Service & Maintenance

Callahan Mechanical's Service Division focuses on three basic principles for providing exceptional service:

HONESTY     •     INNOVATION     •     SAFETY

Standing behind these principles, we deliver honest, dependable and professional service 24/7. We strive to establish a solid relationship from the very first service call or building site survey, and serve a wide range of customers - from small commercial strip centers to large industrial manufacturing plants, and everything in between.

Our skilled technicians regularly attend factory training and certification from all major manufacturers of HVAC equipment, enabling us to continue to find innovative solutions to meet our customers' needs. Additionally, our technicians are efficiently dispatched using the latest GPS technology in conjunction with computer dispatching software. 

Safety and environmental responsibility are also top priorities. We use biodegradable cleaning products and utilize a refrigerant tracking program to limit refrigerant leaks which would adversely impact the environment.
