This well-established commercial HVAC service business offers an exceptional opportunity for a technician, operator, or strategic buyer seeking a stable, contract-driven revenue stream with strong growth potential. The company specializes strictly in service, maintenance, and repairs—no construction, installation, or general contracting work—making it an ideal turnkey operation with consistent workload and predictable income. The business maintains 47 signed commercial HVAC maintenance contracts, representing nearly 100% of its customer base. Approximately 98% of contracts renew quarterly, providing reliable recurring revenue. Clients include a diverse mix of retail locations, medical clinics, professional offices, financial service providers, specialty fitness studios, hardware stores, logistics drop-off centers, real estate offices, and multiple well-known property management firms. Many of these relationships involve multiple properties, giving the buyer a strong and stable foundation for long-term growth. The owner personally performs all inspections, service calls, diagnostics, and repairs on a wide range of rooftop gas pack units—equipment that is generally simple and efficient to service or replace. A high percentage of units across the portfolio are approaching replacement age, creating a significant untapped opportunity for a buyer who offers equipment installation services. This alone presents a major revenue upside. 2025 revenue is projected at approximately $175,000, with assets valued between $25,000 and $30,000, including a well-equipped commercial work van in excellent condition (with racking, ladders, tools, parts, and accessories). A second serviced van is also available if desired. This is a rare chance to acquire a compact, efficient, contract-heavy commercial HVAC service company with strong customer loyalty, recurring revenue, and immediate expansion potential—perfect for an owner-operator or an HVAC company seeking to add a service division or expand its client base.
