My small 1BR apartment has an old gas furnace that works great, but costs my landlord too much to insure. He plans to install gas forced air, an in-unit upright furnace. I'd love to suggest a comparably priced alternative that will make less noise. What's out there?
edit: Maybe a few self-contained baseboard heaters and\or quartz infrared heaters could do the trick, for a small enough place? Mine is only about 700 sq ft. A similar unit in the building got a Rheem Criterion II gas furnace, so (@HerrBag) I'm afraid 90% may be overly optimistic.

The multi-stage burners are much quieter at low burn, as are multi speed/variable speed blower motors. These features are available for most 90% and higher furnaces.
A nice co-generation water heater (hot water for heat and a super storage unit for potable hot water) would be very quiet, but conversions costs to add radiators would not likely fly.
