I have a simple install for 7000btu spilt systems, back to back on brick wall, ground level. Not getting hard wired to mains.
Been quoted $500 each Aircon, this seems a little steep, this is more than what I paid for the units.
That is an extremely cheap price.
I install splits all the time and i don't know how he is making money off the install
$500 would be the minimum I'd charge without the sparkies connection to the power supply, usually about $150. At 35-45 bucks an hr, roughly 4-5 hrs is $145-175. Then you have the copper, insulation, trunking, screws, vac pump oil, fuel, phone, etc ontop you would not make any money on $500 as TAB_DR has also said.

That is spot on. You need a Licensed Electrician to run seperate 16 amp power circuits to each unit. That way each unit is protected with it's own circuit breaker and run in 2.5mm sq conductors which will easily handle the full 16 amps without any voltage drop over a long run back to the consumer board. Many people think it's a simple case to install these units, just plug it in to a 10 amp GPO and all will be fine. The truth is not everything will be fine. Modern A/C units have electronic controls and monitoring systems, voltage and amperage requirements play an integral part of the efficiency of how the unit will run. In summer when peak demand for power is required, your home can be forced to a reduced voltage, this altermately means the motors in the units have to work harder and if they work harder they also have heat issues. This in turn carries down the line they get their juice from (the socket outlet, and cable that feeds it) If that particular cable feed also feeds other outlets with appliances plugged in on it, it will become overloaded. Patential fire hazard been the result. This is why a seperate line is generally put in for dedicated use of the A/C unit only.
So - play it safe, call a qualified Electrician and have peace of mind as well.
I have a quote for a solar panel system(3kw) with the comment that the Powerboard outside is old but doable.
not sure what that means........... but if I wanted a powerful split aircon ( maybe 6kw or7 kw,,,,,,,is that powerful?) would that then cause a problem in any way ?
The 6-7 kW referred to above, for the AC would be cooling/heating output. Current draw would only be around 10 amps for a single phase unit that size. Equivalent to 2-2.5HP in the old measure.
If referring to 6-7 HP, then that is for a large system that does a whole house. May then need 3 phase.

$500ea for back to back installation & with power ready to go has heaps of profit and more so for more that 1 unit.
Don't get discouraged by some of the responses, some installers want to make $1000/day and some are happy with less.
Tell me about it, I mean there is bugger all cost in materials for the tradie, I am almost keen to do it myself with the help of a mate that has worked as a laborer helping install a/c for a long time....
Just stuffs me the price some ppl have the nerve to charge for a few hours work...
Some might say you have a nerve for not wanting to pay a skilled tradesman what he's worth.
Do you say the same thing about what your Accountant and Solicitor charge?
I fail to see the difference myself, then again if you and your laborer mate are so keen to give it go, risk losing the insurance on the property, and possible electrocution to either or both of you, losing the refrigerant gas through bad pipe connections and who knows what else. Then I say Best of British luck to you.
