flex duct to floor registers??

[pooka16]

I was told that flex duct cannot be used when getting floor or wall registers.....is this true?

We live on long island where both the heating and the A/c is important. Is one type of register installation better than the other.. for example.... wall vs. floor vs. ceiling registers?

Thanks

Philip,
We us them all the time however there may be a building code in you area that restricts it. Call the local county building inspector.

"properly sized" registers will perform equally regardless of ceiling or floor.

Generically speaking, floor registers are used in Northern applications to take advantage of the furnace being logistically in the basement & natural convection. Floor registers offer some disadvantage in terms of gathering dirt and are easily restricted by furniture & drapes.

Be sure to consult your HVAC contractor for his opinion as your home may have some unique considerations & ask about upgrading your IAQ products.

Flex duct (again properly sized is the key here)is fine for installations, some local codes may vary.

I like ceiling better...floor registers are usaully placed next to the exterior walls leading to longer flex runs. I place most of my ceiling boots on interior blowing toward window..cept on some custom homes where the retired snow bunnies want em on the ext. like they are up north.
