Every RFP season we sit across the table from property managers holding three quotes with a $30,000 spread between them. This is the guide I wish every PM had before that meeting — realistic 2026 pricing across every major line item, calibrated to actual GTA high-rise buildings we service today.
The number your board actually cares about: per-unit monthly maintenance
For any commercial HVAC contract discussion at a condo AGM, the single number that matters is dollars per unit per month, all-inclusive. Everything else — annual totals, hourly rates, contract terms — flows from there. Here are the 2026 GTA ranges, calibrated across 240 buildings we service or bid on annually:
| Building Profile | Realistic 2026 Range |
|---|---|
| 50–99 unit low-rise, simple hydronic | $22 – $34 / unit / mo |
| 100–200 unit mid-rise, centralized plant | $18 – $28 / unit / mo |
| 200–500 unit high-rise, chillers + boilers + BAS | $18 – $32 / unit / mo |
| 500–1,000 unit tower, district energy interface | $14 – $24 / unit / mo |
| 1,000+ unit master-planned complex | $12 – $20 / unit / mo |
These ranges assume all-inclusive flat-rate contracts — meaning 24/7 emergency dispatch, water treatment, controls calibration, TSSA inspection coordination, and filter media are included. If you're seeing quotes below the low end of these ranges, verify what's excluded. It's almost always the emergency response, which is where the real cost lives.
Quick calibration test: a 240-unit high-rise should spend $52,000–$92,000 per year on all-inclusive HVAC maintenance in 2026. If you're spending less, you're probably paying the difference in emergency callouts. If you're spending more, you have padding or one-off complexity.
Boiler replacement costs in Toronto: what to actually budget
Boiler replacement is the single largest HVAC capital item most GTA high-rise boards will face during their tenure. Costs vary dramatically based on boiler type, capacity, and access to the mechanical room.
| Boiler Category (per unit) | 2026 Installed Cost |
|---|---|
| Cast-iron sectional, 500K–1M BTU | $28,000 – $48,000 |
| Condensing gas, 500K–1M BTU | $38,000 – $62,000 |
| Cast-iron sectional, 2 MMBTU | $42,000 – $65,000 |
| Condensing gas, 2 MMBTU | $52,000 – $85,000 |
| Modular condensing bank (4 x 500K) | $95,000 – $145,000 |
Add 15–30% if the boiler must be brought through elevators or a limited-access mechanical penthouse — the rigging and staging can rival the equipment cost in tight buildings. Condensing boilers cost 30–45% more upfront but deliver 15–25% fuel savings over their 15–20 year service life. In a building spending $180k/year on gas, that's $30k–$40k of annual savings — pays back the premium in 4–6 years.
Common mistake we see: buildings replacing a failing boiler with the same type. If your cast-iron sectional from 2003 has died, replacing with a modern condensing unit is almost always the right economic choice, even at the higher capital cost. The exception: buildings where the chimney/venting infrastructure prohibits condensing (which needs Category IV stainless steel, not the terracotta liner in older buildings).
Chiller replacement: the big-ticket capital decision
Chiller replacement is the biggest single capital number most PMs will ever handle. The range in 2026 GTA:
| Chiller Type & Capacity | 2026 Installed Cost |
|---|---|
| Air-cooled screw, 100 tons | $110,000 – $170,000 |
| Air-cooled screw, 200 tons | $180,000 – $260,000 |
| Water-cooled centrifugal, 250 tons | $220,000 – $320,000 |
| Water-cooled centrifugal, 400 tons | $310,000 – $480,000 |
| Cooling tower replacement (250 tons) | $85,000 – $145,000 |
These are installed prices including basic controls integration, standard refrigerant charge, disposal of old equipment, and pipe modifications up to 3 metres. They exclude:
- Rooftop crane lifts (add $8,000–$25,000 depending on street closure requirements)
- New concrete housekeeping pads if the old footprint doesn't match
- BAS integration if your existing controls are pre-2010
- Refrigerant conversion if the old chiller ran R-22 or R-11 (nearly all pre-2015 chillers)
The "conversion" line item is the sneaky one. Every quote should specify which refrigerant the new unit uses (R-134a or R-1234ze are current standards) and whether piping/cleaning is included when transitioning from older refrigerants.

