"Our furnace stopped working in North Chicago, IL on a night that dropped below freezing. I have two young kids and was panicking. Called JG Cool HVAC, got a real person immediately, and had a technician at the house within 45 minutes. He fixed a cracked heat exchanger, was completely upfront about the cost, and the house was warm again before bedtime. Absolutely recommend."
