Commercial air conditioning has become increasingly popular due to its numerous benefits in the workplace. Not only does it help reduce energy costs in building maintenance, but it can also create a more comfortable and inviting environment for employees and customers alike. It is commonly referred to as commercial HVAC; commercial heating, ventilation, air conditioning and cooling.
There are important factors to consider when selecting the best air conditioner for your building. There are also many different types of air conditioning available for a business; Wall Splits, Ducted Systems, Cassettes, Package Units (PAC), Multi-Heads, Air Handling Units (AHU), VRF Systems, and Chilled Water Fan Coil Units (CWFCU), just to name a few!
Here we’ll explore some of the common questions customers and business owners have with regards to commercial HVAC. In particular, the Why, How and What, as follows:
Why is Commercial Air Conditioning important?
Everything starts with a why. In the HVAC industry, business owners often ask why they need air conditioning. Is it required? If so, why is it important? What do I need to know?
With so many demands placed on commercial operations today, understanding the purpose of commercial HVAC allows proper assessment of it. With this understanding, a business owner can then fully consider how it fits into their business.
Commercial Heating, Ventilation and Air Conditioning (HVAC) systems are designed to support businesses in all areas. From legal compliance, to equipment performance and lifespan, to health and wellness of all who enter the building. These areas affect the business at all levels, from day-to-day operations all the way through to long-term success.
When considering the impact of commercial AC, it’s important to be aware of all types of people entering your business premise. Occupants and visitors to a business include:
- Family Members
- Vulnerable populations, and,
- Anyone else who may enter the building.
The list of air conditioning benefits is extensive, with positive flow-on effects to all areas of a business. Here we’ll outline just some of the main points when considering commercial air conditioning installation and use.
Indoor Air Quality (IAQ) & Comfort
Two primary goals of commercial HVAC systems are to maintain acceptable indoor air quality (IAQ) and provide thermal comfort. The different components of an HVAC system interconnect to achieve these key objectives.
Improve Indoor Air Quality
Commercial air conditioners include filtration and/or ventilation to keep the air free from dust and other pollutants that can make breathing difficult. This is especially true for those sensitive to allergies or with respiratory illnesses. Filters within commercial aircon trap harmful airborne particles as small as 0.3 microns so you can be sure your staff and visitors are breathing clean, fresh air every day.
Regular cleaning of the filters is important for optimal performance and pollution reduction to ensure that your business cooling system is working properly and cleaning the air effectively. If not properly maintained, the system can make people sick.
Air conditioning systems can also be used to introduce fresh air into a building, which can help maintain proper air pressure and quality. By circulating outdoor air into the building, it helps dilute any stale indoor air and ensure that the interior atmosphere is comfortable.
HVAC can ensure good airflow by removing musty smells and odours while introducing fresh outside air indoors. This helps keep the environment in the building healthy and clean with improved internal atmosphere.
Increase Comfort & Productivity
Creating a comfortable work environment in commercial spaces is essential for productivity and employee wellbeing. Commercial AC plays a key role in ensuring optimal temperature and level of comfort for all occupants.
Air conditioners also help to reduce the amount of moisture in the air (humidity), reducing the icky, sticking feeling you get on high humidity days. Humidity levels must be tightly controlled however, as low humidity levels can cause the indoor air to be too dry and increase the risk of certain health concerns. Optimal relative humidity level for an office building is between 35-55%.
Employees work better when they are comfortable, and air conditioning helps to maintain a comfortable temperature throughout the office. Commercial AC not only makes employees more productive, but also helps customers feel more comfortable while shopping or visiting your business. They will want to linger for longer, allowing more client interaction and spending.
Commercial HVAC can also helps improve health and happiness, both during and outside of work hours. On hot days, air conditioning prevents overheating so employees don’t get distracted or uncomfortable. This allows staff to concentrate and focus on getting the job done right. There are already too many distractions and discomforts in a typical work day – Aircon can help reduce some of these!
