I've used Grotec for several times now and always found their service 5 star, from the Administration department their field technicians, also the communication skills is fantastic. They also organised the electrician to installed our isolator switch, which was done the same day. Keep up the exceptional customer service team, also special mentioned to Daniel ðŸ‘ðŸ¼

 Trustindex verifies that the original source of the review is Google. This morning (Fri 21 Nov 2025) my AC unit in Brunswick Eastâ€™s apartment block was serviced by your employee, Josh. Both my husband and I are very impressed with the man.Â  He was punctual, courteous, competent, quick, neat, careful in his duties and genuinely pleasant in course of our interactions. He displayed the highest level of  professionalism. Thank you. Irena Goltz

 Trustindex verifies that the original source of the review is Google. Can not recommend Grotec highly enough. I had my out dated ducted system replaced and can not believe the difference it's made. Super impressed with the service from start to finish and no mess whatsoever so ever left behind. FINALY looking forward to a cool house this summer!!! Big thanks to Daniel and the crew at Grotec Air Conditioning for the advice, install and overall service!!! Mark Yarra Valley !!
