Quick answer
At ₱15.06 per kWh (October 2026), a typical 1.5 hp (12,000 BTU, 3.5 kW) inverter air conditioner, which uses about 0.70 kWh of electricity an hour, costs about ₱10.54 an hour to run, or ₱2,530 for a month at 8 hours a day. Over a year it comes to about ₱23,195 in Metro Manila (about $366). In U.S. terms the price is about 23.79¢/kWh, 30% more than the U.S. average.

Efficiency = kW of cooling per kW of electricity over a season (our assumption for a typical new inverter split is 5.0; an old non-inverter or window unit is closer to 3). Hours start at our estimate for Metro Manila and the price at ₱15.06; change them for your home and your bill.
The price used here
What this table shows
- Price per kWh: Meralco's overall residential rate for October 2026 bills, for a typical household using 200 kWh a month, including generation, transmission, distribution, taxes and other charges..
- Cost per hour: one 1.5 hp (12,000 BTU, 3.5 kW) inverter split running for an hour at full power (0.70 kWh × the price).
| Utility | Area covered | Price per kWh | Same in U.S. cents | Cost per hour of ACone 1.5 hp inverter split |
|---|---|---|---|---|
| Meralco | Metro Manila and nearby provinces (Bulacan, Cavite, Laguna, Rizal and parts of Batangas, Pampanga and Quezon) | ₱15.06 | 23.79¢ | ₱10.54 |
Cost by unit size
In the Philippines, air conditioners are usually sold by horsepower: a 1.5 hp split or window unit is about 12,000 BTU (3.5 kW) of cooling. The size is how much cooling the unit puts out, not the electricity it uses.
All at a seasonal efficiency of 5.0 (our assumption for a typical new inverter split) and ₱15.06 per kWh:
| Unit size (cooling output) | Typical use | Cost per hour of running | Cost per month (8 hours a day) | Cost per year in Metro Manila (2,200 hours) |
|---|---|---|---|---|
| 1 hp · 2.5 kW (9,000 BTU) | bedroom | ₱7.53 | ₱1,807 | ₱16,568 |
| 1.5 hp · 3.5 kW (12,000 BTU) | large bedroom or living room | ₱10.54 | ₱2,530 | ₱23,195 |
| 2 hp · 5 kW (18,000 BTU) | large living room | ₱15.06 | ₱3,615 | ₱33,135 |
| 2.5 hp · 7 kW (24,000 BTU) | open-plan living area | ₱21.09 | ₱5,061 | ₱46,389 |
| Portable | one room, no installation | ₱15.06 | ₱3,615 | ₱33,135 |
What a more efficient unit saves
Seasonal efficiency is how much cooling a unit delivers for each kW of electricity over a whole season. The higher it is, the less electricity it needs for the same cooling. Yearly cost of one 1.5 hp (3.5 kW) unit in Metro Manila (2,200 hours a year):
| Seasonal efficiency | What it's like | Electricity per hour | Cost per year | Saved per year vs an old 3.0 unit |
|---|---|---|---|---|
| 3.0 | old non-inverter or window unit | 1.17 kWh | ₱38,658 | — |
| 4.0 | older or basic inverter unit | 0.88 kWh | ₱28,993 | ₱9,664 |
| 5.0 | typical new inverter split | 0.70 kWh | ₱23,195 | ₱15,463 |
| 6.0 | efficient model | 0.58 kWh | ₱19,329 | ₱19,329 |
| 7.0 | top models | 0.50 kWh | ₱16,568 | ₱22,090 |
What to know about electricity prices in the Philippines
Meralco's rate changes every month, mostly because of the generation charge, which follows fuel costs and the wholesale market. October 2026's rate rose by about ₱0.32 a kWh. Your bill shows each month's rate.
The rate here is for a typical household. Homes that use more pay a similar price per kWh, while very small users get a lifeline discount. Outside Meralco's franchise area, other distribution utilities and cooperatives (in Cebu, Davao and elsewhere) set their own rates.
Window-type and older non-inverter units are still common in the Philippines. Replacing one with an inverter split is often the single biggest saving available, because the unit runs for so many hours.
Cutting the cost
- Set 25–26°C rather than 20–22°C, and run a ceiling or stand fan with it.
- Close curtains on sunny windows, and keep doors closed so you only cool the room you're in.
- Clean the indoor unit's filters every two to four weeks; humid, dusty air clogs them fast.
- Have the unit serviced (coil and drain cleaning) about once a year.
- When you replace a unit, choose an inverter model with a high energy label rating.

A 1 hp (9,000 BTU) bedroom unit costs about ₱7.53 an hour, an old non-inverter 1.5 hp unit about ₱17.57, and a portable unit about ₱15.06.
How much does air conditioning add to a monthly bill in the Philippines?
Running a 1.5 hp inverter split 8 hours a day for 30 days uses about 168 kWh, or about ₱2,530. Over a year in Metro Manila, at our estimate of 2,200 cooling hours, one unit costs about ₱23,195 (about $366).
Is an inverter air conditioner worth it?
Where the AC runs as many hours as it does in Metro Manila, usually yes. Replacing an old non-inverter 1.5 hp unit (efficiency about 3) with a typical inverter split (about 5.0) saves about ₱15,463 a year at 2,200 hours.
How we calculated this
Electricity used (kWh) = cooling capacity (kW) ÷ seasonal efficiency × hours. Cost = kWh × price. Price: Meralco, overall rate for a typical household in October 2026 (₱15.0615 per kWh, up ₱0.3191 from September). U.S. figures use 1 PHP = $0.0158 (October 21, 2026, European Central Bank). Cooling hours are our estimate for each city. To check your own price, divide the energy part of your bill by the kWh used.
