Commercial HVAC Service
Light commercial HVAC — small offices, retail spaces, restaurants, dental and medical practices, and similar small-business properties — has different requirements than residential work. Equipment is typically rooftop units (RTUs) rather than residential split systems, capacity sizing is more demanding (full occupancy creates higher loads), uptime matters (a closed business loses revenue) and after-hours service is essential.
We handle light commercial work across Halton Hills — service, repair, and replacement of rooftop units up to about 25 tons of capacity. We focus on the mechanical work; for larger commercial projects (large multi-tenant buildings, manufacturing facilities), we'll be honest about whether we're the right fit.
Commercial HVAC scenarios we handle
Typical commercial work in Halton Hills:
- Rooftop unit (RTU) repair and replacement — most small commercial buildings use packaged rooftop units. Standard service.
- Restaurant kitchen exhaust and makeup air — specific code requirements (TSSA and Halton Region for ventilation). We coordinate with kitchen exhaust specialists when needed.
- Office building heating and cooling — typical commercial office spaces under 25,000 sqft.
- Retail and small commercial properties — strip mall units, standalone commercial buildings, light industrial.
- Dental, medical, and veterinary practices — specific air quality and ventilation requirements that we handle.
- Multi-tenant building common areas — heating and cooling for shared spaces, not individual unit work.
- Emergency commercial service — businesses can't operate without HVAC; we prioritize commercial emergency dispatch.
How commercial HVAC engagements work
- 01
Site assessment
We evaluate the existing system, building load requirements (often higher than the original install was sized for if the space has been reconfigured or occupancy has changed), and operational priorities (uptime, energy cost, comfort).
- 02
Service or replacement plan
For service work, we identify the specific issues and provide options. For replacement, we provide multiple equipment options at different efficiency tiers, with operating cost projections and any commercial energy rebates that apply.
- 03
Installation timing
We coordinate timing to minimize business disruption — after-hours installs, weekend work, or temporary cooling/heating equipment during installations as appropriate.
- 04
Maintenance contracts
Most commercial customers benefit from quarterly or bi-annual maintenance contracts rather than ad-hoc service. Predictable cost, scheduled work that minimizes business disruption, and priority emergency response when issues do arise.

What commercial HVAC costs in Halton Hills
Commercial pricing varies more than residential because of the wider range of equipment sizes and project complexity. Rough ranges:
- Commercial diagnostic service call: $220–$320 (more complex than residential, typically takes longer)
- Standard RTU repair: $400–$1,800 depending on component
- 3-ton commercial RTU replacement: $8,500–$13,000 installed
- 5-ton commercial RTU replacement: $11,000–$17,500 installed
- 10-ton commercial RTU replacement: $18,000–$28,000 installed
- Quarterly maintenance contract: $200–$600/visit depending on system size and scope
Commercial equipment qualifies for different rebate programs than residential — we navigate the commercial energy rebate landscape (Save on Energy commercial programs, Enbridge commercial rebates, etc.) for qualifying installations.
Commercial work also typically requires liability insurance documentation, WSIB clearance certificates, and sometimes specific contractor pre-qualification — we provide all standard documentation.
Commercial HVAC questions
Do you handle large commercial buildings?
We handle light commercial work — small offices, retail, restaurants, small medical practices — typically up to about 25 tons of total cooling capacity. For larger commercial projects (large multi-tenant office buildings, manufacturing facilities, schools, hospitals), we'll be honest about whether we're the right fit. Sometimes we are; sometimes a larger commercial-focused HVAC firm is a better match.
Can you do after-hours commercial service?
Yes — and we recommend it for most commercial work. Installing or servicing rooftop units during business hours typically disrupts operations. After-hours and weekend service costs more but minimizes business impact. For genuine emergency commercial service (failed HVAC during business hours), we have 24/7 dispatch.
What about commercial maintenance contracts?
Most commercial customers benefit from quarterly or bi-annual maintenance contracts. Costs typically run $200–$600 per visit depending on system size. Maintenance contracts include scheduled visits, priority emergency response, and parts/labour discounts on any repairs needed. The cost is more predictable than ad-hoc service and the equipment lifespan is meaningfully extended.
Do you handle restaurant kitchen ventilation?
Partially. We handle the conditioning side (heating, cooling, makeup air integration with HVAC). For the kitchen exhaust specifically — hood cleaning, fire suppression, grease management — we partner with kitchen exhaust specialists. The two systems need to work together; we coordinate.
Are commercial energy rebates available?
Yes, and they're often substantial. Save on Energy runs commercial efficiency programs (Retrofit Program, Small Business Lighting). Enbridge runs commercial gas-saving incentives. Both can stack on commercial HVAC retrofits. We navigate the rebate landscape for qualifying installations — eligibility differs from residential programs.
How quickly can you respond to a commercial emergency?
During business hours, within 2–4 hours for genuine emergencies. After-hours commercial dispatch typically responds within 4–6 hours. For commercial customers on maintenance contracts, response times are faster (priority dispatch). For a closed business losing revenue, the faster response time alone often justifies the contract.
