Typical Subdivision BS..always the cheapest units they can buy...
I am running two units for 9 tons...on a 3700 sq. 1 story trailer. But then I live in an oven in the summer. The 5 ton unit carries the most of the load, as the trailer faces N/S. The bedrooms get the morning sun and have the garage in front which insulates the bedroom area..so even during the heat of the day the 4 ton unit hardly even runs. I have planted 5 trees to the west to block the late afternoon sun and have one in front. My thinking is this would help shade the house in late afternoon. One thing about trees is that even if they don't shade the house they do keep the ground temp down around the house Further I have LOW E windows and Solar Screens all in an effort to keep it Kool without running up the E Bill. Also to help with cost I have the Pwr Co have a cut off during heavy usage times of the day, this usually saves about $40 a month in the summer plus I get a check for about the same at the end of the year. I am probably going to put in an attic fan to blow out the heat. It gets up to about 160 in the attic in the summer. Costco has a Solar powered attic fan for $270 which is a consideration.
Just had to replace a Compressor on the 5 ton unit..OHH JOY! that was 14 I coulda done without...
Also one might consider that people spend most of their time downstairs.
