Business ProfileforChas Roberts A/C & Plumbing

I had technicians from **** Roberts service my home on 9/6/24. I had no cool air on the 1st floor of my home.**** ROBERTS DIAGNOSIS: Upon arrival and talking to the home owner found it was tripped on the low pressure switch and found the leak was coming from the copper to aluminum side.**** ROBERTS REPAIR: Took out the remaining refrigerant and the joint. Replaced the joint and pressure tested to 260 and found no leaks.Vacuumed to 500 microns and added the refrigerant.RESULTS AFTER REPAIR: System is running and cooling properly. Payment of $924 was collected with credit card via square.Two days later no cold air on the 1st floor of the home again. Technician comes back on 09/20/24 to check the unit out. He tells he needs to charge me 200 for a diagnosis and that its probably in the attic. And says it would probably cost an additional 2300 dollars to fix. I sent the technician away and spoke with his supervisor. They sent an a different technician on 09/24/24 to diagnose and he found an additional leak. They notify me that it would be an additional 1300 dollars to what I have paid to fix the issue. My issue with the whole situation is that there was not a PROPER DIAGNOSIS to begin with and my money was taken without satisfactory results. I do not want to continue my business relationship with **** Roberts due to fear of being taken advantage of and service negligence. I would like to receive my hard earned money back because all of the refrigerant I paid for has leaked out due to negligence.
