Central air-conditioning systems are given an efficiency rating known as a SEER (Seasonal Energy Efficiency Ratio). This rating changes nothing about the amount of cooling that the system produces, it only addresses how much electricity it uses to produce that amount of cooling. The higher the SEER number, the less electricity is used. Each number increase on the SEER scale reduces the electrical consumption between 5%-10%. A typical 15-year-old or older A/C system is rated at 10 SEER. Updating  to today’s minimum of 13 seer would save you 15%-30% on the cost to cool your home. This is only the beginning.  Trane manufactures units to exceed even 20 SEER. This dramatically reduces the electricity used, translating to much lower cooling costs. This opens the door to multi-stage and even variable rate A/C systems. These options take energy savings to a totally different level. We are happy to explain your options when you consider replacing your heating and air conditioning system.
