What's in a preventive contract

Built around your asset list, not a generic checklist

Every contract is scoped to the equipment you actually operate. The line items below are the spine — tailored cadence, cycle reporting, and ESG-ready data on top.

  1. Scheduled inspections tailored to your asset list

    A plan tailored to the equipment you actually operate, not a generic checklist.

  2. BMS / WebCTRL® monitoring (where applicable)

    Real-time performance monitoring across your installations.

  3. In-depth inspections and regular adjustments

    Rigorous monitoring of equipment performance, with adjustments on each visit.

  4. Real-time performance monitoring

    Complete visibility into equipment status across the contract year.

  5. Cycle reporting

    A record of what was checked, what was adjusted, and what to plan for next.

  6. Energy-use reporting

    Consumption data tied to your ESG dashboards and reporting cycles.

  7. Drift identification and early intervention

    Continuous monitoring lets technicians act before a breakdown occurs.

  8. Equipment-life optimization

    A proactive program designed to extend equipment life cycles and reduce operating costs.

  9. Contracted response tier

    When something does break, the dispatch line already has your asset list, contacts, and access rules on file.

HVAC capabilities

What's under the contract

Service coverage spans the full HVAC stack — preventive maintenance and 24/7 emergency repair backed by the trades that built the plant in the first place.

Scheduled inspections, filter changes, and equipment health checks on a contract — the work that keeps small problems from becoming after-hours calls.

Preventive maintenance

Service calls and repairs across heating, ventilation, AC, piping, and controls — for commercial portfolios in Quebec and Ontario.

Commercial HVAC repair

25+ service trucks across Quebec and the GTA, 24/7 dispatch when a chiller, boiler, or rooftop unit fails outside business hours.

Emergency HVAC repair

Trend reviews, sequence tune-ups, and BAS upkeep that keep the building running the way it was designed instead of slowly drifting.

HVAC controls

Boiler service, burner tuning, and combustion testing before and through every heating season.

Commercial heating

Chiller maintenance, refrigerant management, and pre-season startup so the cooling plant is ready before the first heat wave.

Commercial AC
