How do you know when it’s time to invest in a new air conditioning system? It’s a big decision for a homeowner. We understand. But here’s the good news – a new, energy-efficient air conditioning system will actually pay for itself over time through energy savings! There are a few factors you have to keep in mind for that promise of energy savings to come true: SEER and sizing. SEER What is SEER? It stands for Seasonal Energy Efficiency Ratio. In simple English, the higher your AC system’s SEER rating, the more efficient it will be. In fact, CPS Energy offers rebates on higher-SEER systems. Rebates start with systems rated at 15 SEER and increase the higher the SEER. Ductless AC systems can go all the way to 28 SEER. Your home comfort specialist can walk you through your best rebate options. Sizing The second major factor in terms of efficiency is the size of your system. There’s a common misconception that the bigger your AC system, the more comfort it will provide. That’s not true! Purchasing a system that is too big is a waste of money. A larger than necessary system will turn on and off so much, so quickly that it won’t pull the needed amount of humidity out of your house. On the other hand, purchasing a system that is too small will mean it has to run for a long time to cool your home. So you want to take Goldilocks’ advice and have an air conditioner that is just the right size. Have the square footage of your home (including the size of your rooms) handy so a technician can advise you on the right size of system you’ll need.
