Many people assume air conditioning is expensive to operate, but modern systems are far more efficient than older models.
Typical running costs depend on:
- system size
- efficiency rating
- electricity prices
- usage patterns
Typical Running Cost Example
A 3.5kW system may use roughly:
0.8–1.2 kWh per hour
At typical UK electricity rates this may cost roughly:
£0.20 – £0.35 per hour
Ways to Reduce Running Costs
You can improve efficiency by:
- keeping filters clean
- maintaining the system annually
- using programmable settings
- improving insulation
