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.

If you’re currently looking to install commercial or industrial HVAC equipment for your facility, you’ll immediately encounter the question of how powerful the equipment needs to be and how many units you’ll need to have installed to meet the climate requirements of the facility. In the HVAC industry, the job of determining the heating/cooling output requirements for new installations is called
This is a difficult question to answer in a standard blog because the type of business has a huge effect on control of temperatures and humidity. The range depends on whether the HVAC system is being used primarily to provide comfort to people inside the facility or if it’s designed to protect equipment and process. A large industrial space will need much different amounts of cooling during the summer than a small office space.
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
One of the most important commercial HVAC services we offer for our customers is cooling for a relatively small area of a facility. But it’s one of the most vital areas: the server room (also computer rooms and IT rooms).
You don’t want your commercial facility to suffer from any interruptions during the harsh Toronto winters because of a heating system failure. This applies to almost any type of commercial operation, from manufacturing to retail.
Although people connect the word “refrigerant” to devices that produce cooling, such as air conditioners and refrigeration equipment, refrigerant is often an essential part of the heating and cooling systems for commercial spaces. The standard rooftop units that most facilities use for climate control use refrigerant to both move into and out of the space. Under normal circumstances, refrigerant-based equipment will use the same charge of refrigerant through its service life—refrigerant circulates in a closed loop and does not dissipate through the heat exchange process.
We work with all types of
