This customer from Mattituck had a energy assessment because half of the second floor bedrooms were warmer in the summer than the other bedrooms. After examining the customer's house it was determined that one of their issues was that their supply plenum was not properly insulated. To help improve comfort in their bedroom, we wrapped the supply plenum with insulated duct wrap, preventing cool air from being lost into the attic. By doing this, these bedrooms will be much cooler in the summer because all the conditioned air will go to the bedrooms and not escape through the ducts to the attic. The house is also more energy efficient.
