Thanks for clearing up the exact situation with your building. Now it sounds like the owner and/or contractor is trying to "fix" the system instead of ripping it out and putting in everything new. This is a familiar position, and it can, as in this instance, lead to time evaporation, which leads to upsets with building occupants.
It has to be realized that there are "those" times where a situation just gets icky and gets worse as with each tick of the clock. It is the old adage of the "Best Laid Plans of Mice and Men", and you get in the twilight zone somehow.
In your position, your trying to salvage the situation for your residents in some manner. It is the thought of "If I am sweating for a day I am pissed", and "If it looks like no one is doing anything and I am sweating for a week, then I am leaving".
Once the cool air is rushing in, the people will forget their pain, but will hold grudges against the building for a "while".
My suggestion once the situation is fixed, would be to draft up a letter to each tenant and fully explain why it took so long to fix it. Most people have the capability to understand, once they are no longer suffering. I find that most people being FULLY informed as to who, what, why and where something happened will be accepting of the facts.
If people just don't know exactly why something happened, then they will make up the reason for it, and they will roast the management over their preconceptions. After all, it HAS to be the manager's fault, right? LOL.
Good Luck!!
