If you choose Capital Air be very careful to ensure they install the system correctly.
I purchased a Daikin split system; the compressor unit was installed on a large garden paver (by Capital Air) on top of the turf which was on a fall away from the house.
Over time, the grass died and the paver shifted - risking damage to my rainwater tank and causing premature wear of the bearings as the system was running without being level.
Capital Air just quoted me half the cost of the system to re-install the system on a new base and to replace the motor bearings of the motor, taking no responsibility for the substandard installation.
If you request a quote from Capital Air, be very careful to ensure they install the system properly as it will cost you in the long run if you let them get away with sloppy installation work.
They have yet to take any responsibility; instead, they blame 'rainfall'.
If they accept some responsibility I will update and would recommend Capital Air. I would not recommend them otherwise.

Approximate cost: $3700
