Land O’ Lakes AC Guide: Common AC Noises and What They Mean

February 4th, 2013 by Charlene Ierna

Most homeowners are not professional air conditioning technicians. It is part of the responsibility of being a homeowner, though, to recognize irregularities in the performance of your home comfort systems and to contact a professional service provider when necessary. Still, it can be difficult to understand when professional service is necessary.

At Ierna’s Heating & Cooling, we believe that the best way for homeowners to make informed decisions is simply to provide them with information. If you notice strange noises coming from the air conditioner in your Land O’ Lakes home you should call a professional. Here are some of the possible problems you may be facing.

A high pitched whine coming from your air conditioner may indicate a slipped belt or a lack of lubrication on some moving part. Both of these potential problems should be dealt with immediately. Insufficiently lubricated moving parts will wear down faster than they ought to, leading to system damages.

Any grinding sounds coming from your outdoor unit merit a professional service call to your Land O’ Lakes home immediately. The chassis of the outdoor unit will need to be removed. It is possible that the moving components are dirty or that twigs, leaves and other debris have made their way into the system.

If you notice the development of a rattling or banging sound indoors while running your air conditioner you may have a problem with your air duct system. Problems with your ductwork can be especially problematic, as they can not only reduce efficiency and damage your air conditioning system but may also result in poor indoor air quality. If your air ducts have loosened since their installation or are fitted together loosely they will move around, allowing for gaps and cracks in the system. The banging of the air ducts may be the result of this looseness. These gaps allow air to escape and pollutants to enter the ductwork system.

Do not take strange noises emanating from your air ducts lightly. They may be indicative of serious problems. Contact Ierna’s Heating & Cooling today to schedule any necessary air conditioning repair services. We’ll make sure that the air conditioner in your Land O’ Lakes home is as efficient and effective as possible.
