Duo Therm Heat Pump Repair Problems in artbalog's Blog A blog by artbalog@aol.com Posted November 20, 2010 · Report reply If the units can't be recharged it is doubtfull that the freon can be checked. I doubt that the service tech knows that it is low. the problem is probably the compressor. I have experienced this in the past and it was better to replace the unit.
