Air & Duct Sealing

According to APS and SRP, a typical home wastes 15% - 20% of its conditioned air through duct leakage- the equivalent of leaving a window open at all times.  Duct leakage can contribute to hot and cold rooms, dust and indoor allergies, and a soaring utility bill. Most homes in Arizona have ductwork located in unconditioned attic space, where temperature differences can be extreme. Any leakage results in the HVAC system working significantly harder than it should and a much higher utility bill.

​It's time to stop throwing your hard-earned paychecks at your utility company and enjoy a more comfortable and healthy home by testing and sealing your duct lines. Schedule an energy audit with Green ID to identify exactly where your problem areas are and learn how much you can save for each upgrade. We also facilitate all the utility rebates and tax incentives for your convenience.
