Air Conditioning Safety Tips for Summer: Expert Advice to Stay Cool and Safe

Whether you have a split or ducted system, regular maintenance is the number one way to keep it running efficiently and safely through summer. Over time, dust, dirt and debris build up inside the unit, forcing it to work harder and raising the risk of faults.

Book a professional service before the peak of summer. A technician will clean the filters and coils, check the refrigerant circuit and test the unit's electrical components. Preventative maintenance is a simple way to extend the life of your system and avoid bigger repairs later.

With ducted air conditioning, make sure your vents and return air grilles are not blocked. Obstructed airflow makes the system work harder, uses more energy and can cause components to overheat.

Keep furniture and curtains clear of vents. If you notice weak airflow or rooms that never quite cool down, have the ductwork inspected for leaks, blockages or damage.

An air conditioner is a high-powered electrical appliance, so any sign of an electrical problem should be taken seriously. Lights that flicker when the unit starts, buzzing or crackling sounds, a burning smell or a circuit breaker that keeps tripping are all warnings.

If you notice any of these, switch the system off and have it checked before you use it again. Do not try to open or repair the unit yourself.

Running your air conditioner at a very low temperature all day puts unnecessary strain on the system and drives up your power bill. A setting of around 22 to 24 degrees keeps most homes and workplaces comfortable without overworking the unit.

Timers, schedules and smart controllers help too. Letting the system ease off while you are out, then bringing it back before you get home, gives it a break without sacrificing comfort.

Dirty filters are one of the most common causes of air conditioning problems. They restrict airflow, make the system work harder to cool your space and circulate dust and allergens through your home.

For both split and ducted systems, check and clean your filters at least every three months, and more often during heavy summer use or if you have pets or live near a dusty road.

Your outdoor unit needs room to breathe. Plants, leaves, stored items or built-up dirt around it block airflow, reduce cooling performance and make the unit run hotter than it should.

Clear away leaves and debris regularly and keep a gap around the unit on all sides. A routine service includes a check of the outdoor unit for damage or obstructions.

The festive season often means guests, extra lighting and more appliances running at once, all while your air conditioner works overtime. Be careful not to overload power points and avoid running several high-draw appliances from the same circuit.

If your circuit breakers trip often or you are unsure whether your home's wiring can handle the load, have it checked by a licensed electrician before the busy season.

If your system is not performing as it should, do not wait for a complete breakdown. Strange noises, weak airflow, water leaks or uneven cooling all point to a system that needs attention.
