I arrived for a silver member fall maintenance. I first inspected the filters and found both filters to be dirty. I replaced with ones the homeowner provided. I then inspected the furnace and found the system to be in the same condition as last service. I cycled the furnace on and checked all electrical components gas pressures and temperature rise. I found two leaks in the gas line at the furnace. I made the homeowner aware of this issue and and we decided to reface and pipe dope both components. I repaired both leaks and rechecked the gas line. I found no other issues at this time.
