Improving a Suburban Furnace

[mcewena]

SF20 in my case.

It heats OK but it's just so **** noisy.

Has anybody modified the furnace to install a quieter fan? Less of an amp draw would be nice too.

We don't boondock enough to justify replacing it with a ductless diesel heater but that's probably the most economical solution.

My living room furnace is nice and quiet, but the bathroom one is a jet engine. Recently had the motor replaced so I'm not sure what happened there.

Haven't gotten to it yet, but my DIY is going to be a large resistor to try and slow down the fan speed. No, I'm not going to slow it down so much it'll overheat the furnace.
