Commercial Service: Bloomington IN's Trusted HVAC and Plumbing Partner Since 1946

For homeowners and businesses in Bloomington and across Indiana, Commercial Service is the name families and companies rely on for heating, cooling, and plumbing. Starting as a small two-man operation in 1946, they've grown into one of the state's largest Residential Trane Dealers and a full-service provider. Whether it's a furnace failing in a Martinsville winter or an AC unit struggling in a Seymour summer, their team is ready to help. They offer emergency service and have over 30 full-time employees dedicated to both residential and commercial projects.

A Legacy of Growth in Bloomington

Joe Hamros founded Commercial Service of Bloomington, Inc. in 1946 to fix heaters. The company grew steadily. In 1973, Jules Sonneborn purchased it. His son, Mike, joined in 1975 and helped build strong relationships with major commercial clients in the area. By the late 1990s, the company employed over 30 people and became a leading Trane dealer. A key milestone came in 2012 when they partnered with R&S Plumbing to offer complete plumbing services. After Mike Sonneborn's retirement in 2015, Scott Rink became President, with Charlie Laughlin leading residential operations.

Leadership Committed to Community

Charlie Laughlin, Vice President of Residential Operations, joined Commercial Service in 2007. He helped grow the residential side of the business. Charlie often says the company's success comes from its people, whom he considers family. This local, hands-on leadership ensures decisions are made with the customer in mind. The team is involved in the community, understanding what Bloomington IN residents and businesses need from their HVAC and plumbing providers.

What Makes Commercial Service Stand Out

• Expertise in Special Projects: They have unique experience with historical renovations and clean room designs for medical manufacturing.
• Full-System Capability: From boilers and chillers to radiant floor heat and DDC controls, they handle complex commercial systems alongside standard home services.
• Long-Term Manufacturer Partnership: As a prominent Residential Trane Dealer in Indiana, they offer trusted equipment and deep product knowledge.
• Dual-Trade Service: Their partnership with licensed R&S Plumbing means one call can solve both HVAC and plumbing issues.
