MGS is a grassroots HVAC company, owned and operated by Charleston natives.

Founded in 2018 by Ryan Wham, after spending more than 2 decades in the business at his Father’s company, Ryan added Nathan Laird to the roster in 2019, and with their combined 35+ years of stellar service in Charleston, MGS quickly gained a reputation for quality service, installation and reliability that stands out in this saturated HVAC market, filled with big companies run and backed by big investor dollars and little industry experience.

We are a true SERVICE company, not a sales company. Our first priority is looking out for the homeowner’s best interests, not trying to fill sales quotas to pay for franchise overheads.
