Question 1

What should a commercial HVAC maintenance contract include in Toronto?

Accepted Answer

A properly structured commercial HVAC maintenance contract in Toronto should include spring and fall seasonal visits per unit, filter replacement on a documented schedule, evaporator and condenser coil cleaning annually, refrigerant pressure verification at every visit, electrical component inspection, written reports with photos within 24 hours, and priority emergency response. Any contract missing these elements has meaningful gaps.

Question 2

How much does a commercial HVAC maintenance contract cost in Toronto?

Accepted Answer

Commercial HVAC maintenance contracts in Toronto typically cost $2,400-$6,000 per year for small buildings with 1-3 rooftop units, $6,000-$18,000 per year for mid-size buildings, and $18,000-$60,000+ per year for large buildings with BAS integration. Always verify whether truck charges and fuel surcharges are included in the stated price.

Question 3

What are the red flags in a commercial HVAC maintenance contract in Toronto?

Accepted Answer

Key red flags include: no defined visit schedule, no written reports after visits, coil cleaning excluded or listed as an add-on, no priority emergency response clause, auto-renewal with undisclosed price escalation, truck charges and fuel surcharges not disclosed upfront, and no clear definition of what parts are included versus billed separately.

Question 4

How often should commercial HVAC systems be serviced in the GTA?

Accepted Answer

Every commercial HVAC unit in the GTA should receive a minimum of two seasonal maintenance visits per year — a spring cooling startup in April or May and a fall heating commissioning in September or October. Higher-use buildings and buildings with critical uptime requirements should have quarterly visits.

Question 5

Is it worth paying more for a higher-quality HVAC maintenance contract in Toronto?

Accepted Answer

Yes. The cost of one avoidable compressor failure ($4,000-$12,000) exceeds the annual cost of a properly-scoped maintenance program for most GTA commercial buildings. A contract priced 30% below market is almost always cutting scope, visit frequency, or technician credential level to hit that price.

Question 6

What certifications should a commercial HVAC maintenance contractor have in Toronto?

Accepted Answer

Verify: Local 787 United Association journeyman certification, TSSA G1/G2 gas fitter licensing, A2L refrigerant handling certification, current WSIB coverage, and $5M+ commercial general liability insurance. Avetta Safety Star and BBB+ accreditation are increasingly required by institutional landlords and REITs for contractor prequalification.

Question 7

What is the ROI of commercial HVAC preventive maintenance?

Accepted Answer

Every dollar invested in commercial HVAC preventive maintenance returns four to six dollars in avoided emergency repair costs, extended equipment life, and reduced energy consumption. For a building spending $60,000 annually on HVAC operations, a well-executed maintenance program typically saves $15,000-$25,000 per year.

Question 8

What should I look for in a commercial HVAC company for a multi-residential building in Toronto?

Accepted Answer

For a multi-residential building in Toronto, prioritize: 24/7 live dispatch with under-4-hour emergency response, experience with your building type and equipment age, transparent pricing with no hidden truck charges or fuel surcharges, written maintenance reports after every visit, and full-service scope covering HVAC, plumbing, and building automation under one agreement. Ask for proof of Local 787 union certification, TSSA G1/G2 licensing, and Avetta or BBB accreditation.

Question 9

How is choosing a commercial HVAC company different for a multi-residential building versus a Class A office tower?

Accepted Answer

Multi-residential buildings require HVAC companies with hands-on experience in aging hydronic systems, mixed-vintage rooftop units, and complex older infrastructure. Response speed and pricing transparency matter more in multi-residential management where property managers are directly accountable to building owners for both tenant satisfaction and operating costs.

Question 10

What certifications should a commercial HVAC company have in Ontario?

Accepted Answer

Minimum certifications to verify: Local 787 United Association journeyman certification, TSSA G1/G2 gas fitter licensing, A2L refrigerant handling certification (mandatory for new equipment in Canada as of 2026), current WSIB coverage, and $5M+ commercial general liability insurance. Avetta Safety Star and BBB+ accreditation provide additional verified credibility for GTA property managers.

Question 11

How much does a commercial HVAC company charge for emergency service in the GTA?

Accepted Answer

GTA commercial HVAC emergency service typically costs $180-$280/hr during business hours and $240-$500/hr after hours, plus truck charges of $0-$125 per visit. Some companies add fuel surcharges of $15-$40 per call. Kontrol Buildings charges low truck fees and no fuel surcharges, with all pricing disclosed upfront.

Question 12

Is it better to use one commercial HVAC company for all building services or separate contractors?

Accepted Answer

One full-service company is almost always better for commercial and multi-residential buildings. A single provider handling HVAC, plumbing, building automation, and backflow testing under one agreement means one point of contact, one accountable team, faster emergency coordination, and typically better pricing through volume.

Question 13

What is Avetta certification and why does it matter for GTA property managers?

Accepted Answer

Avetta is a third-party contractor prequalification platform used by major property management companies and REITs to verify contractor safety, insurance, and compliance standards. Avetta Safety Star certification signals that a commercial HVAC company has been independently verified to meet institutional safety and compliance standards. Many major GTA property management companies require Avetta prequalification before engaging any contractor.

Question 14

How often should HVAC be serviced in a commercial or multi-residential building in the GTA?

Accepted Answer

Every commercial and multi-residential HVAC unit in the GTA should receive a minimum of two seasonal maintenance visits per year — a spring cooling startup in April or May and a fall heating commissioning in September or October. Higher-use buildings and buildings with aging equipment should have quarterly visits.

Question 15

What is the difference between a commercial HVAC company and a residential HVAC company?

Accepted Answer

Commercial HVAC companies are equipped for larger, more complex systems — rooftop units, make-up air units, hydronic systems, chillers, cooling towers, and building automation — in buildings with multiple tenants, compliance obligations, and 24/7 operational requirements. For any commercial or multi-residential building in the GTA, always engage a company with documented commercial building experience and institutional certifications.

Question 16

Are there energy incentives available for HVAC upgrades in GTA commercial buildings?

Accepted Answer

Yes. Enbridge Gas Save on Energy, Canada Greener Buildings grants, and IESO programs offer significant incentives for qualifying commercial and multi-residential HVAC upgrades in Ontario. Kontrol Buildings has secured over $2.5M in incentive funding for GTA commercial building clients.

Question 17

What are the red flags when evaluating a commercial HVAC company in the GTA?

Accepted Answer

Key red flags include: no defined emergency response time commitment, inability to disclose truck charges and fuel surcharges upfront, no written reports after maintenance visits, as-needed maintenance with no defined schedule, inability to provide certification documentation on request, and auto-renewal contracts with undisclosed price escalation.

Question 18

How much does a commercial HVAC maintenance contract cost in Toronto?

Accepted Answer

Commercial HVAC preventive maintenance contracts typically range between $5,000 and $30,000 per year depending on building size and HVAC system complexity. However, the stated contract price is often not the real cost. Property managers should be aware of hidden charges and add-ons — truck charges billed separately, fuel surcharges added to every call, coil cleaning excluded and billed additionally, and parts markup not disclosed upfront. Always ask for a fully itemized contract before signing.
