Hello, We are building a new home and it is around 1650sqft and we are either getting a Goodwin GSH13 or a Ruud UANL-JEZ Series. The guy with the quote for the Goodwin said 3 ton the other quote for the Ruud said 2.5 ton.... We are in Arkansas where temps frequent 100 degrees in the summer. Another important factor is we are getting a light colored metal roof and Using R28 SIPs for the exterior walls.
This site is great I have been reading tons of articles it is great to get opinions from folks not selling the product. Thanks for your time. Brian
