Manufacturer Lennox Model # XC14-5036-230A-09 Serial # 5918E09348 Completed a preventative maintenance on a 8 year old Lennox air conditioner. I changed out the 16x25x1 filter. Then I took a temperature split it was 18. Made sure air conditioner drain line was working. Then I performed a amperage readings on the fan motor .75 amp and the compressor 8.2 amps the capacitor and contactor both look in good condition and are operating properly. The condenser coil was very clogged the client did have me clean the coil and also, paid for chud club membership. System is operating properly at this time.
