Mold Inside Older Furnace

I recently attempted to get my furnace serviced and the tech indicated that there was mold inside the furnace on the insulation. Under normal circumstances I would replace the unit. Unfortunately the furnace is in an older condominium where the furnace/heating system cannot be shut down without shutting down the entire community. So, replacing the unit won't be an option until Spring. Until then I need to insure that mold spores are not being filtered through the system and condo.

Is it possible to safely remove and replace the affected insulation? If so,

1. Is this something that a homeowner could do wearing the right protective gear?
2. Is there a certain type of insulation, specific to furnaces, that should be used?

The furnace is probably original to the condo and 30+ years old. I don't know the manufacturer or model number. Unfortunately the tech had no interest in addressing the mold and I'm not even sure if it's something I should expect him to do.

Thanks for any advice and suggestions.
