I just wanted to say thank you very much for your great service in repairing and checking my Evap. Cooler. Everything is working well and I appreciate the Service Manager coming out to check the motor, after I mentioned something wasn\’t quite right. I also want to thank Odette in the office, for providing fantastic first point of contact and booking in the service visit, without any fuss. I wouldn’t hesitate to use you again and highly recommend you to all home owners!
We would like to thank Cathy who booked our evaporative cooler repair last Monday and the technicians Joey and his assistant Tyson who came on the Wednesday. The professionalism we received from the moment we called to the completion of our service was fantastic and we both want to say a sincere thank you and will make sure if we need any further assistance who we will be calling.

We received fantastic customer service from the team at Gastek to attend to our broken gas ducted heater. At the beginning of winter, Cathy was so helpful to fit us in within 48 hours as we had a 6 month old baby and overseas visitors staying with us. Other companies had us waiting for over a week. Chris, the technician, spent a good hour thoroughly problem solving the fault and was able to fix it on the spot. Thanks for being so warm and responsive when we rang for assistance. We will recommend Gastek to our friends and family.
