I purchased a York air conditioner Serial * WIG*******, and Model *YHM**B**SA, on October **, **** from the dealer:* Sansone Air Conditioning , *** Goolsby Blvd, Deerfield Beach, Fl *****. Since installation I have had ** service calls all relating to adjusting the functions in the air conditioning system and thermostat ,as well as replacing sensors, inverter, control board, and thermostat. Up to date the air conditioner is still not cooling properly and the new thermostat can not be connected to my wifi for continuous updates and other functions. I called Tony Duncan at Johnson Controls for North Florida and he was not able to help with any of these issues. I have requested that the air conditioner be changed or switched to another more simple model but I am always put on hold and nothing gets resolved. I have asked to speak to Nick Sansone, one of the owners that came to my house to supervise the installation of the York. He has not been of help at all. I have been in contact with John Gibbs, a manager at Sansone for the past year and as of October **, **** has not fixed this problem either. I have a very ill spouse at home which Sansone knows of his medical condition and so many times we have had to endure the failure of the York AC. The stress of all these issues has become overwhelming and the reason for my reaching out to you. I paid $**** for this air conditioner* I would like my money returned or replacement of a new air conditioner ASAP. I would very much appreciate your assistance in this matter.
