Upon arrival I began the furnace tune up. First, I ran a static pressure test. Your system has a max rating of .5 static pressure and your system is testing at .42 which is passing. Next, I checked the running amps on the inducer and blower motor and both were testing within manufacturer specifications. The capacitor for the blower motor is down to 3.82 out of 5mfd is at 76% which means it needs to be replaced. They can go up or down 6%, so 94% is the lowest they should go before replacement. Next, I did an inspection of the heat exchanger and found it has a crack in it that will start leaking carbon monoxide into the homes airstream.
