Is that old heating and air conditioning system getting ready to break down? Are you facing the prospect of an air conditioner repair? Have you had it for a long time and looking to make an energy-efficient upgrade? If you answered “yes” to any of those questions and you’ve done any type of online homeowner on the issue, you’ve probably come across the term “SEER.” But do you know what SEER stands for? You should because it’s very important to the long-term efficiency of your new system. SEER = Seasonal Energy Efficiency Ratio. That’s a fancy way of saying SEER describes the efficiency of your new HVAC unit. If you have an old air conditioning system, the SEER is probably in single digits. That’s not to say your old air conditioning company ripped you off – but technology has come a long, long way in just the past decade. Companies like Elmer’s One Hour Air now install systems with a minimum SEER of 13. Some units, like ductless models, can have SEERs in the 26-28 range. So here’s why SEER should matter to you. First, CPS Energy offers HVAC rebates if you buy a new air conditioner and heater system with a SEER of 15 or higher. You get a more efficient system, you save money on your electric bill over the long run and the utility gives you some of your initial investment back. That’s a win-win-win.
