Commercial HVAC systems are designed around very specific assumptions about how a building will operate. During the engineering and construction phase, mechanical designers calculate cooling loads based on factors such as occupant density, lighting loads, equipment heat generation, operating hours, and ventilation requirements. These assumptions determine everything from rooftop unit capacity to duct sizing and airflow distribution. But over time spaces and needs change.

In Houston, commercial cooling systems transition from intermittent operation to sustained load within weeks. As temperatures rise and humidity increases, rooftop units move from moderate cycling to extended run times with little recovery window. Systems that have not been evaluated prior to peak demand experience higher failure rates, increased energy consumption, and accelerated equipment wear. Our pre-season commercial evaluations are designed to identify issues before p
