Other 340MAV Reviews

Most comments about the Bryant 340 MAV relate to fixable problems.

One poster on diychatroom.com expressed concern about the control board flashing on the 340 MAV. HVAC contractors reported back that the control board was perhaps operating as it should; the flashing could indicate filter-replacement or coil cleaning is needed.

Posters on gardenweb.com point to the fact that Carrier, Bryant's parent company, settled a lawsuit in 2008 involving many of their high-efficiency models manufactured after 1989, including the 340 MAV. The settlement offers an extended warranty for owners; the premise of the lawsuit was that the models were not lasting as they should.
