I just got a few estimates for my 792sq ft ranch on a crawl space and some say they would install a 70K BTU furnace and a 2 ton AC, others say they would install a 50K BTU and a 1.5 ton AC. One of them said that they will cut 4 10x6 heat supplies in the ductwork in the crawl space to condition (Heat) the space for the winter - a waste in my mind but they argued that it will keep the pipes from freezing.
The house is built in 1954 but I will have all new windows installed so, heat loss through the windows will be minimal.
Based on my readings on-line, a 45k BTU furnace and 1.5 ton AC should be sufficient??? Why oversize to 70K BTU and have the systems cycle on and off a lot?? I am in Michigan.
Any thoughts would be appreciated. Thank you in advance.
