I have a arcoaire 3 1/2 ton 12 seer ac with a 2 ton coil. My house is under 800 sq ft, Ranch. The system is just a few years old and the house cools good. The cooling costs are under $70.00 for the whole season. The inside humidity in the summer is 40-50% humid when set at 71 degrees. I realize that the condensing unit is grossly oversized for this house. What are the possible advantages/disadvantages to having such a large condensing for such a small house?
