A Tech came out to our house for another issue (window replacement - wrong tinting - came out 4 times to replace it then finally got it right) and confirmed for us that our Single Hung (Vertical Unit) was leaking from within the window unit and that it was a warranty issue. After sending pictures and advising them of what the Tech told us, they wanted to charge us $184 to look at the window again. The clerk setting up the appointment said that they would replace the glass if it was leaking. I advised that it was not coming from the glass, that it was coming from the interior, plastic, pvc structure. She was not willing to provide further information on how they would fix that or the cost, that the Tech would let us know. Sorry, but we are not interested in forking out money if you do not have any idea how much it will cost. We do not have any confidence in the after service of All Weather Windows.
