Duct sealing and duct insulation

Get up to $750 cash back

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.

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 Washington who purchase their electricity from Pacific Power on rate schedules 16, 17, or 18 qualify. Landlords who own rental properties served by the company in the state of Washington where the tenant is billed on rate schedules 16, 17, or 18 also qualify for this program.
