Performed diagnostic on air conditioner, system operating upon arrival but making a hissing noise and not cooling. Checked refrigerant levels found high side pressure at 350 with subcool of 50 and low side pressure of 65 with superheat of 5. Cleaned outdoor unit and indoor coil and checked pressures again, high side pressure dropped but still have subcool of 35 and pressures keep jumping up and down due to restriction in evaporator coil. Due to age, efficiency and condition recommend replacement. Need to return to review replacement options

Performed air conditioner tune up on 28 year old Day & Night. Unit is not cooling the home or removing humidity causing home to feel hotter than it should. This lead to high energy use and run time. Client wants to upgrade system to save money combined with their solar.

Performed tune up on air conditioner checked capacitors, contactor, electrical connections, refrigerant levels and amperage draw on compressor, condenser fan motor and blower. Air conditioner has three capacitors all are out of range, one is rated for 5mfd and is at .6mfd, another is rated for 7.5 and is at 3.8, the third is a 35 and is at 32.1. Contactor is badly burnt and pitted, system low on refrigerant and compressor amperage is very high. Blower is leaking oil and pulling high amps and blower capacitor is out of range rated for 10mfd and is at 1.8.
