Air Conditioning - How much to run?
Hi all -
Does anyone know how much it costs (approximately) to keep adomestic air-conditioning system running for say, 1 hour? We're in the middle of a heatwave here in Adelaide - up to yesterday we had 3 consecutive days over 40 deg C and today its 38. We've had the air-con on a fair few hours over the last few days and just now I've looked in the meter cupboard and the wheel was going round like the clappers! I'm now dreading the next electric bill!
It's a 3 bedroom house. Would anyone have a rough idea?

Depends on the size of it and whether it is a normal stop start machine or inverter. Look for the input current on the label which should be on the box outdoors.

Re: Air Conditioning - How much to run?
Write down the current meter reading, then take it again in an hours time. You will now know how many units you are using per hour. Find an old bill and look up how much you are charged per unit.
Your cooling costs are going to depend on how well you home is insulated, the age/condition/efficiency of the AC unit, how much your energy supplier charges, amongst many many other factors.
A simple bit of math will put your mind at rest (or send you to an early grave ).
Second meter reading - first meter reading * cost per unit

Re: Air Conditioning - How much to run?
It's a bit warm isn't it?
We've had ours on since last week non stop - I'm dreading my bill too, but it shouldn't be too bad as I pay $50 a fortnight, so when the bill comes I only have to make up the difference.
I wouldn't worry too much, the temps should be down to the high 20's from Sunday. It's very unusual to get more than one or two days of 40+ in a row.

Use the workings on your bill and just insert the new readings

I've noticed Brissy has been having around 27c for quite some days now
On Boxing Day it reached 44.3 here in Perth
You would think after 36 years I would be used to it
Going 'home' to Adelaide in 3 weeks to watch some of the Tour Down Under.
I remember a few years ago when I watched the fifth stage...Willunga/Willunga...the start/finish line was outside my cottage
It was 45c and the bottoms of my feet were burning and then I found myself stuck...my thongs had melted on the bitumen
