What ton ac unit for 2200 square foot home?

Answer 1

You should have an ACCA Manual J heat load calculation done to properly size heating & cooling equipment. Back when electricity and other forms of energy were cheap, most home builders simply used square footage rules of thumb and oversized equipment. Then homeowners simply replaced what they had when the time came. Energy is no longer cheap so those days are gone. You would save yourself $ by buying only what you need size wise and in the efficiency rating that makes the most sense for the area where you live. For example a 95% efficiency furnace would not make sense in Florida or So. Texas but an 18 or 20 SEER heat pump would, whereas the opposite is true in Michigan or upstate NY where the cooling season is only 2 months long and a 13 or 14 SEER ac and high efficiency furnace would make sense. Do a Google search on HVAC-Calc and you`ll see what I`m talking about, you can also download a free trial version if you choose. In May I replaced my furnace and ac unit, though I got the same size ac at 14.5 SEER, I downsized the furnace to a 2 stage 75Kbtu(hi fire) that except for the coldest nights here in NJ, will operate most of the time in Low Fire or 52.5Kbtu. My previous furnace was 100K btu single stage, which was way too big and probably sized by the square footage rule of thumb. Nearly a 50% difference! I am in the HVAC service business 25 years, and that`s what I chose to do.
