Bellomy Industries & Mechanical Services - B.I.M.S., Inc

Bellomy Industries and Mechanical Services, commonly known as B.I.M.S., has operated in Grapevine since 1980 when founder Randy Bellomy launched the company with just $200 and aDetermination to do things the right way. Today, his son Grant Bellomy leads daily operations carrying forward that ethos across four decades of continuous service. The company holds strong ratings at 4.3 stars from 32 customer reviews, serving Grapevine homeowners alongside neighbors in Colleyville, Southlake, Flower Mound, and Carrollton. B.I.M.S. handles residential, commercial, and industrial heating, cooling, and refrigeration needs through a staffcombining decades of collective trade experience.

What distinguishes B.I.M.S. from broader-market competitors is their engineering analysis approach that often saves customers from unnecessary fullsystem replacements. Reviewers document how Grant and his team identified mismatched supporting equipment in a church auditorium chiller system,proposing a targeted fix that cost a fraction of the $750,000 replacement estimates the customer had received elsewhere. This problemsolving orientation extends across their commercial chiller and refrigeration project portfolio, where the company manages complex mechanical systems that require precise diagnostic skill rather than cookiecutter solutions. Technicians communicate clearly with property managers and homeowners alike, explaining technical findings before recommending repairs.

One reviewer with the South Main Church of Christ in Weatherford described how Grant arrived for consultation, assessed the aging chiller system, and recognized the core equipment remained viable despite multiple prior contractors recommending complete replacement. The team delivered a scoped repair that brought the system into proper operation without the massive capital expenditure expected. Homeowner Cody noted Grant handles preventive maintenance on both his current and previous residence, praising the technician's attention to detail and the office staff's communication consistency. For urgent situations requiring same-day response, reviewers describe the team's reliability in crisis scenarios.
