Keeping Your Business Cool: Commercial Rooftop Unit Maintenance

Commercial HVAC demands are entirely different from residential cooling. Up on the flat, blistering hot roofs of North Texas commercial buildings sit massive package systems known as RTUs (Rooftop Units), like the heavy-duty Carrier model showcased above. These self-contained powerhouses combine the compressor, condenser, and evaporator components into a single massive steel cabinet. They require complex curb mounts to interface directly with the drop-down commercial ductwork inside the warehouse or retail space below. Proper maintenance on commercial units is absolutely uncompromisable—if an RTU goes down during a humid July afternoon, business operations can grind to a halt. SunDollar A/C & Heat provides rapid-response commercial diagnostics to ensure that these massive machines stay online, efficient, and capable of handling intense commercial cooling loads.
