Commercial · Caledon, OntarioCommercial HVAC in Caledon
Commercial HVAC in Caledon covers three kinds of building: plazas and storefronts in Bolton with packaged rooftop units, warehouses and shops heated by unit heaters or infrared tube heaters, and rural businesses with no gas main, where the equipment runs on propane or electricity. We service, repair and replace all three, priced per site in writing after an assessment. One rule for owners: a rooftop unit past 15 years that needs a compressor or a heat exchanger should be priced for replacement before it is repaired.
Rooftop units, warehouse heat and rural commercial buildings across Caledon
Bolton is where most of Caledon's commercial roofs are. The retail plazas and the industrial and warehouse buildings reached from Highway 50 run packaged rooftop units on Enbridge natural gas, and those units fail on a known list. Belts and blower bearings wear, contactors and capacitors give out, economizer dampers seize open in winter, condensate pans plug, and heat exchangers crack on older units. A maintenance visit in spring and another in fall exists to find those faults before a tenant does.
Outside Bolton the questions change. A garden centre, an equestrian facility, a workshop or a country restaurant on a rural concession often has no gas main at the road, so the heating equipment has to be specified and set up for propane, and some rural sites have single-phase power only. That matters because larger rooftop units are built for three-phase service; on a single-phase site the choice narrows to smaller packaged units or split systems. We confirm the fuel, the Hydro One service and the panel capacity at the assessment, before anyone orders equipment.
Warehouses and shops are heated differently from offices. Gas-fired unit heaters and infrared tube heaters warm the floor and the people without trying to heat the whole volume of air, and their usual faults are igniters, flame sensors, blocked vents and failed fan motors. Gas work on any of it, natural gas or propane, is done by TSSA-licensed technicians to CSA B149.1, and electrical connections fall under ESA rules. Where a replacement or a new installation needs a building permit, it goes through Town of Caledon Building Services.
Distance is the honest part. Caledon is the far end of our service area from the Burlington shop, so a breakdown call here is a longer drive than one in Halton, and catching the worn belt and the pitted contactor in April is worth more to a Caledon operator than any promise about response. Contracts are priced per unit with a written condition report and photos for each one: see commercial maintenance contracts, rooftop unit service and warehouse and industrial HVAC. The overview is on the commercial HVAC page, our residential work in town is on the Caledon service area page, and you can request a site assessment.

Commercial in Caledon — FAQs
What does commercial HVAC service cost in Caledon?
Commercial work is priced per site, in writing, after we have seen the equipment, because one small unit over a storefront and a row of large units on a warehouse are different jobs. The number is driven by unit count and tonnage, roof access, the fuel, and for replacements whether a crane and a curb adapter are needed. The assessment itself produces a tagged list of every unit and its condition.
Can you service a rooftop unit or unit heater that runs on propane?
Yes. Many rural Caledon businesses have no natural gas main, and packaged rooftop units and unit heaters can be set up for propane with the manufacturer's conversion kit, the correct orifices and the gas pressure set to the propane specification. A TSSA-licensed gas technician does that work. If a main has since reached your road, we can also quote converting the equipment to natural gas.
Our building only has single-phase power. Can we still get a rooftop unit?
Often, yes, within limits. Smaller packaged units are made for single-phase service, while larger ones generally need three-phase. If the cooling load is bigger than a single-phase unit can carry, the usual answers are two smaller units, a split system, or a service upgrade arranged with Hydro One and an electrical contractor. We check the service and the panel first, so the equipment on the quote is equipment you can run.
How fast can you get to a commercial breakdown in Caledon?
You get a real window when you call, and it will be longer than for a business in Burlington or Oakville: the truck comes up the 407 and 410 to Highway 10, or by Highway 50 to Bolton. The emergency line is answered around the clock at the ordinary rate. For a site that cannot go down, scheduled maintenance and spare belts and filters kept on site do more than a promised arrival time.
Do we need a permit to replace a rooftop unit in Caledon?
It depends on the scope. A like-for-like replacement on the existing curb is a different job from a new unit, a change in capacity, new gas piping or structural work, and the Town of Caledon's Building Services decides what needs a permit. Raise it at the quote stage and have the answer before the crane is booked. Gas work follows TSSA rules and electrical connections follow ESA rules either way.
