They share one vision: to develop lifetime customers by providing quality work and the ultimate service experience in everything they do.

Our History

GSM Services is a third-generation company that has been in business since 1927. It originally started out as a small sheet metal shop and metal roofing company by W. Fred Long. He later passed the business to his son Ronald J. Long, Sr. in 1971, who then passed it to his sons Steven and Joel in 2005.

As the company expanded over the years, we took to duct fabrication, commercial roofing, commercial and residential HVAC, and energy services. We are proud of the ways our company has grown as well as the fact that we have never lost touch with our roots or sacrificed quality or service. We are excited about the future that we have in the Greater Charlotte community.

We understand the importance of family values, building relationships with our customers, and always providing the best services available. It's how we've been so successful for nearly a century, and we look forward to continuing to bring our values to our customers.

Community Involvement

GSM Services understands the importance of giving back to the community, and we are proud of the opportunities and partnerships we've had over the years. One of our favorite methods is through our pink van. This van is used for many projects, and proceeds from work performed using the van goes to Cancer Services of Gaston County.

Being in the community for almost 100 years, we have had the opportunity to work with many charitable organizations such as United Way, the Gaston County School System, the Boys and Girls Clubs of Greater Gaston County, Salvation Army, and the Shelter of Gaston County. We are proud of the impact we've been able to make in our community, and we look forward to future opportunities to give back. We also host & produce a podcast called "Gaston's Great" which highlights many of the non-profits and good things happening in our local community. Check it out now at!
