•Heating issues in Roswell Georgia. System was sending a safety code and put the heating system on a lock out . Was tripping the roll out safety device and this is due to the heat exchanger has damage took pictures and the burners are clogged with rust and misfiring/ underfiring . Would highly recommend replacing the furnace or a repair we could try would be to pull out the burner assembly and clean it but it’s no guarantee due to the heat exchanger . Family is aware of the situation. Will let us know what they want to do when they get back from thanksgiving.
