Climate Systems Built for Business.
H&C designs, installs, and services commercial HVAC systems for offices, retail spaces, restaurants, and industrial facilities across the Greater Toronto Area. Licensed, insured, and available 24/7.
Commercial HVAC Services Across the GTA
From rooftop unit installation to walk-in cooler repair, H&C delivers full-service commercial HVAC solutions with the responsiveness of a family-run business and the capacity to handle projects of any scale.
Rooftop Units (RTU)
Installation, replacement, and servicing of packaged rooftop units from 2 to 25+ tons. We handle Carrier, Lennox, Trane, and Daikin systems for flat-roof commercial buildings across the GTA.
VRF & Multi-Zone Systems
Variable refrigerant flow systems provide independent zone control for multi-story offices and mixed-use buildings. Ideal for retrofits where ductwork isn't practical — each zone gets its own thermostat.
Commercial AC & Heating
Split systems, packaged units, and make-up air units for commercial spaces. We size systems based on heat load calculations to match your building's actual requirements — not rules of thumb.
Preventive Maintenance Plans
Scheduled inspections, filter changes, coil cleaning, and refrigerant checks keep your systems running efficiently and extend equipment life. Quarterly, semi-annual, or annual plans available — tailored to your facility.
Commercial Refrigeration
Walk-in coolers, walk-in freezers, reach-in display cases, and prep tables. We service and install refrigeration systems for restaurants, grocery stores, convenience stores, and food processing facilities.
Commercial Water Heaters
High-capacity tank and tankless commercial water heaters for restaurants, hotels, laundromats, and multi-unit buildings. We install and service Bradford White, Rinnai, and Navien commercial units.
Ventilation & Air Quality
Kitchen exhaust, make-up air units, energy recovery ventilators (ERVs), and commercial air filtration. We design ventilation solutions that meet Ontario building code requirements and keep indoor air fresh.
24/7 Emergency Breakdown Service
A failed AC system in July or a dead heating unit in January can shut down your business. Our emergency response team is available around the clock — we prioritize commercial accounts and dispatch immediately.
Controls & Building Automation
Programmable thermostats, BAS integration, and smart scheduling for multi-zone commercial buildings. Reduce energy costs with automated setback schedules and remote monitoring capabilities.

Common Commercial HVAC Questions
What size commercial HVAC system does my building need?
System sizing depends on square footage, ceiling height, occupancy, window area, insulation, and heat-generating equipment. We perform a detailed Manual N or Manual J load calculation during our free site assessment to determine the right capacity — oversized systems waste energy and undersized ones can't keep up.
How often should commercial HVAC systems be serviced?
Most commercial systems should be inspected at least twice a year — once before cooling season and once before heating season. High-traffic facilities like restaurants and healthcare clinics benefit from quarterly service. Our maintenance plans include all scheduled visits, filter replacements, and priority emergency response.
Do you handle permits and inspections for commercial HVAC work?
Yes. All work that requires a permit under Ontario building code or TSSA regulations is fully permitted and inspected. We handle the entire process — application, scheduling, and final sign-off. You receive copies of all permits and inspection certificates for your records.
What is your emergency response time for commercial clients?
We dispatch immediately for commercial emergencies — 24 hours a day, 7 days a week, including holidays. Maintenance contract clients receive priority scheduling. For non-emergency service calls, we typically schedule within 24–48 hours.
Can you work on my building's existing rooftop units?
We service all major RTU brands including Carrier, Lennox, Trane, Daikin, York, and Rheem. Whether your unit needs a repair, a refrigerant recharge, or a full replacement, our commercial team has the experience and parts access to handle it efficiently.
Do you offer financing for commercial HVAC installations?
Yes. We offer flexible financing options for commercial HVAC projects, including equipment leasing and deferred payment plans. Contact us for details tailored to your project scope and timeline.
