Glen Goodwin has been in the roofing business for six years and has seen many sizzling summers.
"I'd say this year. This year's been the worst. It's very, very hot this year," says Goodwin.
Goodwin's boss let his workers have the day off because of the heat and the possibility of rain. He says he didn't have air conditioning growing up.
"I don't have AC now, but I have fans, four or five of them. Keep cool. That's all I need. Saves me money!"
Angel Mitchell lives in this home and has a few window units, but say they don't work as well as they should.
And Mitchell dreads running any kind of errand because that means she has to get in her car which has no air conditioning. And she has two young girls who aren't too happy about it either.
"It's horrible especially for the kids. They get way more whiney and attitude-y and stuff when they're hot. They'd rather be in the garden tub we got in the front yard to cool off with!" says Mitchell.
13% of homes in America function without air conditioning. And doctors tell us it's a fine line between heat exhaustion and heat stroke, which is a medical emergency.
"If you are worried that someone has heat stroke, generally they become confused, they're not talking very well, you're not relating to them. A lot of times, the earliest thing is that they just seem off," says Dr. Shannon Waters with Greater Mobile Urgent Care.
Staying hydrated enough is a tough job because your body works overtime to cool itself down to begin with. Experts say an easy rule of thumb is to drink twice as much as you think is necessary.
