    I finally got the work done and couldn't be happier. The contractor put in 3 supplies as shown in the last figure, and one air return.

    It turned out the return was not necessary - if I leave it...

    I finally found a contractor who will do the work. He told me I could expect a maximum 3 degree temp difference between the sun room and the rest of the house. Is it too good to be true?

    He also...

    We are using the room under the sun room as a root cellar in the winter. With the register it will be heated and we'll lose the cellar. Not that we have to have a cellar, but I'd like to see how much...

    I see. Thanks. Either the contractor wanted to make some extra bucks or wanted to scare me away from zoning, he was telling me I need to have Infinity stats for all the zones in order to work, and it...

    Which one is better? Sorry for so many images. I was trying to edit my drawing but all versions are showing up.

    I read from another thread that I should not have the supply too close to the end of the trunk line. But having the last supply some 16" from the end of the trunk seems impossible because I'll need...

    I was not saying I'd zone a sun room against the whole house. Since I have 3 trunks off the plenum (one for living room area, one for bedroom area, and one for the basement), I was thinking putting...

    Does it mean after I extend the duck work, if I have any problem with the temperatures not balanced, I can change the blower speed to high to reduce the temperature difference in the house?



    I...

    Thanks again George2. But isn't 1,400 cfm too small for my house? I thought I need 1 cfm per sqft, and that's 4,400 cfm. If I go by 6" supplies at 100 cfm each, with 14 registers up and 9 registers...

    How many cfm is it if the blower size is 42? Is it 1400 cfm or 4200 cfm?

    George2 and motoguy128, thanks for your input.

    The furnace model # is 58MVC080-F-10114. Is the blower size 14 and furnace 80,000 BTU?

    I did a load calculator using the tool at...
  12. Sorry for my ignorance, George2. Is each 6"...

    Sorry for my ignorance, George2. Is each 6" supply 100 cfm max? Or with a bigger furnace and fewer supplies, each 6" supply can provide more than 100 cfm?

    I didn't understand what you meant by...
  13. On either coast or anywhere USDA zone 6 or above...

    On either coast or anywhere USDA zone 6 or above I'll just go with a mini-split. The problem is, in MN (zone 4) a mini-split is only half the solution because the heat pump will stop working before...
  14. George2, thanks for suggesting shutting the foyer...

    George2, thanks for suggesting shutting the foyer register. That room doesn't need to be that warm anyway.

    I was told by the two guys who will do the duct work that zoning may not help the sun...

    Thanks for the replies!

    My house is a rambler with full basement. The basement is almost all finished so it's hard tell exactly how the ducts are laid. As far as I know there are 3 trunks off the...
  16. Max number of supplies off one trunk and max distance between register and furnace?

    I am planning on adding heat/AC to a sun room that's connected to our family room. The trunk line for the family room side of the house stops at about 3' from the sun room. This trunk line also...
