Don’t let energy slip through the cracks
Be Wattsmart and save on duct sealing and duct insulation. When energy is lost through duct surfaces, heating and cooling equipment has to work harder to make up for the loss. As a result, you could be spending too much money to maintain comfort. Duct sealing and duct insulation can cut those heating and cooling costs by 30 percent.
|Duct Sealing (stand alone)||$375|
|Duct Sealing + Duct Insulation||$750|
Ensure the home qualifies:
- Duct sealing (stand alone): Must be an existing single family; new construction is not eligible

Additional requirements for duct sealing + 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 space must be insulated
- Services must result in final duct insulation of R-8 or greater
- Duct sealing + duct insulation must be performed in the same project, with insulation installed after the ducts are sealed.
Additional program requirements:
- Home may qualify for either duct sealing or duct sealing + duct insulation, but not both
- When applying for duct sealing + duct insulation, separate trade allies may perform the two services; the trade ally listed in section 2 of the application will receive the trade ally incentive
- Incentives are limited to one-time installations within the qualified space of the home and may not 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

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 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.
Residential electric customers residing in the state of California who purchase their electricity from Pacific Power on rate schedules D, DL-6, DS-8, DM-9 or NEM-35 qualify.
