At the centre of your commercial business environment is the HVAC system, controlling the air quality indoors to keep everyone healthy, happy and work moving smoothly. But what is commercial HVAC and why is it so important?

Understanding HVAC

HVAC stands for Heating, Ventilation, and Air Conditioning. It is defined as technologies and systems that help control the temperature, humidity and quality of the air in the interior of a building. Residential HVAC systems are built for single-family homes, while the commercial version is built for larger buildings, such as office buildings, retail stores, restaurants and industrial facilities.

Key Components of Commercial HVAC Systems

  • Heating: This is the unit contributing to the production of warmth during winter months, through boilers, furnaces and heat pumps. Due to their scope, IE, heating massive spaces, commercial heating system are generally built with a view to using superior tech, including heating systems based on internal sub-units that individually optimize performance, as well as the ability to distribute heat in a homogeneous way.

  • Ventilation: Ventilation is the process of exchanging or replacing air in any space to remove unwanted odours, moisture, smoke or heat. Measures such as opening windows may be used to provide some ventilation, but for larger commercial buildings, a mechanical system of fans and air ducts is required.

  • Air Conditioning: In the summer, air conditioning systems cool the air inside the building. In commercial buildings the air conditioning systems are well-designed and powerful. They can maintain comfortable temperatures in large, well-attended areas. The systems are often large and incorporate features such as zoning the indoor areas, allowing it to selectively control the temperature in one area of the building separately from another.

Types of Commercial HVAC Systems

  • Multi-Split System: This is similar to single split systems, only that there are two or more indoor units connected to one outdoor unit. It is favourable when there are multiple rooms or zones in a building.

  • Variable Refrigerant Flow (VRF) System: Super efficient and flexible, it can simultaneously heat up and cool down different zones. This system is suitable for medium to large buildings with greatly differing heating and cooling requirements.

  • Rooftop Units (RTU): Installed on the roof of large commercial buildings, these can serve both as a heating or cooling system. RTUs are low maintenance and not a use of indoor space.

  • Chilled Water Systems (CWS): CWS include tubes filled with chilled water, used to cool large spaces in big facilities such as hospitals and universities. The system is highly efficient and can cool down large spaces.

Why Commercial HVAC is Essential

  • Comfort: the HVAC (heating, ventilation and air conditioning) system helps keep indoor temperatures comfortable and consistent, which in turn helps employees be productive and customers happy.

  • Air Quality: Ventilation and filtration devices improve air quality, removing allergens, odours and pollutants.

    • Great for: People with asthma or allergies.

    • Especially useful for: Behaviour change – more time outside also means greater activity and sunlight exposure.

  • Efficiency: Modern commercial HVAC systems are highly efficient in their operations, leading to reduced energy consumption and reduced environmental impact and operating costs.

  • Reliability: The HVAC has to work when there are people in the building. People can get sick if it doesn’t. They might shut the business.

Maintenance and Upkeep

To ensure the satisfactory and long-lasting operation of commercial HVAC systems, regular maintenance is essential.
