Whole house air conditioned for $5487 vs $14 000+ (+ cost of three phase power) as recommended by Coral. Our planned set up will be much more energy efficient too (Mitsu Heavy Industries with 5 start cooling efficiency). Ducted is a waste of money in single story homes in my opinion. Seems silly doesnt it - especially when we are doing the air con out of contract! They still insist on 3 phase for some reason??? We habe been thinking too maybe we are better off with a few split systems - biggest problem is our big open area....but will post plan & thoughts on my thread later - sorry op..back to you.
