We just bought a new house and we have an old air handler in the attic. There is little to no insulation on the air handler itself. The ducts have minimal insulation. We are looking at replacing the whole unit and ducts.
We have an oil based boiler that feeds a hyrdonic heater in our air handler.
I've been looking at the Trane Hyperion which seems like a novel idea of constructing it like a refrigerator.
Any other good air handlers out there for the attic? I hate losing heat to the attic. We live in Boston area. Thanks.
