The SEER rating is what tells you how energy efficient your central heating plus a/c is.
When I went out plus obtained the last central heating plus a/c that I had, I made a major error. And that was missing the point of looking into the SEER rating. This ended up costing me a lot more on my energy use than I was used to spending. If you do not understand or know what a SEER rating is or never heard of it let me tell you. The SEER rating is what tells you how energy efficient your central heating plus a/c is. If you do not have a high SEER rating you will be paying much more for your biweekly energy bills! I am actually thrilled that this older central heating plus a/c of mine with the awful SEER rating just died on me! I was able to get a brand new, new plus superb SEER rating central heating plus a/c to substitute it. And now I am actually not paying as much on my biweekly energy bills plus it feels great! I would have just got rid of the awful SEER rating heating plus a/c a lot sooner. But I did not do this because I had invested the money plus it would have been foolish to toss it all down the drain. So what I did was use portable heating plus air conditioner equipment when I could to offset the use of the central heating plus a/c component with the awful SEER rating.
