NCG provided a competitive price for the supply and installation of a Mitsubishi aircon. The installation team arrived on-site on time and carried out the work in a very professional manner. Their attention to detail was excellent and I would recommend NCG to anyone who wants a high standard of workmanship.

Excellent affordable service. NCG Belleen has been amazing throughout the entire process, and has established itself as company whose services I have used multiple times. Even during these tough times, they maintained a clear line of communication at all times and allowed us to complete the job quickly and efficiently . Great place to buy all air conditioning needs. Bought 3 split system AC units. Prices were very competitive and was the cheapest I found in Melbourne.

Purchased an AC unit. Customer service from Alice in particular was amazing! She went above and beyond to help me out and was so nice to deal with. Rare these days to receive such great customer service. If I ever need another aircon unit, I will definitely purchase from NCG.

I found the NCG Air Conditioning team to be very responsive, professional, knowledgeable and friendly. We were provided with a quality product an excellent customer service from quote through to installation. The technician, Kingsley came out to inspect the house on time and recommended a heating and cooling system that suited the size of the house and our needs. Helen, from the office was friendly and helpful in making the bookings and keeping us informed. The installers did an outstanding fantastic quality work. I highly recommend NCG Air Conditioning to everyone.

I had a 2.5kw unit installed earlier this year in January by two NCG installers. The unit had stopped cooling within 2 months, I had other tradesman come in to look at the work done and they said to me: "these can't be done by a professional, what a joke!"
I did some digging and the workers names did not match the plumbers name on the appliance certificate so I am led to believe this company is full of unlicensed tradesmen (They spoke very poor English too). I do not recommend having NCG install your aircon unless you want something that will break within the year. These guys are the most dodgy
