Rooftop Unit (RTU) Services in Charlotte, NC & Fort Mill, SC
Efficient, Space-Saving HVAC Solutions for Local Businesses
Running a business in the Carolinas means balancing comfort, energy costs, and space. A rooftop unit (RTU) helps you do all three. Installed on the roof, these self-contained systems provide both heating and cooling through a single packaged design—perfect for offices, retail centers, and warehouses that need strong performance without cluttering floor space.
Our licensed and certified technicians have set up and serviced RTUs for everything from small storefronts to multi-level commercial buildings, focusing on reliability, energy efficiency, and day-to-day practicality. At Top Mechanical Service, we help local businesses across Charlotte, NC, and Fort Mill, SC, get the most out of their rooftop HVAC systems.

Open floor space for operations instead of bulky indoor equipment
-
Simpler upkeep with all components in one location
-
Lower energy costs through variable-speed fans and smart controls
-
Consistent comfort across large open areas
