I'll never call another HVAC company."

"Our furnace stopped working in Williamston, MI 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."

"Signed up for the JG Cool HVAC maintenance plan in Williamston, MI after a bad experience with another company." 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."

The location that was later to become Williamston started as the cross-road of the Grand River and Saginaw Indian Trails. It was first occupied by a small band of the Saginaw tribe of the Chippewa People which by the mid-19th century used the area as a 'summer village' (it was not used by them year-round, but they 'wintered' in the area that is now Meridian Township). They used Williamston for planting crops, burying their dead, and holding an annual spring gathering, primarily using the land just north of the Red Cedar River.
