Top-floor unit overheating in winter
On a shared boiler, the top unit may get more heat than it needs. Thermostatic radiator valves or zoning can tame it without starving the floors below.

A furnace that runs a few minutes and stops is often oversized for the house or overheating from a clogged filter or restricted return. Both are fixable.
Older two-flats were wired before air conditioning was common. Mini splits draw less power than several window units and run on their own circuit.
If your two-flat shares a boiler, splitting it into two zones with their own thermostats is usually simpler and cheaper than installing two new furnaces. The radiators stay, and each unit controls its own heat.
If you’re converting to forced air, plan ducts for both heating and cooling at once. Ductwork sized only for heat often struggles once central air is added.

Yes. Zone valves or separate circulators let each unit have its own thermostat on a shared boiler. The piping layout decides how simple it is.
It depends on the association. Many allow them with rules on outdoor unit placement and line set routes. Ask the board first, then get the estimate.
Start with the filter and make sure supply and return vents aren’t blocked. If it still shuts off, it may be overheating or a safety switch may be failing, which needs a technician.
