normal for AC units to click when they first turn on, but continuous clicking may indicate an issue with the thermostat or control module. Take electrical issues in your AC unit seriously. Faulty electrical parts may burn out major components in the AC unit or start a fire.

4.    Your AC is Buzzing

There are several reasons your AC may be buzzing:

  • Leaves or other debris inside the unit
  • Loose fan blades
  • Dirty condenser coils
  • Dirty air filter
  • Refrigerant leak

If the AC unit is running and not producing cold air, a refrigerant leak is likely. Some of these issues are minor, but others, like refrigerant leaks, can be dangerous. Call an HVAC repair company as soon as possible to diagnose and repair the problem.

Weird air conditioning noise is something to look out for so that minor problems don’t become major. It is important to know the signs when an AC unit needs servicing.
