Important! Rocky Mountain Power's planned changes to the incentives and equipment qualifications associated with our energy efficiency program will become effective November 14, 2012.
To be eligible for an incentive, ductwork will need to be sealed and insulated by a program qualified contractor.
Stop energy waste. Insulate your ducts and you could start lowering your energy bills today.
Heating and cooling can account for more than half of your home's energy consumption, but you could be losing as much as 30 percent of that energy through poorly insulated ducts. What a waste! When energy is lost through duct surfaces heating and central air conditioning equipment have to work harder to make up for the loss. As a result, you're spending too much money for a comfortable home.
When you add or increase the amount of duct insulation in your home you will increase the efficiency of your entire system – saving you money and ensuring consistent air temperature for extended comfort in every room.
Energy Saving Benefits
- Save as much as 30 percent more energy with properly insulated ducts compared to uninsulated ducts
- Stops energy waste through duct surfaces
- Reduce greenhouse gas emissions by using less energy to heat and cool your home
- Helps prevent duct condensation, which leads to mold and contributes to unhealthy air in your home
Prior to starting a project, find a contractor using the Utah Program Qualified Contractors list. Note that incentives must be completed by a Program Qualified Contractor. Review the Incentive Application with your contractor to determine eligibility requirements, incentive qualifications and review the list of required documents to submit for an incentive.
Incentive Application and required documents must be received within 90 days of the purchase or completed installation. Incentive checks are issued within 45 days of receipt of the completed and approved Incentive Application. Incentives are not to exceed the purchase price of the equipment or service. Equipment and service work may be inspected for compliance. Incentives are subject to tariff approval and may change with 45 days notice. Additional terms and conditions may apply.
Visit our Frequently Asked Questions page for questions regarding contractors or how to receive your incentive.
Duct sealing & duct insulation
|For homes with gas heat and electric cooling||$150||$50|
|For homes with electric heat||$300||$50|
QualificationsDuct sealing and duct insulation
- Work must be completed by a Program Qualified Contractor
- Duct sealing and duct insulation services must be performed at the same time to qualify
- Incentive available on existing ductwork only. Existing ductwork must be located in an existing home. Newly installed ductwork does not qualify for an incentive.
- Ducts must be located in an unconditioned space. Definition of unconditioned space- an unconditioned space is any space outside of the thermal envelope of the building that is not intentionally heated for occupancy.
- 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
- Program Qualified Contractor is required to perform CAZ testing, 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 ducts are sealed. Ductwork must be insulated to a minimum of R-6. Pre-existing insulation must be non-existent or less than R-2.
- Program Qualified Contractor must complete a program duct sealing and insulation worksheet
- Incentives are limited to one duct sealing incentive per duct system for the lifetime of the home
- Incentive application and required documents must be received within 90 days of completed service
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.
