From Jon C.

CDL Group of Companies
CDL is nothing but incompetents and liars. What kind of company won't give you any estimate on the work they do for you, even at the time of the job?
What kind of company will tell you they fixed your problem, only for it to break again just 4 days later?
What kind of company will charge you *again* to come out, and not *fix* it, but to tell you they will have to replace the unit to fix it (and not just for the workman's time but for a *second* freon charge)?
What kind of company will tell you, when you complain to them about it, that they'll remove the second charge, only to add it back to your bill two months later?
CDL is the kind of company that will pull this kind of crap. I wouldn't pay them to turn on a light switch at this point.
By the way, "poor-fair" doesn't cover the level of incompetence and underhandedness this company thrives in. "Horrible Failure" should be their quality.
