Customer has a 13 SEER 3ton AC installed in February 2015, and now the unit is not working--won't cool the home. Our technician Performed diagnostic on Heat pump unit it door condenser not turning on when there’s a call for cooling had 24 volt to the contactor coilbut not closing the contactor to allow unit to turn on. Replaced contactor and unit fire up immediately. Had bad Delta t coming from the supply’s 75 degrees coming everything pointing to low charge called Jerry senior tech of 30year to confirm low refrigerant and he agrees. Added 2 LB of R410A refrigerant delt T got better but still not within manufactures specks. Adding the refrigerant help bring my sub cool and liquid line pressures up but super heat was still high suction pressure low. Checked to see if expiation valve was freezing up and sure enough indoor TVX stuck. Added AC renew in hopes to unstick out door unit can take up to 2 weeks to see if it unstick TXV and no guarantee that it will. After 2 week and still having the same issue have us back out and well replace indoor expansion valve with new.

Customer's AC is leaking, and the customer is worried it might do damage to the ceiling. Would like to have it checked out. System was operational upon arrival. I looked for any water stains and could not find a definite location. After opening the indoor unit I found some pooling in the back of the condensate pan indicating that the unit was sloped back and not draining properly. After running the unit I found the indoor unit starting to frost up, which was an indication of low refrigerant charge. I checked the pressures and found that the unit was a little low and would need refrigerant to avoid icing up.
