Before- this job was horizontal exposed duct. The units were worn and the duct leaking.
We recommended replacing the units with downflow style to clean up the application and reduce the chance of water leaks.
After- we installed downflow units, capped all extra roof penetrations, and cleaned up the application.
The roof is now leak free, units are neat and operate properly. We removed the old unit frames and sealed the openings.

We can custom build your adapter curb or plenum. We have a full service sheetmetal shop to handle any project.

Existing makeup air unit with horizontal duct. Unit was badly worn and ductwork was leaking.  (see bottom photo)


We removed both the unit and exposed duct along with the condensing unit and installed a new Aaon packaged makeup air unit with digital control. We capped the duct openings and made the new system downflow with an adapter curb fabricated in our shop to eliminate water leaks and make a cleaner install.
