As part of the approved ThermWise Weatherization Rebate Program a single-family home is defined as a structure with up to four attached residential dwelling units. A multifamily residence has five or more attached dwelling units.To qualify for insulation, air sealing, and duct related rebates, customers will be required to have measures installed by a ThermWise Authorized Contractor. Insulation work must be completed by a ThermWise Authorized Contractor (or as a self installation) in order to qualify for a rebate. For Tier 2, an additional increment of R.11 may be added in conjunction with Tier 1 or seperately only if recommended by an approved energy audit. For qualifying multifamily residences, a pre-qualification inspection is still required. To schedule a pre-qualification inspection please contact Brian Camp at 801-324-5118. The ThermWise Weatherization Rebate will include weatherization-efficiency measures listed below in the Weatherization Rebates table.
Duct sealing and insulation work completed by a ThermWise Authorized Contractor must be done together in order to meet the revised Questar Gas 2011 duct sealing and insulation specifications. Click here for additional duct sealing and insulation information.
Air sealing work completed on qualifying single family homes by authorized contractors must meet program specifications. Click here for additional air sealing details.
For a property owner, property manager or landlord of a property up to four units (and is not listed on the Questar account), complete the Property Owner Addendum and submit with the Weatherization Rebate Application.
