MagicAire Age?

Air Handler : M/N 030-DUX-A-10 ; S/N 951249086
I’m guessing 1995

That would be my guess, although I don’t have MagicAire in my 30-year-old furnace database. It’s a new one for me.

Me too. It was a very plain looking box, but seemingly functional heat pump air handler. The compressor was Lennox.
