Thought I'd post an update since getting my 3rd split system installed by these guys. Wonderful, professional job as usual. I am very happy with my three new aircon units. The only minor thing I would like to point out is that my electrician went under the house and found some of the aircon electrical supply cabling was running loosely over the ground. For low-current cables this would be fine but seems to be a hazard for anything that draws a large current like an aircon. Other than that, thanks for your services as I am very happy with the units.
