BISMARCK, N.D. (AP) - Scorching weather in North Dakota has sparked a state effort to buy air conditioners and fans for low-income residents with medical conditions.

The state announced the program Wednesday, saying that the 100-degree weather can be life-threatening.

Qualifying households can get a voucher for up to $300 from their local county social services office to buy a window air conditioner and fans.

Ron Knutson, who runs the Low Income Energy Assistance Program for the state, said he did not know how many people would take advantage of the program. He said doesn't want people to hold back because they are too proud or don't want to "bother" someone else.

"Many people in North Dakota are reluctant to ask for anything," Knutson said.

The option to use the state's low-income energy assistance fund for air conditioners is not new but it is not usually invoked in North Dakota, he said.

The fund being used usually pays to repair and replace furnaces for qualifying homes, he said. It has about $1 million that can be used through Sept. 30.

To qualify, the household must have at least one person with a medical need that makes him or her vulnerable to heat-related illnesses. Knutson said a note is needed from a medical professional verifying that he or she has a condition.

A three-person household earning up to $34,459 per year may qualify if their assets meet program requirements. People's homes and cars are used in the asset test.

The air conditioner voucher program will last through Aug. 31.
