It is important to have your AC system in Frisco serviced by a professional on an annual basis. Without proper maintenance, your air conditioner can drop in efficiency every year. As you can see in this video, homeowners often take their AC unit for granted, and they could be losing a lot of money because of it.
Every year you let your air conditioner go without professional maintenance, it loses at least 5% of its efficiency. This means your energy bill increases, and your unit has to work even harder to cool your home.
When you choose a professional to service your unit, make sure he is properly licensed and insured. Also, check on any reviews of the company, or ask your friends, to be sure they perform quality work.
