The Toronto rooftop market

## Why Rooftop Units in Toronto Need a Commercial Specialist

Most commercial buildings across Toronto and the GTA are heated and cooled by a **packaged rooftop unit**: compressor, coils, fans and a gas heat section in one cabinet on one curb. Large office towers add a **commercial chiller** and **cooling tower** plant, and every restaurant kitchen leans on a **make-up air unit**. A typical Toronto roof sees humid 32C afternoons, minus 20C mornings, freeze-thaw cycles and road dust, and the equipment wears accordingly.

Many units in GTA plazas and parks went in during the 1990s and 2000s and are now at or past their 15-20 year life. That is why **GTA property managers** are facing replacement decisions across whole portfolios at once, often while juggling several contractors, COI requests and tenants who cannot lose cooling for a day.

We built the company around that reality: **Red Seal HVAC-R** leads, **TSSA G1 + G2** gas techs, ESA electrical and **CRE-ticketed chiller techs** on one crew, published pricing, and the **Save on Energy Retrofit Program** paperwork filed before the crane is booked. We are an authorized **Lennox, Carrier, York, Trane, Daikin** dealer, so OEM parts are on the van.

Risk Disclosure

## Why Toronto Commercial Rooftop Jobs Go Sideways

Three failures cause 80% of the complaints property managers bring us.

01

### Wrong diagnosis

A residential tech misreads a commercial economizer and replaces parts that did not need it. We megger windings and test controls before anyone quotes a compressor.

02

### Wrong equipment match

A contractor quotes a 5-ton split when the roof needs a 10-ton packaged unit. Manual J/S sizing and a curb check come before the quote, not after the crane.

03

### Wrong rebate math

Nobody files Save on Energy and the PM leaves $8K-$30K on the table. We lock the pre-approval before equipment is ordered and net it on the invoice.

Fix it upstream: Red Seal HVAC-R diagnostics + Manual J/S sizing + rebate paperwork before the quote. 1,800+ GTA installs, 97% uptime.

## Good Fit / Not Our Focus

We stay on commercial roofs so the crew stays sharp on commercial equipment. If your job is on the right-hand list, we will tell you on the first call.

### Good fit

-   Rooftop units (RTUs)
-   Chillers
-   Cooling towers
-   Mechanical rooms
-   Portfolio contracts

Commercial, retail, office, mixed-use, condo tower, restaurant, clinic, school and industrial buildings across Toronto and the GTA.

### Not our focus

-   Residential
-   DIY
-   Parts-only
-   New construction design

No houses, cottages or furnace swaps. No parts sold over the counter. No design-build engineering for new construction.

Zero ambiguity

## Why GTA Property Teams Choose Rooftop Units Toronto Pros

Six things you can hold us to, every one of them backed by a number, a ticket or a named project.

### 24-Hour Written Quote

Repair, replacement or maintenance plan on paper within 24 hours of the site assessment. Parts, labour, crane, permit and HST on one line. No vague HVAC package.

### Published Per-Ton Pricing

### Full-Stack Commercial

RTUs, chillers, cooling towers, MUA, DOAS, VFDs and mechanical rooms: the jobs single-truck shops turn away. One contractor for the whole roof and the plant below it.

### Authorized Brand Dealer

Lennox, Carrier, York, Trane, Daikin, Rheem and American Standard with OEM parts stocked, so most repairs finish on the first visit.

### 24/7 Emergency RTU Response

How we are different

### A Commercial Shop, Not a Residential Company With a Lift

Rooftop Units Toronto Pros was founded in 2008 to do one thing: keep commercial equipment running on GTA roofs and in GTA plant rooms. We do not sell furnaces to homeowners in the off-season, and we do not send a residential tech up a ladder to guess at a 10-ton economizer.

That focus shows up in the paperwork. Every repair starts with a written tally. Every install starts with Manual J/S sizing and a curb check. Every qualifying retrofit starts with a Save on Energy pre-approval, which is how our Airport Rd client captured $87K that three other bidders never filed for.

It also shows up in the crew. Red Seal HVAC-R leads handle refrigeration, TSSA G1 and G2 techs handle gas, ESA handles electrical, and CRE-ticketed techs handle chillers and cooling towers from 100 to 2,000 tons. Sheet-metal fabricators build curb adapters in our shop, and controls specialists tie units into Honeywell, Johnson Controls Metasys, Siemens Desigo and Delta systems.

For property managers, it shows up as one point of contact, locked per-site pricing, COI in 24 hours on every request and Net-30 terms. 48 GTA sites are under active maintenance with us today.

How it works

## From Site Assessment to Commissioning Sign-Off

Five steps, the same on every job, from a single compressor to a 14-unit program.

1.  01
    
    ### Site assessment
    
    A Red Seal lead walks the roof, reads nameplates, checks curbs, access and electrical, and logs every symptom.
    
2.  02
    
    ### 24-hr written quote
    
    Parts, labour, crane, permit and HST on one line, plus the repair-vs-replace math when the unit is old.
    
