I am 63 and have purchased many, many items both big & small in my life; this is by far the worst purchase I have ever made for both material & customer service. I replaced a 28 year old, still working, Bryant HVAC with this new York HVAC system. In obtaining quotes for "replacement" HVAC companies was giving me prices for what you would think is a new install, York dealers were by far the worst. My impression, worst than used car salesmen. Attempted to register the equipment online twice, twice wrote actual letters to York corporate asking them to confirm registration; no reply. Called twice and left messages; no reply. Emails; no reply.Now that evap coil has been identified as defective, and yes mine failed, in a class action suit, recently settled, in checking York website they are saying all 3 pieces of equipment I bought 2 1/2 yrs ago is still at the distributor, as I had surmised by their no response; not registered. York dealers will not return my phone calls because of my mistake of telling them up front that evap coil is to be replaced under warranty because sold knowing that it was defective according to court records. At one time York was the brand to buy, best in the business; now Will never ever buy anything with York name. Second house I own just last year had a Trane system newly installed. See cost them evan more in a lost sale. For now have to wait for settlement rep decide when and how much I am entitled to, evan tho will never recover for the hot period that we were without a/c and York dealer who recharged 2 yr old system with 3lb of refrigerant and cleaning that froze up again 2 weeks later. Common sense should have told him their was a leak with that much refrigerant needed.
