BIMS: A Legacy of Excellence

BIMS has been dedicated to heating, cooling, and mechanical services since 1980. The company was founded by HVAC contractor Randy Bellomy. He launched the business with just $200, an old truck, and a determination to do things the right way. Working out of his home, Randy built his reputation on a simple promise:

"If it heats or cools, we’ll work on it."

For decades, BIMS provided residential, commercial, and industrial HVAC-R services under that philosophy. Eventually, Randy’s son, Grant Bellomy, recognized that the industry and customer needs were changing. Grant grew up in the business. He spent his childhood around service trucks, tools, and rooftops. As he got older, he began imagining new ways to expand and modernize the company.

In 2018, after purchasing the business from his father, Grant led a major transformation. BIMS shifted its focus toward commercial and industrial HVAC-R—larger, more complex systems that demand advanced technical knowledge. Along with this evolution came a fresh identity:.

BIMS—Bellomy Industries & Mechanical Services—is a name that better reflects the company’s mechanical expertise and capability to support large-scale, mission-critical facilities.

Today, Grant’s vision is fully realized. BIMS is a trusted, highly specialized mechanical contractor serving the DFW region. Our technicians bring decades of hands-on experience. They hold Texas Air Conditioning Contractors Licenses (TACLs), ensuring every project meets the highest professional and regulatory standards.

From humble beginnings to a respected leader in advanced HVAC-R solutions, BIMS continues to honor its roots. The company embraces innovation—keeping businesses comfortable, productive, and running at their best.

    On time, very professional. Price is very reasonable. They have earned my business for all my company needs. The service is excellent and can't be beat. I have used other companies for my business and none compare to the skill and professionalism of BIMS.

  • Joe S.

    The chiller was having constant issues and shutting off, another company made repairs, but it still was shutting off. We called BIMS out and he found it just needed the coils cleaned and refrigerant adjusted on it. It's been working better and actually staying on now.

  • Stephanie W.

    I am not someone who usually posts reviews. But I can't say enough about Grant Bellamy. He arrived on time, he was courteous, and professional. He made sure that he explained the issues so that a layman like myself could understand. Mr. Grant runs his business with integrity and professionalism you don't see anymore. I will be using his services in the future and I would recommend him and BIMS to anyone.

  • Kevin S.

    We’ve partnered with Grant and his team at BIMS on numerous chiller and refrigeration projects, and they consistently deliver top-notch service. Their team—from ownership to office staff to technicians—is professional, knowledgeable, and incredibly reliable. Every job is handled with care and completed on time. It’s rare to find a company that combines technical expertise with such a strong commitment to customer service. Highly recommend working with them!
