Most houses with say 2,000 sq ft. in central PA have 2.5 to 3 Tons of AC installed. If I had whole house and needed a unit I would go no larger than 2 Ton. on a hot day (90F in PA) those compressors cycle mega times. It makes more sense to have a smaller unit that DEHUMIDIFIES way more than a larger unit.
I have a ranch type house and use window units.I have a 6,000 Btu unit in my addition that is 20x20 with a cathedral and 3 exposed walls. Now that room has a doorway and a "window opening" to the rest of the house. If it remains warm at night I sometimes run the unit 24/7 and the temp in the addition will be maybe 76.5+. If I closed the door it would be cooler. I do have AC window units in both my bedrooms and they are 5K Btu.
If I run all three the house is comfortable but right now (only running it16 hours/day its 77F....BUT... the humidity is 37%. It is honestly quite comfortable. I realize contractors over install by 30%bc they obviously don't want calol-backs.
My point of posting.
1. I enjoy arguments
2. It may get a person or two to rethink capacity if they are installing a new outdoor unit. The more it runs the more it dehumidifies. Even for a window unit. It is recommended 1/2T for 250 sq ft. And remember I have 400 sq ft and a cathedral ceiling and have a 1/2 T unit.
