Walk into a hardware store in the middle of a heatwave and you will see three very different machines all promising to cool the same room: a fixed split system,…

Two homes with the same aircon can pay very different amounts to run it. What really drives the cost, why the thermostat setpoint is the biggest lever, what star ratings do and do not tell you, and the free habits that lower the bill.

There is no single kW number that fits every room. What aircon capacity really hinges on, why an oversized unit short-cycles, when a rough guide is fine, and when to get a proper heat-load calculation done.

Your air conditioner does not make cold, it moves heat out of your house. A plain-English walk through the refrigeration cycle, why the outdoor unit blows hot air, why it drips water, and how reverse cycle heats the same way.
