What It Costs to Run Air Conditioning in Asia

Electricity prices, hourly and yearly cooling costs, and what an inverter unit saves, in Brunei, Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, Taiwan, Thailand and Vietnam.

Quick answer

A typical 1.5 hp (12,000 BTU, 3.5 kW) inverter air conditioner uses about 0.70 kWh of electricity an hour. At current prices that costs from about B$0.06 an hour in Brunei (6.26¢ a kWh in U.S. money) to ¥27 in Japan (24.62¢). Over a year, the tropical cities pay most because the AC rarely gets a day off: one unit costs about $366 a year in Metro Manila, against $54 in Seoul.

My stores are in a climate a lot like Manila's or Bangkok's: hot all year, humid, and with power that isn't cheap. In that kind of climate the air conditioner is the biggest line on the bill, and the type of unit matters as much as the price of a kWh. These pages put both into numbers, in each country's own currency.

Prices: the price of each kWh air conditioning adds to a household bill, from each country's regulated tariff (sources and method on the country pages). Malaysia is Peninsular Malaysia (TNB); Hong Kong is CLP Power's area; Japan is the Tokyo and Kansai utilities; China is shaded by Shanghai, with Beijing and Guangzhou as dots. Laos and Myanmar aren't covered yet. Cooling hours: our estimate for each city's climate, for one unit. U.S. dollars at ECB reference rates. Yokohama, Kyoto, Kobe, Johor Bahru and Shenzhen are in the table but not drawn, because they sit on top of Tokyo, Osaka, Singapore and Hong Kong at this scale. Outlines: Natural Earth.

Cost to run AC by country

What this table shows

Every cost is for one 1.5 hp wall-mounted inverter split, the usual size for a living room or large bedroom. 1.5 hp is a sales size, not the electricity it uses: it puts out about 12,000 BTU (3.5 kW) of cooling and uses only about 0.70 kWh of electricity for each hour it runs.

  • Price per kWh: what each extra kWh of air conditioning adds to a household bill, in local currency, including taxes. Each country page explains exactly how it's worked out (some countries charge more per kWh the more you use).
  • Cost per hour: one hour of the AC running at full power, so 0.70 kWh × the price.
  • Cost per year: the cost per hour × how many hours a year the AC runs in each city's climate (our estimate). A home with two or three units pays two or three times as much.

Sorted by price in U.S. cents. Unit efficiency: 5.0 (kW of cooling per kW of electricity over a season), our assumption for a typical new inverter split. Exchange rates: European Central Bank euro reference rates, October 21, 2026 (crossed through the euro); New Taiwan dollar at market rate October 21, 2026; Vietnamese dong at the State Bank of Vietnam central rate, October 6, 2026; Cambodian riel at the National Bank of Cambodia official rate, October 21, 2026; Brunei dollar at par with the Singapore dollar.

Inverter or not: the biggest choice

In a climate where the AC runs 2,000 hours or more a year, an old non-inverter or window unit uses roughly two-thirds more electricity than a typical new inverter split for the same cooling. In Metro Manila that's about ₱15,463 a year for one 1.5 hp unit. In Kuala Lumpur it's about RM502. Look for the energy label rating your country uses (stars or ticks) and the word "inverter".

Japan is the exception to the rule: its price per kWh is among the highest here, but the cooling season is short, so a unit in Tokyo costs far less over a year than one in Bangkok or Singapore. There, the heating performance of a reverse-cycle unit matters as much as its cooling.

Not covered yet: Laos and Myanmar. Laos changed its household tariff in May 2026, but we couldn't find the published rate table; we'll add both when we can source a current price.

Frequently asked questions

Where in Asia is air conditioning most expensive to run?

Per kWh, Japan has the highest price of the 13 countries here (about 24.62¢ in U.S. money). Over a year, the hot, humid cities where the AC runs most of the year cost the most: one 1.5 hp unit costs about $366 a year in Metro Manila, against about $54 in Seoul.

How much does a 1.5 hp aircon cost to run per hour?

A typical 1.5 hp (12,000 BTU) inverter unit uses about 0.70 kWh an hour, so it costs about ¥27 in Japan, S$0.22 in Singapore, ₱10.54 in the Philippines, HK$1.19 in Hong Kong, ₩180 in South Korea, ៛511 in Cambodia, ₫2,533 in Vietnam, ฿3.24 in Thailand, RM0.34 in Malaysia, NT$2.66 in Taiwan, CN¥0.47 in China, Rp1,011 in Indonesia, B$0.06 in Brunei.

Is an inverter air conditioner worth it in a tropical climate?

Usually, yes. Where the AC runs 2,000 hours or more a year, replacing an old non-inverter unit (efficiency about 3) with a typical inverter split (about 5.0) cuts its electricity use by about 40%. Each country page shows the saving in local currency.
