I have a room that never seems to get enough heat or AC. I have a
split level. The furnace is below the family room and the cold/hot
room is above the family room. You'd think that'd be a short-ish run
of duct work but it does bend a couple of times. I'm thinking of
putting a booster fan like

in. Do they work? Any comments on the brand or model I should be
aware of? I'd rather walk into my h/w store or home center and go
home with one but I can't find one locally. Is that to be expected or
have I just looked in the wrong places?


my house if very old i can only fit a 9 inch duct upstairs, in the summer temps would never go under 76 77 degrees i talked to 4 hvac specialist they all said it would cost over 4000 dollars to fix the issue. well i decided to try something a little different i used a 10 centrifugal fan pumping 1100cfm used an ribu1c which is just a relay powered of the thermaustat and just like that problem fixed my temps now hover at 68 plus the fan is whisper quiet. dont listen to these hvac people all they wanna sell you is an expensive piece of tin metal, my setup has been running for 2 years now no issues and also have installed it on 4 friends systems with no issues

Hi,
You may have poor insulation for the ceiling and poor vent for the attic.
