The Things You Find Out In The Garage: Part 2

by

Last week I showed you a venting system that wasn’t quite right, P1060856and mentioned the importance of having a certified technician review your HVAC and water heating systems. I wanted to cover a few more issues we discovered.

An important part of heating and cooling air is getting it to and from the home. This is what duct work is all about. In this system’s case, the plenum, or box where the return air from the home comes back to the furnace, also acts as a platform for this furnace and water heater to sit on.
Because it is where the furnace draws the air from the home, it is as you might imagine, connected to the inside of the house. And, as you can see in the second picture where the technician is looking into this plenum, there is a nice structural chunk of pressure treated wood, concrete floor and some moisture damage.
Pressure treated wood probably isn’t the best thing to have in your duct system, nor is dry rotted plywood, and this plenum is very much a part of the duct system.P1060858
It’s also not sealed. That means the garage is connected to the duct system and, therefore, to the home. Indoor air quality is important, and it should start with the air handling system. Stay tuned till next time!

Thanks,

Jason
