COMMERCIAL · HVAC & MECHANICAL
Rooftop units that fail in the middle of a July heat wave. VRF and VAV systems serving office floors where one zone is freezing and the next is sweating. Makeup air and kitchen exhaust that has to be balanced exactly right or the fryers shut down and the dining room fills with smoke. Caspian runs a dedicated commercial team for RTUs, VRF/VAV, makeup air, and exhaust across Toronto and the GTA — with 24/7 priority response for restaurants and retail where downtime means closed business.
A focused commercial scope: the rooftop, refrigerant, and air-side equipment that keeps GTA office buildings, restaurants, retail spaces, and multi-unit common areas comfortable, code-compliant, and open for business.
Install, service, and full change-outs on packaged RTUs — Carrier, Trane, Lennox, AAON. Crane coordination, curb adapters, gas and electrical disconnects handled in-house. Weekend installs available for retail.
Daikin and Mitsubishi VRF/VRV — design support, install, commissioning, and ongoing service. Ideal for office floors, hotels, and mixed-use buildings where every zone needs independent control.
VAV box service, reheat coil work, and full-system balancing for Class B and C office buildings. We diagnose the "one floor is freezing, the next is sweating" problem and fix it properly.
Restaurant and food service makeup air units (MUA), Type I and Type II hood exhaust, and full kitchen ventilation balancing. Without the right MUA-to-exhaust ratio, the line shuts down — we get the numbers right.
We work cleanly with your existing BAS — Distech, Honeywell, Siemens, JCI Metasys. Sensor calibration, scheduling, alarm setup, and proper integration of new equipment into the building's control system.
Quarterly visits with a written checklist: belts, bearings, filters, coils, refrigerant charge, gas pressure, condensate, electrical. Documented service tickets, photos, and a year-end equipment report.
A retail RTU change-out and a restaurant hood exhaust balance are not the same job. We staff and schedule each one the way it should be done.
VAV balancing, RTU service, and after-hours scheduling so the tenants don't see a wrench. We integrate with the existing BMS (Distech, Metasys, Honeywell), document setpoint changes, and keep the property manager looped on every visit.
Type I and Type II hood exhaust, makeup air balancing, and kitchen mechanical load planning for new builds and renos. We know what the inspector is going to check, and we know what a kitchen actually needs to keep running through a Saturday night service.
RTU change-outs, refrigeration tie-in, and weekend installs to avoid retail disruption. One crew, one mobilisation, one shutdown — your store opens Monday morning with full cooling.
Corridor makeup air, parking garage exhaust, and hydronic and boiler service for older Toronto stock — including the cast-iron radiator buildings where the original mechanical drawings are long gone.
We've spent enough years on commercial portfolios to know the things that actually matter — and the things vendors say matter but never deliver.
01 / CONTRACTS
Belts, filters, coils, refrigerant charge, electrical checks — caught and fixed before a tenant ever picks up the phone. Most calls we get from contract clients are scheduled, not emergencies.
02 / DOCUMENTATION
Every visit gets a written ticket filed within 48 hours — photos, readings, parts replaced, recommendations. Audit-ready, exportable, and on file when you need it for board reporting or insurance.
03 / CONTACT
You get a dedicated commercial project manager — not a dispatcher and a new tech every time. They know your building, your equipment, and your tenants by the second visit.
04 / RESPONSE
Contract clients jump the queue. No waiting behind residential calls, no after-hours surcharge, and a guaranteed response window for true emergencies — heat down in February, no cooling in July.