Rooftop Make-Up Air Units (MAUs) and floor-mounted Air Handling Units (AHUs) are the third major capital item. For a typical GTA high-rise:
| Air Handler Type | 2026 Installed Cost |
|---|---|
| Corridor MAU, 5,000 CFM | $42,000 – $68,000 |
| Corridor MAU, 10,000 CFM (typical hi-rise) | $62,000 – $95,000 |
| Rooftop AHU, 8,000 CFM (commercial floor) | $55,000 – $88,000 |
| In-suite fan coil replacement (per unit) | $1,200 – $2,400 |
| Cooling tower media replacement | $12,000 – $22,000 |
The hidden costs most quotes exclude (and how to force them onto the sheet)
Any HVAC RFP should force each bidder to disclose these five items explicitly:
1. After-hours emergency response rate
Ask each contractor: "Under this contract, what is the hourly rate for emergency dispatch between 6 PM and 8 AM, weekends, and statutory holidays?" A contract with a flat rate that includes emergency dispatch is fundamentally different from one that charges $385/hour after 6 PM. In a normal GTA high-rise year, expect 8–14 emergency callouts — the delta is $6,000–$18,000 annually.
2. Water treatment chemicals
Boiler and chiller water treatment costs $1,200–$3,600 per year in chemicals. Every contract we see split into "labour" and "chemicals" charges chemicals as a change order. Force it into the flat rate.
3. Refrigerant top-ups
Any chiller loses refrigerant slowly. A 10-lb top-up of R-134a is currently $850–$1,400. Some contractors quote a low base rate then charge every top-up as a separate service. Language to include in the RFP: "Contract shall include up to 30 lbs/year of refrigerant top-up across all refrigeration equipment at no additional cost."
4. Controls calibration
Building Automation Systems drift. Sensor calibration, actuator adjustment, and schedule optimization is a 2-day annual job worth $1,800–$3,200. If it's not in the flat rate, you're paying for it later as "additional services."
5. TSSA inspection coordination
The Ontario TSSA inspection is annual and mandatory. Most contractors charge $450–$850 per inspection just to attend and provide documentation. Force it into the flat rate.
What a real 240-unit high-rise spends in 2026
Rather than abstract ranges, here's a realistic annual spend for a specific case: 240-unit condo, built 2008, two 2 MMBTU condensing boilers, one 200-ton air-cooled chiller, one 10,000 CFM corridor MAU, standard hydronic distribution, Honeywell BAS from 2015.
| Line Item | 2026 Annual Cost |
|---|---|
| All-inclusive flat-rate maintenance | $62,400 |
| Water treatment (in flat rate) | Included |
| Emergency dispatch (in flat rate) | Included |
| TSSA inspection (in flat rate) | Included |
| Filter media (in flat rate) | Included |
| Reserve fund contribution (HVAC portion) | $24,000 |
| Utility gas (heating season) | $142,000 |
| Utility electricity (cooling season) | $78,000 |
| Total annual HVAC operating cost | $306,400 |
That's $1,277 per unit per year — a useful benchmark to hold your board budget against. If your total HVAC operating cost per unit is significantly higher than this, you have room to optimize. Significantly lower usually means deferred maintenance that will surface as capital cost within 3–5 years.
How to use these numbers at your next AGM
- Calibrate your current spend. Divide your total 2025 HVAC operating spend by unit count. Compare to the benchmarks above.
- Isolate the maintenance line. The flat-rate contract number is the one most directly controllable. Aim for the middle of the range for your building profile.
- Isolate the capital reserve. The reserve fund contribution for HVAC should be roughly 8–12% of the total HVAC line — sized to fund equipment replacement on 15–20 year cycles.
- Force explicit hidden-cost disclosure in the next RFP. The five items above should be flat-rate inclusions, not exclusions.
