The technician Justin came to diagnose the a.c. unit that was not cooling. He was at the house less than 20 minutes and said there was a leak in the coolant. He provided three options. Fill the coolant for $500, he would find the leak for $2000, or we could replace the unit for $5,000. The last option he highly recommended. Come on?!? I have owned several homes and had a.c. units serviced over the years. The system is 8 years old. The previous occupants of 5 years were at the house on a part time basis. I had a system in Florida that was 15 years old and still worked under heavy use. If there is in fact a leak, which I believe, where is the leak? How big is the leak? This is the job that I hired you to do. Telling me there is a leak in the system when it's not cooling is like telling me it gets warmer when the sun is out. Thank you Captain Obvious! My only conclusion about this company and technician is they are either incompetent, lazy, or just trying to hustle a new system. I think it's a combination of all listed. Stay away from this company. There are cost effective products available to seal leaks in a.c. systems. Costs about $70 for 1.5 ton to 5 ton unit commonly found in homes. Surprisingly the other a.c. company I contacted, offered this solution.
