Absolutely! Simply replacing your system with the same size as the existing equipment in the home is simply irresponsible. The Department of Energy estimates that as many as 50% of homes in the US don’t have a properly sized or installed HAVC system. Using the square footage of a home to determine the size of system that is needed is highly inaccurate. There are far too many variables that come into play. For instance, a long, ranch style home with large windows on the front and back may require a different size air conditioner if the front of the home faces north or west. Simply changing the orientation by 90 degrees is all it takes to drastically change the load on the home.
