we had a 2 ton 13 seer contractor line in our old house 1032 sqft bungalow
worked well but was loud ( could hear the compressor running in the house ) which was ok as it was right under my old azzhat neighbours master bedroom window lol
in our new house 1500 sqft modified bi level with the master bedroom over the garage ( southwest facing )
went with a 3.5 ton 18 seer unit with a scroll compressor as per my friends recomendation who did the sizing and install
this 3.5 ton unit is super quite compared to the old 2 ton unit in the old house
cost difference all in was about $500.00
