Duct systems are often installed in attics where they’re out of sight and out of mind. But what you don’t see could be costing you a lot of money and affecting your personal comfort and indoor air quality.​

duct sealing
A leaky duct can cost up to $200 on your energy bill each year. APS offers rebates of up to $250​​ per system when a participating contractor seals your air leaks through the Home Performance with Energy Star program.​
eliminate air leaks

Duct systems often have poorly sealed connections, loose fittings or disconnected duct runs. The result can be cooled air blown into your attic or hot air pulled into your air conditioning system. At higher elevations, you’re losing heated air. You also risk exposure to potential indoor air quality problems.

Seal your home’s duct system to keep your heating and cooling costs low and ensure healthy indoor air quality.

duct leakage indicators
  • duct work insulation that has dark, discolored areas
  • rooms that are difficult to cool or heat, or seem stuffy or dusty
  • heat pump air that feels lukewarm or cold during winter
  • duct interiors often get dirty

​​​Work with your participating contractor to ensure your duct sealing is installed to the APS Quality Installation Standards. Your participating contractor is responsible for submitting the rebate application form to APS.
