Two tracks — one team
On contract, or on call.
Most facility directors run a mix: a planned maintenance program on the asset list, plus a dispatch number for the night a chiller drops.
Preventive maintenance contracts
In-depth inspections, regular adjustments, BMS / WebCTRL® monitoring, and reporting on each cycle. Each plan is tailored to your specific needs and your asset mix.
Service calls & repairs — 24/7
One dispatch number: 514-333-7333, option 1. A fleet of 25+ trucks covers heating, ventilation, air conditioning, piping, and controls — 24 hours a day, 7 days a week.
What's covered
Heating, ventilation, AC, piping, controls
Preventive scope spans every trade we install. Each visit includes in-depth inspections, regular adjustments, and continuous monitoring of equipment performance.
Heating
Scheduled inspections and regular adjustments on the heating plant, sequenced to anticipate failure before the cold season — extending equipment life and removing operational risk.
Ventilation
Filter and component replacement plus rigorous monitoring of performance — folded into the same scheduled cadence as the rest of the mechanical scope.
Air conditioning
In-depth inspections and regular adjustments on the cooling scope — sequenced to cut unplanned downtime, reduce operating costs, and extend equipment life.
Piping & hydronics
In-depth inspections and regular adjustments on the piping scope — keeping the distribution loops running at design conditions as part of the preventive maintenance cadence.
Controls & BMS monitoring
Real-time monitoring on Automated Logic / WebCTRL®. Continuous visibility lets technicians identify drift and act before a breakdown occurs.
Sector-specific scopes
Commercial, industrial, pharmaceutical, food processing, institutional, and data centers — preventive plans scoped to the equipment list and tolerances each environment demands.
Combustion analysis
Certified technicians evaluate and fine-tune the boiler's combustion process using diagnostic tools — maximizing efficiency, meeting safety compliance, and extending equipment life.
Built for multi-site portfolios
One agreement. Consolidated reporting.
Customized maintenance contracts that extend equipment life, lower energy use, and remove the surprise out of your operating budget — across Greater Montréal, the South and North Shores, and the GTA.
Tailored to your asset mix
Customized maintenance contracts that extend equipment life, lower energy use, and remove the surprise out of your operating budget — scoped to the equipment you actually operate.
Consolidated reporting across the portfolio
Coordinated coverage across multi-site portfolios — Greater Montréal, the South and North Shores, and the GTA — with consolidated reporting tailored to your asset mix.
ESG-ready dashboards
Energy-use reporting tied directly to your ESG dashboards and annual reporting cycles — built around BMS data flowing in continuously, not a once-a-year spreadsheet.
Contracted response on the dispatch line
When something breaks at 2am, the dispatcher already has your asset list, site contacts, and access rules on file — same dispatch number, same 25+ truck fleet.
How a contract gets built
From asset inventory to contracted response
Asset inventory
We walk your buildings and inventory the equipment that will fall under contract — across heating, ventilation, AC, piping, and controls.
Tailored contract scope
Visit cadence, scope of inspections, filter and component replacement, and reporting standard — all defined upfront against your asset mix.
Scheduled inspections + BMS monitoring
Site visits on cadence, regular adjustments, and continuous BMS / WebCTRL® monitoring of the installations between visits.
Reporting & contracted response
Inspection reporting each cycle, energy-use reporting tied to your ESG dashboards, and a contracted response tier when something fails between visits.
Preventive maintenance FAQ
What facility directors ask before they sign
How long is a typical maintenance contract, and how is the visit cadence determined?
Each plan is tailored to your specific needs — most clients run multi-year terms. Visit cadence is scoped against each site's equipment density and the tolerances your operation requires: lighter commercial loads absorb fewer visits per year, while office towers, multi-residential, and equipment-dense industrial or institutional sites carry more. The right cadence falls out of the asset inventory walkthrough.
What's included in the contract — and what's billed separately?
Included: in-depth inspections, regular adjustments, real-time monitoring on Automated Logic / WebCTRL® (where applicable), filter and component replacement, reporting each cycle, and energy-use reporting tied to your ESG dashboards. Billed separately: major equipment replacements, projects outside the inventoried scope, and any emergency call-out work that falls outside the contracted cadence.
Can you handle a multi-site portfolio across QC and the GTA?
Yes. We structure customized preventive-maintenance contracts that span multi-site portfolios across Greater Montréal, the South and North Shores, and the GTA — with consolidated reporting tailored to your asset mix. Our four offices (Laval HQ, Montréal, Toronto, Newmarket) support a diverse customer base across Canada with consistency and precision.
How fast do you respond on emergency calls for contract clients?
The same dispatch number — 514-333-7333, option 1 — is staffed 24 hours a day, 7 days a week. A truck from our fleet of 25+ vehicles is sent, covering heating, ventilation, air conditioning, piping, and controls. For contract clients, the dispatcher already has the asset list, site contacts, and access rules on file. Specific response targets are defined per contract based on building criticality and geography. See our 24/7 emergency HVAC repair page for the dispatch process in detail.
Can maintenance data tie into our ESG reporting?
Yes. The contract delivers energy-use reporting tied directly to your ESG dashboards and annual reporting cycles. We instrument the buildings on Automated Logic / WebCTRL® where applicable, and the data structure is built so your ESG team can fold it into annual disclosures and compliance audits without rework.
What does adding controls optimization layer on top of preventive maintenance?
Preventive maintenance keeps the equipment running; controls optimization continuously tunes how it runs. Our integrated control and optimization system gives complete visibility into equipment status, lets technicians identify drift and act before a breakdown occurs, and automatically tunes setpoints to reduce energy and operating cost. See our HVAC controls optimization service for the full scope.
