Re: Furnace vibration
Depends on the type of blower. belt drive or direct drive? misalignment of the belt to sheave. improperly installed sheave. loose mounts, etc.
The classic is the wiring diagram or any papers falling into the squirrel cage.

Re: Furnace vibration
loose mounting, improper assembly of the new parts. loose set screws on the blower bent or damaged blower wheel, disintegrated resilient mounts.

Re: Furnace vibration
Nobody knows until you get to the job. Who know what the other tech did, he could have bent the motor shaft or damaged the blower. What was the original call that made him replace those parts.?
Re: Radiators make my apartment unbearable during winter
The system may be working as designed, it may just be a poor design. If there is no thermostat on your floor how would the system know when to stop heating the third floor ?
It would not surprise me if the seal in the valves were intentionally removed at some point.
Seems you may be stuck between a landlord that just does not care and the law that may just deal with minimum temperatures.
I think that's why the other folks offered other ban-aid type remedies. You are not the first to have this situation.

So let's proceed, with cautious optimism but realistic expectations. We are certainly happy to help you as much as we can!!
Re: Radiators make my apartment unbearable during winter
You mentioned two thermostats. Anyway to know which thermostat controls what? You mentioned one tenant on the third floor that's having similar issues. Would probably be somewhat helpful to know if other apartments are having similar issues.
Re: Radiators make my apartment unbearable during winter
The first part, of this last post, might be somewhat inaccurate. Thermostat only knows the temperature of its particular location. For example, if there are 10 rooms and the thermostat is in room number four, it only knows the temperature of room number four. Or in your case, if the thermostat is in the hallway, it only knows the temperature in the hallway and only reacts based on that temperature. Covering your particular radiators would have zero effect on the thermostat.

If it's just the threads, drain system, back out well, re-tape, re-install (which may or may not be possible with your tank).
Re: Vent placement in home 2-pipe steam heat system
Didn't realiuse that.
However… may I humbly point out that steam systems don't know anything about the gauge pressure? Or vacuum? All they know is the pressure differential. So, to take the above comments on the Empire State Building as an example, lets' suppose that they have a steam feed pressure of 2 psi GAUGE and are operating at 10 inches vacuum. Now 10 inches vacuum is almost exactly - 5 psi GAIGE so that the building is operating on a pressure differential of 7 psi. It will in fact — except for temperature of the radiation — operate in exactly the same way with a boiler pressure of 7 psi GAUGE and open vents or, for that matter if you could get there, - 5 psi GAUGE at the boiler (10 inches of vacuum at the boiler) and 20 inches of vacuum on the returns…
Bottom line. If you really want to understand what is going on in a steam system, always work in absolute pressure and differential pressure. Gauge pressure and inches vacuum with trip you every time.
