I give One star because I can not give ZERO. Wish I could give a negative number. My wife was home alone when the service tech arrived. We had a service performed on our a/c unit and everything worked fine before Emanuel Nino arrived. After being at the a/c unit for nearly 45 minutes, now the a/c unit does NOT work at all. He returns to say that he found an issue, but it will cost $840.00+ to get it working correctly. He also stated he was going to set her up with (NOT recommend, but set it up) another service plan to 'make sure this doesn't happen again'. My wife said no to all of it and said she will speak with me when I get home. I arrive and we call A#1 back and complain. They send another tech to us. He is at the a/c unit for about 3 minutes, returns and says the other tech left a connection open in the box. He reattached it and WOW... THE A/C WORKS NOW!!!!!!!! INCREDIBLE!!!!! We mentioned what the other tech, Emanuel said and this tech said that is completely unnecessary, everything works good now,. What we dealt with was one of the shadiest scams by an Air Conditioning Tech. Preyed upon a woman home alone and does something minor to make the unit fail, but for several hundred dollars he can fix everything... then reconnect the wire, or whatever he did and turn in a high ticket invoice to the company and he in turn gets paid for the work. I will be contacting the Better Business Bureau and any and all Corporate personnel with A#1 Air. this is sad, simply because we have used A#1 Air for nearly 10 years, and never had an issue until now. I find Emanuel Nino to be very dishonest and preying upon a woman home alone to make a high dollar repair, when no repair is needed, shows extreme lack of character and morals.
