Emergency HVAC Repairs in Toronto: What Property Managers Should Do in the First Hour

Looking up at sky through office buildings downtown Toronto.
Office Buildings

An HVAC emergency is one of those rare events in a commercial or multi-residential building that really can be a minute-by-minute crisis. Tenant comfort and productivity may decline or stop immediately. If the breakdown occurs in extreme cold or heat, safety is at risk. An urgent call to an HVAC service contractor is an expense, but there’s often no choice.


The best way to handle an HVAC emergency as a GTA property manager is to have a calm, methodical “first hour” plan. Simple and effective action in the first 60 minutes can mean the difference between a fast resolution and a building-wide shutdown.


At Burban Air Systems Ltd., we recommend and install HVAC systems all over Toronto and the GTA. We have learned first-hand how quickly a panicked or uninformed approach to an HVAC emergency can drive up service costs into the thousands. But equally, an appropriate, well-planned, first-hour response can greatly improve the chance of a speedy repair.


Six Steps to Take When Your Building HVAC Breaks Down

Follow this first-hour action checklist for HVAC repairs or service in Toronto:


  1. Assess the Problem

The first critical minutes are for evaluating the type of breakdown you have:

  • No heating or cooling: Full building failure, usually a large component malfunction.

  • Partial problem: One floor, unit, or tenant only — zoning or controls issue is likely.

  • Odd noises, odours, or leaks: Possible electrical, mechanical, or refrigerant problem.


Note when the problem started, where and how many units are affected, and any warnings or events that preceded the issue.This information will help the HVAC service technician narrow down the cause quickly.


  1. Inform Tenants and Building Staff

Communication is key during the first hour of an HVAC emergency:

  • Let affected tenants know that the issue has been noted and technicians are on the way.

  • Inform building occupants in sensitive operations (restaurants, data centers, seniors’ housing) that actions are being taken immediately.

  • Brief the building staff (security, janitorial, concierge) so they know how to direct tenant calls and questions.

  • Tenants and occupants will generally be understanding if you communicate early and with confidence.


A short message and check-in will reduce tenant frustration and annoyance.


  1. Do a Visual Check Before Ordering Service

It’s also possible that what seems like a major emergency is actually a minor issue. In the first hour of an HVAC service call, quickly double-check the following before calling your HVAC service company:

  • Thermostat and BAS set points: Verify that temperatures or settings haven’t been changed by mistake.

  • Filters and air intakes: Restricted airflow is one of the most frequent causes of shutdowns.

  • Emergency shut-off buttons or switches: Make sure they have not been tripped.


❗Warning: Avoid technical checks or repairs and do not touch the HVAC equipment. Only perform, safe checks.


  1. Contact 24/7 Emergency HVAC Service

If your review confirms an HVAC issue or shutdown, call your emergency HVAC service company. 

Be ready to provide the following:

  • Address and access information: Building entrance, entry codes, elevator, and unit access.

  • The nature of the problem (sounds, smells, leaks).

  • Areas affected (whole building, partial, single unit). 

  • Steps you have taken. 


At Burban Air Systems Ltd., we have emergency response teams that cover the Greater Toronto Area 24 hours a day, seven days a week. We dispatch service technicians to your site immediately, often within the hour, to reduce repair and service time.


  1. Record the Issue

During that hour or more, start collecting information for your records and the service company.

  • Note tenant or staff calls and the times the issue was reported.

  • Photograph or video visible problems or conditions (water leaks, ice build-up, physical damage, etc. ). 

  • Record temperature and humidity readings (indoor and outdoor) and air quality, if you have those data points.

  • When the problem first occurred, these first-hour steps can pay off in big ways


Incident records not only help your HVAC service team troubleshoot faster but also provide you with a paper trail in the event of tenant disputes or insurance claims.


  1. Mitigate With Temporary Measures

In the case of a partial building or zone failure, depending on the tenant mix, consider some temporary mitigation steps:

  • Move-in portable heating or cooling units for vulnerable spaces.

  • Shut down or restrict use of the affected floor or unit until it is repaired.

  • Monitor tenant complaints (look out for seniors, children, or medical tenants especially).


Temporary measures can go a long way to limit complaints and liability, while more permanent repairs are under way.


The Importance of a First Hour HVAC Emergency Plan

The first hour is especially important in an HVAC emergency. During those 60 minutes:

  • A temporary problem can worsen into major damage.

  • Tenant complaints will spread by word of mouth.

  • Repairs may take much longer and cost significantly more.


By following a first-hour HVAC plan for troubleshooting, Toronto building managers and property owners can cut down on repair time and cost, avoid tenant escalations, and make the most of the emergency service call.
