Completed one ccm maintenance on gas furnace located in attic i checked both thermostat operations and zoning system. I checked gas and exhaust to ensure they were safe to operate, i pulled and cleaned flame sensor, I pulled and cleared pressure tube. I checked low voltage wiring for any loose wires I changed one 16x25x5 filter. I watched unit cycle getting inducer amps and blower amps. I checked delta T as well. Everything is well within system specifications, system operating normally as it is still very new. Pics uploaded to ST
