Commercial HVAC Services in Ottawa
Heating, Cooling and Ventilation for Ottawa Businesses
When the heat goes down in a house it is uncomfortable. When it goes down in a restaurant or a retail unit it costs money by the hour. Just Air works on commercial heating, cooling and ventilation for Ottawa businesses, from a single rooftop unit over a storefront to multiple systems across an office floor. We answer the phone 24 hours a day, 7 days a week, 365 days a year. Call (613) 266-9742.
Just Air
Commercial HVAC in Ottawa and the Surrounding Areas
We are a family owned and operated company, which on the commercial side means you deal with the same people every time rather than a rotating call centre. Our technicians are licensed and gas certified, and the same standards we apply to residential work apply to a rooftop unit at eight in the morning in February. We serve businesses across Ottawa, Nepean, Kanata, Stittsville, Barrhaven, Clarence-Rockland and the surrounding areas.

downtime
Emergency Response for Businesses
Commercial downtime is measured differently. A failed rooftop unit in July empties a dining room. A dead heater in a warehouse in January is a staffing problem within the hour.
Our line is answered around the clock, every day of the year, and emergency commercial calls are treated as emergencies. When you call, have this ready and it will save real time:
- The address and how a technician gets roof or mechanical room access.
- Make, model and serial number if you can reach the data plate safely.
- What the equipment is doing, and what it was doing before it stopped.
- Any error code showing on the controller.
- Who on site can authorise the repair.
More on after-hours work on our 24 hour emergency HVAC page.
maintenance
Planned Maintenance Beats Emergency Calls
Almost every commercial emergency we attend was visible months earlier. Belts, contactors, filters, drains and coils give plenty of warning if somebody is looking.
A scheduled maintenance visit covers the equipment before each season, catches the parts that are on their way out, and gets the work done at a time that suits your business instead of at 2am on a long weekend. It also keeps manufacturer warranties intact, which matters on newer rooftop equipment.
Tell us what equipment you have and how your business runs, and we will put together a schedule that fits. Call (613) 266-9742 or send us a message.
for customers
Frequently Asked Questions
Do you service commercial HVAC in Ottawa?
Yes. We work on commercial heating, cooling and ventilation for businesses across Ottawa and the surrounding areas, including rooftop units, commercial furnaces, make-up air, ductless systems and commercial water heating. Call (613) 266-9742 and describe the equipment and the site.
Do you offer after-hours commercial service?
Yes. Our line is answered 24 hours a day, 7 days a week, 365 days a year. Commercial downtime costs money by the hour, so after-hours calls from businesses are treated as emergencies rather than queued to the next working day.
How much does commercial HVAC service cost?
It varies far too much to publish a useful number. A filter and belt service on a small rooftop unit and a compressor failure on a larger one are different jobs entirely. Call us with the equipment details and the site address and we will give you a real figure rather than a placeholder.
Can you take over maintenance on equipment somebody else installed?
Yes. We service equipment regardless of who installed it. On the first visit we document what is on site, note the condition, and tell you honestly what needs attention now versus what can wait.
Do you work on rooftop units?
Yes, packaged rooftop units are common commercial work for us: seasonal service, repair and replacement. We need safe roof access arranged, so let us know how a technician gets up there when you book.
What size of business do you work with?
Mostly small and mid-sized commercial spaces: offices, retail units, restaurants, clinics and light industrial. If your site is larger or more specialised, call and describe it. We would rather tell you it is outside our scope than take on work we cannot do properly.
