We called it to check and see if our system needed to be replaced. We was told that there was no charge for this. When the tech arrived 2 hours early we was not home. He called and said that the unit looked okay and the only thing he thinks needed to be done is freon topped off. We was given a price of 60.00 for the first pound and 36.00 for each additional pound. Our unit help 4 pounds and it only took 1.5 pounds to fill it up. Well we get home and are told the price we owe is 183.00????? They put it in as a full service call instead of checking to see if the unit needed to be replaced. They refused to adjust the amount or offer any form of reasoning. We called ..... for the same reason and they came out for FREE!! This place charged 105.00 will NEVER use again or recommend to anyone.
