THERMWISE® BUSINESS REBATES
Increase your profit by decreasing your energy costs. Questar Gas’s business-rebates program rewards you for purchasing energy-efficient appliances and “downsizing” energy usage in your business.

The links below are provided for your convenience to identify qualified appliances and the equipment's efficiency levels. Not all appliances apply. If you cannot find your equipment within these listings, please contact your vendor or email ThermWise.Administrator@Questar.com to determine if your equipment qualifies.

Property owners of multifamily residential properties of five or more units are eligible for ThermWise Multifamily rebates. Refer to ThermWise Multifamily Property Owners Rebates Program for details and application form.

Please see Terms and Conditions before you apply.

Other gas-saving measures not included in either the Multifamily or Business Rebates program may be eligible for a custom rebate. Refer to the ThermWise Business Custom Rebates Program for details about measure eligibility and rebate levels.
