Frequently Asked Questions
How does Evaporative Cooling work?
Hot air enters the cooling unit (usually located on your roof) where it is filtered and cooled as it passes through specially designed and moistened pads, this process then allows the fan to blow beautifully cooled air throughout the home.
How often do I need to change the filter pads in an Evaporative Cooler?
The average life span of an evaporative cooling pad is dependent on how often and for how long the cooler is used as well as the quality of the water supplied. Hard water areas will generally lead to a shorter lifespan as the water leaves a larger number of solids and calcium behind during the evaporation process, which in turn leads to a restriction of airflow through the flutes of the pads.
How often should I clean the return air filter?
As a general rule of thumb, you should clean your return air filter every 3 to 4 months (roughly once a season). It is critical as it maintains Energy efficiency & Lower Bills: When a filter is clogged with dust, your heater has to work twice as hard to suck air in through the return grille. This restriction strains the fan motor and forces the system to run longer cycles, which spikes your gas and electricity bills.
Protects the System from Overheating: Gas ducted heaters rely on constant, steady airflow to keep the internal heat exchanger at a safe operating temperature. If a dirty filter severely blocks that airflow, the heat exchanger can overheat, causing the system’s safety switches to trip and shut down the heater entirely.
Prevents Component Damage: Chronic overheating caused by a blocked filter places massive stress on the heat exchanger. Over time, this constant expanding and contracting from extreme heat can lead to micro-cracks—which can completely ruin the unit or create a safety hazard.
Improves Indoor Air Quality: The return air grille is responsible for filtering out dust, pet dander, hair, and airborne particles. Once a filter is completely saturated, it can no longer trap these contaminants, allowing them to recirculate right back into your living spaces.
What is a ducted split system and how is it different from a wall hung split?
While a wall-hung split system is designed to heat or cool a single, targeted room, a ducted split system is a whole-home climate solution. The indoor unit is discreetly concealed within your ceiling or floor cavity, distributing conditioned air seamlessly to multiple rooms through subtle ceiling or floor vents.While a wall-hung split system is designed to heat or cool a single, targeted room, a ducted split system is a whole-home climate solution.

What is "zoning" in a ducted system?
Zoning allows you to divide your home into separate sections (e.g., day zones like the kitchen/living area, and night zones like the bedrooms). Using a centralized controller, you can turn off conditioning in unoccupied rooms or set different temperatures for different zones, which significantly reduces energy consumption.
How often should a duct gas heater be serviced?
Industry standards and energy safety authorities strongly recommend having your ducted gas heater serviced by a licensed technician at least once every two years. Regular maintenance clears out dust buildup, ensures the burners are operating efficiently, and verifies that the system is safe.
What is Carbon Monoxide (CO) Safety Testing and why is it necessary?
Carbon monoxide (CO) is a completely colorless, odorless, and tasteless gas, making it impossible to detect without specialized equipment. If a gas heater is faulty, poorly ventilated, or has a cracked heat exchanger, it can leak CO into your home. A CO safety test uses specialized digital ambient detectors to ensure your heating system is 100% safe to operate. What are the physical symptoms of Carbon Monoxide exposure? As you cannot see or smell a leak, you must rely on physical warning signs. Early symptoms of carbon monoxide poisoning includes: unexplained headaches, dizziness, or confusion, nausea, fatigue, or flu-like symptoms that miraculously improve when you leave the house, Shortness of breath, Pets appearing unusually lethargic or unwell. How can I tell if my gas heater is at risk of leaking CO? While only a licensed gas fitter can guarantee safety, immediate warning signs can include heavy soot buildup or yellow/brown scorching around the heater panel or vents. A burner flame that is lazy, yellow, or orange (it should be a crisp, sharp blue). A heater that frequently shuts itself down or struggles to stay lit.
How the Government Rebate Scheme Works (VEU)?
Government HVAC rebate schemes—most notably the Victorian Energy Upgrades (VEU) program—are designed to help households and businesses transition away from high-running-cost or high-emission heating and cooling systems to energy-efficient electric alternatives. the scheme operates as an upfront, point-of-sale discount administered directly through licensed, accredited trade providers. The scheme applies to Victorian homes and must be at least 2 years old to qualify, brand new builds generally don't qualify).
How long should I expect my HVAC system to last?
While it depends on usage, environment, and how well the system has been maintained, the average lifespan is typically 10 to 20 years. Regular professional servicing is the best way to maximize this lifespan.
