TDI Refrigeration

TDI Refrigeration operates from Rancho Cucamonga, California, delivering around-the-clock HVAC and refrigeration services to residential and commercial clients across the Inland Empire. The company maintains 24-hour emergency availability, ensuring technicians respond whenever heating or cooling systems fail. With a rating of 4.2 stars from 10 customer reviews, TDI serves a broad client base requiring everything from routine maintenance to complex industrial refrigeration repairs. The business specializes in both commercial HVAC installations and industrial refrigeration systems, positioning itself as a versatile contractor capable of handling diverse climate control challenges typical of Southern California properties.

What distinguishes TDI Refrigeration from standard HVAC contractors is their dual focus on industrial refrigeration and commercial HVAC systems, a combination rarely found in residential-focused markets. Their service portfolio includes vibration analysis and engineering capabilities, indicating technical sophistication beyond typical repair work. The company offers preventative maintenance programs designed to extend equipment lifespan and reduce emergency breakdowns. This engineering-forward approach suggests a contractor that prioritizes systematic problem-solving over quick fixes, appealing to property managers and business owners who value technical rigor over expedited service calls.

Customer experiences with TDI reveal a mixed but informative service record. Warren Hino describes a persistent refrigerant leak that resisted standard detection methods before technicians eventually identified a solution that held for many years, demonstrating persistence on complex problems. Shawn Whitfield notes the company's generous community involvement, highlighting corporate responsibility beyond service transactions. However, Timothy Dornaus recounts a three-visit fuse issue where the root cause went unidentified until a third appointment, raising concerns about initial diagnostic thoroughness and follow-through on customer communication. These varied experiences suggest a contractor with technical capability but inconsistent execution on straightforward repairs.
