EXCELLENT Based on 49 reviews Mike Lafontaine21 February 2025Trustindex verifies that the original source of the review is Google. BJ and Max installed our new air conditioner and they were amazing no dramas - and very professional- five stars Donna Greasby31 January 2025Trustindex verifies that the original source of the review is Google. BJ and the boys have been fantastic spending the time finding the issue with our Actron air con. There have been quite a few hours spent over multiple days, changing several parts to find that it still wasn’t working, BJ spent the time navigating to find the issue and now we are back up and running. A big thank you to Sean who has been organising the entire job, Sean has been absolutely fantastic to deal with over the phone, he has been consistent in making sure that Actron delivered the parts we needed the following day, he absolutely done everything he could to get us back up and running.

I can't thank Andy and Jet enough for the huge effort it took to install my new split system and upgrade of my powerboard. My unit kept throwing curve balls at them through the installation and I was amazed at their positive can-do attitude and equally amazed that I heard no swearing! (Let me tell you I would have been blistering the air!) It took hours more than expected and Michael turned up to give them a hand to get it done. I know who to call on if I need any electrical work done in the future (although they may run screaming into the hills if they see my unit again!) The boys are a credit to your business and as a customer, I truly felt valued.

Thank you and all the best, Regards, Khang Chetan Khurana22 October 2022Trustindex verifies that the original source of the review is Google. We met Matt for our first home build for the electrical appointment. Considering we knew nothing in the electrical space, he helped us very patiently every time we had the conversation and never hesitated to help us not even once, twice but 50 times via email and phone. He was very easily approachable and very responsive on emails. He is 100% recommended for this service.
