Have to rate the installation of our air conditioning systems very highly. It was a very difficult, unusual, complicated job into an existing 2 story household. Nothing asked was too much and our wishes were really listened too. The advice was great and the team, led impressively by Bill, went out of their way to do the runs and situations we requested, rather than taking any easy way out. At one point some painstaking work was reversed when a better solution was worked out over night. All of this done at no extra cost to ourselves. Also items were included that were subsequently tailor made and fitted to get the machines looking good and up and running in a couple of days. BMN worked hard, long hours and always obligingly. They communicated a perfect amount and we believe we were really lucky that we had the multiple air-con units installed by this company, because we doubt we would have got this type of service or the same results with anyone else - especially with the fixed price they had been contracted out at. As a side note we have since had them back for other electrical work with the same great results. We would thoroughly recommend them.
