Duct Sealing


Important! Incentives in the Home Energy Savings program have changed. Please see the Qualifications section below for more information.

Seal the leaks for big savings on your electricity bill.

Often concealed in walls and between floors, your home’s ducts are easy to overlook. Poorly sealed ducts can leak heated or cooled air, reducing your system’s efficiency by as much as 20 percent and unnecessarily increasing your electricity bill. If you have high summer or winter utility bills, rooms that are difficult to heat or cool, or stuffy rooms that never seem to get comfortable, leaking ducts may be to blame. By identifying and sealing leaks, you can make your home more comfortable and save money on your electricity bill.
