What to Consider Before Buying a New Air Conditioner
The right air conditioner depends on your space, not just the brand or the price. Here is what to weigh up before you buy.
Choosing an air conditioner involves more than comparing prices or picking a familiar brand. The right system needs to suit your space, cool it appropriately and fit the way you live or run your business.
If you are still deciding between system types, our guide to the different types of air conditioners explains the main options. This post focuses on four things to consider before you buy: size, energy efficiency, installation and budget.
Consider the Size of the Space
Choosing the right air conditioner capacity for your space is essential for effective cooling and comfort. A unit that is too small may struggle to cool the room and run for long periods, while an oversized unit may cool the space too quickly and switch on and off more frequently than necessary, affecting comfort and efficiency. However, choosing the right size involves more than measuring the room. Factors such as ceiling height, sunlight exposure, window size, insulation, and open-plan layouts can all affect how much cooling is needed. The room’s purpose also matters, as kitchens, home offices with electronic equipment, and spaces with many people tend to generate more heat than bedrooms.
To ensure you choose the right unit, a qualified technician can assess these factors and recommend a suitable capacity rather than relying on general sizing estimates alone. If you are replacing an existing air conditioner, remember that the same capacity may no longer be appropriate, especially if you have renovated the space, installed new windows, or changed how the room is used.
Think About Energy Efficiency and Running Costs
When choosing an air conditioner, it is important to consider not only the purchase price but also the ongoing cost of running it. Electricity use can add up over the years, making energy efficiency an important factor when comparing different models. In Australia, energy rating labels use a star system to help buyers compare efficiency, with higher ratings generally indicating more efficient units of a similar size and type.
Features such as inverter technology and programmable timers may also help reduce energy consumption, depending on the model and how it is used. Before making a decision, check the product specifications and ask the supplier to explain any features you are unsure about. Keep in mind that your energy costs also depend on how you use the air conditioner and the conditions of your home, as poor shading and insulation can increase the amount of cooling needed. To make a more informed choice, ask the supplier for an estimate of the unit’s running costs based on your expected usage. Understanding how the estimate was calculated will help you compare different models more accurately and choose one that suits your needs and budget.
Consider Installation Requirements
Proper installation plays an important role in how well an air conditioner performs. The indoor unit should be placed in a location that allows cool air to circulate freely throughout the room, while the outdoor unit needs enough space around it for proper airflow. You should also consider practical requirements such as the electrical supply, the distance between the two units, access for future maintenance, and space for ductwork if you are installing a ducted system. If you live in an apartment or rental property, check with your body corporate or landlord first, as there may be restrictions on outdoor unit placement or modifications to the property.
To ensure safe installation and proper operation, always hire a suitably licensed technician. Noise is another factor worth considering, as both indoor and outdoor units produce sound while running. Choosing suitable locations away from bedrooms, living areas, and neighbouring properties can help minimise noise and make your air conditioning system more comfortable to live with.
Balance Your Budget With Long-Term Needs
When choosing an air conditioner, it is important to balance your budget with your long-term needs rather than focusing only on the initial purchase price. A cheaper unit may not offer the best value if it is unsuitable for your space or uses more electricity than expected. To make a well-informed decision, compare quotes based on the total cost, including the unit, installation, warranty coverage, expected running costs, and ongoing maintenance. You should also consider how long you plan to stay in the property and how often you will use the system. For example, investing in a more efficient unit may be worthwhile for a family home where the air conditioner runs frequently, while a more affordable option may be sufficient for a spare room that only needs occasional cooling.
Getting quotes from several providers and asking them to explain their recommendations can help you compare your options with confidence. Finally, remember to budget for regular servicing, filter replacements, and repairs that may not be covered by the warranty. Understanding what the warranty includes and how long it lasts can also help you avoid unexpected expenses in the future.
