At a house today built in the late 70’s. Exterior two flue chimney. First floor fireplace, and a flue for the gas fired furnace/water heater from the basement. Two story plus maybe10 feet above the clg. elevation.
So I go to the roof to demo the old broken mortar cap. Once it’s off I see the two flues are swaying free inside this one brick thick chimney.
Was that code in ’79-’80? I understood it to be 8″ solid masonry around the flues. Do you think this is safe?
As the industry phases out R-410A due to environmental regulations, new refrigerant options—R-32 and R-454B—offer lower global warming potential, but the best choice depends on your technician's training and familiarity with these newer systems.

It should have had a wythe course between the two flue liners.

Yours is better. This one is 24 x 32. one 8x8 flue, one 10x10. Maybe 3 inches between. Lot of space. Flues not tied in with wire or anything.

Thats not my work - masons working on a house that I've got a photo thread going were the ones who rebuilt this top.
Sounds like a Pulte home.
I've seen that, seen the flues packed around solid with masonry also, niether is correct, but both are still better than any of the metal chimneys that most popular.
