What it costs
Montreal & West Island, 2026After diagnosis, we explain the recommended repairs and provide pricing for your approval. Maintenance and replacement quotes depend on your equipment, site access and the work required.
Questions buyers ask
Almost always zoning and solar gain rather than capacity. We measure before balancing, and we tell you if the equipment cannot deliver what the floor plan asks of it.
Yes. We can arrange work outside business hours when preferred, and many service visits can also be completed during regular hours. Tenant-facing work is scheduled with your property team.
A yearly condition report with remaining life per unit, so a rooftop replacement lands in a budget year rather than in an emergency.
Regularly. Duct and diffuser changes follow the new floor plan, coordinated with the general contractor.
It depends on the terms between landlord and tenant. We work for whoever holds the contract and copy the other party on the report if you ask us to.
Often, yes. Most complaints trace to dampers, diffuser throw and a thermostat in the wrong place, not to undersized equipment.
We set the schedules and the override so tenants can call for extra hours, and the runtime is logged for rebilling.
Yes. CO₂, temperature and humidity readings at the desk that complained, with the readings written down rather than described.
