Toronto’s first cold stretch isn’t the time to find out your boiler won’t fire, a rooftop unit has a weak ignition component, or the heat pump is struggling to switch into heating mode. After months of lighter use, commercial heating equipment can develop problems that aren’t obvious until it’s put back under load. Our team at Advantage Airtech Commercial Ltd. helps Toronto businesses inspect and test boilers, rooftop units, heat pumps, make-up air units, and other heating equipment before colder weather arrives.

Preparing Your Commercial Heating System Before Toronto’s Cold Weather Arrives
Wednesday, September 2nd, 2026Common Repair Issues With Rooftop HVAC Units
Monday, June 20th, 2022
Rooftop HVAC units are among the most frequently employed climate control systems for industrial and commercial facilities. The typical rooftop HVAC unit is a packaged system containing a compressor, expansion device, condenser coil, evaporator coil, and powerful blower fan. Unlike split systems, which place some of their components indoors (the air handler and one of the coils), a rooftop unit handles the heating and cooling in one unit and then sends the conditioned air down into the building’s ventilation system.
Rooftop units are advantageous for businesses because they remove all the bulky and noisy equipment out of the workspace and onto the roof. It’s easy for technicians to access them without disrupting workflow, and they’re modular to allow for a business to continue to expand. A well-installed rooftop unit can last for around 15 years.
However, any HVAC system can encounter repair issues. Below we’ve listed several common rooftop HVAC problems.
Signs of a Failing Compressor in Your Commercial HVAC Equipment

The most common types of commercial HVAC systems are refrigerant-based. The rooftop units that often provide climate control for commercial facilities operate using powerful compressors that put the refrigerant under pressure so it circulates to move heat from one location to another—either heating or cooling the interior. The compressor is the most important component of these commercial HVAC systems: it draws on the most power and it serves as the literal heart of the system. A failed compressor is a serious problem since the cost of replacing one often makes it more cost-effective to replace the entire HVAC unit instead.
If you know what to watch for, you may be able to detect a compressor that’s starting to fail and call for professional repairs in time to stop a bigger problem. Below we’ll look at some of these warning signs of compressor trouble.
Help Understanding Sizing of Commercial HVAC Units
Monday, February 28th, 2022
Commercial HVAC is a complex field that requires years of training and experience. Most business owners and commercial facility managers don’t have specialized knowledge of this field, and that’s the reason they rely on contractors like us for their commercial air conditioning and heating in Toronto, ON.
Some of the terminology used in commercial HVAC can sound confusing, and in this post, we want to help you get a better understanding of one of the most important parts of any HVAC unit installation: sizing.
Beware Refrigerant Leaks in Rooftop Units
Monday, November 23rd, 2020
Your facility probably uses rooftop units as an important part of its cooling and heating around the year. These packaged heat pumps operate through the circulation of refrigerant, which is necessary in both heating and cooling mode.
One of the major dangers you may face to your heating this winter is a rooftop unit that’s leaking refrigerant. Leaks are a reason to call us for commercial heating repair in Ajax, ON. We’ll explain below the danger of refrigerant leaks, how they can occur, and what we can do to correct the issues so your facility can get back to work.
Why Consider Rooftop Unit Installation for Your Commercial Heating
Monday, August 31st, 2020
When it comes to commercial heating installation in Ajax, ON and the Greater Toronto Area, our team is able to handle any job. Heating is a special challenge here in Toronto because of the long winters and heavy snowfalls. In fact, concern about snowfall is what often makes commercial facility managers feel hesitant about installing rooftop HVAC units to provide heating. The exposure to the elements makes it sound like a rooftop packaged unit is a risk.
But rooftop HVAC units are the most common way to provide climate control for facilities. You only have to look at buildings in Toronto to see all the units installed on the roofs of buildings. Why is the rooftop heating (and air conditioning) installation advantageous, and why do we do so many for our clients?
Industrial Rooftop Unit Maintenance Is a Spring Essential
Monday, April 13th, 2020When it comes to industrial HVAC in Toronto, ON, the transition from chilly winters to humid summers can put immense strain on rooftop units. Having properly operating rooftop HVAC units is essential for any industrial facility to maintain the temperatures and ventilation needed for process, comfort, and more. Since most of these packaged rooftop units are heat pumps, they operate in all types of weather.
But when the snows melt and the shift in the weather begins, it doesn’t mean rooftop units are suddenly having an easier job. Without professional maintenance and inspections to help during the transitional period, rooftop units can suffer damage and lose significant amounts of energy efficiency.
Snow and Rooftop HVAC Units
Monday, December 23rd, 2019
The most common type of commercial heating and air conditioning in Toronto, ON is the rooftop HVAC unit. This is true not only for Toronto, but throughout North America. Rooftop packaged systems are convenient, powerful, simple for technicians to access, modular for easy expansion, allow for a quieter workspace, and save room inside the facility.
When winter snows arrive in Toronto, however, it can mean trouble for rooftop units. If you’ve ever wondered how those exposed rooftop units make it through the snowfalls of the season, this is the post for you.
Rooftop Packaged Units Need Special Fall Maintenance
Monday, October 14th, 2019At Advantage Airtech, we place emphasis on regular maintenance for commercial and industrial heating systems. It’s not only that we understand how beneficial maintenance is for HVAC systems. It’s that we offer maintenance programs that go beyond what many commercial heating contractors in Toronto, ON offer. A maintenance program should fit a facility exactly, which a basic checklist maintenance program can never do. Each or our clients has a maintenance program developed for their equipment, and only dedicated technicians familiar with the equipment show up to handle the maintenance each fall.
This applies even to heating systems considered “standard” for commercial and industrial facilities, such as the rooftop packaged unit. These heating/cooling systems require special attention.
Leaking Refrigerant Can Endanger Your Heating
Monday, February 18th, 2019There are several ways to provide central heat to a commercial building. The most common one is the rooftop HVAC unit. These packaged heat pump are useful for providing both heating and air conditioning around the year, and because they are located on the roof, they are easy for technicians to work on without creating disruption in the facility space.
One of the bigger repair concerns with packaged HVAC systems is loss of refrigerant—and this can spell huge trouble for your winter heating! Leaking refrigerant requires prompt commercial heating repair in Toronto, ON or it may cause a complete failure.
