Disclaimer
The calculators multiply the figures you enter using standard rules of thumb. They are not a substitute for a professional cooling load calculation or an electrician's assessment of your installation.
Sizing guidance
Air conditioner sizing here uses widely applied approximations. It cannot account for wall construction, insulation, glazing, orientation or local climate, all of which materially change the answer. Have an installer confirm before purchase, and treat a suggestion far from this estimate as worth questioning in either direction.
Running cost estimates
Actual consumption varies with ambient temperature, how the appliance is used, how full it is, and how it ages. Tariffs are frequently slabbed, so additional units may cost more than your average rate. Treat results as a basis for comparison rather than a prediction of your bill.
Electrical safety
Nothing here is electrical installation advice. Wiring, earthing, circuit ratings and stabiliser selection should be handled by a qualified electrician.
