Yes! Keeping your air conditioner clean ensures it runs efficiently and lasts longer. Here are a few simple maintenance tips:
Dust and dirt build-up can restrict airflow, so it’s best to clean or replace filters every few weeks during peak usage.
If you have a split system, make sure the external unit is free from leaves, dirt, or obstructions to maintain proper airflow.
To keep everything in top shape, it’s a good idea to have your air conditioner serviced professionally once a year.
Always check the manufacturer's guidelines for specific cleaning recommendations.
With energy costs on the rise in Australia, it’s certainly worth considering investing in an air conditioner with energy saving features. Energy efficient units could save you a lot of money in running costs, and are particularly worthwhile if you live in a fairly hot climate and need to run your AC often. Many Australians will run their air conditioners consistently throughout summer, and find that their energy bills are much higher as a result. To avoid a nasty bill shock at the end of the month, we recommend investing in AC's with better energy efficiency ratings.
Yes, evaporative coolers are a great option for many Australian homes, especially in dry inland regions. They’re energy-efficient, eco-friendly and provide fresh, filtered air. Unlike traditional air conditioners, they don’t use refrigerants, which makes them a more natural cooling alternative.
Heaters are usually considered to be very safe for your health, and will keep the winter chill away but for some people with allergies, respiratory issues and sensitive skin, heaters can cause problems. Heaters remove moisture from the air which can cause skin to feel dry and may lead to itchiness or a rash. It can also dry out the nasal passages which can cause nose bleeds. For some people, fans or convection settings can cause trouble for those who have allergies or asthma but for the most part they are very safe. It is important to remember that they get hot! It’s always essential to exercise caution to avoid the risk of burns. Those with gas heaters will want to make sure they are serviced regularly and ventilated properly. Leaking gas or poorly ventilated rooms can be a serious danger to your health. As long as you follow the correct safety directions of your heating unit, you’ll find they are very safe.
Oil filled heaters can be very cheap to run in smaller spaces, like bedrooms. They are designed to use full power when first switched on, but will switch off their heating element once the space around them has warmed up. In a space like a bedroom, they can be very cost-effective and keep the temperature at a warm, consistent level.
Split-systems are generally considered to be the cheapest type of electric heater to run, although that will depend on factors like the size of your unit, its energy efficiency rating, the temperature you set it to, how long you operate it for and the electricity tariffs you are subject to.
Evaporative coolers are less effective in high humidity because the air is already saturated with moisture, which limits evaporation. In humid conditions, a split system or portable air conditioner may deliver better results. Evaporative cooling works best in dry climates where evaporation can occur rapidly.
Oil heaters are relatively simple - they use a heating element to heat oil which warms and radiates heat around a room. They can be quite energy efficient in the right settings, but are known to consume more energy than other types of electric heaters, like split-systems. Most oil column heaters will be around 1500 watts, although some come with low energy settings. Whilst they are heating and the heating element is in use, they will consume energy. As the temperature climbs and gets warmer, the element will switch off. In a cold, drafty room, the temperature may fall more quickly and the thermostat in the heater will tell the element to switch back on in order to heat up the room - this will consume a lot more energy. To keep energy bills to a minimum, they are best used in smaller rooms where there is less air movement.
Portable air conditioners, whilst very convenient and affordable upfront, are not the most energy efficient option on the market. Most use quite a lot of power relative to their size and can quickly become expensive to run all the time. They are best used in smaller spaces over shorter periods of time, trying to cool your whole home with one will likely leave you with a big energy bill at the end of the month.
The choice between an evaporative cooler and an air conditioner depends on your climate and personal preference.
Evaporative Coolers work best in dry climates by using water to cool the air. They’re energy-efficient, eco-friendly, and help maintain indoor humidity.
Traditional Air Conditioners are more effective in humid environments, offering precise temperature control with cooling and heating options.
If you live in an area with high humidity, an air conditioner is the better choice. If you’re in a dry climate and want a lower-cost cooling option, an evaporative cooler could be the way to go.
Here are some tips to keep in mind if you’d like to keep your electricity bill to a minimum:
1. Ensure your home is properly insulated as this can increase the efficiency and effectiveness of your air-con
2. Clean your filters regularly
3. Use energy saving features
4. Keep your windows and doors closed
5. Keep your blinds and curtains drawn
6. Keep up with regular servicing of your unit
Evaporative coolers work by drawing in warm air and passing it through wet cooling pads. As the air moves through, it loses heat through evaporation and exits the unit as cooler air. They’re most effective in dry, hot climates and are popular for their low running costs and natural cooling methods.
To install a portable air conditioner in a push-out window, you'll need a secure window sealing kit or create a custom seal with plexiglass or foam board. The goal is to cover the open space and provide a hole for the exhaust hose to vent hot air outside. It’s important to ensure a tight seal to prevent warm air from re-entering the room.
Installing a split system air conditioner involves mounting the indoor unit, placing the outdoor compressor, and connecting them via refrigerant pipes and electrical wiring. This process requires a licensed technician to ensure proper installation, gas handling and system efficiency. DIY installation is not recommended due to safety and warranty concerns.
To reset a Fujitsu split system air conditioner, turn off the unit using the remote control, then switch off the power at the isolation switch or circuit breaker. Wait a few minutes, then turn it back on. This can help clear minor faults. If the error persists, refer to the manual or contact a licensed technician for servicing.
