In most cases, a standard bedroom 2.5kW wall split air conditioner for a room up to approximately 4m x 4m would cost from about $1,500. For an average lounge room up to approximately 6m x 7m, a 7.1kW wall split air conditioning system may be suitable, with pricing starting from about $2,500. These prices are an approximate guide. Factors such as sunlight, heat load, ceiling and wall insulation, installation access and the room layout can affect the system size and installation cost. Choosing the correct system helps maintain a comfortable temperature, improve energy efficiency and reduce unnecessary power consumption.

If you are looking to air condition your entire home with both heating and cooling, a ducted air conditioning system may be the best option. Adding smart Wi-Fi zoning and a touchscreen controller can provide greater control over individual areas of the home. Major brands such as Daikin, Fujitsu, Panasonic, ActronAir and Mitsubishi offer reliable ducted systems with different airflow, efficiency and control options. Smart zoning systems such as iZone can also use electronic bypass technology instead of requiring a permanent constant zone. This allows the system to focus heating or cooling on the rooms being used, helping reduce energy wastage.

A standard ducted air conditioning controller allows you to turn different zones on and off and control airflow to separate areas of the home. However, the system will usually control the temperature and operation of the outdoor unit using one central temperature sensor, commonly located in the wall controller or return-air grille. This can result in longer running times and higher energy use when you only want to condition one or two smaller zones.

A smart home controller can use individual temperature sensors within each zoned space. This allows the system to respond more accurately to the temperature in each room, improve comfort throughout the home and reduce unnecessary outdoor unit running time. Smart zoning is particularly useful when only a few zones are operating or when the home's heat load changes during the day as sunlight moves across different rooms.

AirTouch 5 is one of the leading smart air conditioning controllers for ducted homes. It allows you to control the air conditioner and individual zones using its touchscreen, smartphone app or a compatible voice assistant. Optional room temperature sensors can help maintain more consistent temperatures while avoiding unnecessary heating or cooling. iZone is another strong option for customers seeking broader smart-home control, including compatible lighting, appliances, blinds and irrigation.

Start by considering which rooms need heating and cooling, how many spaces will operate at the same time, your available budget and any installation limitations. Correct system sizing should account for floor area, ceiling height, insulation, window area, sun exposure, room use and the local climate. You should also compare energy efficiency, operating noise, zoning and Wi-Fi features, warranty coverage, local parts availability and ongoing servicing requirements.

Choosing an incorrectly sized or unsuitable system can increase installation and running costs, reduce comfort and shorten the life of the equipment. Contact Lawson Air for a professional site assessment so our team can calculate the most suitable system for your property.

A split system is generally a practical and cost-effective choice when you only need to condition one room or a main open-plan living area. Split systems are efficient, quiet and relatively simple to install. However, separate indoor units may be required when conditioning multiple rooms, which can increase installation, running and maintenance costs.

Ducted air conditioning is better suited to customers seeking discreet whole-home or multi-room heating and cooling. Optional zoning and smart controls can allow different areas to operate independently. Your choice should depend on the number of rooms involved, the home's layout, available ceiling space, installation access and budget.

Most residential air conditioners should receive professional servicing at least once each year. Annual servicing helps maintain airflow and efficiency, reduces the likelihood of breakdowns and may be required under some manufacturer warranty conditions. Systems used heavily throughout the year, installed in dusty or coastal environments, or operating in commercial premises may require more frequent maintenance.

Filters should also be inspected and cleaned regularly between professional services rather than waiting until the annual appointment. If you are unsure when your air conditioner was last serviced, or it has been more than 12 months, contact Lawson Air to arrange a service and system check.

The longest air conditioning warranties currently available through Lawson Air are seven years for eligible residential systems. Hisense and TECO offer seven-year warranties on selected split, multi-split and ducted systems, subject to the applicable product, installation, registration and promotional conditions.

Most other major brands provide five-year residential warranties, including Daikin, LG, Mitsubishi Electric, Mitsubishi Heavy Industries, Fujitsu, Panasonic, Samsung and Carrier. Warranty periods can vary between residential and commercial applications, product ranges and promotions, so you should confirm the warranty conditions for your selected model before purchasing.

It is also beneficial to choose an installer that is recognised by the manufacturer as an authorised service and warranty agent. Lawson Air is a service and warranty agent for Daikin, Mitsubishi Heavy Industries and Rinnai. When an eligible issue falls under the manufacturer's warranty conditions, our team can deal directly with the manufacturer and complete authorised repairs. This can streamline the warranty process and reduce delays caused by waiting for a separate authorised service agent.
