I have a bid from a reputable installer on these American Standard products to replace two 18-year-old 3.5-ton Trane units:
Alliance R22 3.5 ton: 2a7a3042a1000a
4-ton, single speed furnace: aud1b080a9481a
I live in hot, humid south Texas (two story 2850 sq ft home). I am not worried about heating. I do not plan to be in this house more than a few years so I do not want top-of-the-line equipment.
1. When the installer leaves, will he leave the schematics inside the condensors and taped to the furnaces like they did on the original equipment 18 years ago?
2. I can't find much technical information on the condensor at the American Standard or Trane website. Why? I would like to know the min/max amp service required and the recommended tube sizes. I have 3/8" and 3/4" copper runs now. Are these OK? The installer did not mention replacing the lines. Because of the design of my house, it would be very difficult to run new lines without tearing out part of the roof and walls.
I would really like to have the full tech sheet on the condensor. I don't understand why Trane/American Standard do not have these posted. I know people on this site do not like Goodman, but at least on its website you can find the full technical details for Goodman products.
