Brett Gremillion prepared to call in reinforcements at his South Side air-conditioning repair shop Tuesday as Chicago-area residents suffered through a third straight day of sweltering heat and humidity.
"During these hot days the air conditioner is working almost 24 hours a day," said Gremillion, who had taken calls from about 30 customers by noon, well above his usual total. "On days like today, I actually hire a few more guys to help me."
