"Heat went out in Greenfield, IL at the worst possible time." 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."

"I've been a JG Cool HVAC maintenance plan member in Greenfield, IL for three years. Every visit has been thorough and the technicians always explain what they found and what condition the system is in. This past spring they caught a refrigerant leak before it became an emergency. That proactive catch alone was worth the entire plan."
