Brought in 3 reputable companies who performed heat load calculations that resulted in different outcomes. Here are some specs.
current 5 ton system installed in 1996
1 large 7'X7' skylight in kitchen
I know you cant possibly do a calculation with that info (at least I don't think you can) but how do I know if a 5 ton is to large or a 4 ton is to small? The guy that came up with the 5 ton model took longer to make his calculation but also he said he did a more extensive process with involved measuring every room, ceiling....and some other things. The other guys ended up with 3.5 ton calculations but recommended a 4 ton.
The 5 ton guy said I was at 297000 btu's I think. Any help would be appreciated.
Also should I stay away from the allstyle coils all in ones, which is what I currently have or should I seperate the plenum and coil?
