Performed scheduled furnace tune-up on 26-year-old Payne furnace. Combustion analysis showed CO readings reaching 185 PPM (below immediate tag-out threshold but concerning). Identified blower motor with excessive play and capacitor reading 2.2/5. Educated homeowner on proper air filter replacement, orientation, and the significance of elevated CO readings. Recommended scheduling next maintenance in early fall to address potential safety concerns before heating season.
