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!!!
