Old room air conditioner: annual energy use (kWh per year)

Enter how much energy your old one uses a year.

Look for the yellow EnergyGuide label on the air conditioner: it lists the estimated yearly electricity use in kWh. If it is gone, use the rated power on the nameplate or a plug-in energy meter over a day of cooling, and multiply by the number of cooling days a year.

What this calculator does not tell you

It counts electricity only. Purchase price, repair costs, delivery, and whether your current room air conditioner still works well are separate parts of the decision.
The ENERGY STAR figure for a new model is a standardized value. Your own use will differ with how the appliance is used and where it stands.
Your old figure may be a guess. If you can, measure it.
