Montana-Dakota Utilities (MDU) offers several residential rebates on energy efficient measures and natural gas equipment. New furnaces and programmable thermostats are eligible for a rebate incentive if the equipment meets program efficiency standards. New furnaces must have Annual Fuel Utilization Efficiency (AFUE) at least 95% or greater. The rebate program is available to natural gas customers for existing home natural gas furnace replacement, fuel conversion and new home construction customers. Home builders are eligible to receive a maximum of 25 natural gas heating incentives on a calendar year basis.

 MDU issues rebate payments in the form of a check, not a utility bill credit. Application forms must be fully completed with equipment information such as invoice or receipt, brand, model number, serial number, installation date and dealer information. See program web site listed above to view application form or to see more program information. Only South Dakota residential MDU customers under service rates 60 or 66 are eligible for rebates.
