I have an energy hog condenser(3 1/2 ton) that is over 20 years old. In the summertime here in Palm Desert, CA my electric bills are over 300 dollars a month for a home of 1300 sq ft. During the hottest hours of the summer day it runs constantly and rarely shuts off. I own a rental three doors down and had the entire split system replaced last year but could not afford two systems at the same time. In the interest of saving some money, and since we rarely use our heater, my question is whether it would make any sense to replace just the condenser with a more energy efficient one, say 10 or 12 seer? If yes, would I need to replace the evap coil as well? Your professional advice would be much appreciated. Any recommendations for condenser brands?
Thank in advance for your help.
