What an aircon really adds to your electricity bill

In a Philippine home, the aircon is often the biggest single electricity cost. A bedroom unit running through the night can add thousands of pesos a month, and the number surprises many first-time owners.

This calculator turns the horsepower, the hours and your rate into a monthly peso cost, then compares the same unit as an inverter or a non-inverter. If you run it for long hours, the savings of an inverter can cover the higher price within a few years.

How the aircon cost estimate works

Running power equals the horsepower times the watts per HP, adjusted for how much of the time the compressor actually runs.
Inverter models adjust the compressor speed, so the calculator reduces the energy by the saving you enter.
Monthly energy is the running power times the hours per day times the days, and the cost is that energy times your rate.
Payback is the extra price of the inverter model divided by the monthly difference.

Tips to save more

Set the thermostat around 24 to 26 degrees instead of the lowest setting.
Clean the filter every month so the unit does not work harder.
Use a timer so the unit shuts off after you fall asleep.
Check the energy rating when you compare models.

Frequently asked questions

How much electricity does a 1 HP aircon use?

A 1 HP window or split type often draws around 700 to 900 watts while the compressor runs, but real use depends on the model, the room and the temperature setting. Check the unit label for your model.

Is an inverter aircon really cheaper to run?

Inverter models usually use less energy because the compressor does not switch fully on and off. The saving depends on how many hours you run it, so heavy users benefit most.

How do I lower my aircon bill?

Set the temperature around 24 to 26 degrees, close doors and windows, clean the filter, use a timer and a fan to spread cool air, and keep direct sunlight out.

What rate per kWh should I enter?

Divide your total bill by the kWh on it, or read the generation and distribution charges. It changes monthly.

Does this include my other appliances?

No. For the whole house, use the electricity bill calculator and add the aircon as an appliance.
