This Vienna, VA homeowner was worried about a hot top floor, and high energy bills. The AC never met the set point on the thermostat and ran 24/7 in the summer months.
Solution
Comfenergy air sealed leakage in the HVAC ducting system, sealed the floor of the attic for energy loss, and then added a deep layer of TruSoft cellulose insulation to top it off. Now they are comfortable and using less energy. Challenge your HVAC guy to do that!!!
Project Summary
Evaluator: Scott Beers
This Vienna, VA home was using a ton of energy and still was not comfortable. The top floor was hot and the AC ran 24/7.
Air leakage around the duct connections was a source of the problem.
Sealing these connections with spray foam makes them not leak, and provides great insulation.
The entire main duct trunk line was encapsulated in closed cell spray foam too.
Tight quarters folks. Don't do this on your own!!!
The final product of the project called for R60 TruSoft cellulose insulation. All of the ducting was buried in this blanket of insulation.
