Case Study: Energy-Efficient RTU Replacement for Aaron’s Rentals in Cartersville, GA
Commercial HVAC Challenge
When Aaron’s Rentals in Cartersville began experiencing serious comfort issues, it quickly became clear the problem was more than routine maintenance. The building was designed to operate with three rooftop HVAC units (RTUs), but only two systems were functional, and even running at full capacity, the space could not maintain proper heating or cooling.
The original RTU had surpassed its usable lifespan and was no longer repairable, forcing the remaining systems to overwork. This not only caused temperature inconsistencies throughout the building, but also resulted in inefficient energy usage and higher operating costs—a common issue many commercial facilities face across West Georgia and Northwest Georgia.
Mastertech’s Energy-Efficient Solution
After a full system evaluation, Mastertech Heating and Air recommended replacing the failed unit with a modern, high-efficiency solution designed to restore capacity while reducing long-term energy waste.
Mastertech coordinated a crane lift with Maxim Crane Works and installed a new 7.5-ton rooftop heat pump system. The unit was professionally set, sealed, wired, and integrated with the existing HVAC infrastructure—bringing the building back to full operational capacity with an emphasis on efficiency, reliability, and performance.
The Results: Comfort Restored & Energy Costs Reduced
With all three RTUs operational again, Aaron’s Rentals immediately saw improved temperature consistency throughout the building. More importantly, the new system reduced strain on the other rooftop units, allowing them to run more efficiently and extending their service life.
The result was:
- Reliable heating and cooling across the entire facility
- Improved energy efficiency
- Reduced long-term operating costs
- A more comfortable environment for employees and customers
