  • Grotec is an incredibly professional and great value HVAC service provider. The quoting, booking and installation were seamless with a super fast turnaround making sure our house is heated for the rest of winter. Customer service from Grotec was also really great. Highly recommend!

    Really pleased with service from Daniel and the Grotec team. I had to have a split system replaced and two others serviced. All the work was done in a timely fashion, my house was left clean and tidy, and the installers took the time to explain the new system. An easy recommendation for me!

  • Would highly recommend Dan and team! They were friendly and reliable. Even though the weather was bad and it was a tight squeeze under the house they went above and beyond to fix my ducted heating issue. Super thankful!

    As the CEO of MMM Australia we needed a quality, quick response , and professional organisation to repair our office AC units. Daniel from Grotec Mechanical Services arrived on time, identified the issue and got our AC system back up and running quicker than expected. Great value, and great service. As a not-for-profit organisation we need to watch every dollar spent and Grotec have certainly looked after us. We highly recommend them.

    I cannot recommend Daniel and his team highly enough. They were professional in their approach from the time Daniel arrived to first look at an old system, sharing his knowledge and explaining what every step that needed to be done entailed. I would not hesitate to contact Grotec again.
