Challenge: next time you happen to have a phone / camera at your home, get a picture of the plenum box atop your air handler. Think it would be an interesting exercise to challenge eager and learning HVAC participants with more real-life photos.  

For the record, this is important stuff. After all, a properly designed and installed plenum box is essential for your HVAC system’s overall health and efficiency. Here’s a few reasons why:

Even temperature: Plenums ensure conditioned air is distributed evenly throughout by eliminating hot and cold spots.
Energy efficiency: Optimizes airflow and reduces pressure issues by allowing your system to run more efficiently, which can help lower energy costs.
System longevity: An efficient system with less stress on the components, such as the blower fan, is less likely to break down prematurely.
Air quality: The return plenum, together with a filter, is critical for cleaning the air before it is recirculated.

If you enjoy daily challenges, working with your hands, and never a dull moment, the HVAC industry and HVAC Technical Academy may be a good fit for you.
