The state still has $500,000 left in rebates for residents who buy energy-efficient appliances.
The money is left over from $8 million in federal stimulus funds to promote energy efficiency. Most of it was distributed in April and the rest was expected to be used up in June.
But some shoppers who reserved qualifying appliances with the federal Energy Star efficiency rating ended up not making the purchases, which has freed up the money for others.
The rebates range from $75 for freezers and dishwashers to $300 for central air conditioners and natural gas furnaces.
The rebates will be available until the money is depleted. Consumers must go online to reserve their rebates and complete an application form. Those lacking Internet access can call 1-877-379-7323.
More than 62,000 appliances have been purchased so far under the rebate program.
