Arrived to perform a friends and family air conditioning maintenance upon inspection. The technician found that the air conditioner is overcharged with refrigerant with the system being overcharged the unit has to work harder to compress the refrigerant, as well as cool it down. The system will wear out prematurely, and the unit will run more when it is hot outside. The technician also found that there is a lack of return plenums, causing the blower motor to have to work harder to pull air from the home as well as the supply. Plenum is too small not allowing the airflow to distribute properly and evenly. The technician recommends, adding to return plenums, as well as replacing the supply Plenum, and pulling some refrigerant from the system to balance the charge correctly and help the unit run as designed. Will return Monday the 15th to install one new 21 inch wide supply Plenum with proper height install new duct takeoffs as well as install two new 16 x 25 return plenums with 1 12 inch
