Upon arrival found air conditioner low on refrigerant Gave customer option of repair vs replace he wanted to go with the repair I let him no that any repair done on the system would not be covered by any warranty even if it’s the next day due to the air conditioner being r22 refrigerant. Gave option to do a leak test, vacuum test, refrigerant balance, and leak seal if any repairs are need we will discuss then. Customer only wanted to go with charging the air conditioner and adding leak seal Added 5lbs of r22 refrigerant, and added leak seal . Check vstat it was 41-42 which is perfect Check temperature split had 45degrees out of the supply and 75 coming into the return 30 degree split perfect. Check static pressure .16inwc on the supply side .51inwc on the return side recommend upgrading the return air for better efficiency Check contactor and capacitor 44/5mfd Check amp draws on the compressor 6.6amps and condenser fan motor.6amps Again no warranty comes with the work tod
