Upon arrival I began the furnace tune up. First, I ran a static pressure test. This system has a maximum rating of .5 static pressure. Your system is testing at .44 which is below the max. Next, I checked the running amps on the blower and inducer motor and both were amping within specifications. Cleaned the flame sensor and cleared all the hoses and pressure switches. I took a temperature split on the system which was at 35 degrees which is within manufacturer specifications. If you have any questions or concerns please feel free to contact us!
