I have to replace a 2.5 ton a/c & gas furnace. Heating load done =23,228 & cooling load = 27,206. 1500 sq ft ranch with small room over attached garage. I live in SE VA with relatively mild winters & sometimes hot summers.
I got estimate for 2 units:
York Affinity 3 ton a/c 15 seer, 80k btu 80% modulating gas furnace. Honeywell prog t-stat, lifetime warranty on compressor & 10 yr parts & labor. i believe he said it was a 2 speed a/c which I was told would help with short cycling. I wondered if this unit may be oversized, but I was told .5 ton is not that big a deal and the 2 speed would help with short cycling.
York Latitude 2.5 ton a/c 14.5 seer, 80k btu 80% single speed gas furnace. same t-stat, 10 yr warranty on compressor, 5 yr parts, 1yr labor.
Then I was told by someone i know that I should look into a dual fuel system-- heat pump with gas furnace back up. Now I don't know what to do.
Any suggestions? Pros & cons?
