Ensure the home qualifies:

• Must be an existing home, not new construction
• Must have a minimum of 10 linear feet of exposed ductwork located in unconditioned space

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

• Work must be completed by a Program-Qualified HVAC Trade Ally listed on the Program-Eligible HVAC Trade Ally List
• Work must be completed in accordance with the specifications outlined in the Utah HVAC Trade Ally Program Manual
• 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 Feet per Minute) minimum reduction
• CAZ (Combustion Area Zone) tests are required for properties with non-sealed combustion heating and water heating appliances

Additional requirements for duct sealing (stand alone):

• An electric heating system must serve at least 80 percent of the home's conditioned living space

Additional program rules:

• Mail all documents so they are postmarked within 180 days of the qualifying service completion
• Incentive cannot exceed project costs
• When applying for Duct Sealing and Duct Insulation, separate trade allies may perform the two services. The duct sealing contractor listed on the application will receive the trade ally incentive

Required documents:

• Duct Sealing and Duct Insulation Application, completed and signed
• Itemized receipt or contractor invoice
• IRS W-9 Form, if applicable*

*Applicable only to businesses and non-individual customers applying for incentives

Definitions:

Electric Heating: A permanently installed, ducted system consisting of an electric furnace or heat pump serving as the home's current primary heat source

Electric Cooling: 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 Heat: A heating system with gas, oil, or propane serving as the home's current primary heat 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.

Please see the Incentive Application for a list of required documentation and additional terms and conditions. Incentives and qualifications are subject to Utah Public Service Commission approval and may change with 45 days' notice. Additional terms and conditions apply.
