Job Stories From Prince William County, VA
Hot Upstairs Bedrooms - Dumfries, VA

A Dumfries, VA homeowner had been dealing with hot upstairs bedrooms in the summer months for years. He tried replacing the A/C and got an attic fan, but nothing worked. He heard about Comfenergy from a friend, and gave us a call. 

Our estimator arrived at the house and noticed that the air ducts were going through the hot attic, making the cool air traveling through them warm. He also found several air leaks in the home and very little insulation. The hot summer heat was penetrating the barely there insulation, heating up the drywall, and then radiating down into the bedrooms. Imagine putting cold air in a box with an 125 degree F roof and expecting it to stay cool. 

We installed a radiant barrier in the attic of this home, which can slow the transfer of heat and reflect heat back to it's source. We also air sealed it and insulated it with cellulose. We also sealed and insulated the duct work with closed cell spray foam. 

Once the work was done, the Dumfries, VA homeowner was extremely pleased. He reduced his AC expenses by over 10% and enjoyed much cooler bedrooms during the summer months.
