Important! Changes to the incentives and equipment qualifications associated with the program were approved by the Public Service Commission of Utah and became effective on September 1, 2010.

To be eligible for an incentive, ductwork will need to be sealed and insulated by a program qualified contractor.  

Seal the leaks and you could save big 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 could save money on your electricity bill.

Incentive for duct sealing and duct insulation installed on or after September 1, 2010

For homes with gas heat and electric cooling 
$150 customer incentive and $50 contractor incentive for sealing and insulating ductwork

For homes with electric heat
$300 customer incentive and $50 contractor incentive for sealing and insulating ductwork

To be eligible for the duct sealing and duct insulation incentive, both services must be performed at the same time to qualify. The following requirements must be met:

• Duct sealing and duct insulation must be completed by a Program Qualified Contractor. A Program Qualified Contractor has been trained by the program and meets all of the program’s participation requirements.
• Existing ductwork must be located in an existing home. Newly installed ductwork does not qualify for an incentive.
• Ductwork must be located in an unconditioned space. An unconditioned space is any space outside of the thermal envelope of the building that is not intentionally heated for occupancy.
• Clarification Note: For the most part, basements are conditioned spaces. Basements are not usually thermally isolated from the main living area and contain space conditioning ducts.  Basements are also used for storage and frequently contain laundry facilities and other living spaces. Ducts serving unfinished basements are not always equipped with dedicated supply registers, although single registers at plenums are not unusual.
• An unconditioned basement would have these properties: Thermally isolated from the main floor by insulation in the floor. Insulated, weather-stripped door (if above floor plane) and insulated stairwell walls where thermal plane penetrates floor, air sealed (caulked, foamed penetrations) wiring plumbing, sealed duct penetrations and sealed, insulated ducts. No supply registers.
• While a crawl space is unconditioned space, the floor must be insulated prior to or at the same time ducts are sealed and insulated to thermally isolate the crawlspace.  Failure to do this will increase the heating load of the home and potentially cause comfort issues.
• There must be a minimum of 10 linear feet of exposed ductwork. All exposed ductwork must be sealed and insulated (ductwork only, not venting).
• Home must have an electric heating system or a central air conditioner serving 80 percent of the floor area
• The Program Qualified Contractor is required to perform duct leakage testing and seal ducts with mastic. Duct sealing must reduce duct leakage to outside by 50 percent with a 100 CFM minimum reduction.
• Duct insulation must be installed after the ducts are sealed. Ductwork must be insulated to a minimum of R-6, R-8 in attics and pre-existing insulation must be nonexistent or less than R-2.
• Contractor must insulate with duct wrap (backed duct insulation with a flame spread of 50 feet or less) and fasten with banding (mechanical fasteners) every 24 linear inches. Compatible tape may be used on insulation seams to create a continuous barrier. Both services must be performed at the same time to qualify for an incentive.
• Newly constructed homes (built in 2000 or newer) do not qualify. Remodeling projects may not qualify if the upgrade requires a building permit. All work must be performed to program retrofit standards.
• A duct sealing worksheet must be completed by a Program Qualified Contractor and submitted with the incentive application to the program for review.
• Application must be received within 90 days of completion of service. Additional qualifications listed below.
