Our customer was hesitant about the potential cost of upgrading his electrical supply from 120 volt to 240 volt to accommodate a new air handler. Understanding his need, we came up with a great solution which not only saved him money, but also gave him an upgraded, high efficiency system. We provided a brand new ADP E furnace, designed to run off his existing 120 volts, and paired it perfectly with a brand new 20 seer Bosch heat pump. Our customer was thrilled with the outcome! He saved money, earned some rebates and is now the proud owner of a brand new high-efficiency Bosch ADP system.
