If you’re a building owner or a property manager, you know how important the commercial HVAC system is. Maintaining a comfortable temperature indoors year-round in commercial spaces is much more complicated than in smaller residential spaces, and if your building is too hot or too cold, it can have a negative impact on your business. Commercial HVAC systems must also regulate the humidity levels and filter and purify the air, removing bacteria and other contaminants and decreasing the opportunities for mold to grow. 

Additionally, if you don’t keep your commercial HVAC system well maintained, it can break down and cause major disruptions, not to mention major repair expenses. Rather than wait until an HVAC emergency happens, we recommend investing in regular maintenance from trusted HVAC installers to keep your system in top working condition. 

In this article our team will walk through the basics of commercial HVAC systems and how they work. If you have any questions please contact our team today. 

Warm or cool air

Heating

Most commercial HVAC systems heat the air using a burner, which creates combustion gas that is moved into a heat exchanger. When the air passes through the heat exchanger it warms up to the desired temperature and is then moved through your vents and into your building. Some commercial buildings use a hot water heating system where hot water is flushed through pipes in the floors, ceilings, or walls to heat the space. 

In large spaces like office buildings, schools and universities, or shopping malls, achieving equal heat distribution can be a challenge, and ensuring the space doesn’t get too hot during the colder winter months is essential. When it comes to commercial HVAC design, you need an installer who has many years of experience designing and installing commercial HVAC systems. 

Cooling

In order to cool the air, cooling systems work the same as heating systems except in reverse. Cooling systems remove the hot air from your indoor space and transfer it outside until the air inside has reached your desired temperature, and use water or air-cooled systems to moderate humidity levels. 

Keeping your space adequately cooled is essential for the comfort of everyone in your building, especially during the hot summer months. A good commercial HVAC system will keep your space from feeling hot and stuffy, and it will also filter and purify the air.

Distribution

The network of vents and ducts that runs throughout your building is how the hot and cold air will be distributed. For large commercial buildings with many rooms, like a museum or a shopping mall, it’s important to ensure that the ducts reach every part of the building to ensure equal air distribution. Otherwise you’ll notice hot and cool spots throughout, and your HVAC system may be working overtime, resulting in larger expenses for you.

For office HVAC installations and similar installations, the vents and ducts should be distributing hot and cool air to every part of your building, not only the areas with the most foot traffic. 

Controls

Do you know what type of controls you want for your HVAC system? Manual controls like thermostats allow you to alter the temperature throughout the day, and in commercial buildings the thermostats are in access-restricted areas where only you and other staff can reach them. 

Many modern commercial HVAC systems now use direct digital controls (DDCs) which operate using a centralized computer system. These controls allow you to monitor the entire building for any disruptions, malfunctions and other performance issues. DDCs also highlight where your HVAC system can perform more efficiently and save energy.
