Founded in 1918 by Daniel Hayes in Chicago, Hayes Mechanical LLC began as a small boiler repair company, rooted in principles of honesty and integrity. Over the decades, the family-owned business has evolved into a prominent full-service mechanical contractor, operating across ten states. The company expanded its offerings to include commercial and industrial HVAC services, plumbing, and specialized fabrication of boilers and pressure vessels.
From its humble beginnings during challenging economic periods such as the Great Depression and World Wars, where payments were sometimes accepted in trade, Hayes Mechanical has consistently prioritized quality care and customer satisfaction. After transitioning ownership through several generations, the Mooney family took the reins and navigated the company towards modernization and broader service capabilities. The firm actively offers 24/7 service, ensuring clients receive timely assistance year-round.
Today, with a workforce of trained and experienced professionals including Boilermakers, Pipefitters, HVAC technicians, and Millwrights, Hayes Mechanical is well-positioned to handle complex mechanical systems for both industrial and commercial sectors. Its reputation is built not only on the technical expertise of its employees but also on longstanding relationships with trade unions, underscoring its commitment to quality workmanship.
Headquartered at a sprawling facility in Chicago, the company continues to embrace innovation, strategically expanding operations and services to meet the growing demands of its clients. The vision remains clear: while striving for operational excellence, Hayes Mechanical aspires to maintain its status as a trusted name in the mechanical contracting industry, with a focus on delivering the best solutions rather than merely aiming to be the largest provider.
