This company was selected by our home warranty program to diagnose our upstairs A/c unit that had gone out. The technicians came out and told us it was the capacitor and then proceeded to tell us it was old and that our unit needed replacing and that would not all be covered by American Home Shield and our responsibility would be about $5000. Having been American Home Shield customers for almost two decades, I knew that was wrong as they replaced our A/C unit in two separate houses (we're military) over the years with no extra cost to us besides the service fee. In any case, York Mechanical never submitted this work order to AHS and I had to call again to have them come out and run a new one. I also called American Home Shield who assured us three times that ALL they needed was a diagnostic report from York Mechanical so we could get the authorization for a new unit. John, the service manager, came by again to run a new diagnostic to submit to AHS and before he even made it two steps into my home (I was alone at home with my children) he began snarking at me telling me, that this visit was basically pointless, telling me he knew the ins and outs of MY warranty plan and I still was going to have to pay them money out of pocket (in addition to the money they would receive from our warranty program). I told him what my experience with AHS was and told him I just needed him to run a diagnostic and then he snapped at me again, telling me he's done this for 17 years and we were going to have to pay York Mechanical out of pocket. I told him he was upsetting me with his Unprofessionalism and that I was going to call my husband (because I no longer felt safe with this man in my home with me and my small children) . The minute I started explaining to my husband what was going on, John started yelling at me from my front hall saying that he didn't say what he said and then stormed out of my house, refusing to run the diagnostic. I called York Mechanical immediately after this to report him, was told by Michelle that no one was available to speak to, so I told her what happened...she sounded like she couldn't care less. I then called American Home Shield and told them what happened. American Home Shield explained to me that York Mechanical had no business discussing financials with me at all as they are supposed to diagnose the problem, come up with a solution and the cost and send it to AHS for review. AHS then looks over their invoice/work order to make sure the charges match the work that is being done and then they look at our plan to see what is covered and then THEY tell us what, if anything, we are responsible for. As it was, York Mechanical never even submitted the first diagnostic test to AHS (which is why I had to call them in again) and it seemed very much like they had no intention of submitting the one they had come again to do until we agreed to the $5000 out of pocket fee...which is the only reason I can think of as to why a technician (who was simply coming to run a diagnostic test for our warranty company) would start his service call by telling me I would be responsible for out of pockets costs and when I pushed back and told him we'd let AHS decide that, he got angry and left without doing the diagnostic at all. When my husband got home, he talked to Don (the manager of York Mechanical) who told him I had verbally abused his technician (by refuting his assessment of MY warranty coverage, I suppose) and then told my husband again that we had to pay them money out of pocket. When my husband told him what AHS told us, he got extremely defensive and accused my husband of attacking his character. Undeterred, my husband asked him why they never sent the original work order to AHS...Don blamed us for not agreeing to the $5000 on top of whatever AHS would cover quote they gave us. Again, that's not how that's supposed to work. AHS calls the contractor, the contractor calls us, sets up an appointment, checks the problem and submits the findings to AHS for review and authorization. AHS then contacts US to tell us what, if anything, we have to pay outside of our warranty. Once we agree to the terms set by AHS, AHS then authorizes the work to be done. Instead, it seems, York Mechanical wanted us to agree to their extra fee (without authorization from AHS) first and then wanted to turn around and get more money from our warranty plan...I'll let the proper authorities be the judge of that, though - because you better believe I've contacted the consumer board. In any case, steer clear of this company if you can. Besides their shady business dealings, just about every person we dealt with was rude and unprofessional.
