I think Flanders Heating & Air Conditioning charged too much for their service. I called them to diagnose my air conditioning unit, and they told me I needed a new one. I was charged more than three hundred dollars just for that. I was charged again and for the same thing. I figured it was too much to pay, and nothing got fixed. I would hope that if I get a new A/C from them that those charges will be taken away but I do not know.
