Preventative maintenance on a Bryant standard efficiency gas furnace. Combustion analysis performed CO PPM 6. Homeowner replaced his own MERV 11-16x25x4 air filter. System was short cycling and addressed the issue by decreasing the gas pressure. The current temperature rise 33 degrees, manufacturer specs call for 30-60. There is a bypass humidifier mounted on supply plenum and connected to return drop. Completed the service on humidifier (#35 water panel Chud supplied). Humidifier was wired incorrectly. Corrected issue and tested for proper operation. System is now operating properly and not short cycling. Today’s charges are for the humidifier service and to rewire humidifier.
