There are two classifications for the ThermWise Weatherization Rebate Program. A single-family house is defined as four or fewer attached households. A multifamily residence has five or more connected home units. To get insulation, air securing, and duct related rebates, consumers will be needed to have rebate forms submitted by a ThermWise Authorized Specialist. For qualifying multifamily residences, a pre-qualification evaluation is still required. To plan a pre-qualification assessment, get in touch with Insulation Rebates at (888) 900-7017. The ThermWise Weatherization Rebate will consist of weatherization-efficiency procedures specified below in the Weatherization Rebates table.
Duct securing and insulation work completed by a ThermWise Authorized Contractor should be done with each other in order to satisfy the revised Questar Rebates Gas 2011 duct sealing and insulation specifications.
Air securing job completed on qualifying solitary family residences by certified service providers must fulfill curriculum specs.
For a home owner, property supervisor or property owner of a property around 4 systems (and is not specified on the Questar account), finish the Homeowner Addendum and send with the Weatherization Discount Application.
