How we calculate AC electricity cost
Formula: Hourly cost = Power consumption (kW) × Hours of use × TNB tariff (RM/kWh)
For an inverter 1.5 HP unit running at average 50% capacity:
Hourly cost = 0.55 kW × 1 hour × RM 0.425/kWh = RM 0.23/hour
For non-inverter 1.5 HP (always full power when running):
Hourly cost = 1.1 kW × 1 hour × RM 0.425/kWh = RM 0.47/hour
Power consumption by HP and type
| HP | BTU | Inverter (avg) | Non-Inverter (full) |
|---|---|---|---|
| 1.0 HP | 9,000 | ~0.45 kW | ~0.85 kW |
| 1.5 HP | 12,000 | ~0.55 kW | ~1.10 kW |
| 2.0 HP | 18,000 | ~0.80 kW | ~1.55 kW |
| 2.5 HP | 24,000 | ~1.00 kW | ~2.00 kW |
| 3.0 HP | 30,000 | ~1.30 kW | ~2.50 kW |
Per day cost (8 hours use)
| HP & Type | Per Hour | Per Day (8h) | Per Month (30d) |
|---|---|---|---|
| 1.0 HP inverter | RM 0.20 | RM 1.60 | RM 48 |
| 1.5 HP inverter | RM 0.27 | RM 2.16 | RM 65 |
| 2.0 HP inverter | RM 0.36 | RM 2.88 | RM 86 |
| 2.5 HP inverter | RM 0.45 | RM 3.60 | RM 108 |
| 3.0 HP inverter | RM 0.58 | RM 4.64 | RM 139 |
| 1.0 HP non-inverter | RM 0.36 | RM 2.88 | RM 86 |
| 1.5 HP non-inverter | RM 0.47 | RM 3.76 | RM 113 |
| 2.0 HP non-inverter | RM 0.66 | RM 5.28 | RM 158 |

| 3.0 HP non-inverter | RM 1.06 | RM 8.48 | RM 254 |
TNB tariff blocks (residential, 2026)
| Block | Rate (RM/kWh) |
|---|---|
| First 200 kWh/month | RM 0.425 |
| 201-300 kWh/month | RM 0.571 |
| 301-600 kWh/month | RM 0.634 |
| 601-900 kWh/month | RM 0.686 |
| Above 900 kWh/month | RM 0.766 |

Inverter vs non-inverter electricity cost comparison
For the same 1.5 HP unit running 8 hours/day, 30 days/month:
- Inverter: ~RM 65/month (assuming 50% average load with cycling)
- Non-inverter: ~RM 113/month (always full power when on)
- Savings: ~RM 48/month = ~RM 576/year
Over a typical 10-year lifespan, inverter saves RM 5,760 in electricity. The unit cost difference is usually RM 500-1,500. Inverter is worth it for ACs used 4+ hours daily.
How to reduce AC electricity cost
- Set temperature to 25-26°C (not lower) — every 1°C lower adds 5-7% to consumption.
- Use fan + AC combo — fan lets you set AC 1-2°C higher with same comfort.
- Clean filters every 2 weeks — dirty filters add 10-15% consumption.
- Close doors and windows — open doors let cool air escape.
- Use timer/sleep mode — drops 2-3°C overnight automatically.
- Service every 6 months — chemical wash keeps efficiency high.
- Use blackout curtains — west-facing rooms can be 3-5°C hotter.
- Don't run AC in empty rooms — basic but many forget.
How many hours should I run my AC?
Cost-effective usage:
- Bedroom: 6-8 hours overnight with timer/sleep mode
- Living room: 4-6 hours evening with timer
- Study room: 2-4 hours as needed
- 24/7 cooling (server, shop): budget for it, choose inverter
Common AC electricity myths
Myth 1: "Turning AC on and off uses more electricity than leaving it on"
False. Turning off when leaving saves electricity. The startup surge is small compared to continuous running. Use a timer or smart plug to automate.
Myth 2: "Larger AC cools faster so uses less electricity"
False. Larger AC short-cycles and uses more power. Match AC size to room size (1 HP for 100-120 sqft, etc.).
Myth 3: "Setting temperature very low cools the room faster"
False. The AC outputs the same temperature regardless of setpoint. Set 25-26°C for comfort and savings.
Myth 4: "Sleep mode saves electricity"
True. Sleep mode gradually increases the setpoint by 1-2°C over 2-4 hours, saving 5-10% on overnight use.

FAQ — 1 hour AC electricity cost in Malaysia
How much does 1 hour of AC cost in Malaysia?
RM 0.20-0.45 for 1.0-1.5 HP inverter, RM 0.40-0.55 for non-inverter. Per hour cost depends on HP, inverter vs non-inverter, and TNB tariff block.
How much does 8 hours of AC cost?
RM 1.60-3.60 for 1.0-2.0 HP inverter (8 hours). RM 2.88-5.28 for non-inverter of the same sizes.
How much does 24 hours of AC cost?
For 1.5 HP inverter running 24 hours: ~RM 6.50/day or ~RM 195/month. Non-inverter 1.5 HP: ~RM 11.30/day or ~RM 339/month.
Do inverter airconds really save electricity?
Yes. Inverter compressors ramp up/down based on demand instead of full on/off. Typical savings: 30-40% on electricity. Over 10 years, savings easily cover the higher upfront cost.
What is the cheapest way to run an aircond in Malaysia?
Use an inverter unit at 25-26°C with a ceiling fan. Service every 6 months. Close all doors and windows. Use timer for sleep mode. This combination keeps costs at RM 50-70/month for typical home use.
Does AC electricity cost increase at higher TNB tariff blocks?
Yes. TNB uses a tiered tariff: first 200 kWh at RM 0.425, then RM 0.571, RM 0.634, RM 0.686, RM 0.766 for higher blocks. Heavy AC users pay more per kWh.
How much does it cost to run AC all night in Malaysia?
8 hours of 1.5 HP inverter: ~RM 2.16/night or RM 65/month. Non-inverter: ~RM 3.76/night or RM 113/month. Using sleep mode reduces the cost by 10-15%.
What is the best temperature for AC in Malaysia?
25-26°C is the sweet spot. Comfortable for most people, lowest energy use. The Ministry of Health and MOSTI recommend 24-26°C for energy efficiency and comfort.
Can I use solar to power my AC?
Yes, but the solar system needs to be sized appropriately. A 1.5 HP AC uses ~4-5 kWh/day. You need at least a 2-3 kWp solar system to cover one AC plus other loads. Payback period is typically 4-6 years.
Does ceiling fan with AC really save electricity?
Yes. A ceiling fan uses 30-50W. Running both at 26°C feels like 24°C. You can set AC 1-2°C higher with the fan, saving 5-10% on AC electricity. Net effect: cooling costs less overall.
