How Much Does It Cost to Run Air Conditioning in Malaysia?
Hourly, monthly and yearly cooling costs at Malaysia's current electricity prices, by unit size and efficiency and city, in local currency and U.S. dollars.

Quick answer
At RM0.4893 per kWh (September–December 2026 rules), 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 RM0.34 an hour to run, or RM82 for a month at 8 hours a day. Over a year it comes to about RM754 in Kuala Lumpur (about $185), and from RM685 in Ipoh to RM788 in George Town (Penang). In U.S. terms the price is about 11.99¢/kWh, 35% less 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 Kuala Lumpur and the price at RM0.4893; change them for your home and your bill.
Yearly cost by city
This table is for one 1.5 hp (12,000 BTU, 3.5 kW) inverter split, which uses about 0.70 kWh of electricity for each hour it runs. Hours per year is our estimate of how long it runs at full power in each city's climate. Cost per year is those hours × 0.70 kWh × RM0.4893.
| City | Hours the AC runs per year | Cost per year, 1.5 hp inverter split | Same in U.S. dollars |
|---|---|---|---|
| George Town (Penang) | 2,300 | RM788 | $193 |
| Kuala Lumpur | 2,200 | RM754 | $185 |
| Johor Bahru | 2,100 | RM719 | $176 |
| Ipoh | 2,000 | RM685 | $168 |
Cooling hours are our estimate of full-load hours for each city's climate, for one unit. A home cooling several rooms uses more.
The price used here
What this table shows
- Price per kWh: what each kWh adds when air conditioning takes a home from 300 to 600 kWh a month, on TNB's domestic tariff (energy 27.03, capacity 4.55 and network 12.85 sen a kWh), after the Energy Efficiency Incentive rebate shrinks from 22.5 to 9.0 sen a kWh, under the September–December 2026 rules (no AFA, retail charge or service tax up to 800 kWh).
- 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 |
|---|---|---|---|---|
| Tenaga Nasional (TNB) | Peninsular Malaysia | RM0.4893 | 11.99¢ | RM0.34 |
Cost by unit size
In Malaysia, air conditioners are usually sold by horsepower: a 1.5 hp 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 RM0.4893 per kWh:
| Unit size (cooling output) | Typical use | Cost per hour of running | Cost per month (8 hours a day) | Cost per year in Kuala Lumpur (2,200 hours) |
|---|---|---|---|---|
| 1 hp · 2.5 kW (9,000 BTU) | bedroom | RM0.24 | RM59 | RM538 |
| 1.5 hp · 3.5 kW (12,000 BTU) | large bedroom or living room | RM0.34 | RM82 | RM754 |
| 2 hp · 5 kW (18,000 BTU) | large living room | RM0.49 | RM117 | RM1,076 |
| 2.5 hp · 7 kW (24,000 BTU) | open-plan living area | RM0.69 | RM164 | RM1,507 |
| Portable | one room, no installation | RM0.49 | RM117 | RM1,076 |
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 Kuala Lumpur (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 | RM1,256 | — |
| 4.0 | older or basic inverter unit | 0.88 kWh | RM942 | RM314 |
| 5.0 | typical new inverter split | 0.70 kWh | RM754 | RM502 |
| 6.0 | efficient model | 0.58 kWh | RM628 | RM628 |
| 7.0 | top models | 0.50 kWh | RM538 | RM718 |
What to know about electricity prices in Malaysia
Since July 2025, TNB bills households a generation charge, a capacity charge and a network charge for every kWh, plus a monthly fuel adjustment (AFA). Homes using under 1,000 kWh a month get an Energy Efficiency Incentive rebate, worked out from the home's total use: the more you use, the smaller the rebate on every kWh.
That's why air conditioning costs more per kWh than the headline rate: going from 300 to 600 kWh a month cuts the rebate from 22.5 to 9.0 sen on every kWh, so each kWh the AC adds costs about 49 sen, not 44.
Until December 31, 2026, homes using up to 800 kWh a month pay no AFA (+3.61 sen in October 2026), retail charge or service tax. From January 2027 that limit drops back to 600 kWh, so a home using more than that will pay more for the same cooling. Sabah and Sarawak have their own utilities and tariffs.
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.

Frequently asked questions
How much does it cost to run an air conditioner per hour in Malaysia?
About RM0.34 an hour in Kuala Lumpur for a typical 1.5 hp (12,000 BTU, 3.5 kW) inverter split, which uses about 0.70 kWh of electricity an hour, at RM0.4893 per kWh. A 1 hp (9,000 BTU) bedroom unit costs about RM0.24 an hour, an old non-inverter 1.5 hp unit about RM0.57, and a portable unit about RM0.49.
How much does air conditioning add to a monthly bill in Malaysia?
Running a 1.5 hp inverter split 8 hours a day for 30 days uses about 168 kWh, or about RM82. Over a year in Kuala Lumpur, at our estimate of 2,200 cooling hours, one unit costs about RM754 (about $185).
Is an inverter air conditioner worth it?
Where the AC runs as many hours as it does in Kuala Lumpur, usually yes. Replacing an old non-inverter 1.5 hp unit (efficiency about 3) with a typical inverter split (about 5.0) saves about RM502 a year at 2,200 hours.
How we calculated this
Electricity used (kWh) = cooling capacity (kW) ÷ seasonal efficiency × hours. Cost = kWh × price. Price: TNB domestic tariff from July 2025 (energy 27.03, capacity 4.55, network 12.85 sen/kWh up to 1,500 kWh; Energy Efficiency Incentive bands) and the September–December 2026 exemption up to 800 kWh; our calculation. U.S. figures use 1 MYR = $0.2450 (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.
