Air conditioner for Moshe

Moshe, 61, was widowed two years ago and lives alone.
Due to a number of physical ailments, including kidney disease, difficulty walking and vision impairment, Moshe cannot work. He survives on a monthly government stipend and a disability allowance.
Moshe has an old air-conditioning/heating unit that no longer works and cannot be repaired; he cannot afford to replace it. The extreme temperatures have had a very negative affect on his health.
If Moshe could get help buying a new unit, there is no question his quality of life would greatly improve.
