Energy safe Australia highly recommends servicing your gas appliances every 2 years. This is not only important to check for carbon monoxide, but also to check electrical components, gas pressure and to clean the unit and gas injectors. A dirty heater will not operate correctly and can also build up to much heat within the unit reducing its life. An efficient heater is not only safe, but cheaper to run. We do all repairs to heaters including replacement fans, ignition boxes and circuit boards. Call us to arrange a service today!
