Telecom Tower HVAC Service Contractor, 24-Year Michigan Operation

Full Editorial Writeup

This is a 24-year-old HVAC maintenance and repair contractor based in Davison, Michigan (the listing header says Detroit but operations are in Genesee County). The company holds an exclusive contract with a major national telecom carrier to maintain climate control systems across 2,100-plus cell tower sites throughout Michigan. The entire business runs on this one contractual relationship, which means zero marketing spend and no customer acquisition cost, but also a single point of concentration risk that will define the whole diligence process.

The operation is fully licensed and certified, carrying a Michigan Licensed Mechanical Contractor license, a Licensed Building Contractor license, plus EPA Universal, HVAC/R, R-410A, and R-22 certifications. A stable crew of seven full-time employees is expected to stay post-sale, which matters enormously because the contract performance depends on them, not the departing owner. The sale includes a 2,400 square foot owned building valued at $400,000 inside the $2.2M asking price.

At $1.7M revenue and $633K cash flow, this is a high-margin recurring-service operation (roughly 37 percent cash flow margin) built around mission-critical infrastructure. Cell towers must stay cooled regardless of the economy, so the demand is genuinely non-discretionary. The headline opportunity is the national vendor status with the carrier, which theoretically opens multi-state expansion, but that is upside, not something to pay for today.
