If you are upgrading from an old, fixed-speed air conditioner to a modern Inverter system, you will see a drastic drop in your running costs. Old systems operate like a light switch—they run at 100% power until the room is cold, shut off completely, and then turn back on at 100% power when the room warms up. This causes massive power spikes.
Modern Inverter technology acts more like the accelerator in a car. It gently ramps up the power to reach the desired temperature and then dials back to a low, steady speed to maintain it. Depending on your usage, upgrading to a new inverter system can save you anywhere from 30% to 50% on your heating and cooling electricity costs.
