SEER is not used to size the heat and air system, it is an efficiency rating. the higher the SEER, the less it costs to operate. get quotes from local contractors- preferably at least 3 different ones, and make sure they give you a 'load' estimate. the load estimate takes into account the square footage, age, type of construction, insulation, number of windows and doors, etc. to determine how many btu's it will take to heat and cool your house. there is no longer a good rule of thumb of btu's per square foot with the high efficiency units out there on the market. if the contractor won't do the load estimate and share it with you, find another one! high efficiency units are only as good as their installation-the highest efficiency unit installed incorrectly is worse than the least expensive unit installed correctly.
