PBA Tip of the Day brought to you by Travis and Tyler Ringe with ProSkill Services (623) 551-7473.The energy cost to run an AC unit in Arizona is often the greatest cost for a system over it’s lifetime. Luckily the Department of Energy has gathered the data and created the formulas to estimate these costs. The efficiency of an AC unit is based upon the SEER number. The higher the number, the more efficient the units and the lower its lifetime energy usage and cost. Over time the SEER number on an AC unit will degrade between 1-3% depending on the regular maintenance (or lack thereof) done on the unit. The older your AC unit is the more it will have degraded and the more energy it needs to maintain temperature. Contact ProSkill today for more information on SEER numbers and what that means for your a/c unit!
