I had a 5.4kw Fujitsu split system installed on an internal wall. This was a tricky position from which to access the external unit but Dan and Jezza managed this job with ease. Dan was the only one to offer a solution that did not require exposed ducting to internal walls or repairs to plaster work after the install. They were totally professional and courteous and cleaned up before they left. It's also great to have the man who quotes the job actually do the install. My only regret is that I didn't look up this website and find out about Ezy Air when I had an A/C installed in the past. Highly recommended. The great price was just a bonus
