Today I visited to determine why the upstairs playroom and hallway felt warm and humid. I found one of the panels was left off of the air handler and the unit was pulling in air from the attic. This is resolved. The AC that cools this portion of the home is a 4-ton Carrier unit from 2019. While investigating the humidity problem I learned there is a mold/mildew problem in the ductwork. Replacing all of the ductwork would be an expensive and burdensome project. The simplest solution will be to install a whole home air/surface purification system in each air handler. This device works to eliminate mold, viruses, bacteria, odors, and VOCs from all of the air and very hard surface. Installing this costs $1,506 per unit. I’m aware of four systems in the home.
