O’Callaghan Refrigeration is a division of O’Callaghan Heating and Air, Inc. Our Commercial Refrigeration division provides refrigeration services for restaurants, hotels, convenient stores, and any other commercial establishments.

Our philosophy has always been about honesty, integrity, reliability. Our success attributes to the professionally trained and experienced technicians, coupled with the office staff and management. The growth and success is tied to top-quality, on-time, and competitive service and installation.
All of our certified technicians receive continuous manufacturer training paired with customer service skills training. We only use OEM parts on all refrigeration equipment repairs, ensuring all repairs comply with manufacturer warranty guidelines.

Due to the overwhelming negligence of equipment not being properly maintained, manufacturers are now holding customers liable for repair cost. Our preventative maintenance program reduces the day-to-day stress on major components, thus prolonging the lifespan of the equipment and minimizing down-time. This equates to savings, GUARANTEED!
