Upon arrival I completed diagnostics and found the problem ended up being a GFI outlet was tripped. Client had concerns about a dirty evaporator coil due to his filter not being in properly. Customer was made aware of it and does not want to do anything more at this point. Customer did not have a T safety switch on the evap coil pan, client opted to have us install one. Client was asking about fall and summer tuneups, technicians went ahead and did an AC tuneup while we were here. Everything checked out except for the unit was slightly low on refrigerant. Client opted for us to charge the system to the proper levels. AC system is operating within manufacture specs.
