A. From our EXPERT Richard Ciresi – owner Aire Serv® of Louisville Great question…many answers. First and foremost is MAINTENANCE. The equipment needs to be cleaned and serviced by a licensed professional at least twice per year. Studies have shown that lack of proper maintenance can reduce equipment efficiency by 5-10%. In addition, most of today’s filters need to be changed a minimum of every 90 days, and don’t skimp on the filter. You should use a filter that has a high efficiency rating to help keep your air and equipment clean. After thorough cleaning, the service technician will adjust the Freon levels in your air conditioner to the manufacturer’s specifications. Keep in mind that an over charged unit is just as bad as an under charged unit when it comes to energy consumption. On the heating side, the burners should be cleaned for maximum performance, as well as adjusting the gas pressure, and cleaning the blower wheel. We also recommend that you leave your indoor blower running
