We replace rooftop units, split systems, furnace sections, unit heaters, boilers, make-up air units and chillers, either one unit at a time or as phased building-wide programs. Replacement decisions usually get forced by a failure. A 21-year-old rooftop unit loses its compressor in July. A boiler heat exchanger cracks in January. An R-22 chiller develops a leak nobody can afford to recharge. When that happens, the replacement gets ordered in a rush, often copying the old nameplate size, and the rest of the ageing equipment keeps waiting for its turn to fail. A planned program avoids all of that. Single-unit replacements typically cost $12,000 to $45,000. Building-wide programs run $85,000 to $680,000. Every unit we audit or replace gets reserve-fund ready documentation, and all replacement work carries a 2-year labour warranty. ## What Does a Commercial HVAC Replacement Program Include? ### Per-unit condition audit We record nameplate data, refrigerant type, age, heat exchanger and coil condition, repair history and current performance for every unit. Photos and a condition score go into a single spreadsheet. ### Ranking and budgeting Units are ranked by failure risk and repair-cost ratio. You get replacement costs per unit, grouped into phases that fit your capital plan. ### Right-sizing Each space gets a load calculation before ordering. Buildings that changed use or were oversized from day one often drop tonnage, which lowers both the capital and operating cost. ### Phased execution Crane days, road permits and swaps are scheduled around tenants. For rooftop unit installation [/rooftop-unit-installation/ →](/rooftop-unit-installation/) , we fabricate roof adapters so new units drop onto existing openings without roof rework. ## Types of Commercial HVAC Replacement | Equipment | Typical replacement trigger | Typical range | | --- | --- | --- | | Packaged rooftop unit | Year 18-22, compressor or heat exchanger failure | $12K-$45K per unit (larger units to $95K) | | Boiler plant | Year 25-35, cracked sections or heat exchanger | $60K-$280K | | Chiller | Year 25-30, R-22 or major compressor failure | $85K-$450K | | Make-up air unit | Burner section or casing failure | $14K-$45K | | Unit heaters | Heat exchanger failure, Red Tag | $3K-$9K each | ## When Is It Time to Replace? - **Age.** RTUs past 18-22 years and chillers past 25-30 years are on borrowed time. - **Repair-cost ratio.** One repair costs more than half of a new unit. - **Refrigerant.** R-22 systems with leaks are costly to keep alive. - **Safety.** Cracked heat exchangers and failed venting on gas equipment. - **Comfort and energy.** Units that cannot hold setpoint, or energy use climbing year over year. ## Repair vs Replace: A Worked Example A 22-year-old 15-ton RTU needs a $5,200 compressor. A new right-sized 12.5-ton unit installed costs about $38,000. The repair buys maybe two to four more years on a unit with an ageing heat exchanger and R-22 refrigerant. The replacement comes with a 2-year labour warranty, current refrigerant, better efficiency and 15 to 20 years of life. In most cases the replacement wins, but the numbers are in writing so you can decide. If you just need the immediate fault fixed, our commercial HVAC repair [/commercial-hvac-repair/ →](/commercial-hvac-repair/) team can quote both. ## Replacement Across Toronto and the GTA We have run phased RTU programs in Mississauga industrial parks, Etobicoke QSR portfolios and Vaughan retail, and boiler and chiller replacements in downtown and North York towers. The Etobicoke QSR program started with a 32-store age audit and a $385,000 phase 1.

Why Us ## Why Choose Toronto Commercial HVAC for HVAC Replacement? ### Data Before Decisions Every program starts with a written per-unit audit, so you replace the right units first. ### Right-Sized, Not Copied New units are sized from a load calculation, not the old nameplate. Many buildings drop tonnage on replacement. ### Phasing Around Tenants Weekend crane days and overnight swaps keep tenants operating. The Mississauga 14-RTU program had zero tenant downtime. ### Reserve Fund Ready Age, condition, replacement cost and expected life per unit, in a format your reserve fund consultant can use. ### Incentive Paperwork Handled Enbridge and IESO pre-approval steps are built into the schedule so you do not lose funding on a technicality. ### 2-Year Labour Warranty All replacements carry a 2-year labour warranty, with manufacturer parts coverage registered at start-up. ## Repair or replace?

Phased programs covering several units usually run $85,000 to $250,000, and full-building programs with boiler or chiller plants run up to about $680,000. Costs rise with larger tonnage, downtown crane logistics, structural changes, electrical service upgrades and after-hours phasing. We start with a per-unit audit so the budget is built on real condition data, and we look for Enbridge or IESO incentives before anything is ordered. ### When should we replace instead of repair? + For most buildings, reactive repair stops paying around year 18-22 for rooftop units and year 25-30 for chillers. Other triggers include a single repair costing more than half of a replacement, R-22 systems with major refrigerant leaks, cracked heat exchangers on older units, and repeated failures of the same component. Our audits put the repair cost, remaining life and replacement cost side by side so the call is easy to defend to a board or owner. ### Can you replace equipment without shutting down our tenants? + Yes. Most replacements happen on weekend crane days or overnight. For boilers and chillers we stage temporary heat or cooling when needed. Our Mississauga industrial park program replaced 14 RTUs in six weeks with zero tenant downtime. ### What happens to R-22 equipment? + R-22 is no longer produced, so repair refrigerant is scarce and expensive. We recover the refrigerant under federal and provincial rules and replace the system with current refrigerants such as R-410A or R-454B. ### Do you provide documentation for reserve fund studies? + Yes. Every audit and replacement includes age, condition, cost and expected remaining life per unit, which reserve fund consultants and asset managers use directly. ### Will new equipment be the same size as the old? + Not always. Many older buildings were oversized or have changed use. We run a load calculation for each space and size the new unit to the actual load. ### Are there rebates for replacing old equipment? + Often. Enbridge and IESO programs support high-efficiency heating, heat pumps and controls. Some programs require pre-approval before equipment is ordered, so we check eligibility at the audit stage. ### How long does a replacement take? + A single RTU swap is usually one day on site. Equipment lead times add four to twelve weeks. Boiler and chiller plants take one to six weeks on site depending on size. ### What warranty comes with replacement work? + A 2-year labour warranty on all replacements, plus manufacturer parts warranties registered at start-up. ### Can you replace a whole portfolio over several years? + Yes. We build multi-year phased plans ranked by risk, so capital spend is spread evenly and the worst units go first.
