I would recommend Air & Water if you are considering evap air conditioning.
We always do some research before Buying anything over $1000 and had many questions for their non pushy salesman before signing up.
Above all I wanted a system that is manufactured locally and is good value for money and that is exactly what I got with two whirly birds and an auto duct shutter included in the price.
Tradesmen were punctual, polite and tidy.

Approximate cost: $5500
