Good guys is having a 20% off promotion, and panasonic is having a cashback promotion. Combine the two, and you can get a highly efficient air conditioning system for cheap cheap cheap. Regular listed price is $949
The panasonic promotion was set to expire on the 30/6, but its been extended for another month. Truly savy ozbargainers will snap up some cheap ebay gift cards to buy it with, bringing the price even lower.
They also have the following systems listed:
Panasonic CS/CU-Z35TKR3.5kw system for $1149($820 after discount)
Panasonic CU-Z71TKR 7.1kw for $1699($1159 after discount)
Once you have the unit, installation should be as easy as calling up a reputable air conditioner installer, and telling them you already have the unit and just need installation. It generally costs about $500 per unit for an average dwelling to get them installed, which makes it tempting to get a larger single unit, BUT the smaller units are often significantly more efficient. Its up to you to weigh the lower runnings costs VS the higher initial install costs, and see if it works for you.
Note, these have been pulled before, so it might be wise to act sooner rather than later if you want one. Also note there is a max of 4 claims per household. Full t&c here
Another thing to note is, that to claim you need a copy of the invoice. This is generated by The Good Guys from information on the ebay purchasers account, and cannot be changed. It needs to match the claimants details, or you may run into trouble. I got into an argument about it last time, the gist of it being that online orders have to be cancelled and redone, forfeiting the 20% discount.
Data point for those looking at these puppies … We have the 2.5 & 7.1 kw models listed. Both are fantastic units and very, very quite inside and out. Both use same remote. We can't fault them. We selected two different sizes for energy costs. The installer (swapping them out for existing old units) had no issues. I would happily buy again. YMMV
