In the past, air conditioning has been accused of being the bad guy. Now, with one ear tuned to customers’ concerns, the industry is making air conditioners so much more efficient that you can save money by investing in a new one.There are a couple of guidelines to keep in mind. First, buy one with a high SEER (Seasonally Efficient Energy Rating). This is a gauge of energy efficiency. Today’s ACs can be found with SEER-30.5— as opposed to the SEER-6 you might have seen 20 years ago.
