Carrier 38TRA024 (2 ton outdoor unit)
Carrier 58STA070 (3.5 ton indoor unit (gas burning)
I had the above equipment installed in a 950 sf brick home w/ full basement and with full sun exposure. 1 out of three estimates that I got for this house recommended a 1-1/2 ton system while the other two recommended 2 ton systems.
My question has not so much to do with the outside 2 ton unit which I am happy with, but it is the 3.5 ton gas furnace indoor unit that was installed. I was under the impression from the guy that installed the system that I was getting a 2ton system. After installation he told me that he installed a larger inside unit. His reason was that he wanted to get the air from the ceiling registers all the way to the floor. At the time he called it a "larger unit" ..after looking up the model # on the Internet I learned that it was a 3.5 ton inside unit. When he said "larger inside unit I figured it was like a 2-1/2 ton inside unit....not something as powerful as a 3.5 ton inside unit. Remember ...this is a 900 - 950 square foot house.
I know that in some situations it is OK to put a slightly larger inside unit compared to the outside unit, but a whole 1.5 ton extra???? Ina 900-950 sqft house???
