Watch Out for These Common Air Conditioner Problems

There is no worse time to experience air conditioner problems than in the summertime. With warmer weather right around the corner, it’s important to remember that the heat of summer truly tests the operation and working condition of cooling systems. Avoiding small problems now could result in a system failure when you need your air conditioner the most. To prevent this, keep reading below for common air conditioner problems you should watch out for.

Banging Noise

If you notice banging, clanging, or the sound of metal-on-metal when your air conditioner is on, this is not a good sign. It’s typically indicative of a damaged unit. Usually, this kind of noise means that your fan blades have become bent or are coming loose. Eventually, this will cause damage to other parts of your air conditioning system, and can result in costly emergency repairs later on.

Screeching Noise

Also described as a squeaking or shrieking sound, this is usually a sign of a worn out motor, and is probably originating from your air conditioner cabinet. If you have not had your system maintained on a regular basis, then your motor has likely not been lubricated recently. The problem with this is that your motor accumulates dust and debris overtime, which negatively impacts its functionality. You should not only call an HVAC professional for repairs, but now is a good time to schedule a maintenance appointment as well.


Whether a leak has developed from your refrigerant line or your ductwork, this is not a problem to be ignored. Some people assume that an occasional refrigerant leak is normal, but this could not be further from the truth. This kind of leak can cause ice to build up on the coils and eventually will damage your compressor, preventing it from cooling. A leaky duct is also a problem: it releases airborne contaminants into your home and decreases your indoor air quality. Not only that, but it doesn’t allow your AC to work efficiently, and costs you unnecessary money as a result.
