Replacing your homes heating and cooling system is a major decision, but you need to think more than just about the initial purchase price. Factor in how much you can save on your current energy bill by replacing your older system with a higher efficiency system.
The way your home is constructed can affect the size (capacity) of your air conditioning and heating system. For example, insulation R-values have a great deal to do with heat and cooling loss in your home. The type of windows, single pane, double pane, tinted, etc, have a lot to do with how much heat or cooling loss you will have. Homes built in the last 15 years are of a much tighter construction and better insulated then older homes, therefore there is not as much heat or cooling loss. The older the home, the looser the greater the chance for heat to be lost.