If you don’t have a traditional window, you can still vent a portable air conditioner through a sliding door, ceiling vent, or even a dryer vent. Some users create custom venting through a wall or use a drop ceiling panel. Proper ventilation is crucial for effective cooling and to avoid overheating the unit.
Portable air conditioners work by drawing in warm air, cooling it with a refrigerant system, and blowing the chilled air back into the room. The heat is expelled through an exhaust hose that typically vents out a window. They’re a convenient, plug-and-play option for cooling bedrooms, offices or rentals without the need for permanent installation.
Installation costs for split system air conditioners in Australia typically range from $600 to $1,200, depending on the complexity of the job, the type of wall or home structure, and how far the indoor and outdoor units are apart. Always use a licensed installer to ensure safety and compliance with Australian standards.
The cost of running your air conditioner will depend on the type and size of the air conditioning unit you’re operating in your home. Generally you can expect running an air con of medium size to cost you between $400-$500 a year* . These costs may increase if you are cooling larger areas or using your air conditioner to heat your home.
Energy consumption depends on the type, size, and efficiency of the unit, as well as how often it’s used. Models with higher energy star ratings are designed to use less power while still keeping your space cool. To cut down on running costs, look for features like eco-mode, timers, and inverter technology, which helps regulate power use more efficiently.
How much your air conditioner should cost will depend on a number of factors; like the type and how many units you're planning to purchase and install. A split system for instance may cost you just a few hundred dollars or up to $5000 or more if you’re planning to install several units around your home. How much you ultimately pay will depend on your unique requirements.
In many cases it can be cheaper to buy an air conditioner in the winter. Not only will you find discounts available on purchasing AC models, you’ll also find that many installers will perform work more cheaply. Many portable, window and reverse cycle air conditioner models come with heater settings to keep your home warm in the winter and eliminate the need for separate heating solutions in your home.
Depending on the installer and your home's layout, installing a split-system air conditioner can cost anywhere from $600 to over $1,200. This includes labour, basic materials, and electrical work. Some retailers may offer package deals that include installation with the purchase of select models.
A split system air conditioner has two main components: an indoor unit mounted on a wall and an outdoor compressor unit. They work together to cool or heat your space efficiently, making them ideal for living rooms, bedrooms and open-plan areas. Many models include reverse cycle technology, allowing for year-round comfort.
The best heaters for large, open spaces are those that are powerful enough to distribute heat evenly across the space. That means you’ll want to consider either a gas heater or a split-system air conditioner. Gas heaters are well known for their powerful radiant ability and can cover even more space when paired with a fan to help spread heat across the room. Split-system air conditioning is designed to blow hot air into a room and so they’re great for an open plan layout. Another option for smaller living areas is electric flame heaters which look like a fireplace and can bring a warm atmosphere to a space.
The best heaters for bedrooms are often said to be oil column heaters. They’re compact, quiet and affordable and great for retaining heat and keeping a room warm for many hours. Alternatively a quiet fan heater, panel heater or ceramic heater can also be a great option for a bedroom space.
The best portable air conditioner is one that suits your room size, insulation and layout. At Retravision, we stock leading brands like Dimplex and Omega Altise, offering models with features such as reverse cycle, built-in timers, and remote controls. Look for one with a high energy efficiency rating and the right BTU output for your space. You can explore our full range of portable air conditioners online.
Gas and reverse cycle heaters are usually the cheapest (and most energy efficient) systems to use in the long run. Split-systems are capable of evenly distributing air evenly throughout spaces large and small and have the added benefit of cooling in the summer. Gas heaters will use your gas connection to heat up and can help you save on energy costs.
The main disadvantage of an inverter AC is that they can be an expensive investment initially, although they will save you a lot in running costs. For some, the need to use a professional installer can also be off-putting.
Most air conditioners come with warranties ranging from 1 to 5 years, depending on the brand and model. Some manufacturers offer extended warranties on certain parts, such as compressors. It’s always a good idea to check the warranty details before purchasing to understand what’s covered.
There are a number of things you should look for when buying a new air conditioner. Firstly, you should consider the type of air conditioner and how much power it uses. Look at measurements like its energy efficiency rating and its dehumidification level, which tells you how much moisture it removes from the air. You should also consider features such as energy saving switches, check filter lights, oscillating vents, sleep modes, app control and timers - all of which can help you to control your energy usage. It’s also important to check out the manufacturing warranties on the models that you are considering.
Getting the right size air conditioner is crucial for both comfort and efficiency. Here’s a general guide based on room size:
Up to 20 m² – 2 to 2.5 kW
20–40 m² – 2.5 to 5 kW
40–60 m² – 4 to 6 kW
60–80 m² – 5 to 7 kW
80+ m² – 6 to 9 kW
However, other factors like ceiling height, insulation, and sunlight exposure can affect cooling needs. For a more precise recommendation, visit our Air Conditioner Buying Guide.
There are several types of air conditioners, each designed to suit different spaces and needs:
Split System Air Conditioners are a popular choice for cooling and heating individual rooms, split systems consist of an indoor unit and an outdoor compressor. They’re efficient, quiet, and great for year-round comfort.
