My AC/Furnace has been a constant problem since I bought it 9 years ago. Even my service/sales company dropped the York (Johnson Controls) line 6 months after I bought it. Should have tipped me off. I'm just going to cover the inside evaporator coil unit. First evaporator failed after 3 years. The the second evaporator failed after 4 years. A couple of weeks later I received a Class Action Settlement covering these evaporators on almost all of the Johnson Control Air Conditioners (York, Fraser- Johnston, Luxaire, Coleman, Evcon Gruardian, Champion and Dayton). The settlement dictated that I had to have the service done by a Johnson Controls (jci) dealer in order to obtain the new, tin-plated, evaporator coils and they would reimburse me a couple of hundred dollars install charges. Being a retired 78-year old aerospace engineer, I inspected the new coil when the serviceman started to install it. York shipped the old model and they tried to slip it through. After the serviceman called York from the basement, it was evident that York knew it was the defective part and promised to ship the "tin-plated" coil in as soon as they were available. Finally the new coil arrived and we found that it was not an exact replacement and building new transition sheet metal would cost an additional $300. Electricity cost with the new coil raised my electric bill 20% from previous two years. Well, heating season is here and today I walked by my un-trustworthy York and found that the plastic evaporation collector was leaking all over the floor. All-in-all I estimate that I have paid out the purchase price of the a/c in non- warranty parts and labor to date. After the attempted fraud on the evaporator replacement, I will never trust the integrity of any jci hvac brands: York, Quantech, Tempmaster, Smartflex, Luxaire, Hitachi, Coleman, Guardian, Champion, and Miller-Picking.
