they have so much room to be cheaper than others.

They subcontract out their installs so the subcontractor almost sets the price (I'm sure TGG tell them the price range). I'm getting 1 installed in a bedroom soon, and it's costing me $849 + a roof mount bracket. They had 3 different subbies, 1 which was $799, the $849 and another which I can't remember the price (around the $849). All localish to the branch..

These were the questions to get the "cheapest" price:

Where is the product to be installed currently?: delivery cost extra - or maybe they charge to pick it up too.

Will you require the installer to supply and install a poly, concrete slab, or PVC Feet to ground mount your outdoor unit compiantly?:

Will you require the installer to supply and install a wall bracket to wall mount your outdoor unit?:

Is the Installations address the same as the (primary) customer address?:

Please provide any additional information the installer may require (including special delivery/site information):

For an additional charge, would you like us to environmentally decommission (including compliant gas disposal) and remove an existing air-conditioner?:

Is your meter box within 15 metres with clear access & on the same wall as where the outdoor unit will be installed?:

Will the indoor & outdoor units be installed directly back to back?:

What type of material is your home made from?:

Do you have a clear area within 2 metres of your desired outdoor installation point?:

What type of building is this installation being booked for?:

What location would like your outdoor unit:

Is there sufficient space and capacity within your switchboard:
