Manufacturer Bryant Model # ACS036A2C1 Serial # L9908 52867 Completed a preventative maintenance on the heater and air conditioner. When I arrived I choose to check the air conditioner first. The split temperature was 22. I made sure the condensate pump was working I also changed out the 16x25x1 filter. Then I went out side and performed amperage readings on compressor 8.8 amps and condenser fan motor 1.0 amps then I made sure the capacitor and contactor are both working properly.

Then I cleaned the flame sensor. Cleaned out inducer port. After that I performed a amperage readings on the blower motor and inducer motor, both are in range of the furnace specs. Also, I made sure all electrical connections were tight and secure system is running properly at this point.
