I have been following advice by reading all the posts- most have been very easy to follow. My one question is I have gotten a couple of quotes and this is what I have found.
First company - very smooth salesman - had fancy laptop and measing tools to do a J-load. Got numbers he needed and said would mail me results. Before he left he gave me his guess - 2.5 tons a/c and 60 - 70 btus for furnance. Got the price - speachless.
2nd company. Retired employee - just does quotes. Says he can do a j-load - will do one later. But he used his old calcs - square foot (1600). Came up with same as the jload. Recommended 2.5 tons a/c - said 60 k btus would be min, but his calcs call for 68k. So would get a 70k.
this is the same as results that the first company gave me.
So I guess my questions is - my house is basic - rancher with about 1600 sq feet. Should I keep getting jload calcs or I should just be ok with the Jload calc that matches with both companies?
