Understanding Air Conditioner Noises

Thanks to advanced technology, today’s air conditioners operate much more quietly than their predecessors. This results in a more calming environment in your home during the day and a more peaceful one at night. But if your air conditioner starts making unusual noises, this could be a sign that it’s in need of repairs.

In this article, HVAC repair expert Albert Air Inc. discusses some of the most common air conditioner noises and their possible causes.

Banging

Banging is often the result of a loose or broken part inside the air conditioner’s compressor. Typically it will be a crankshaft, connecting rod or piston pin. Sometimes it could also be an imbalanced indoor blower. It’s best to consult with your HVAC contractor when your hear this noise, as the problem may require replacement of the compressor.

Popping

Popping sounds can sometimes be heard in the ductwork when the air conditioner turns on and off. This is usually a ductwork problem which can be fixed during a simple routine maintenance check.

Buzzing

Buzzing is often heard from the outside unit, and can be caused by a variety of factors. Loose parts or debris stuck in the indoor or outdoor unit could be causing this noise, or it could be due to a loose outdoor fan motor or fan blades. In some cases, buzzing indicates a malfunctioning blower or refrigerant leak. To positively identify the source of the noise, have a professional check your air conditioner and carry out air conditioning service if necessary.

Hissing

Hissing noises usually come from the ductwork, and could be due to a refrigerant leak. It’s best to let a professional handle things if you suspect this is the problem.
