Flue and Ducting System
Your Local Plumber specialise in servicing and maintaining these systems.
Nearly every central heating system we’re asked to fix has no filter on the fresh air inlet to the furnace. (Its a really good idea to have a filter) Air for the furnace is taken from inside your home. This means all the dust inside your house is sucked into your heater and then pumped around your house.
One of the first things Your Local Plumber will do is check this, recommend a filter, replace the main duct pipe and install a new fresh air duct. If you suffer from asthma or dust allergies this will make a huge difference.
