Thermostats should be set between 21-24°C in cooling mode and between 18 -21°C in heating mode. Every degree outside those bands can increase running costs by up to 15%.
If there is a hot day forecast, then pre-cool your house the night before. This is especially effective if your house has a high thermal mass such as solid brick. This will allow your air conditioner to work at its optimum during the cool evening, saving power and wear and tear on the unit. It also allows the unit to keep on top of the heat load as it begins to warm up during the heat of the day.
The process of cooling air involves the secondary process of dehumidification. Moisture is removed from the air when it comes into contact with the cold air conditioning evaporator coil. This moisture condenses, then runs off the coil , down the drain tube and outside to waste. This process is perfectly normal and the amount of water /condensate is dependent on the initial moisture content in the ambient in the space being cooled.
Regular filter maintenance helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to clean filters regularly to ensure proper air flow and to keep your house or office free from dust, allergens and germs. Depending on the type of filter you have, you may require filter replacement once a year.
Evaporative coolers:
The newer ones self drain but they still need flushing periodically and the pads also require changing when they begin to rot. They also need the water distribution cleaned or you can lose cooling due to the pads drying out.
Refrigerated Air Conditioners:
The return air filters require cleaning. The frequency depends on how dusty the house is. If not cleaned the unit can ice up and stop working. They also need the condenser (outside radiator bit) dust free with an unobstructed air flow. This can be cleaned by brushing in the direction of the fins or blowing it out using compressed air. Ensure the drain outlet is unrestricted. Wipe the surface of the inside unit down at regular intervals as they do gather dust
Gas Heaters:
Just like air conditioners some heaters have return air filters which require cleaning regularly. If a filter is not filled a general clean of the return air (where the air is drawn in the house) will be required. A service and carbon monoxide test should be done every 24 months
Air conditioning systems that require recharging of refrigerant on a regular basis are leaking and need repair. Leaking refrigerant not only causes your unit to lose cooling capacity and use more energy, it’s also very bad for the environment. Refrigerant gases released into the atmosphere are one of the worst culprits in depleting the ozone layer and causing greenhouse. A thorough leak testing procedure will need to be carried out to find leak and fix prior to system being reinstated for operation.
Regular servicing, cleaning filters, and using programmable thermostats can help reduce energy consumption.

Heaters and air conditioners are given star ratings for their performance – however there are often two sets of stars to look at: blue stars that rate cooling efficiency, and red stars assess heating.
With more stars to take into account, air conditioners can be trickier to select (even once you’ve determined that you’re weighing up similar models). The real key here is to look at both the stars AND the numbers that go with them.
There are two numbers you’ll need to look at:
Capacity Output kW (which lets you know the amount of cooling and heating the model can produce)
Power Input kW (which tells you how much power it needs to run). These numbers essentially tell you how much bang you’re getting for your energy buck, and they help explain the number of stars a product has earned.
As a rough rule of thumb when comparing star rating .. Every star will provide a energy saving of 10%… So a 5 star unit is 20% more efficient than a 3 star unit
In cooling mode, a refrigerated air conditioner absorbs heat from the indoor air and transfers it outside, via the refrigerant gas in the pipes connecting the indoor and outdoor units. The outdoor unit rejects the heat and pumps the refrigerant back to the indoor unit where the cycle continues. In heating mode, the process is simply reversed, to absorb heat energy from the outdoor air and sends it indoors (yes, even in cold weather there’s some heat energy in the outdoor air).
Oh no!! Have you been cleaning the filters on the air conditioner frequently??
A blocked return air filter or drain tube is usually causing the water to build up beyond the capacity of the drain and overflow. Not only is this a mess to clean up but water in the proximity of electrical equipment is also a safety risk.
Carbon monoxide is an odourless, colourless and tasteless gas. It is often called “The Silent Killer” because it is almost impossible to detect with your own senses. It is a by-product of the combustion process that happens when fuel is burned. It’s common in many home appliances.
Carbon monoxide poisoning happens when you or another individual has inhaled too much carbon monoxide. It can happen quite suddenly, and the symptoms include the following:
- Headaches
- Fatigue
- Dizziness
- Drowsiness
- Nausea
If you or someone else is experiencing carbon monoxide poisoning symptoms, immediately turn off any and all gas-burning appliances! Open windows and doors and exit your home right away.
Ongoing scheduled maintenance of gas heaters will reduce the possibility of carbon monoxide poisoning through faulty equipment. Heaters should be serviced at intervals not encoding 24 months
Air conditioners and reverse cycle systems use a refrigerant gas (commonly R32 or R410A) to cool or heat the air. These gases are sealed within the system and are not harmful during normal operation.
However, if there’s a leak due, the gas can escape. While modern refrigerants are low in toxicity, inhalation in high concentrations (especially in enclosed spaces) may cause dizziness or nausea. It can also reduce system efficiency and increase energy costs.
If you suspect a refrigerant leak, it’s important to turn off the unit and book a licensed HVAC technician immediately. We are fully qualified to detect and repair refrigerant leaks and safely regas your system according to Australian safety standards.
