boiler heat. There are three thermostats that control the heat on the different levels. The thermostats on the top floors are set at 68 sometimes lower but the heat keeps coming out even when the thermostat is reading it is 80+ in here. The thermostat on the ground level seems to be working fine. They are the dial system. Is it the thermostats that need repaired? Is this something that can be done easily? How expensive?

JUST A REFERENCE; Unit designed to heat 900 sqft. 300 sqft per thermostat. When heat comes on and only 1 zone is calling the unit doesn't heat 1/3. It heats the 900sqft it's designed to. Therefore that "extra heat" HAS TO go somewhere. If it doesnt go to the "non calling" zones the unit would shut down on safety because it would get too hot. So, open a window or you need a bypass damper with bypass duct installed that when the heat comes on for only one zone that "bypass" opens and sends the "extra heat" back into the return rather than to the "non calling" zones. To answer your question, nothing is wrong with your unit or tstats, it's the duct work. Maybe $600 to $800
