Customer Questions & Answers

How can I purchase an additional section of the vertical duct?

I need one additional section of the duct. Where is it available for purchase?
Asked by: Lowgear
If product was 96 inches as advertised you probably wouldn't have to buy additional duct.

Filter removal from the other side

I need the filter to be on the other side for removal. Can this be changed in the field?
Asked by: Northwoods1
We have a couple different sources for this item. Our current manufacturer makes the filter accessible from the top, and so it actually doesn't need modification in the field. This assembly is designed to house a standard 1" x 16" x 25" Filter.

What are the dimensions of the vertical section, specifically the depth?

The horizontal section is 16" high x 25" wide, so the width of the vertical section must be 25", but what is the depth?
Asked by: Larry
The Installation PDF says the collar is 10"x25" so that must be the vertical cross section measurements...

I have a return air duct made with wood (don't think it is up to code) I want to use these assembly to inplace of that. The problem is the return register is on the first floor; and this has to reach to the adit on second floor.
Asked by: gaquay
Hi gaquay, Your first step is to contact your local building department to determine what the code requirements are in your city. Once you have that information, you can purchase what you need and do a proper installation. Mike

Total assembled height is 81 inches, which is too short to reach most return air ducts running on the ceiling. Also cold air return elbow was not rounded as the picture shows. It was rectangular which doesn't allow the proper airflow like the one pictured. Took weeks to arrive at my home. Product was worthless to me and will wind up costing me weeks on my renovation project. Contacted HD and got no solution other than returning it to the store which was a giant hassle. All they had to do was send an additional section of ductwork but they wouldn't do that. A total bust.

Rated 5 out of 5 by from Well made After shopping local HVAC companies and finding that a shop would charge me $600 to fabricate the return, I purchased this. It is well made, easy to install and worked great! The only downside is it was not quite tall enough for my ceiling height.
