Improve Your HVAC Energy Efficiency with an HVAC Expert

Heating, ventilation and air conditioning systems (HVAC) are great for regulating the temperature in a room or building. However, it cannot be denied that HVAC systems use up way too much energy. According to the NSW Department of Planning, Industry and Environment, HVAC electricity consumption could take about 40% of total building consumption and around 70% of base building electricity consumption.  

Regularly maintaining your HVAC systems by your local HVAC experts helps make them more energy efficient. 

Below are some simple things your HVAC systems specialist can do to help make your HVAC system more energy-efficient.

1. Optimise Your Chiller

If you have a chiller in your building, have it serviced at least once a year. Not only will the HVAC expert get to clean it, they will also check its entire system to make sure all parts function properly. This is especially crucial with chillers because often, they are not regularly serviced. The maintenance service will also include checking for signs of damage or other issues to ensure that your chiller is in good condition.

2. Make Sure Pumps Are Unblocked

Pumps are still important parts of HVAC systems. They are responsible for circulating the water throughout the pipes so that the HVAC system can remain functional. If the water flow is lower than expected, then your building will feel warmer than it should. This is because the water has to heat up to the temperature of the air to transport heat throughout the building. Therefore, the water has to be the same temperature as the air.

3. Clean the Air Filter

This is perhaps the most underrated maintenance step. Without air filters, the air conditioner cannot work as well as it should. And cleaning the air filter regularly will keep the air conditioner running more efficiently. An HVAC maintenance service will check this regularly.

4. Change the Valves on the Compressor

Valves on older HVAC system models are more likely to take up more energy compared to the newer ones. If you have an older HVAC system, replace the older valves with electronically controlled expansion valves. By doing this, you can increase energy efficiency by as much as 20%.

5. Regularly Check Boilers

The boiler should also be checked regularly because it is responsible for heating the water in the HVAC system. It is often overlooked, even though it is one of the most important parts of an HVAC system. And by checking it regularly, you can ensure that it is operating as best as possible.

6. Clean the Heat Exchange Coils

Heat exchange coils are responsible for transferring the heat from the water to the air. When these coils are blocked, the air conditioner will not be able to cool the room. This will result in the air conditioner running for a longer time. By regularly cleaning these coils, you can make sure that the HVAC system is not using too much energy.

7. Always Check for Leaks in Valves

Excessive water leaks can make an HVAC system lose a lot of energy. Even if you are not using your HVAC system to its full capacity, you can still waste a considerable amount of energy because of these leaks. Therefore, check your HVAC system regularly for any leaks that might be causing it to lose energy.


Maintaining HVAC systems is very essential to ensure it is as energy efficient as possible. By regularly inspecting the system with an HVAC expert, you can find problems before they become severe. That way, the problems could be repaired them before they become a major issue. Keep in mind that the above are only a few tips on how an HVAC expert can maintain your HVAC system.
