Informed Hot air furnace needs new gas valve and thermocouple should be replaced.

Thermocouple and gas valve replaced for $.
Told there was a bad heat exchanger and shouldn’t run furnace because of “flame rollback and CO”. Suggested they could replace entire unit, add A/C for about total of $ roughly. Scheduled estimate for replacement.
In the meantime, I googled issues furnace was having. #1 cause was dirty furnace. Since I was never offered to have furnace cleaned (sticker on furnace indicated last cleaning was ~5 yrs ago), I took it upon my self to do so. Heat exchanger was clogged with soot, ‘flame guard’ wasn’t attached.
A few YouTube’s, 10 screws, carefully cleaned and cleared, reattached flame guard. Furnace has zero rollout and acceptable CO after ‘thermally activated vent damper’ opens. Running furnace with no issues since.

In addition to hot air furnace, also inquired about a boiler replacement for other part of home, since it was old and getting rusty.

225K BTU unit. Other than transition ducting, all ductwork is already present.

276K BTU unit. Includes new circulatory (2), expansion tank, auto feeders, etc.
I'm only curious if this sounds reasonable for upstate NY (Capital region). I have no other way of determining if it is reasonable.
