Air conditioning running costs
Modern inverter systems move heat rather than making it — so they run efficiently. Here's how that works, and what your system reports.
What does air conditioning cost to run?
A modern inverter air conditioner costs roughly 10–30p an hour to cool a typical room, depending on its size and your electricity tariff. Because it modulates rather than running flat-out, real-world costs are modest — and the same system heats efficiently in winter too.
Efficiency & monitoring
DEMO3.5 kW of heat or cool moved
A modern inverter system moves roughly 3–4 kW of heat for every 1 kW of electricity it draws — it moves heat rather than burning energy to make it.
