The big risk with old furnaces is carbon monoxide leaks -- if your HVAC contractor is VERY confident that's not an issue, then the question becomes: Is it worth the short-term savings knowing that you'll likely get a call in the middle of the night one night from a tenant saying the furnace died?

That was so amazing... until everyone started fax-blasting you junk-fax and using up all your paper and carbon copy (remember that?).

They come new with a carbon filter, problem is, nobody ever changes them so they as you say just "spew them right back into the kitchen"Even with the filter, ventless still sucks IMO.

Because they work better, there's less air circulation which can damage the blower and cause overheating in the heat exchanger.Do you have carbon monoxide detectors?

At the very least, folks who have the ability to work from their homes leave less of a carbon footprint at minimum...

Are you going to blame someone else when the water heater back-drafts exhaust into your building and gives the occupants Carbon Monoxide poisoning?

There are no smoke detectors or carbon monoxide detectors in the house, which worries me somewhat given that there are tenants currently living inside.

The chimney liner is a safety issue, to prevent carbon monoxide from the combustion exhaust from penetrating through the chimney into living spaces.