By providing an optimal working environment with suitable heating and cooling systems, businesses can ensure their staff remain positive and motivated with the job at hand. Some studies have shown that having adequate air-conditioning can even increase cognitive ability by 5%.
Positive Commercial Outcomes
Failure to install and maintain HVAC systems that are suitable for a building and the business within it can be disastrous. Positive outcomes that can be achieved with commercial air conditioning include, but are not limited to;
- Acceptable Indoor Air Quality (IAQ)

Commercial air conditioning systems are a key component of the built environment. Commercial AC helps to preserve structures and surfaces, support equipment performance, and save money on energy costs.
Built Environment Protection
Commercial HVAC keeps temperature and humidity levels within range for optimal human comfort and building maintenance. Air conditioners help to reduce the amount of moisture in the air by cooling the air and removing excess water vapour. High levels of humidity can cause mould and mildew to grow. This then creates an unhealthy environment that is detrimental to building structures and internal surfaces.
By controlling humidity levels within buildings, businesses can ensure safe conditions for not only staff but also the building itself. Humidity can cause damage to buildings in a variety of ways. With too much moisture, surfaces are prone to staining, wood and other organic material can rot, and mould and mildew may form. This can cause physical damage to walls, furniture, and other items in the building.
Commercial AC systems also help maintain the temperature of machinery and equipment, ensuring that it is operating at peak performance and efficiency. Investing in a reliable commercial AC system can save money in the long run by reducing expensive repairs and downtime.
Commercial aircon certainly helps business operations and reduce risk. While the presence of suitable equipment is important, maintenance of such equipment is just as important. This will in turn help to preserve your built environment.
Improved Efficiency & Energy-Savings
With commercial HVAC, businesses can significantly reduce energy costs by using energy-efficient air conditioning equipment. Many systems have sensors that detect when people are in the building and automatically adjust the temperature accordingly to maximize efficiency.
Some AC units have built-in thermostats that ensure temperatures remain constant, reducing energy waste. This helps to save natural resources as well as reducing carbon emissions.
Air conditioning can also have a positive impact on efficiency in the workplace by reducing strain on equipment and improving operational efficiency. By keeping the air temperature at an optimal level, air conditioners reduce stress on electronic equipment, as well as the people operating it. This results in less downtime and more output.
Smart AC systems also lead to reduced energy usage due to increased efficiency. As most office cooling systems are not running on full-power all the time, they require less energy to keep a space cool.

Failing to stay up to date with air conditioner maintenance may lead to unnecessary repairs, excessive energy consumption, and a range of negative business outcomes.
What are the Different Types of Commercial Air Conditioning available?
Finding the right AC system for your business is vital. Depending on the size and type of facility, there are several different types of commercial air conditioning out there that can provide the heating and cooling capacity you need.
Air Conditioning Method
Firstly, it’s important to understanding exactly what air conditioning is. Air conditioners work using the refrigeration cycle. This involves heat in the air being captured and transferred between indoor and outdoor using refrigerant.
When cooling, heat is removed from the indoor air and released outdoors. In the case of reverse cycle air conditioning, heat is transferred from the outdoor unit to the indoors.
In relation to cooling, the method of heat exchange with refrigerant can be conducted in two different ways:
- Centrally – Central AC Systems exchange heat with refrigerant in a central location (i.e. away from the area being cooled).
- Locally – Direct Expansion (DX) Systems exchanges heat with refrigerant at the point of air supply (i.e. in the area being cooled).
The decision between Central Air Conditioning and Decentralized DX Units is complex, involving various factors such as types, configuration, heat rejection options, applications, usage patterns, zoning, exposures, capacity control, environmental control, and temperature control.
Additionally, efficiency factors like fresh air ventilation control and energy monitoring need to be considered when comparing the two cooling methods. It is recommended to consult an experienced commercial or industrial HVAC contractor when examining central plant compared to DX units.
