Effective climate control is essential for maintaining comfort in any indoor environment. This guide explores how commercial HVAC systems work, and how to optimise them for increased efficiency.
What is a Commercial HVAC System and How Do They Work?
Heating
is typically achieved through using boilers, furnaces or heat pumps.
Cooling
a building usually involves a process called refrigeration, wherein heat is extracted from the air indoors.
Ventilation
systems move fresh outdoor air indoors and filter it, while also expelling contaminated indoor air.
What is HVAC Optimisation?
What are the Benefits of Commercial HVAC Optimisation?
For example, many buildings currently try to maintain a target temperature by alternating their heating and cooling systems. An office building with a target temperature of 20 degrees Celsius may start by turning on their air conditioning to reach this target. However, the system is likely to overshoot the target, meaning the heating system will turn on to raise the temperature back up—which will also likely result in an overshoot.
This overshoot cycle results in temperature fluctuations within the building. This not only wastes energy, but can also cause significant occupant discomfort as temperatures remain uneven throughout the day.
In this case, technologies such as variable speed motors and BMS software can help heating and cooling systems maintain a consistent temperature without overshooting. Moreover, zoning, smart thermostats and sensors can minimise energy waste by only heating and cooling areas which are in use.
What Kind of Maintenance do Commercial HVAC Systems Require?
Cost Reduction
An efficient, well-maintained HVAC system uses less energy and thus costs less to run. high costs associated with overworked equipment.
Extending Equipment Lifespan
Preventive maintenance is important to reducing wear and tear on the system. Without it, typical issues such as clogged filters or malfunctioning parts force the system to work harder, which can cut its operational life.
Improving Air Quality
Indoor air quality can deteriorate when HVAC systems are neglected. Dust and allergens can accumulate in filters, coils, and ducts, affecting the air you breathe. Regular cleaning can prevent issues that affect both comfort and health.

What’s the difference between residential and commercial HVAC systems?
Residential and commercial HVAC systems differ in their design and function. Residential units are smaller, simpler, and typically placed around a home, while commercial systems are larger, more complex, and often installed on building roofs to save space and minimise noise. Commercial HVACs are modular, allowing for easier maintenance and upgrades, and require specialised equipment to handle larger spaces and more diverse environmental conditions.
