Once you have decided on the air conditioning system for your home you will probably be interested to know how much it will cost to run. Actual running costs depend on the size of the unit and how much time it is operating at full load and your local electricity cost. The examples below will give you an idea of the maximum cost per hour for heating and cooling. In the product information you have received there will be several numbers that will help you understand how much it will be to run the system for both heating and cooling. If the data sheet has Power Input figure in kW (not the heating or cooling capacity of the unit) you simply multiply this number by your local energy cost in kWh (kilowatt hours) to give you a running cost in cents. If the input power figure is not given you will need to divide the Cooling Capacity figure by the EER figure and then multiply this by your local energy cost. e.g. 1 Input power rating for a 6.0kW wall hung split system is 1.84kW.

Multiply this by your local electricity cost (varies quite bit within Australia so check your latest electricity bill.) say 25* cents per kilowatt hour. e.g.2 Running cost = 1.84 X 25 = 46 cents per hour For the same unit the Cooling Capacity is 6.0 divided by EER of 3.26 = 1.84 1.84 X 25* cents = 46 cents per hour. For heating use the heating capacity and the COP figures instead of cooling capacity and EER. e.g. 3 For this unit the Heating capacity is 7.0 and the COP is 3.41 7.0 divided by 3.41= 2.05 multiply this by your energy cost (25c*) and you get a heating mode running cost of 51.25 cents per hour. * Please note the 25 cents per kilowatt hour amount is used purely to show you how the calculation works. Actual rates vary considerably both above and below 25cents and you should consult your most recent electricity bill or your electricity supplier for your actual electricity tariff.Cool runnings – How much electricity does a portable air conditioning unit use?

It makes a nice change to have a summer in which keeping cool is the only problem! There’s certainly been a rush for fans in the shops this year, with portable air conditioner units becoming the ‘must have’ electrical item this summer, whether it’s to cool an office or home environment.  So how do they work? and more importantly how much do they cost to run? An air conditioner works in the same way as your fridge, cooling your room by passing warm air over a cold evaporator coil, and then blowing cooled air into your room.  This process also generates hot air that needs to be vented out of the building by an exhaust hose, usually placed through a window. Another often forgotten element of this cooling process is that it generates water and dries the air, that’s why portable air conditioning units have water tanks that need to be emptied. How do I keep my room cool and my air conditioning unit running efficiently? Carrying on the fridge theme… if you think of your room as a fridge, the last thing you’d do is leave the fridge door open, the same applies to the room you’re trying to cool.

Keep your space well sealed by closing doors and windows, this will ensure you get the best out of the air con unit. central air conditioner replacement partsClosing blinds and curtains will reduce the heat from sunshine through windows and doors. air conditioning outside unit partsGood levels of insulation will help keep rooms cooler in summer, as well as warmer in winter.  top rated air conditioners unitsHot summers may be a rare experience for the UK, but travel to Europe – France, Spain, or Italy and you’ll find plenty of external shutters preventing the suns heat entering the room. What do you look for when buy an air conditioner?  A thermostat is pretty crucial!  You don’t want to waste energy trying to get your room too cold, and a timer is good bet also. 

Like other electrical applicances, air conditioners have energy efficiency labels, graded from A to G for energy efficiency; go for the best you can afford and save long-term. Washable pre filters and odour eating carbon filters are useful features. How much do they cost to run? Just check the power consumption figures, then use Sust-it’s energy cost calculator to see what that will cost to run per hour.  Click here to see the potential air conditioner running costs.

How much does it cost to run your air conditioner? It doesn’t cost as much as you think. A recent Canstar Blue survey found that many Australian households cut down on using their air conditioner to save money on their electricity bills. Respondents estimated that 24% of their electricity bill comes from their air conditioner, so it’s no surprise that almost half (48%) said electricity efficiency is their number one deciding factor when choosing an air conditioner.

But how much will it really cost you to use your air conditioner? Spoiler: It’s less than you might think. You can look up the wattage of an air conditioner and calculate your annual appliance running costs on the Government of South Australia website but in the meantime, here’s our breakdown of the stats on electricity costs, whether you’re using your air con for heating or cooling. How much does it cost to run an air conditioner for heating? The average reverse cycle air conditioner costs around $0.33 – $0.40 per hour to run for heating purposes. An electric radiator heater costs about the same at $0.33 per hour, as does an electric panel heater at $0.40, but neither of these will heat as large an area. A gas heater costs more at $0.47 – $0.52 per hour. A ducted whole-house reverse cycle air conditioning system costs the most, at $1.48 – $1.94 per hour, so you’d want to live somewhere that really, really needed it. How much does it cost to run an air conditioner for cooling?

