I agree with Sir CJ, you need to have the heat load calculated. There are a lot more factors involved than just the square footage of the structure. Cubic footage, R-value of walls and what they are constructed from, R-value and size of windows and how many, same for doors, the color of your roofing materials, the direction your house faces, the number of shade trees, the geographic location of the structure and a whole lot more. HVAC companies have books and software which are specific to your area to perform these calculations. No offense to the folks at Home Depot or Lowe's, but they cannot give you an accurate answer as indicated by the idiot who gave the first answer to this question, nor is it a job for you and a buddy. In fact it is illegal in all 50 states for anyone not certified by the EPA to work on any equipment containing any refrigerant other than R-134a. With fines ranging from $1500 to $25,000 it is just not worth taking the chance. You will also find you will not be able to purchase the equipment yourself without a HVAC License. This is done intentionally to prevent homeowners from killing or injuring themselves, or damaging the atmosphere by messing with equipment containing high pressure gases.

You need to get a exp HVAC tech to run a heat load calc on you home, becouse if you put to small of a furnace in you will be cold, it it is to large you will dry out all the wood in the house and be wasting money. if the A/C is to small it Will Run all the time and wast money, if it is to big it wount run enuf and you will eventaly burn up the equpment. So you realy need a HVAC Tech to come out and size the equpment. if it is new construction look in to a ground sroce heat pume a closed loop model it will cost more at the start but it will pay for its self in a few years.

The manufacturers should specify what square footage a model is good for - you don't want to get one that is not powerful enough, or it will run continuously and run up the bill $$$ big time $$$. You want to make sure to get one that will be cost effective for that size home, so check the manufacturer's specifications. If it is too small it will have to run twice as much to heat the house effectively.

Too big it will burn up? No! it will not control moister, in fact it's better to be a little less than more. Look at about 4 tons, with cooling units in lower and upper floors off the one unit below for good oil return. they have pre-charged systems that are quiet and you and your neighbor can install it yourself.
