At my home we had a ducted system installed over 15 years ago by Fairbairns, a split system about 5 years ago and just had the ducted unit replaced with a 6 star unit.
Each time Fairbairns have been reliable and friendly. We also use Fairbairns at the College I work at and the same applies when they are there as well.
Would have no hesitation in recommending Rick and his crew to anyone.

Approximate cost: $3500
