It’s not that hot now, but just you wait. Parts of your body will stick to other parts of your body, and it will be horrible. Lucky for you, you’ve got air conditioning. Unlucky for you, it’s a real punisher on the power bill.Here are a few tips for maximising your cool without crippling your bank account.
Don’t Be Greedy
You’ve been sweating your face off outside, and nothing feels better than coming into a nice cold room. Your impulse will be to set your A/C to 18C and let it get nice and nippy. Don’t. Keep it set to 26. You don’t need to be cold, you just need to be comfortable. For every degree below 26C, you are increasing your energy usage by approximately 8 per cent. No bueno. You don’t need to be indoors in a jumper. Keep it at 26 or higher, and rock a t-shirt and shorts. If you have a window unit with low, medium and high settings as your only options, keep it as low as you can handle.
Divide and Conquer
It’s better to use your A/C minimally and have one cool room than to have your A/C maxed out and have your whole apartment only marginally less blistering. If you don’t have a door that you can close between rooms, improvise! Hang a thick blanket in between rooms to create a nice cool-box that doesn’t stress your A/C. (I recommend using picture-frame hangers, and then threading a few safety pins into the blanket so it’s easy to put up and take down.)
Fan-tasise
Ceiling fans use waaaay less power than an A/C unit, consuming about the same amount of energy as a 100W light bulb, which isn’t too bad, comparatively. Make sure the fan is going in the correct direction so that is pushing air downward toward you (the higher edge of the fan-blade should be the leading edge in its rotation). Ceiling fans don’t actually make the room cooler, but they make you feel cooler when they’re blowing on you (think wind-chill). As with an A/C unit, if you’re not in that room, turn your fan off.
Keep It Clean
Your A/C unit has a filter. It’s thin, light, easily removable, and if you’ve never seen it then it’s probably pretty disgusting right now. Pull it out, stick it in the shower, and give it a good once-over with a sponge. Let it dry then put it back in — and be thankful you aren’t breathing that crap anymore. This will increase the unit’s output and lower the temp. The other half of this is keeping the coil clean. If you’re on the ground floor, then it’s pretty easy: just use a garden hose to blast some water into the unit through the grates at the top and the sides. If you’re on an upper floor of an apartment building, you’re going to have to get creative. Try using a portable, pumpable paint-sprayer (but use water, not paint… duh).
Slickaslicka Slim Shady
This one’s a twofer. Keeping your air-conditioning unit in the shade can make it up to 10 per cent more efficient. That’s pretty major. If you have means to build a shade for it (that’s not too close so there’s no vent blockage), by all means, do it.
The other half of this is shading your apartment. When it’s hot and sunny, lower your blinds, yes, obviously, but if you really want to see a difference get yourself some honeycomb blinds. They are fantastic insulators. They will help keep the cooled air in in the summer, and they’re great for the winter when you want to keep the cold air out (and they can darken the hell out of a room for a more cinematic movie viewing experience). They will reduce your bill and start paying for themselves very quickly.

Tuesday, August 2, 2011 at 9:28 AMWe use 100% green power, and I couldn’t care less how much it costs to have the A/C keeping the temp at 20C indoors. In fact our power bill last summer was not really that much higher than when we weren’t using the A/C, so I guess our unit is pretty efficient.
That said, keeping the filter clean will make it more effective, so is absolutely a good idea.

Tuesday, August 2, 2011 at 10:09 AMYou do realise that ‘Green Power’ is just more expensive ‘regular power’ don’t you? It’s not some Newfangled alternative! #]

Tuesday, August 2, 2011 at 1:11 PMThat’s not entirely true.
While it is true that the energy you consume is likely coming from non-green sources, that is not the point of purchasing green energy.
What you are paying for is the generation of renewable, clean energy that is added to the total energy output of the grid, you may not use it directly but you have commissioned its generation.
That being said, the more users that subscribe to green energy, the more likely it is that you will actually receive that power to your home.

Tuesday, August 2, 2011 at 1:55 PMI understand what you’re saying but!.. What exactly are these renewable power sources,.. Wind farms? I can’t help the feeling that punters are being shim shammed on this one!! #]

Tuesday, August 2, 2011 at 2:40 PMI’m waiting to see an ad recruiting people to work on wind farms. My wife says I’d be incredibly productive.

Wednesday, August 3, 2011 at 4:06 PMNope. Actually, it means that our energy provider purchases the same amount of energy that we use from renewable sources to be fed into the grid – 100%.
And depending on your provider it isn’t necessarily more expensive than dirty power, though clearly not as cheap as having your own installation and paying nothing.

Tuesday, August 2, 2011 at 3:36 PMWhat about reverse cycle in winter? Still 26? Or the cooler the better?

Tuesday, August 2, 2011 at 4:23 PMI believe from info I got from my aircon installer ten years ago, that 24 degrees C is more economical.

Tuesday, August 2, 2011 at 4:24 PMOh, and if you have reversible ceiling fans then use them also!!
It's Hot in Adelaide
Thursday, January 26, 2012 at 10:00 AMWho lives in an apartment? I don’t know anyone who does. I rent and I have a house. In fact I’ve always rented houses.
We don’t have aircon. We use fans (the pedestal type) wet towels and have alfoiled all our windows to keep the sun out.

Thursday, January 26, 2012 at 1:39 PMThat was a bit harsh wasn’t it? Even if the comment before was really ignorant/naive.
As to the comment before, I’m quite curious… Did you actually go out and by alfoil to cover the windows, or am I missing something?

Thursday, January 26, 2012 at 10:58 AMWho rents a house? I think your stupid if you do. I’d much rather pay off my own house weekly than pay off somebody else’s mortgage, and live in a house. With aircon!

Friday, January 27, 2012 at 2:12 PM” Who lives in an apartment? I don’t know anyone who does. ”
So, YOU don’t know anyone, so that means no one does?
Have you never seen all the unit blocks around everywhere?
Do you think they’re all empty?
Seriously.. WTF?

Thursday, January 26, 2012 at 12:21 PMYeah this all makes sense. I mean really, people that sit inside on hot summer days with blankets because it is ice cold inside are really just deluded and frankly, stupid. And irresponsible. Anyway! Good times.

Thursday, January 26, 2012 at 3:12 PMCheap ass cooling solution:
1. Get a huge bucket and bendy hose from hardware store: $25
2. Buy lots of ice: $8
3. Wrap hose around the back side of a fan. Put one end of the hose in the bucket and one end out a window (or in a sink). Put the ice in the bucket. Put lots of salt on the ice (helps it melt quicker). Put some water in there too. Siphon the water through the hose so it gets a bit of a flow going.
4. turn fan on. BAM, cool room in about 15 mins.

Thursday, January 26, 2012 at 10:27 PMI would like to see more solar panels in Australia than air-conditioners.
And less architects & developers who take the words “greenhouse effect” for inspiration to design houses & offices that are built like greenhouses to absorb & trap heat.

Friday, January 27, 2012 at 8:31 AMWe have a large bush outside our lounge room window with a sprinkler system.
Turn on the sprinklers with the windows open and fans going? Instant evaporative cooler hahaha.

Monday, January 30, 2012 at 11:39 AMMake sure your windows and curtains/blinds are closed to reduce the incoming heat. Put on the AC and turn on the fan in front of it so that it pushes the cold air in the direction you want. Our AC is in our lounge room on a side wall so it doesnt push the cold air in the direction when we’re sitting on the sofa, so we stick our pedastal fan in front of the AC and point it in our direction and away we go with cold air!
