Commercial air conditioning units have progressed from the very primitive split systems of the past to intelligent rooftop units capable of monitoring and diagnosing their own commercial air conditioning repair problems. Rooftop units also have much more insulation installed on their interior walls and ductwork then the commercial air conditioning units of just twenty years ago. Taken as a whole, the added insulation of duct systems, panels, and sealing techniques of commercial AC systems, make them much more suited for outside installation sites where energy concerns are important. These newer systems have a great advantage in both energy savings and on-board intelligence, however, this also requires a trained repair technician familiar with the latest advances in commercial AC repair procedures. Call us for your commercial air conditioning rooftop, split system, ductwork, or refrigeration needs.
