Best Re Piping in Jacksonville FL

I will never use B&G again. Got Groupon for one time tuning from this company and the guy came as i was not home and i asked my wife to let the guy do tuning. The guy left certifying everything is good in his report and guess what a/c stopped cooling from the next day. I called B&G and they did send another guy now he inspect for more than 30 min and said nothing wrong he wasn’t sure whats was wrong. Then he said refrigerant is little low so he said he may need to fill little bit. At the end of it he said he filled 4lb. My point is if B&G has experienced technitians they how did the first guy certified that everythingis good and second guy came and filled 4lb refrigerant which they charged $260. Now you see here if we are not with them when they doing their job what happens. I strongly believe first guy removed refrigerant and second guy filled it back costed me money.
If refrigerant is really 4lbs low any amateur technician would identify that but it didnt happen that here.
I called them many times told about this and they said supervisor will call but they never called. B&G is Rippoff. Beware beware..