Central Air Conditioning
Central HVAC is an efficient, effective way to condition large spaces and many structures like high-rise offices, airports, schools, etc. It is often used when individual units in each room may not be cost-effective.
As outlined, central air conditioning refers to the source of cooling coming from a central location instead of near the air supply. Central AC systems serve multiple spaces from one base in a building. Cooling is typically distributed to fan coil units (FCU) via chilled water pipes.
The central air conditioning system consists of three subsystems: the chilled water plant, condenser water system/heat rejection system and air-delivery system. Heat is often removed from water using a chiller, which utilises the refrigeration cycle within it.
The evaporator components remove heat and condenser components transfer that heat to the condenser water (water-cooled chiller) or outside air (air-cooled chiller). Water-cooled chillers can use cooling towers in the condenser water portion. The chilled air resulting from the central AC system is typically delivered to room/s using chilled water fan coil units (CWFCU).
Direct Expansion (DX) Air Conditioning
These are typically used for single-level complexes, homes, and small buildings. There is a practical limitation to the length of refrigeration pipework, hence the use in smaller scale commercial buildings.
As outlined, direct expansion units cool air directly at the boundary of, or adjacent to, the room being conditioned. Refrigerant passes through a local cooling coil within the unit serving the area directly or via ducts.
DX units are best suited for air conditioning individual thermal zones. A thermal zone is a single area or group of areas within a structure that require similar indoor conditions. Thermal zones should be controlled individually to ensure optimal comfort and performance.
Each thermal zone typically requires its own dedicated DX air conditioning unit. This could apply to electronics-filled rooms with more heat loads than the rest of the office, meeting rooms with different occupancy levels throughout the week, treatment rooms in hospitals that require different conditions, and restaurant dining areas needing more moderate conditions compared to other areas.
Commercial AC Systems
Once the importance of air conditioning is appreciated, the individual business needs considered, and the method of cooling is assessed, the next step is to review the different types of commercial AC available.
Here are some of the popular commercial air conditioning system types:
Split System Air Conditioners
Split system air conditioners are ideal for businesses looking to keep a single room or area cool. They consist of two units which work together; one unit sits outside while the other is placed inside the building. Heat is transferred from one unit to the other using refrigerant, helping to reduce energy costs.
Indoor units typically sit on the wall (wall split systems), on the floor (floor-standing systems), on the ceiling (cassette type systems), in the ceiling (split ducted systems), or in a bulk-head (bulk-head units). Alternatively, a combination of these locations may apply to the one system as part of a multi-head system.
Packaged air conditioner units take up much less space than split systems as they contain all key components within a single unit. This makes them well suited for buildings that have limited space, such as high rises or apartments complexes. They make use of ducts and vents throughout the establishment to evenly distribute cool air.
VRF System Air Conditioners
Variable Refrigerant Flow (VRF) systems are becoming increasingly popular due to their energy efficiency and flexibility in cooling areas of various sizes. These systems use an outdoor heat exchanger and multiple indoor units which each control temperature in separate zones. This makes them ideal for large multi-room facilities like office buildings or warehouses that require separate temperature settings in each zone.
Regardless of what type of commercial facility you own, it’s important to understand the different types of commercial air conditioning available. This helps enable an informed decision when reviewing AC units for your business.
Commercial air conditioning can be a great way to keep a business premises comfortable, productive, and energy efficient. Commercial AC usually more critical than residential units and provides climate control for multiple rooms or areas with larger capacity in general. Commercial systems are typically custom designed to suit the size and usage of the building, making sure each room has the correct temperature, humidity, and airflow.
Investing in an energy-efficient air conditioner can help reduce energy costs and carbon emissions from a commercial building, as well as providing employees with a healthy work environment. Commercial AC is certainly a worthwhile investment to enhance customer satisfaction, productivity, equipment performance, profits, and overall business success.
