Controlled Air

What Controlled Air does

Controlled Air, Inc. is a privately held commercial HVAC design-build and energy solutions provider headquartered in Branford, Connecticut, founded in 1980 and acquired by Yanmar America in October 2022. The company delivers integrated engineering, in-house sheet metal fabrication, controls, and installation services for large and small commercial facilities across Connecticut, Rhode Island, Massachusetts, and parts of New York, operating under the Yanmar Energy Systems North America (YESNA) umbrella since April 2026 alongside Yanmar Energy Systems and TEDOM. Its core technology stack spans conventional HVAC systems, building automation (authorized specialist for Johnson Controls and ABB), Combined Heat & Power (CHP/cogeneration), Yanmar Gas Engine Heat Pumps (GHP), microgrids integrating solar and batteries, and a proprietary Agile Facility Management (AFM) energy evaluation program combining AI analytics with human expert analysis.

The business operates a project-based design-build model supplemented by recurring service and maintenance contracts, 24/7 emergency service, and energy evaluation/consulting services. Revenue is generated through custom-quoted design-build projects (typically $500K–$1M+), custom preventive maintenance contracts, building automation and controls installations, and equipment sales/distribution of Yanmar-branded products (GHP, CHP, rooftop units), TEDOM cogeneration, Schuco Solar, and PortaFab cleanroom enclosures. Go-to-market is direct enterprise field sales via dedicated sales engineers and project managers, with no residential or channel/reseller exposure beyond the Yanmar distribution network.

Customer segments span healthcare, entertainment/performance venues, government/municipal, manufacturing/industrial, and educational institutions, with a LEED-accredited and Connecticut/Rhode Island-licensed workforce. The company maintains a notable project portfolio including the Rhode Island Surgical Facility, Capitol Theatre NYC chiller retrofit, Community Hospital operating room retrofit, Gaylord Hospital gas conversion, 55 Farmington Ave state building DDC upgrade ($43,820 annual savings), Long Wharf Theatre ($500K project, $25K CL&P incentives), The Maritime Aquarium CHP installation, and turnkey Yanmar warehouse deployments. Operational depth is reinforced by long-tenured employees (20+ years), multiple Chiocchio family members across three generations, and recent capacity additions including a new fabrication warehouse and dedicated outbound sales hiring.

Direct peers

• Limbach Holdings: Public mechanical contractor specializing in design-build HVAC, plumbing, and controls for complex commercial and institutional facilities. Closest publicly traded peer given similar design-build delivery model and focus on integrated mechanical and controls work.

Broad incumbents

• EMCOR Group: Largest publicly traded provider of mechanical and electrical construction, energy, and facilities services in the U.S. Overlaps with Controlled Air across commercial HVAC design-build, controls, and energy services, but at vastly greater scale and national footprint.
• Comfort Systems USA: National commercial HVAC mechanical contractor with design-build and service offerings across all major U.S. metros. Comparable customer segments (commercial, healthcare, industrial) and integrated mechanical + controls delivery model.
• APi Group: Global life safety, specialty, and industrial services holding company with significant mechanical/HVAC installation and service exposure. Comparable integrated service model and recurring maintenance revenue, but broader portfolio.
• Johnson Controls International: Building automation and HVAC controls giant whose authorized specialist network includes Controlled Air. Overlaps with Controlled Air's controls and energy services business, including BMS solutions and Energy Star program association.
• Trane Technologies: Global HVAC equipment manufacturer with extensive commercial service, controls, and building solutions arm. Comparable on commercial HVAC, building automation, and energy services, though Controlled Air is an installer/customer rather than an OEM competitor.
• Carrier Global: Major HVAC OEM including Carrier HAP software and a North American commercial service network. Comparable on energy modeling tooling and large-scale commercial HVAC, though Controlled Air is primarily an installer/customer of Carrier products.

Others

• Hubbell Incorporated: Electrical and communications products manufacturer with growing HVAC-adjacent controls and electrification exposure. Related through commercial building systems and ABB-type control ecosystems; not a direct HVAC service competitor.
• AAON: Commercial HVAC equipment manufacturer specializing in high-efficiency RTUs, air handlers, and energy recovery equipment used in retrofit projects. Comparable on equipment specification side for the commercial retrofit market Controlled Air serves.

Emerging players

• Modine Manufacturing: Manufacturer of commercial and industrial HVAC, refrigeration, and heat-transfer equipment used in data center, commercial, and cleanroom environments. Overlaps with Controlled Air's cleanroom, pharma, and high-efficiency HVAC work but from a manufacturing perspective.
