Our History

Randy Bellomy comes with 43 years experience in the HVAC-R industry, including several multi-million dollar projects. He started Bellomy Heating & Air, Inc. (BHA) back in 1980 with the motto "if it heats or cools, we work on it". We believe in giving the best quality job that returns the best value to a client.

In 2018, Grant Bellomy took over the company with a name change from Bellomy Heating & Air, Inc. to Bellomy IMS, Inc., ( which stands for Bellomy Industries & Mechanical Services, Inc.) or BIMS, Inc. for short, to better reflect what we do as a company.
