How To Go Green & Slash Your Energy Costs?

Does your home have a wall-split air conditioner? These air conditioners have the wall unit connected to an outdoor compressor via a refrigerant line though your home’s wall. Many Australians choose wall-split air conditioners as a cost-effective alternative to ducted air conditioning. Wall-split AC units are already energy-efficient compared with ducted ACs as they have no ductwork. Research shows that ductwork can be responsible for a large amount of wasted energy. Here are three “how-to-go-green” ways to reduce the cost of running your wall-split AC even further.How To Go Green

Tip #1. Carry Out Regular Cleaning

Wall split air conditioners can benefit from regular cleaning in order to maintain optimum energy efficiency according to research published in the Journal of Energy and Environment. The indoor wall-mounted unit has a lift-up front and two or more removable filters. Regularly removing and washing these filters once a week prevents the air conditioner from using more energy than it has to. Clogged filters will increase the amount of electricity that the fan motor uses to draw in air and circulate it around the room. Research carried out by the Faculty of Engineering, University of Malaya, Kuala Lumpur indicated that regularly cleaning the outdoor compressor unit is essential to minimizing the energy usage of the air conditioner. High-pressure washers effectively remove dirt from between the condenser fins and help the unit minimize its power consumption. Contact a local air conditioning firm in your area to help you clean your air conditioner regularly. Going green is a way of thinking.

Tip #2. Invest In Regular Servicing

Split air conditioners consist of an indoor- and an outdoor-unit, which are fixedly installed and linked together with the refrigerant line. They are already very energy-efficient as the condenser and the compressor are located in the outdoor unit and do not deliver any waste heat indoors. According to an article published by the Air Conditioning and Mechanical Contractors Association of Australia (AMCA), wall-split units can lose energy efficiency if they are not regularly serviced. It is essential to invest in a professional ‘tune-up’ of your AC unit to reduce the amount of energy that it wastes. Trained technicians can inspect the refrigerant line, top up the refrigerant if needs be and check that all electrical components are functioning correctly. This helps reduce the amount of electricity used by the unit.

Tip #3. Upgrade Your Air Conditioner

If you have a standard non-inverter air conditioner, you may be able to reduce your bills by replacing it with an inverter-type system. According to Topten International Services, ‘split air conditioners with a variable speed drive and a permanent-magnet motor are the most energy efficient air conditioners’. Inverter units can modulate the speed of the outdoor compressor fan from low to high. This gives your home a more consistent internal temperature. If your existing air conditioner is not an inverter model and is nearing the end of its useful lifespan, consider investing in an inverter AC unit.


Keeping your wall-split air conditioners clean and well-serviced are the best ways to minimize their electricity consumption. Don’t forget that you can find reputable air conditioning servicing by visiting the AMCA website and searching for a registered professional in your area.
