*$15k for a ducted system seems way over priced, unless your house is 220m2 and not insulated?
Verbal estimate from two different heat pump installation companies, about four weeks ago. I got a quote for single systems, and just asked how much whole house would cost. This is for a regular sized but very old house, about 120 square meters not counting extensions that wouldn't need anything, double glazed and fairly well insulated.
$8K seems really cheap. What brand is it, and who sold / installed it?
Wasabi? Was quoted a couple dollars short of 3k for 2.7kw Daikan - back to back install. A $1200 unit, that was one very expensive install cost.
