About
McIntosh Corporation is an Oklahoma City-based full-service commercial mechanical contractor, founded in 1957, serving office buildings, healthcare facilities, industrial warehouses, educational institutions, government buildings, and mixed-use properties within a 25-mile radius of its South Eastern Ave location.
The company's scope goes well beyond routine HVAC service. McIntosh handles design-build projects, BIM and CAD coordination, commissioning, test and balance, fabrication, industrial process piping, and plumbing — with in-house design teams that manage projects from conceptual design through completion. This integrated approach means facility managers can engage a single contractor for new construction, renovations, retrofits, and ongoing preventive maintenance.
McIntosh is a unionized mechanical contractor, and its professional affiliations include ASHRAE, ASME, NEBB, SMACNA, TABB, IGSHPA, USGBC, and several others — organizations in which the company holds active, leadership-level roles rather than nominal membership. That involvement keeps its technicians current on evolving codes, performance standards, and sustainability practices relevant to Oklahoma's commercial market.
For ongoing reliability, McIntosh offers structured preventive maintenance agreements and 24/7 technician availability, covering systems that include rooftop units, air handling units, chilled water and chiller systems, boiler systems, heat pumps, and geothermal systems. Multi-site property managers benefit from the company's capacity to coordinate service across multiple locations under a single service agreement.
