Before & After Photos

This Sterling VA attic received several steps and services to improve the comfort and energy efficiency of the home, one of which was having the HVAC ducts running through the attic encapsulated with spray foam.  The metal ducts had been susceptible to temperature issues when the attic would heat up or cool down depending on the time of year and weather outside.  When the attic was hot and cold air was passing through the ducts, the conditioned and cooled air would not reach the rooms it was intended to before safely.  When it was cold and there was heated air passing through, the cold ducts would work to reduce the heat of that air.  Encapsulating the HVAC ducts with spray foam keeps the air inside safe and helps to reduce the energy cost to create more heated or cooled air.  

Whole house fans are GREAT!!  (For about 2-3 weeks of the year) For our geographic area.  It's way to humid and hot during most of the summer, and way too cold obvisouly in the winter.  During this 45-48 week time period, they do nothing more than allow energy loss in a home.

The before/after pics that follow show you what Comfenergy can do to allow you to keep your whole house fan for when it makes sense....but not loose energy the rest of the year!

This homeowner had moisture damage from sweating ductwork. In the 'Before' picture, you can even see the moisture pooling on the duct! The ducts were not insulated and the attic was poorly insulated. We applied our Tight 'N True encapsulation system to the sweating ducts to ensure that they stay dry and the house stays comfortable. 

This attic had very little insulation and there was significant air leakage occurring, which was causing comfort issues in the home and high humidity. The blown-in cellulose will now keep this attic properly conditioned and further insulate the vents/ductwork.
