Maintenance for residential homes operates on a straightforward schedule: it needs to happen twice a year, once in spring to attend to the air conditioning system, and once in fall to attend to the heating system.
This basic biannual schedule doesn’t work for many commercial and industrial facilities, however, for several reasons:
- The equipment in commercial and industrial facilities undergoes more work because it must handle comfort and process needs for a large area and a larger number of people.
- Because heating and cooling equipment aren’t used only for comfort, they often run during what is considered the “off-season” for a home. Heating and cooling are often necessary around the year to protect equipment and to facilitate the process. There’s little downtime for HVAC equipment.
- The types of HVAC equipment used in commercial and industrial facilities are much different than residential ones, including systems such as infrared radiant heaters, unit heaters, and make-up air units. These systems have different maintenance requirements.
Toronto frequently becomes hot and humid during the summer, especially in the latter half. This year is already setting heat records across North America, and we can anticipate some intense heat waves moving through in August and September. 
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.
What is the best thing you can have done for your 
You keep a close watch on the budget for your commercial facility, no matter the time of year. During the hot and humid Toronto summers, you expect to see an increase in energy usage in your facility because of the high energy demands from the cooling system. Keeping temperatures controlled inside a building is necessary for almost every type of business, whether it means providing comfort to the people inside or preventing damage to equipment and a slow-down in process. Even a medium-sized office space must have effective cooling for the server room or it will suffer from data loss.
If you’re reading this post, you probably think you could do better for your commercial facility when it comes to its cooling system. There are many reasons you may think this: perhaps higher bills, loss of revenue from equipment failing due to overheating, complaints from employees/clients/customers, or a general realization you have an HVAC system that’s old and outdated.
This is the time of year when commercial companies schedule a routine visit from a commercial HVAC contractor to take care of the pre-summer check-up and tune-up for their equipment. The stresses of the upcoming season make it necessary for HVAC machinery to be in top shape.
No one needs to tell you the winters in Toronto are rough. If you’re a business owner, you know the strain the temperatures and other conditions put on your facility over the season. You don’t want this strain extending into the rest of the year, particularly the heat of summer. Much of the HVAC system for a commercial facility runs throughout the year and doesn’t receive a “break” when temperatures warm up. This is why regular spring commercial HVAC maintenance is essential each year.
