we purchased an air conditioner and a furnace from this company in 2008. In june 2017 the air conditioner did not work. we were told that our airconditioner was defunct and a new condenser at a cost of $21000 or a new air conditioner at a cost of $3800 were essential. we had another company fill with refrigerant and, FIVE years later, as of summer of 2022, it was still working. He was totally unwilling to help and obviously lacked the knowledge skills for this product.
