⚡ How Much Does Your AC Cost to Run per Month?
Calculate how much electricity your AC uses per day, month, and 3-month season — and how much that costs on your local tariff. Compare Inverter vs Non-Inverter, in USD, INR, AED, SAR, EUR, GBP or AUD.

Air Con Running Costs in Queensland
Queensland runs air conditioning longer than any other Australian state — Brisbane’s humidity, Cairns’ tropical wet season, and inland heat mean cooling from October through April. Typical 2026 usage rates sit around 28–32 cents per kWh in South East Queensland (the calculator above defaults to 30c). In SEQ your power comes via the Energex network through retailers like Origin, AGL, and Alinta; regional Queensland is served by Ergon Energy with regulated pricing. Enter the usage rate from your own bill above for an exact AUD estimate.
Queensland Electricity Prices at a Glance (2026)
| Area / Tariff | Network | Typical Rate |
|---|---|---|
| Brisbane, Gold Coast, Sunshine Coast (Tariff 11) | Energex | 28 – 32 c/kWh |
| Regional QLD (Tariff 11, regulated) | Ergon | 29 – 33 c/kWh |
| Economy / controlled load (Tariff 33) | Energex / Ergon | 19 – 24 c/kWh |
| Demand-tariff peak window (4–9pm) | Energex | varies — peak demand charge applies |
Queensland’s famous Tariff 33 (economy controlled load) can run pool pumps and hot water cheaply, but standard air conditioning sits on Tariff 11 — so your AC pays the full rate.
Tropical Cooling Is Different: Humidity Rules
From Brisbane northwards, your air conditioner’s job is as much drying as cooling. In Townsville or Cairns wet season (December–March), outdoor air can hit 32°C at 80% humidity — the moisture load is enormous:
- Inverter splits earn their keep in the tropics: long low-speed runs strip humidity continuously instead of the cold-then-clammy cycling of fixed-speed units. Compare both modes in the calculator above.
- Dry mode is a Queensland secret weapon on 28–30°C muggy days — comfort at roughly half the kWh of full cooling.
- Don’t oversize — an oversized unit in Brisbane cools fast but leaves moisture behind, feeding the mould that plagues Queensland cupboards and ceilings.
Cutting the Queensland Cooling Bill
- Rooftop solar rules here: Queensland has Australia’s highest solar uptake — with feed-in tariffs of only ~4–6c/kWh, running your air con hard from 10am–3pm on your own solar is essentially free cooling. Pre-cool the slab and rooms, then coast into the evening.
- Join a retailer peak-smart / demand-response program (Energex’s PeakSmart air con incentives paid households to install signal-ready units).
- Shade east and west walls — Queensland’s low-angle morning/afternoon sun loads walls and windows more than the midday sun southern states worry about.
- Service filters before the wet season — mould-clogged filters cost airflow, efficiency, and indoor air quality.
- Ceiling fans in every Queenslander room: 2c/hour each, letting you set the AC at 25°C instead of 22°C.
Frequently Asked Questions — Queensland
How much does air con cost per hour in Brisbane? A 2.5 kW bedroom split costs roughly 18–28c/hour; a 7 kW living-area split 50–75c/hour; ducted systems $1.30–$2.30/hour — get your exact numbers from the calculator above at your tariff.
What does running the air con all summer cost in Queensland? A typical SEQ family using a living-area split 8 hours daily spends roughly $130–$190/month at 30c/kWh across the November–February peak — solar households often cut that by more than half.
Is Ergon more expensive than Energex? Regional (Ergon) regulated rates are similar to SEQ retail offers, but SEQ customers can shop between competing retailers for discounts while most Ergon-area customers cannot.
