After inspired design work, the group completed flex work without hesitation. We decided to get creative with the runs… check out the photos. Over the next three weeks we will be troubleshooting and getting down to HVAC hands on basics, component swaps, more brazing, lots of PM’s, and that’s just to name a few hands-on stuff we will tackle.
Ducts & Air Flow
Plenum and Air Distribution
For those who experienced discoloration (cannot say the “m” word here) atop your air handler, improper plenum construction and implementation is most likely the cause. One of the many hands-on tasks at HVAC Technical Academy concentrates on is proper supply plenum construction and attachment.
Air Traffic Manager: Plenum
There are two primary types: the supply plenum, which distributes air from the system to the home, and the return plenum, which pulls air from the home back into the system.
In a way, supply and return plenum acts as a “traffic manager” for air, ensuring consistent pressure and temperature regulation.
HVACTA: Plenum Progressing
When it comes to system swaps, proper air distribution is essential to air flow and cooling efficiency.
One of the many hands-on tasks at HVAC Technical Academy is constructing supply plenum.

This is Kevin from HVAC Technical Academy, and I’ll be here today to talk to you guys about duck board and cutting duck work.
HVACTA: Plenum, for YOUR health
More than a simulation, it’s all about air flow. Every participant got their hands in the mastic, tape, flex, and design. Now the group will be introduced to even more HVAC opportunities.
