Questar Gas provides rebates for residential customers who make their homes more energy efficient by installing certain energy saving appliances, efficient heating equipment, and certain weatherization measures. Incentives are available for clothes washers and dryers, water heaters, furnaces, boilers, windows, insulation and programmable thermostats. A reduced-cost home energy audit is also available to residential customers. The cost of the audit is refundable if customers pursue the recommendations made in the audit's report.  

To qualify for rebates, appliances and equipment must run on gas and must meet the minimum efficiency levels stated on the program web site. The website maintains a list of appliance models which meet the program requirements and local vendors who sell them. For more information on incentives, program guidelines and terms, and to access rebate applications, visit the program web site or contact Questar.