The average reverse cycle air conditioner costs around $0.11 – $0.75 per hour to run for cooling purposes, depending on the size of the room. A medium sized room of 36sqm would cost $0.38 – $0.54 per hour to run. A portable refrigeration device costs about the same at $0.36 – $0.46 per hour. The real winners on cost – but perhaps not on cooling ability – are ceiling fans and portable fans, at just $0.02 – $0.03 per hour. Portable evaporative devices come in at a close second, costing around $0.02 – $0.03 per hour for electricity, plus less than $0.02 per hour for the water used by the device to cool the air. A ducted whole-house reverse cycle air conditioning system is again the biggest money pit, at $2.26 – $2.67 per hour to run. That’s significantly more expensive than if you were using the system for heating, but if you want every inch of your house or office to be icy cool, well… What costs more to run than an air conditioner? Kitchen appliances are a silent killer.

Ovens cost $0.61 – $1.29 per hour to run. The stove costs $0.61 – $1.29 per hour per element being used. Gas stoves, ovens and grills cost slightly less than electric ones, at $0.48 per hour. Even the humble microwave costs $0.27 – $0.51. Cleaning appliances are more expensive to run than your air conditioner, with irons and vacuum cleaners both costing $0.41 – $0.82 per hour to run. Clothes dryers cost much more to run than your air conditioner, starting at $0.50 and costing anything up to $3.14 per hour to run. (Read more about this from Canstar Blue here.) Lighting your home is very expensive. While running a single bulb can cost as little as $0.01 per hour for an energy-efficient compact fluorescent light, few people run just one bulb at a time. It can cost anything from $0.24 – $1.68 per hour to run several of the bulbs in your home at once. If you’re trying to cut back, you could try the “one light per room” or “one light per person in the house” rule.

Swimming pools and spas cost a great deal in electricity because of the regular need to run the pool filter ($0.23 – $0.45 per hour) and chlorination equipment ($0.04 – $0.06). It’s even more expensive if you have a gas water heater ($3.00 – $12.75) or a solar water heater ($0.15 – $0.23). What costs less to run than an air conditioner? Small appliances like computers, printers and phones cost less than 1 cent per hour to run. Heating water for showers, baths and washing accounts for 25% of the energy used in an average home. It costs $0.05 – $0.14 to run each bath. Dishwashers cost $0.12 – $0.55 per hour to run, in terms of electricity. TVs cost anything from less than 1 cent per hour up to $0.14 per hour for the larger plasma and LED models. How can I reduce the cost of using my air con? We’ve established that air conditioners aren’t necessarily the Big Bad Wolf when it comes to your power bills. However, there is still the potential for your power bill to shock you if you’ve been running your air con a fair bit through a particularly sweltering summer.

Here are some easy tips to potentially minimise the effect air con can have on your power bill: The easiest way to reduce the impact of air conditioning on your electricity bill is to maintain a consistent temperature throughout the day. It might seem counter intuitive, but setting the temperature to warmer in summer, and colder in winter, can ensure the air conditioner isn’t working too hard and hiking up your energy consumption. Generally, the best temperatures to go by are 24°C in summer and about 19°C in winter. Setting it to these temperatures will ensure both you and your wallet will stay comfortable. It’s tempting to take advantage of both the cross breeze and your air conditioner at the same time, but this can wreak havoc on the effectiveness of your air conditioner. This in turn can drive up your power bill. To make the environment the most ideal for your air conditioner to thrive, close the curtains and doors, and turn off any lights not in use. This reduces heat absorption and makes it easier for your air conditioner to operate.

In winter, using these practices can allow you to trap in more heat, which can prove friendly for your power bill. Correct air conditioning maintenance It’s easy to forget this one. Ensuring your unit is properly maintained can help the air conditioner run better, and reduce your power bill. Ensure the filter is regularly cleaned or replaced – usually this means once a month. Also dust the vents and any exterior components. Similar to a car, keeping it well maintained could reduce the overall cost of running it. This can be a bit tricky if you’re renting, but if you have your own home, then you’re in luck. Adequate insulation of your home reduces how much work your air con needs to do to cool or heat an area. If you’re building new it’s easy to ensure your home is correctly insulated. Alternatively, if you’re buying an existing property, it can pay to make sure the insulation is adequate. Have you considered a portable air conditioner? Or maybe you could install an evaporative cooler if you’re in a dry area?
