HeaterFix gave us great service in replacing our Hurlcon HX120 spa heater. We didn’t expect to see it until November, but it arrived in a week and is installed. Well done Jason.

He had our Pool Heater installed a few weeks ago, and the advice on the best location and positioning was more than just fit and leave it was working within the space and surroundings to suit our needs. Price is important, but you always remember the quality. Thank You.

This is one professional Company. I had an issue with my gas spa heater. I spoke with Jason who guided me through a couple of self checks and finally isolate the problem. His advise and knowledge was outstanding. The parts were promptly sent, installed and operation is perfect. Highly recommended.
