What Encon does

Encon Heating & AC is a full-service mechanical HVAC contractor founded in 1969 and headquartered in Stratford, Connecticut. The company delivers design-build, installation, repair, and maintenance services for both high-end residential and commercial customers across Connecticut, New York, New Jersey, Massachusetts, and Rhode Island, supported by a fleet of 190 service vehicles and approximately 320 employees dispatched from offices in Stratford, Stamford, Nanuet, and Mount Kisco. Its commercial practice serves institutional and enterprise clients across healthcare (Yale-New Haven Hospital, multiple CT hospital systems), higher education (Yale, Fairfield, Sacred Heart), data centers (Priceline, AQR, Factset), media (NBC Universal Stamford), government (GSA/DEA, municipal), hospitality (Marriott, country clubs), industrial (Bigelow Tea, Pez Candy), and aviation (Westchester County Airport), while the residential business serves individual homeowners with 24/7 emergency service and tiered maintenance plans.

The company's technical capability spans the full mechanical stack — furnaces, boilers, radiant floor, geothermal heat pumps, central AC, ductless mini-splits, chillers, ventilation, building automation and direct digital controls, sheet metal fabrication, and energy solutions including solar PV — with in-house custom ductwork fabrication, an ENCON University training program featuring a 2,000 sq ft technical lab, and the proprietary ThermaClear oil-fouling remediation product (approved by ASHRAE, UL Solutions, and ASTM International). Its core delivery methodology is the ENCON Edge 7-step design-build process that provides single-point accountability from consultation through commissioning and ongoing service, differentiating it from installation-only contractors.

Encon operates as a private, for-profit mechanical services business and is part of the Service Logic nationwide contractor network. Revenue is generated through project-based commercial HVAC construction and replacement work, recurring residential and commercial maintenance contracts (Gold and Platinum plans), one-time repair and installation jobs, energy consulting and efficiency upgrades (often financed via C-PACE, PPA, or SBEA programs), and ThermaClear product applications. GTM motion is hybrid: enterprise field sales with dedicated project managers for commercial accounts, and direct-to-consumer with online booking, a ServiceTitan-powered customer portal, and a dedicated Customer Service Manager per location for residential customers. Recent inorganic expansion includes the 2025 acquisitions of Controlled Temperatures (Fairfield County) and Blend Air Mechanical (Rockland/Westchester/Bergen Counties), the latter adding plumbing services to the platform.

Direct peers

• Hiller Plumbing, Heating, Cooling & Electrical: Multi-trade residential and light-commercial HVAC, plumbing, and electrical contractor operating across Tennessee and the Southeast. Directly comparable to ENCON in service mix (heating, cooling, plumbing), customer base (homeowners + small commercial), and recurring maintenance model.
• Horizon Services: Regional residential HVAC, plumbing, and electrical services company serving the Mid-Atlantic (Delaware, Pennsylvania, Maryland). Closely comparable to ENCON in dual residential/commercial focus, 24/7 emergency service, and maintenance plan structure, though geographically distinct.

Broad incumbents

• CoolSys (CoolerX): Large national commercial refrigeration and HVAC services platform with national footprint. Comparable to ENCON's commercial HVAC work at scale, but operates as a multi-region platform rather than regional specialist.
• EMCOR Group: Public, large-scale mechanical and electrical construction, energy, and facilities services provider. Comparable in commercial HVAC/MEP contracting and design-build capabilities, but with multi-billion-dollar scale and national reach that dwarfs ENCON.
• APi Group: Public safety, security, and specialty services conglomerate with mechanical services exposure. Overlaps with ENCON in commercial HVAC/mechanical contracting, but APi is a multi-thousand employee public platform with diversified service lines.
• HomeServe USA: National home services and repair plan provider with HVAC, plumbing, and electrical coverage. Comparable to ENCON's residential maintenance plan approach at scale, though HomeServe primarily operates a membership/affiliate network model rather than direct service delivery.
• Authority Brands: Multi-brand residential home services franchisor with HVAC, plumbing, and electrical brands. Comparable to ENCON's residential service motion, though Authority Brands operates through franchisees rather than employee technicians.
• Petro Home Services: National home services platform offering HVAC, plumbing, and electrical across multiple states. Comparable to ENCON in dual residential/commercial focus and service plan economics, but at significantly larger geographic scale.

Others

• Carrier Enterprise (Distributor): HVAC equipment distributor and service provider across the Southeast and Mid-Atlantic. Comparable to ENCON as a Carrier-affiliated service provider, though Carrier Enterprise operates primarily as a distributor with attached service capabilities rather than a pure HVAC contractor.
• Carrier Global: Public global HVAC OEM and service provider. Comparable to ENCON through Carrier training partnership and equipment sourcing, but at vastly different scale and operating model (manufacturer vs. contractor).
