Products and services

• Wall-mounted heat pumps (Thermopompes murales) Ductless wall-mounted heat pump units that provide heating, cooling, and dehumidification for residential spaces without central ductwork, designed for cold-climate operation; installation and sales offered across Quebec.
• Central heat pumps (Thermopompes centrales) Central heat pump systems that distribute conditioned air throughout entire buildings via duct networks, providing uniform comfort across multiple rooms with air balancing performed by certified technicians; available with Hydro-Québec LogisVert subsidy eligibility.
• Integrated HVAC-R system services (heating, ventilation, air conditioning, refrigeration) Complete end-to-end HVAC-R service including design, installation, maintenance, and repair for residential, commercial, and industrial clients across four Quebec branches, including heat pumps, ventilation, refrigeration, and geothermal systems.
• Commercial and industrial refrigeration systems Installation, maintenance, and 24/7 emergency repair of cold rooms, display cases, refrigerated counters, industrial chillers, and freezers for food retail, food processing, pharmaceutical, and manufacturing sectors.
• Air exchangers — VRC (HRV) and VRE (ERV) systems Heat Recovery Ventilators (VRC) that recover heat from exhaust air, and Energy Recovery Ventilators (VRE) that recover both heat and humidity, used in new construction and renovations to maintain indoor air quality in sealed, energy-efficient homes.
• Heat accumulators (Accumulateurs de chaleur) Electric central heating systems (e.g., Steffes Serenity models) that store thermal energy in high-density ceramic bricks and release it gradually, integrating with existing duct systems and optionally paired with heat pumps; eligible for up to CAD $15,000 in Hydro-Québec LogisVert subsidies.
• Geothermal heating and cooling systems (Systèmes de géothermie) Ground-source heat pump systems that extract thermal energy from the ground through vertical or horizontal loop circuits, leveraging stable subsurface temperatures for efficient heating in winter and cooling in summer.
• Humidification and dehumidification systems Commercial and industrial systems that control indoor humidity levels to protect equipment, prevent mold, stabilize materials, and maintain occupant comfort across various building types and processes.
• Preventive and predictive maintenance programs Scheduled inspections, cleaning, adjustments, and performance testing of HVAC-R systems to reduce operational costs, prevent premature wear, and avoid unplanned shutdowns across residential, commercial, and industrial customers.
• Custom HVAC-R engineering services Custom HVAC-R engineering and design-build for commercial and industrial projects, including system design, installation, and optimization for specialized industrial applications such as chocolate production cooling systems.

Broad incumbents

• Johnson Controls (York): Global building-controls and HVAC-R company (York brand) with extensive Canadian commercial and industrial service operations. Comparable in commercial HVAC-R installation, controls, and service-contract model; operates at much larger scale.
• Plan Group Inc. Canadian mechanical and electrical contractor with strong presence in Ontario and Quebec. Overlaps with LeProhon on commercial HVAC-R installation, building automation, and industrial/engineering work.
• Black & McDonald: Canadian multi-trade mechanical, electrical, and HVAC-R service contractor operating nationally with service-contract and 24/7 maintenance offerings. Closely comparable to LeProhon on commercial/industrial HVAC-R service model, though at multi-region scale.
• Ainsworth Inc. Canadian mechanical and HVAC-R contractor serving commercial, institutional, and industrial clients across multiple provinces. Comparable to LeProhon in industrial/engineering HVAC-R project delivery and service-contract model.
• Carrier Global Corporation: Multinational HVAC, refrigeration, and building-controls company with deep Canadian presence through Carrier dealers. Competes with LeProhon in commercial refrigeration, light-commercial HVAC, and controls, but operates at vastly larger scale and serves multiple geographies.
• Reliance Home Comfort: Large Ontario-based residential heating, cooling, and water-heating service provider. Comparable to LeProhon's residential HVAC install/maintenance motion and recurring-service revenue model, though Reliance does not materially serve Quebec or industrial segments.
• Lennox International: US-headquartered HVAC manufacturer (residential and commercial) with Canadian distribution through independent dealers. Overlaps with LeProhon's residential heat-pump, central-system, and light-commercial service lines via dealer/installer networks.
• BGIS: Canadian integrated facilities-management company that delivers HVAC-R maintenance, mechanical services, and energy programs to commercial/industrial clients. Overlaps directly with LeProhon's commercial/industrial maintenance and 24/7 service offering.
• Enercare Inc. Canadian residential HVAC, water-heater, and home-services provider with subscription/maintenance offerings. Closest publicly visible analog to LeProhon's residential heating-and-cooling service-plus-maintenance model, although Enercare is broader-geography and residential-focused.
• Trane Technologies: Global HVAC manufacturer and service provider with a significant Canadian commercial/institutional footprint. Compares to LeProhon as a much larger incumbent offering HVAC equipment, installation, and service across overlapping customer segments (commercial, industrial, light residential).
