GLS Heating & Air Conditioning, Inc.

GLS Heating & Air Conditioning, Inc. has served the Williamston community and surrounding Mid-Michigan areas since opening its doors, positioning itself as a local option for residential heating and cooling needs. The company holds an active contractor license and maintains standard business hours from 7 AM to midnight daily, offering weekend availability that some area competitors lack. With a rating of 3.3 stars across 16 customer reviews, GLS attracts both positive and negative attention from local homeowners, creating a mixed but measurable reputation in the regional market.

Former customers describe markedly different experiences with this contractor. Charles Greenberg praised technician Nick and his team for what he called expert, efficient work on an HVAC project, while Marissa G alleged the company installed a rusty used inducer motor and acted dishonestly about the replacement parts. Josh Granger reported same-day service resolution for his central air, noting the company installed his current unit over two decades ago and continues maintaining it. The contrast in reviewer experiences suggests service quality may depend on which technicians complete the work and possibly on job complexity.

Negative reviews raise concerns worth noting. Patrick Barnard reported the company cancelled three scheduled appointments without notification, forcing him to call repeatedly. Brian Keel and Steve Chappell both described difficulties reaching anyone at the company, with Chappell waiting over three weeks for a return call about new equipment quotes. These accounts appear repeatedly enough that prospective customers should factor communication reliability into their decision-making process.
