Prior to calling out your tech for any adjustments to the boiler you should check the following:

What is the temperature in the room vs what temperature you would like? While the temperature in the room is scientific, the comfort level is subjective. It is important to know the actual temperature in the room to see if there is an issue with the system or you just want it to be warmer.
Are your radiators open? Very often people shut off their radiators due to some over heating that may have happened a few days ago and completely forget. Then a service tech is called out to check on the system, they don't understand what is going on, the boiler is working, the building has heat, but the apartment is cold.
Is your window open? Very strange to ask this question but oddly enough, we come out to a lot of service calls where the window was opened and then forgotten. New York apartments very often have poor windows that no longer lock which allows the top of the window to creep open without anyone noticing. This 1 inch gap can be the difference between a comfortable New York winter evening and a miserable one.
What is the temperature outside? Most heating systems are designed to turn off when the temperature outside goes above 55-56F.
