Air Conditioning

Shade the glass, move air across your skin, and time your ventilation. What actually cools a room without an air conditioner, and where the limits are.

Reverse cycle is usually the cheapest of the three to run, and the reason is physics. Here is how heat pumps, gas and electric heaters compare on running cost, comfort and who is licensed to install them.

Ask any installer which split system is best and you will usually get a shrug and a question back: best for what, and best in whose hands? The honest answer…

So the aircon is running, the fan is humming, air is coming out of the vents, and the room still will not cool down. Before you start pricing up a…

Most aircon faults are just a machine left to choke on dust. Here is the simple monthly and seasonal maintenance routine, plus the jobs you should never touch yourself.

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.

An air conditioner does not make cold air, it moves heat out of your house. How it works, the system types, who is legally allowed to install what, sizing, running costs and maintenance.
