It was suggested on another website that I pose this scenario here......
That's what our HVAC guy said was necessary. I'm building a pretty big house and was very shocked at the amount of ac we're having to put in. 6 zones--19 tons--yikes. I guess there is actually some overage due to the # of tons available on different units.
I walked the house with the HVAC man yesterday and he analyzed and marked where all the ducts would go. The zoning that he did seems very logical, however I don't know diddly about this!
At the beginning of our meeting, I asked him if he had done load calculations for the system. He said that he had. When I was shocked at the amount, he mentioned that 1 ton would handle up to 400 SF.
We are upgrading from Trane 12 seer units to Trane 19 seer units........I think those are the numbers.
I was just shocked. Does the ratio sound right?
Help!!! I'm about to spend a load of cash on this system and I guess I need some confirmation that it's a good thing to do.
