Best HVAC Toronto coordinates turnkey commercial RTU crane replacements across the Greater Toronto Area, with full swap pricing from $20,000 to $150,000 CAD depending on RTU tonnage and complexity. Our team handles every element of the project in sequence: site assessment, municipal road closure permits, crane rigging and lift, custom curb adaptor fabrication, gas piping reconnection to CSA B149.1, electrical disconnect and reconnect, TSSA commissioning and sign-off, and a complete written documentation package for property manager records. Most single-RTU replacements are completed in a single calendar day, with the crane demobilising the same afternoon the unit is commissioned. Call 647-254-4113 to reach our commercial team.
What does turnkey RTU crane replacement in Toronto include?
Commercial RTU crane replacement involves more logistics than most commercial HVAC work. The unit itself is the straightforward part: an end-of-life or unrepairable rooftop packaged unit is lifted off, and a replacement is set in its place. What makes the project complex is the coordination required around the lift: crane booking and rigging, road access and permits, curb geometry and adaptor fabrication, gas supply reconnection, electrical service, and TSSA commissioning. When these elements are split across multiple contractors, the scheduling gaps between them commonly extend a one-day project into two weeks of back-and-forth. Our team covers every element under one contract, eliminating those gaps entirely.
Property managers and facility operators handling multi-building portfolios benefit specifically from the single-contractor model. Rather than managing crane companies, permit agents, gas contractors, and electrical trades independently, your team deals with one written scope, one project timeline, and one documentation package at completion.
Mobile crane rigging and rooftop lift
Our team books and coordinates a mobile crane sized to the RTU tonnage and the site geometry. Street-side lifts, rear-access lifts over neighbouring structures, and multi-unit lifts across several buildings in a single mobilisation are all within scope. Our crew specifies rigging requirements and communicates safe working loads and lift points to the crane operator before mobilisation, reducing set-up time on the day of the lift.
Custom steel curb adaptors
Replacement RTU models from Carrier, Trane, Lennox, and York frequently have different footprint dimensions than the units they replace, particularly on buildings constructed before 2010. When the existing roof curb does not match the replacement unit’s base dimensions, our team fabricates a custom steel curb adaptor measured precisely to the existing opening and the new unit’s base. Fabrication is handled in-house, eliminating the two to four week delay that occurs when adaptors are ordered from a third-party fabricator and shipped to site.
Municipal road closure permits
Street-side crane operations in Toronto require a road closure permit from the City of Toronto. Our team applies for the permit as part of the project scope, factors the permit approval timeline into the overall project schedule, and sets up the required traffic control signage on crane day. Permit costs are itemised and included in the written project quote so there are no surprise additions at invoice time. Sites outside Toronto’s boundaries require permits from the relevant municipality; our team handles those applications as well.
Gas piping, electrical, and TSSA commissioning
Our TSSA G1/G2 certified technicians disconnect the gas supply before the crane lift, then reconnect and pressure-test the gas line after the new unit is secured on the curb. The gas commissioning includes a TSSA sign-off on the gas section of the packaged unit. Our crew handles the electrical disconnect before the lift and reconnects the electrical service and controls after the new unit is set, including thermostat setpoints, economiser damper calibration, and occupied and unoccupied scheduling. Property managers receive the equipment manufacturer’s warranty documentation alongside the commissioning report on the day of completion.
How does the single-day RTU crane replacement process work?
Single-day completion depends entirely on pre-planning. The crane day goes smoothly when the scope is fixed in advance, the permit is in hand, the replacement unit is staged on site or nearby, and the curb adaptor is ready to install before the crane arrives. Our process is designed to resolve all of those variables in the weeks before our crew arrives on the roof.
The site assessment visit establishes the existing curb dimensions, the crane access route, the gas supply pipe size and material, and the electrical service configuration. From that visit, we prepare the written scope and set the project timeline. Equipment is ordered, the curb adaptor is fabricated, and the permit application is submitted concurrently, so no phase waits on another. A crane date is not confirmed until all three are in hand.
On the crane day, the old unit comes off the curb, the adaptor is positioned and secured, the new unit is rigged and set, and our gas and electrical crew commissions the system while the crane is still on site. For most single-unit replacements, the crane demobilises and the building has a running, commissioned RTU before the end of the business day.
Which RTU brands does your crew replace?
Our team replaces and commissions Carrier WeatherMaker, Trane Voyager, Lennox Landmark, and York Sunline packaged rooftop units across Toronto and the GTA. These four brands represent the majority of the commercial RTU stock across Toronto’s retail, restaurant, and office buildings. For buildings with other brand installations, call to confirm commissioning familiarity and part availability before booking.
We size replacement units against the building’s current heating and cooling load rather than simply replacing like for like. Occupancy changes, kitchen exhaust modifications, and envelope upgrades since the original installation can shift the required tonnage meaningfully, and an undersized or oversized replacement causes the same comfort and efficiency problems as the failed unit it replaced.
What drives the cost of RTU crane replacement in Toronto?
RTU tonnage is the primary cost driver. Larger units require a larger crane, more crane time, and greater rigging complexity. A 3-5 ton standard commercial RTU replacement runs toward the lower end of the $20,000 to $150,000 CAD range; a 25-ton or larger unit with complex crane positioning runs toward the higher end.
Curb adaptor requirements add cost when a custom fabricated adaptor is needed. Road closure permit costs vary by street classification and permit duration. Gas supply upgrades, where an older pipe is undersized for the replacement unit’s higher gas input rating, add gas piping labour and material to the scope. Off-hours or weekend scheduling carries a labour premium that is disclosed in the written scope before any commitment is made.
All of these cost elements are itemised in the written project scope. There are no undisclosed additions after scope approval.
Serving property managers and commercial operators across Toronto and the GTA
Our team serves commercial properties across Toronto, North York, Etobicoke, Scarborough, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, and the Durham region, including Ajax, Pickering, and Whitby. Property managers handling multi-building portfolios receive a full documentation package after every replacement: written commissioning report, COI and WSIB certificates, equipment manufacturer’s warranty documentation, and a project summary for capital planning records.
For properties where the RTU replacement follows a diagnostic that identified the unit as beyond economical repair, see our commercial RTU repair service for the diagnostic process and repair pricing. For buildings with planned maintenance agreements that include regular RTU inspections and annual condition reporting, our commercial HVAC preventative maintenance contracts cover biannual servicing, documented readings, and priority scheduling when replacement becomes necessary. Any commercial gas compliance issues arising from the RTU inspection or during commissioning are handled in-house by our G1/G2 certified technicians on the same visit.
To scope a crane replacement or request a written estimate, call 647-254-4113 Monday through Saturday, 7:00 AM to 8:00 PM. Our commercial team responds to replacement enquiries within the same business day.