3.  03
    
    ### Rebate pre-approval
    
    We file Save on Energy or Enbridge paperwork before equipment is ordered, so the rebate is locked in.
    
4.  04
    
    ### Install / repair
    
    WSIB crews, crane day and street-occupancy permits handled. Tenants get a schedule, not a surprise.
    
5.  05
    
    ### Commissioning sign-off
    
    Startup readings, controls check and a commissioning report you can file. Final 25% only after sign-off.
    

Standard 5-10 ton RTU: 3-5 business days from quote to startup.

### How long does a commercial rooftop unit install take in Toronto?

Standard 5-10 ton RTU: 3-5 business days from quote to startup. Crane coordination + roof reinforcement adds 2-3 days. Larger 15-25 ton packaged units: 5-10 business days. The clock starts once the written quote is signed and equipment is confirmed in stock. Lennox, Carrier and York 3-10 ton units are usually on a GTA distributor shelf, while 20-25 ton and heat pump RTUs can need a factory order. We book the crane and the City of Toronto street-occupancy permit while the unit ships, so the lift day is set before the equipment lands. Startup includes a commissioning sheet you can file with your capex records.

### Do you handle condo board Status Certificate submissions for rooftop work?

Yes. Status Certificate review + strata-approved equipment specs are included on every condo tower project in Yorkville, Harbourfront, Liberty Village, King West and surrounding downtown towers. Submission turnaround is 7 business days. We prepare the equipment cut sheets, sound data, structural notes and a work schedule the board can read in one sitting, and we answer questions at the board meeting if you want us there. Tenant and owner notices are drafted for the manager to send.

### What's included in your 24/7 emergency rooftop unit response?

A dispatched tech on-roof within 2-4 hours in the GTA core. Diagnostic, parts check, and temp-cooling or temp-heating setup if the unit cannot be restored same-day. After-hours rate $280-$425/hr. Restaurant, retail, dental and medical sites get a priority queue. The call is answered by dispatch and routed to a Red Seal tech, not logged as a call-centre ticket. Our vans carry the contactors, capacitors, igniters, flame sensors and fan motors that cause most no-cool and no-heat calls, so many units run again on the first visit.

### How does the Save on Energy Retrofit Program rebate work?

$200-$1,500 per ton on qualifying high-efficiency retrofits. We complete the pre-audit, submit the application, and net the rebate against your final invoice. A typical office + retail retrofit captures $8,000-$30,000 in rebates. The key is timing: pre-approval has to land before equipment is ordered, and approval takes 4-8 weeks. That is why our quotes show the rebate-net number on the same page as the install price. On the Mississauga Airport Rd 14-RTU program the filing captured $87K that the other bidders never applied for.

### Do you service chillers and cooling towers, or only rooftop units?

Yes to all three. CRE-ticketed chiller techs handle centrifugal, screw and absorption chillers from 100-2,000 ton. Cooling tower work includes fill replacement, basin cleaning and water treatment. Chiller retrofits range $50K-$500K. That covers Trane CenTraVac, Carrier AquaForce, York YK and Daikin WMC machines plus BAC, Marley and Evapco towers. Our Bay Street 42-storey retube ran $148K over a 9-day window with crane permits and condo board communication handled by our team.

### What rooftop unit brands do you install and repair?

We are an authorized Lennox, Carrier, York, Trane, Daikin, Rheem and American Standard dealer for RTUs and packaged chillers, with OEM parts stocked. We also service Trane CenTraVac, Carrier AquaForce, York YK and Daikin WMC chillers and BAC, Marley and Evapco towers. Controls work covers Honeywell, Johnson Controls Metasys, Siemens Desigo and Delta.

### Can you handle multi-site property manager portfolios?

Yes. 48 GTA sites are under active maintenance today on portfolio contracts from $35K-$180K per year, with locked per-site pricing from $295/unit/yr, one point of contact, quarterly inspections, Net-30 terms and COI in 24 hours. Every visit produces a written report per unit, and the portfolio summary shows which units are trending toward replacement so you can plan capex instead of reacting to it.

### What's the difference between a packaged RTU and a split system?

A packaged RTU holds the compressor, coils, fans and heat section in one rooftop cabinet on one curb; a split system separates an outdoor condenser from an indoor air handler. Packaged units save interior space and simplify service on flat commercial roofs. The most common mismatch we fix is a 5-ton split quoted where the roof and the load call for a 10-ton packaged unit.

### Do you offer annual preventive maintenance contracts?

Yes. Annual RTU maintenance runs $295-$450 per unit per year with quarterly inspections, or $240-$340 per unit for 12+ units on one site. Every visit ends with a written report covering electrical, refrigerant, coils, belts, economizer and controls. Contract sites get priority dispatch and locked labour rates.

### What building types do you service and which do you skip?

We service commercial, retail, office, mixed-use, condo tower, restaurant, clinic, school and industrial buildings across Toronto and the GTA. We skip residential, DIY and parts-only requests, new-construction design and cottage country so the crew stays focused on commercial equipment.
