Knoxville, TN -- (SBWIRE) -- 05/08/2015 -- A recent compilation of residential energy use analyses from various agencies reveal an estimated 50 percent of home heating and air conditioning systems in America are operating below capacity. In most cases, the families affected fail to notice any evidence of this issue other than inexplicably skyrocketing energy bills. In an effort to help mitigate this problem in the Knoxville area, a spokesperson for Dean Plumbing, Heating and Cooling has launched the company's free diagnostic service for local residents.

Said the spokesperson, "A number of families simply turn down the air conditioning a few degrees in an attempt to compensate when their system isn't cooling properly. While this may not have a considerable impact on their electric bills at first, if a trend develops, it will become noticeable. That's when the problem truly begins. Catching the need for Air Conditioning Repairs in Knoxville early is crucial to keeping homes comfortable and maintaining a lower cost of operation, and we hope our free diagnostics will help with that."

The staff of Dean PHC recommends having an inspection carried out at least once annually to ensure heating and air conditioning systems are functioning as they should. Backed by nationwide industry experts, they also suggest this be performed during the off-seasons of spring or autumn when the units are least needed. This process should include the exterior unit as well as internal aspects, such as the vents and air ducts; otherwise, optimum air flow could be as compromised as the mechanical and electrical components.

Regardless of a unit's manufacture date, it could lose up to 5 percent of its original efficiency with each year of use. Adhering to a regular maintenance schedule has been deemed the most effective method of combating this decline. Routine upkeep can be performed during an inspection while additional repair needs will also be detected at that time.

Concluded the company representative, "We've been providing professional and affordable Air Conditioning Service in Knoxville for well over a decade now. This free diagnostic offering is just the latest step in our efforts to better serve our community. Though emergency repair needs come up from time to time, those annual inspections and routine maintenance can help reduce how often they happen. For those whose systems have reached the end of their service lives, we also offer new units and installation."
