Don’t let energy slip through the cracks

Heating and cooling can account for more than half of a home's energy consumption, but as much as 20% of that energy can be lost through unsealed ducts. Help your customers increase heating and cooling system efficiency with duct sealing and duct insulation. We offer incentives to both you and the homeowner for this valuable service. While your customers enjoy the benefits of improved comfort, savings and healthier air quality, you’ll both pick up some extra cash.

Qualifications and incentives

Ensure the home qualifies: 

  • Must be an existing single family home. 

Requirements for both duct sealing (stand alone) and duct sealing and duct insulation: 

  • Home must have a ducted electric heating system, heat pump or gas furnace with central air conditioning serving 80% of the homes conditioned floor area. 
  • Must have a minimum of 10 linear feet of exposed ductwork located in unconditioned space. 
  • Pre-existing duct insulation levels must be R-2 or greater. 
  • All physically accessible ducts located in unconditioned spaces must be sealed. 
  • Duct sealing must reduce duct leakage to the outside by 50 percent or more with a 100 CFM (Cubic Foot per Minute) minimum reduction. 
  • Work must be completed by a Program-Qualified HVAC Contractor listed on the Program-Eligible HVAC Contractors List
  • Work must be completed in accordance with the specifications outlined in the Utah Technical Specifications Manual
  • A functioning carbon monoxide alarm is required when a combustion appliance is present within the confines of the structure. 
  • Work completed must comply with all building codes and standards. 

 Additional requirements for duct sealing and duct insulation: 

  • Pre-existing duct insulation levels may not exceed R-2 and must be replaced with at least R-8. 
  • All physically accessible ducts located in unconditioned living spaces must be insulated. 
  • Duct sealing and duct insulation must be performed in the same project, with insulation installed after ducts are sealed. 

Additional program rules: 

  • Home may qualify for either duct sealing or duct sealing + insulation, but not both. 
  • Incentives are limited to one-time installations within the qualified space of the home and cannot exceed the total cost of the project. 
  • Homes that have previously received an incentive through the program do not qualify for additional incentives if replaced. 
  • When applying for duct sealing + duct insulation, separate contractors may perform the two services. The duct sealing contractor listed on the application will receive the trade ally incentive. 
  • Submit all documents so they are received within 180 days of the qualifying service completion date. 
  • If installing for a multifamily property (up to 3 units per foundation), customer must submit an application per unit. For properties with 4 or more units, please see our customer Multifamily Program.

*Applicable only to businesses and non-individual customers, including landlords, applying for incentives. 


Electric heating is defined as a permanently installed, ducted system consisting of an electric furnace or heat pump serving as the home's current primary heat source. 
Electric cooling is defined as a permanently installed, ducted electric central air conditioner or heat pump serving as the home's current primary cooling source. Room air conditioners and evaporative coolers do not qualify. 
Non-Electric heating or cooling is defined as a heating or cooling system with gas, oil, wood heating, pellet stoves, or propane serving as the home's current primary heating or cooling source. 
Conditioned vs. unconditioned space - clarification notes: 
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. 
Incentives are associated with the most recent tariff filing approved by the Utah Public Service Commission. All incentives are subject to change with 45 days' notice. Additional terms and conditions may apply.
