"Heat went out in Buffalo Grove, 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."

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."

Before westward expansion, Native American Potawatomi tribes inhabited the present area. The name "Buffalo Grove" comes from the English translation of the Potawatomi name for Buffalo Creek, which flows through some of the village. Initial Homesteaders sold their land to agricultural Catholic German immigrants, who established St. Mary's Church and a school. The rural area changed minimally until post-Korean War developers bought and suburbanized the region for veterans. After being incorporated in 1958, Buffalo Grove experienced a population boom for the next three decades and hosted a 50th Anniversary Celebration in 2008.
