Before & After Photos

This home in West McLean, VA had some attic insulation, but it was old, damaged fiberglass. The lack of proper insulation, especially during the hot summer months, was causing uncomfortable temperatures on the third floor as well as sweating duct work that was causing water damage. Luckily, Comfenergy has the perfect solution for this situation!

We removed the old insulation and made sure any points of air penetration were sealed. Then, we installed a blown-in cellulose insulation solution. 

We removed the old, traditional bat style insulation, air sealed the space with ZypFoam and installed Foamax insulation panels on the walls and roof of this attic.  This helped make the floor space in the attic useable and made the attic a fully conditioned space unimpacted by outside temperatures.  

Even a well insulated attic can get cold in the winter or hot in the summer.  That means that anything else in the attic can react to those temperatures.  HVAC ducts with cold air travelling through them in the summer or hot air travelling through them in the winter can be impacted by the attic temperatures.  Properly insulating these HVAC ducts and burying them in insulation can help.  

This Dumfries VA home had condensation along the HVAC ducts (duct sweating) due to external heat making its way into the home via uninsulated rim joists on the side of the house.  Hot air from outside was working against the cold air moving through the HVAC ducts and causing the duct sweating which was showing itself as water spots on the basement ceiling drywall and mold.  Our production team encapsulated the duct with spray foam and then administered Aero Seal to the inside of the system to eliminate the opportunity for conditioned air to escape.  This process will stop the duct sweating and keep the conditioned air inside of the HVAC duct from experiencing any external temperature influence.  The air will reach the rooms it is intended to cool or heat and reduce the need for the HVAC system to work as hard as it had been. Improved comfort and reduced energy cost for the homeowner.  

This Dumfries VA home was having comfort issues that the homeowner wanted to eliminate. They called us to come and help.  Our Home Performance Sales Pro Carl completed a no cost inspection of the whole home and identified a need for some work to be done in the attic which would help improve the comfort and energy efficiency of the home.  In addition to air sealing and installation of new Tru Soft cellulose insulation, Carl recommended having the HVAC duct sealed with spray foam at different points where joints and exchange boxes were allowing conditioned air to escape.
