Commercial AC and Heating Installation

The load requirements for commercial buildings differ dramatically from residential dwellings due to varying occupancy rates and generated heat. The design experts at McWilliams understand the importance of engineering your commercial HVAC system to provide sufficient capacity in all weather conditions. As your new equipment is installed, we’re mindful of maintaining a strict construction schedule. Our technicians pay particular attention to the design and installation of the ductwork, so the proper amount of conditioned air is delivered to each room in the building.

Refrigeration, Ice Machines & Coolers

Companies in the food preparation and storage business rely on their commercial refrigeration appliances to keep vital inventory fresh. In particular, the foodservice industry is highly dependent on properly functioning commercial refrigerators, cool rooms, ice makers, freezers and beer systems. Wherever food and beverages are stored, rigid specifications for temperature and humidity fluctuations must be maintained. A breakdown in a refrigeration unit can immediately impact sales and operational continuity. Our qualified techs have the knowledge and training required to address service and repair issues for virtually every brand of commercial refrigeration equipment.
