Elderly couple in need of AC repair

My name is Mark. My family and I have been going to the Dollar Tree where we’ve encountered this elderly man working part time because his retirement ran out. Recently, his air conditioner has gone out. In July in Arkansas. He said it will cost 3-4 thousand dollars to repair. We would love to bless him with financial help but need help from others. He’s such a sweet gentleman and I know any amount we can give will be well received. Thanks in advance to those that choose to give!
