2x furnace maintenance and inspection. Lennox furnace is in great condition, working safely and efficiently. Found no problems or concerns with this unit. Coleman furnace was not heating when i arrived. Ignitor had failed. Replaced ignitor and tested. Furnace would not successfully light on most attempts, only the first burner would light but flames would not travel down the assembly. Disassembled burner compartment and cleared rust out of burners. Furnace is now consistently lighting on a call for heat. This furnace is older and if it makes it through the winter i strongly recommend considering replacement next fall. Completed maintenance on this furnace after repair was done.
