Arrived onsite to perform annual safety and maintenance inspection. Began by kicking on the furnace and testing my inlet gas pressure which gave me a reading of 7.45. Tested my flame sensor and gave me a reading of 2.6 microfarads. Tested my blower and it was pulling 7.83A. Tested inducer was pulling 2.04A. Measured for my delta T and got an air temp differential of 45Â°. Changed out 20 x 20 x 4 filter. Tested for CO in the home found none. Ensured everything was working properly upon leaving.
