FAQs

Split systems are a cost-effective option for cooling or heating a single room or open area. They are efficient, quiet, simple to control and available in a wide range of sizes and brands. Lawson Air can supply and install split systems for bedrooms, living areas, apartments and small offices.

Ducted air conditioning provides whole-home comfort through discreet ceiling grilles. It can be designed with zones, smart controllers and different grille options to suit the home. It is a strong choice for larger homes, new builds, renovations and customers who want a cleaner look than multiple wall units.

Use blinds or curtains during the hottest part of the day, close doors and windows while cooling, clean filters, use ceiling fans to move air and set the temperature sensibly. If your system cannot keep up, it may be undersized, poorly maintained or due for replacement.

Turn the air conditioner off, protect nearby surfaces and check whether the filters are very dirty. Do not keep running the unit if water is leaking indoors. A technician should check the drain, coil, pipework and installation to find the cause.

Air conditioning can support indoor air quality by filtering dust and circulating conditioned air, but it is not a substitute for ventilation or cleaning. Dirty filters, mould or neglected systems can make air quality worse. Regular filter cleaning and servicing help keep the system working properly.

Regular servicing helps maintain efficiency, reduce breakdown risk, improve airflow and keep the system cleaner. It also helps identify small faults before they become expensive repairs. Servicing is especially important before summer and for systems used heavily through the year.

Start with the rooms you want to heat or cool, your budget, preferred brands, energy efficiency, noise level and installation constraints. For one room, a split system may be enough. For whole-home comfort, ducted may be better. Lawson Air can recommend suitable brands and capacities after reviewing your home or project.

A split system conditions one room or area using a wall-mounted indoor unit and an outdoor unit. Ducted air conditioning uses a central indoor unit, ductwork and ceiling grilles to condition multiple rooms or the whole home. Ducted systems can also include zoning and smart controls.

For most domestic systems, annual servicing is a sensible minimum and helps maintain warranty requirements. Systems in heavy use, commercial sites or dusty environments may need more frequent servicing. Clean filters more often between professional services.

The right size depends on room dimensions, ceiling height, insulation, window area, sun exposure, room use and local climate. A unit that is too small will struggle, while an oversized unit can short-cycle and waste power. Lawson Air can size the system properly before quoting.

A standard split system installation is often completed in one day, depending on site access, electrical requirements and the length of pipework. Ducted installations take longer to design and quote, but many residential ducted installs can also be completed quickly once approved and scheduled.

Inverter air conditioners adjust compressor speed to match demand instead of repeatedly switching fully on and off. This helps maintain steadier temperatures, lowers noise and can improve efficiency compared with older fixed-speed systems.

For most homes, a summer cooling setting around 24°C to 26°C is a practical starting point. In winter, set reverse cycle heating to a comfortable but moderate temperature rather than pushing the system harder than needed. Small changes can affect running costs.

Clean the filters, keep outdoor units clear of leaves and obstructions, seal major air leaks, use zoning and timers, and service the system regularly. Choosing the correct capacity is also important. An undersized or oversized unit can waste energy and perform poorly.

Many air conditioners last around 10 to 15 years, depending on usage, installation quality, location and maintenance. Coastal conditions, heavy use and neglected servicing can shorten the life of a system. If repair costs are rising, Lawson Air can advise whether replacement is the better option.

Zoning divides a ducted air conditioning system into separate areas, so you can cool or heat only the rooms you are using. It can improve comfort and reduce wasted energy, especially in larger homes. Lawson Air can supply ducted systems with zoning controls and smart Wi-Fi options where suitable.

Water leaks can be caused by a blocked drain, dirty filters, poor installation, a damaged drain pan, frozen coil or other faults. Turn the unit off if water is leaking indoors and book a service. Continuing to run the system can damage walls, ceilings or electrical components.

Cooling-only air conditioning is designed for cooling. Reverse cycle air conditioning can cool in summer and heat in winter, making it suitable for year-round comfort. Lawson Air supplies both options, but reverse cycle systems are the most common choice for Australian homes.

No. Air conditioner installation involves electrical work, refrigerant handling, drainage and manufacturer requirements. It should be completed by licensed installers with the correct qualifications. Incorrect installation can cause poor performance, leaks, safety risks and warranty problems.

Common warning signs include weak airflow, warm air in cooling mode, unusual noises, water leaks, bad smells, tripping power, error codes or a sudden increase in running costs. Book a service if the issue continues after checking the filter and remote settings.

Refrigerant is the fluid inside the air conditioning system that transfers heat between the indoor and outdoor units. It must be handled by a licensed technician. If refrigerant is low, the system may have a leak and should be inspected before further damage occurs.

Yes. Reverse cycle and cooling air conditioners remove some moisture from the air while cooling. Many systems also include a dry mode for humid days. If your home still feels damp or clammy, the system may be undersized, poorly maintained or not suited to the space.

A smart air conditioner can be controlled through Wi-Fi, an app or a compatible smart controller. This can let you adjust temperature, set schedules and manage zones remotely. Lawson Air supplies and installs selected split and ducted systems with smart control options, including ducted zoning controls where suitable.

Usually, no. It is better to run the system when needed and use timers, scheduling or smart controls to pre-cool or pre-heat the room. For ducted systems, zoning helps avoid conditioning rooms that are not in use. The best approach depends on your home, insulation and usage pattern.

Energy ratings help compare how efficiently different air conditioners use electricity. A more efficient unit can cost more upfront but may reduce running costs over time. The right choice still depends on room size, insulation, sun exposure and how often you use the system. Lawson Air can help match the unit to the space, not just the label.

Set a sensible temperature, keep filters clean, close doors and windows while the system is running, use zoning where available and book regular servicing. For older systems, replacing the unit with a modern inverter model may also improve efficiency. Lawson Air can help compare repair, replacement and upgrade options.

Unusual noises can point to loose parts, debris, fan issues, refrigerant concerns, electrical faults or general wear. Turn the system off if the noise is severe, persistent or new. Lawson Air can arrange servicing or repairs to diagnose the fault before it causes further damage.

Light rain normally is not an issue, but during severe storms, lightning or unstable power, it is safer to turn the air conditioner off. Power surges can damage electrical components. If your system stops working after a storm, book a licensed technician to inspect it before using it again.

Ductless air conditioning usually refers to a split system or multi-split system that does not need ductwork. It uses an indoor unit connected to an outdoor unit, making it suitable for bedrooms, living areas, apartments, renovations and homes where ducted installation is not practical.

It depends on the size of your home, how many rooms you want to condition and your budget. A split system is usually a practical choice for one room or an open living area. Ducted air conditioning is better suited to whole-home comfort with discreet ceiling grilles and optional zoning. Lawson Air can assess your home and recommend the best option before quoting.
