  • review rating 5  My Gas Ducted Heating broke down. Geoff was recommended by another member of the Mt Martha Community. Geoff was very easy to talk to, responsive, quick to assess the cause of the fault and prompt to install a new Digital Thermostat. Geoff will be my “Go To” Gas Plumber from now on.
