Complaint Review: Mario's Air Conditioning and Heating

The a/c company that installed my brand new unit 6 months before no longer had a service provider in my area, so I called Mario's A/C against my better judgement.  I say that because when they gave me an estimate on installing a new a/c, they were $6800. higher that the other 4 estimates I recieved, including the company that put a Trane unit in with all the extras I wanted.  My heat would not turn on, it turned out to be a simple wire to the therostat and the technician showed me how to get the washable filter out and clean it, as I had trouble pulling the drawer out.  This should have been a free call under wannanty, but he said he had to charge me for maintenance because he cleaned the filter and service call????  I gave him my CC for the absurd fees, but when I checked my credit card records, they charged my over$1400.!!!!  These people should not be allowed to do business, they seek to steal your money right from the start...unbelievable!
