Quality control
September 17, 2025Had new Lennox Elite complete heat pump/AC system to replace the older 2018 unit from the same line. The tech said that even with the warranty, it would cost $8,000 to fix the old broken unit which had assorted problems, so I bought the new system because it was hot and they could put it in the next day. Install went fine. Two weeks later, the AC stopped cooling. The tech came out and found that a faulty internal soldered joint let all the coolant escape. Lennox agreed to replace the unit with a new one the next day, so at least they stand by their product. However, quality control seems to leave something to be desired if the joint failed so quickly.
