What We Install
Commercial HVAC Systems We Install
We install and service the full range of commercial heating and cooling equipment, with each system chosen for the building it serves.
-
-
Commercial Boilers
Hydronic and radiant heating systems for buildings that run on hot water rather than warm air.
-
Rooftop Units (RTUs)
Packaged rooftop heating and cooling, the space-efficient standard for flat-roof commercial buildings.
-
Commercial Air Conditioning
Cooling systems that keep staff and customers comfortable through a Northern Ontario summer.
Commercial HVAC covers more than a single box on the roof. We install commercial furnaces, boilers, rooftop units, and air conditioning systems, and we handle the sheet metal fabrication and custom ductwork that ties them together. It is one part of the broader HVAC and mechanical services we provide across the region.
We recommend and install LG, Navien, Continental, and Napoleon, with budget alternatives available when project requirements call for them. Every recommendation is based on building size, occupancy, and the heating and cooling load, not a one-size-fits-all package. For buildings weighing their options, we also fit cold-climate heat pump installations and commercial air conditioning systems alongside traditional heating equipment.
Rooftop Units
Rooftop Unit Installation & Service in Timmins
A rooftop unit, or RTU, is a packaged HVAC system that sits on the roof and handles heating and cooling from one cabinet. RTUs suit commercial buildings because they free up interior space and centralize the equipment where it is easy to service, which is why they are the standard on the flat-roof buildings common across Timmins.
Installation is a coordinated job. We start with a site assessment and a structural evaluation to confirm the roof can carry the unit, then coordinate crane and rigging to set it in place. From there we make the electrical and gas connections, integrate the ductwork, and finish with startup and commissioning so the unit runs right from day one.
Ongoing service keeps an RTU efficient and prevents the breakdown that shuts a business down. We handle routine maintenance and emergency RTU repair when a unit quits, so a failure does not turn into days of lost operation.

Heating
Commercial Furnace & Boiler Installation
Commercial furnaces deliver forced-air heating for offices, retail spaces, and light industrial buildings. Commercial boilers handle hydronic and radiant applications, moving heat through water for buildings designed around that approach. We install and service both, and we help you choose the right one for how your building is built and used.
Sizing is where a commercial heating job is won or lost. We work from BTU requirements, the building envelope, insulation levels, and occupancy patterns rather than a rough estimate, because equipment matched to the load runs efficiently and lasts longer. We install gas and propane systems to suit the fuel available at your site.
Northern Ontario winters demand heating equipment that is properly sized and genuinely reliable, and 20+ years of trade experience in commercial heating is what stands behind that. The same care applies to smaller jobs, including residential furnace installation across the region.
Ductwork
Commercial Ductwork Design & Fabrication
Ironclad fabricates and installs custom sheet metal ductwork for commercial projects. Proper ductwork is critical: it decides how evenly a system heats and cools, how quietly it runs, and how much it costs to operate. A poorly designed duct system undermines even the best equipment.
Our design accounts for airflow balance, static pressure, noise control, and energy efficiency, and we finish the work with duct sealing, insulation, and damper installation. That specialized ductwork experience extends to demanding jobs like dust collector maintenance for school boards , where clean, balanced air handling really matters.
- Airflow balance across every zone
- Static pressure kept within design limits
- Noise control for occupied spaces
- Energy efficiency through tight, sealed runs
- Duct sealing, insulation, and damper installation

The Process
Commercial HVAC Installation Process
Every commercial project follows the same clear sequence, from the first site visit to a commissioned system that performs.
-
Site assessment and load calculation
We evaluate building size, insulation, occupancy, and existing systems to size the equipment correctly.
-
System design and equipment selection
We recommend appropriate equipment based on your heating and cooling loads and your budget.
-
Proposal and timeline
You receive a detailed quote covering equipment specifications, labour, and the project schedule.
-
Installation coordination
We schedule work to minimize business disruption and coordinate with other trades when needed.
-
Startup, testing, and commissioning
We verify system performance, train your staff on operation, and provide documentation.
Most commercial clients decide within a week, depending on urgency and project scope. We keep the path to that decision simple: a clear assessment, an honest recommendation, and a detailed proposal you can act on without chasing details later.
One accountable team carries the work from design through commissioning, so the people who sized your system are the ones who install and start it up. That keeps quality consistent and leaves you with documentation and a crew you can call.
Emergency Service
Emergency Commercial HVAC Service
When a commercial system fails, we answer. Heating failures in a Northern Ontario winter can shut down operations and create real safety risks, so commercial breakdowns cannot wait for the next business day.
We handle the usual emergencies: furnace failures, boiler shutdowns, RTU malfunctions, and frozen pipes. Our team runs two service trucks for responsive coverage across the region. Call (705) 221-0677 for emergencies, Monday to Friday.
