Everyone asks about the sticker price. Few people ask the more important question. What does an air conditioner actually cost to run, month after month? That’s where the real money is. This guide is about LG air conditioner running costs – the power it uses day to day. We’re not covering the upfront install price here. For that, see our guide on aircon installation cost on the Gold Coast in 2026. Let’s break down what you’ll really pay to stay warm, with DEEPCHILL – Air conditioning Gold Coast.

What drives your running cost
Four things decide what your air conditioner costs to run.
The first is efficiency. A more efficient unit turns more of your power into heat. The second is size. A unit that’s too small runs flat out and burns power. One that’s sized right reaches temperature, then eases off.
The third is usage. Heating an empty house all day is pure waste. The fourth is control. Good scheduling means you only heat when you need it. Get these four right, and your costs drop fast.
How LG keeps the power draw down
LG builds its split systems around a Dual Inverter compressor. This is the heart of LG energy efficiency.
A basic air conditioner runs at one speed. It blasts on, then shuts off, then blasts on again. That start-stop cycle wastes power. An inverter works differently. It ramps up to warm the room quickly. Then it slows down to hold the temperature. It sips power instead of gulping it.
This is why LG inverter running cost stays low over a full day. The compressor rarely runs at full tilt for long.
LG also uses R32 refrigerant. R32 moves heat more efficiently than older refrigerants. It also has a lower environmental impact. The result is more warmth for each unit of electricity you buy.
So, are LG air conditioners cheap to run?
In short, yes – especially next to the alternatives. Here’s how the reverse cycle running cost compares. These are Australian estimates from Home Upkeep’s 2026 heater running cost guide, and your tariff will vary.
A reverse cycle split system costs roughly $0.20 to $0.36 per hour to heat a normal room. A plug-in electric heater runs closer to $0.50 to $0.79 per hour. Gas heaters land anywhere from $0.32 to $0.72 per hour, and gas prices keep climbing.
Why the big gap? It comes down to physics. A reverse cycle unit is a heat pump. It moves heat rather than making it from scratch. For every unit of power it draws, it delivers about three to four units of warmth. A plug-in heater gives you just one. Over a full winter, that difference is huge.

Only heat when you’re actually home
Even the most efficient unit wastes money if it runs all day for no one. This is where LG’s ThinQ app earns its keep.
With ThinQ scheduling, you set the heating around your day. Warm the living room before you wake up. Switch it off after everyone leaves. Warm it again just before you get home. You heat the rooms you use, when you use them – and nothing else.
You can also check your energy use in the app. That makes it easy to spot waste and trim it back.
Keep it efficient with servicing
Running cost isn’t only about the unit. It’s about how well you look after it.
A clogged filter forces the system to work harder. A unit that hasn’t been serviced slowly loses efficiency. Both quietly push your power bill up. A simple clean and a regular service keep it running at its best. See our guide on air conditioning maintenance to keep costs low year-round.
The payback maths
Here’s where it all comes together. An efficient LG unit costs less to run every single day. Over a few winters, those savings add up to real money.
Now add the current DEEPCHILL – Air conditioning Gold Coast sale price. The 2.5kW model (AS09SOS) starts from $556.50 + GST. The 7.2kW model (AS24S2S) is $1,102.50 + GST. Both include WiFi control. You buy the unit once, at a sale price. Then it saves you money on power for years.
That’s why the right air conditioner doesn’t just cost money. Over time, it pays for itself.
