Southwest Gas Corporation - Large Commercial Energy-Efficiency Boiler Program

January 03, 2013


Southwest Gas Corporation (SWG) offers rebates to commercial customers in Arizona for the maintenance service and equipment for existing boilers and for the purchase and installation of new, non-condensing boilers. Customers should contact SWG to ensure rebate eligibility and availability prior to purchasing equipment. Due to limited program funding, participants should submit rebate applications soon after purchase, installation and/or service. Customers must include a signed rebate application, SWG gas account number, copy of receipt or invoice stating where the equipment was purchased, the date(s) of purchase, the contractor(s) that serviced/installed the equipment, the date of service/installation and if applicable, the combustion analyzer test (one of the nine requirements for the boiler tune-up inspection). Please visit the web site listed above for other details or contact SWG.
