I have a quick question for you guys. In the process of building a new home. 2 story home rougly 2500 square feet. I have 2 2 ton lennox xp 16 Hp's going in and 2 g71 furnaces as well. Here is my question.
The furnace located in the basement went in fine lots of room. I don't have the exact measurements and the proper vocab so please bare with me. coming from the long duct runs that run the length of the basement floor. There are to spots were the furnace gets its return air and then the feed size.
Now on the second floor there is a truss that was interfeering with the install the HVAC guy pointed this out to me and because of this were the long runs in the atic hook into the furnace the
output opening is 15x 15
return is 11.5x14.
Im not sure if this is going to be a problem it seems like the amount of CFM is going to be greatly reduced. LIke I said I would have never known but the HVAC guy noticed and told me that they are a few inches smaller than normal. What do you guys think in your opinion. Sorry for the lack of proper terms.
