Holohan Heating & Sheet Metal

What Holohan Heating & Sheet Metal does

Holohan Heating & Sheet Metal is a privately held, family-owned mechanical contractor founded in 1955, headquartered in Kankakee, Illinois, and serving the Chicago South Suburban region. The company provides commercial and industrial HVAC, plumbing, refrigeration, energy management, and custom sheet metal fabrication services to facility managers, building owners, and commercial operators. Its customer base spans two primary verticals — commercial and industrial businesses (offices, warehouses, manufacturing facilities, industrial plants) and food service and hospitality (restaurants, commercial kitchens) — and it operates as a factory-authorized dealer for leading HVAC and controls brands including Carrier, York, Trane, Honeywell, and Johnson Controls.

The company's service portfolio includes HVAC design and build, ductless split systems, refrigeration and food service equipment, energy management and controls (pneumatic, electric, and electronic), boilers and water heaters, plumbing and piping systems, infra-red radiant heaters, equipment rentals, pre-season preventative maintenance, and OEM parts supply. A distinguishing capability is the in-house custom sheet metal fabrication shop equipped with plasma cutting, MIG/TIG/stick welding, and flame cutting across stainless steel, aluminum, copper, and galvanized metal. The fabrication shop serves industrial (machine guards, smokestacks, tanks, conveyor beds), commercial (HVAC ductwork, kitchen exhaust, stainless countertops and cladding), and architectural (custom awnings, flashing, copper gutters, Pac-Clad colored metal) applications. The company also holds Illinois CCCD certification for backflow prevention testing, a regulatory-required annual service for commercial customers.

Revenue is generated primarily through professional services (HVAC service and installation, plumbing, controls), hardware sales (custom sheet metal, parts), and usage-based rental fees (portable A/C units, jet heaters, electric furnaces). Pricing is quote-based and not publicly disclosed, with rebate incentives up to $650 available through utility partnerships with NiCor, ComEd, and NISMACNA & LU 265. The go-to-market is entirely direct-to-consumer via phone and email — no e-commerce, online ordering, or self-service channels exist, and field service technicians and installation crews perform all work on-site at customer facilities. The company employs 13 people across service, installation, plumbing, pipefitting, and fabrication roles, operating from a single headquarters with no subsidiaries, no public listing, and no disclosed institutional ownership.

• APi Group: Public safety and specialty services conglomerate with a mechanical services segment serving commercial and industrial clients. Comparable to Holohan as a provider of HVAC and mechanical contracting services, though embedded within a much larger diversified portfolio.
• Johnson Controls: Public HVAC controls and building management systems OEM; Holohan is a factory-authorized dealer for Johnson Controls and York-brand equipment. Comparable as a brand partner and controls provider in the same HVAC value chain.
• Carrier Global: Public HVAC equipment manufacturer and one of Holohan's core factory-authorized brand partners for commercial HVAC equipment. Comparable as a major HVAC value-chain participant, though Carrier manufactures while Holohan sells, installs, and services its equipment.
• Trane Technologies: Public HVAC equipment manufacturer and Holohan factory-authorized brand partner for commercial and industrial HVAC systems. Comparable as a major HVAC OEM in the same value chain as Holohan's installation and service business.
• Lennox International: Public HVAC equipment manufacturer serving residential and light commercial markets. Comparable to Holohan as an HVAC industry participant in the same equipment ecosystem, though operating at the manufacturer level rather than as a contractor.
• Comfort Systems USA: Largest publicly traded mechanical contractor in the US, providing HVAC, plumbing, and piping services to commercial and industrial customers nationwide. Highly comparable to Holohan as a multi-trade mechanical contractor serving commercial/industrial clients, though operating at vastly greater scale, geographic reach, and with institutional ownership.
• EMCOR Group: Largest publicly traded mechanical and electrical services contractor in the US, serving commercial, industrial, utility, and institutional customers. Comparable to Holohan as a full-service mechanical contractor, but operating at vastly greater scale with national footprint and broader trade capabilities.

Direct peers

• Limbach Holdings: Public mechanical contractor specializing in HVAC, plumbing, and building controls for commercial and institutional customers across multiple US regions. Closely comparable to Holohan as an integrated mechanical contractor with in-house engineering, installation, and service capabilities—essentially a publicly-traded scaled version of the same business model.
• Service Logic: Commercial HVAC services company providing maintenance, repair, retrofit, and replacement services to industrial and commercial customers across multiple US regions. Comparable to Holohan as a commercial HVAC services provider focused on recurring service contracts and emergency response.

Others
