Attic Insulation - Ducts in the Attic

Ducts are in the attic because there is enough space for them, but it can also make them very inefficient. In the summer your attic is HOT and it heats up everything in it, including the ductwork. Cold, conditioned air is pushed through the hot ductwork to try and cool your home. Instead, the ductwork heats up the cool conditioned air making it significantly warmer and your home is harder to cool and your HVAC runs more to try and get the home to the temperature you want. You're left with uncomfortable rooms, high energy bills, and wear and tear on your HVAC system. (The reverse is true in the winter.)
