No cooling, did a complete evaluation of entire AC system. Found suction pressure at 0 psi and high side pressure at 215 psi. Removed sensing bulb on TXV and suction pressure went up to 15 psi. There is a restriction in evaporator coil/TXV. Also filter dryer is very rusty and has refrigerant oil residue on it, capacitor is weak, and compressor has high startup amps. Gave client solutions for issues with system, however, system is 8 years old and recommended replacing due to age and cost of repairs. Client chose to go with solution #1 for now. Signed client up for annual membership. Need to return to replace evaporator coil/TXV, filter, dryer, capacitor, and install hard start kit. Scheduled to return on Friday, March 28.
