What I am going to express is not a question but a suggestion of what not to do. I am in Buenos Aires, I had a problem with the team and I called the [b] official Carrier service . [/B] He came and diagnosed that the evaporator forger was short. I charge the consultation $ 1,000.- a little expensive since other official services charge $ 400.- I spend the budget that amounted to $ 48,900.- The engine had some water so I stopped the equipment, I had it repaired and I had a hard time putting it to new $ 2,500.- I left the equipment running and the compressor was frozen at the time. So I had to buy a new 13.5 HP compressor. What was the problem that the Technician who charged his visit of $ 1,000. I changed the direction of rotation of the Forcer of the evaporator, so the turbine worked backwards, as it is in a very inaccessible place I did not realize it. It made me spend almost $ 30,000.- but it was less than the scam that I proposed from the beginning. As a result, I became an expert in central air conditioning, and I am already repairing all the equipment I have and those of my family. All for a technical evil that hurts the profession
