I had my old ducted heating unit replace with Brivis SP421e Gas Ducted Heater by Fairbairns. They were quick, professional with an excellent service from the quoting to the installation of the job. They even clean up the area around the unit for me. Rick who did the quote and install is one of the friendliest person to have a chat too. 5 stars from me and would recommend Fairbairns 100%.
