There is no one-size-fits-all heating and cooling solution for homes. Several factors are considered when determining what size of a furnace you need such as square footage, geographic location, insulation, and ceiling height. Here in Colorado, we are in zone 3 which is one crucial factor to consider when finding the right furnace size. Also, the proper BTU will need to be determined. Learn more about understanding BTU and Colorado requirements. The SEER rating is an important factor in determining which cooling unit is the most energy-efficient for your home. Learn about how the SEER rating works and CO requirements. Determining what units are right for your exact home is the first step DALCO Heating & Air Conditioning takes when we do any new installation.
