Toronto Commercial HVAC services commercial chillers for office towers, hospitals, universities, long-term care and industrial plants across Toronto and the GTA. We repair, rebuild and replace air-cooled, water-cooled and centrifugal chillers from 20 to 500 tons, and we maintain 85+ chiller plants on PM. Brands include Trane Series R and CenTraVac, Carrier 30XA and 19XRV, York YLAA and YK, and Daikin WMC and WME.
Chillers rarely fail without warning. Approach temperatures creep up as tubes foul. Purge units run more often as air leaks in. Bearing vibration rises months before a compressor fails. Oil analysis shows wear metals. Chilled water delta-T shrinks and the plant runs more machines than it needs. Plants that are measured get fixed on schedule. Plants that are not get fixed in an emergency in July.
Plant assessments start at about $4,500. Compressor rebuilds run $18,000 to $65,000 per machine, and replacements run $85,000 to $450,000. Every rebuild and replacement is planned around keeping the building cool.
What Does Commercial Chiller Service Include?
Assessment and testing
Vibration analysis, oil analysis, refrigerant analysis, eddy current tube testing and a review of BAS trends. The result is a written condition report per machine.
Repair
Starters and VFDs, controls and sensors, purge units, oil pumps, valves, refrigerant leaks and pumps. Emergencies get a 2-4 hour response.
Rebuild
Compressor and motor rebuilds with new bearings, seals and gaskets, tube plugging or retubing, and full start-up testing.
Replacement
Rigging plan, demolition, new chiller set, piping and electrical, controls and commissioning to ASHRAE 90.1.
Chiller Types We Service

|---|---|---|
| Scroll (air-cooled) | 20-150 tons | Low-rise offices, schools, retail |
| Screw (air or water-cooled) | 70-500 tons | Hospitals, industrial, mid-rise |
| Centrifugal (water-cooled) | 200-500+ tons | Downtown towers, campuses |
| Magnetic bearing centrifugal | 60-500 tons | Retrofits seeking efficiency |
Signs Your Chiller Needs Service
- Approach temperatures rising above design.
- Purge unit running more often than normal.
- Higher bearing vibration or new noise.
- Chilled water supply temperature drifting.
- More chillers running than the load requires.
- Upper floors getting comfort complaints first.
Rebuild vs Replace
We put rebuild cost, replacement cost, remaining life and annual energy cost side by side for every machine. A machine with good tubes and a serviceable refrigerant usually rebuilds well, as the Bay Street tower rebuild showed with an 18% plant energy reduction. A machine past 25-30 years on an obsolete refrigerant usually points to replacement. Replacement programs can also be planned through commercial HVAC replacement.
Chiller Plants and the Rest of the System
Water-cooled chillers depend on the cooling tower, and every plant depends on controls. We bundle cooling tower service and BMS and HVAC controls into plant programs so one team owns the whole loop. Office towers can see our commercial HVAC for offices page for tenant-side programs.
Chiller Service Across Toronto and the GTA
We service plants in Bay Street and King West towers, Yonge-Sheppard and NYCC offices, downtown hospitals and universities, Airport Corporate Centre offices in Etobicoke and Hwy 410 industrial plants in Brampton.
