Combustions chambers inside your home's heating and air-conditioning service are where the unit's fuel combines with oxygen transported through a bend in the return duct and another source of ignition to produce heat.
If you have gas furnaces in your home, the pilot switch is often the main source of ignition, and in electrics, central heating systems and electrics switches are used for this purpose. In furnaces that burn oil or gas, the fuel must first be exposed to air to vaporize so that it reaches the ignition switch for combustion. If a fault occurs during the evaporation phase, the chamber fills with water and collapses due to pressurized pressure.
In such circumstances, you may need to contact your heating and air conditioning service provider for a replacement. Depending on the types of HVAC systems installed in your home, your technician may install an open or sealed combustion chamber.
