What does air conditioning cost to run?
Less than most people expect. A modern inverter unit is an air-to-air heat pump: it moves heat rather than making it, so cooling a room is usually pennies an hour. Try the numbers for yourself.
How the calculation works
A heat pump moves heat rather than generating it, so it delivers several units of cooling for each unit of electricity.
Heating depends on the model
Some systems also heat a room. Ask the installer to confirm the model's heating performance. This calculation is for cooling.
Your figure varies
Real cost depends on the unit, your tariff, insulation and how hard you run it. This is a guide, not a quote.
Figures are indicative, based on a seasonal efficiency typical of a modern A++ inverter unit. They assume the unit runs at its rated output for the hours you pick, which tends to overstate a real inverter that modulates down. CoolMatch is an introduction service and does not offer finance.
