Am I missing something here?

My apartment complex is doing its best to ensure that our electrical bills are as low as they can be by improving the quality of the buildings in which we live. Most of the buildings (including mine) have new roofs, and they are in the process of replacing all of the windows with ones that are guaranteed to be more energy efficient. The addition of siding to all of the buildings is also partway done, which adds yet another insulatory layer to prevent internal heat loss.

Well, my apartment's windows on the East side were newly installed when I first moved in, and today, workmen came by to replace my West-facing windows. I only have two windows on that side, and performed all of the preliminary steps which were requested of me by the complex management (moving all objects away from the windows to allow the workmen space to work.

When I was at home with my folks, we had to replace a few windows. My father removed two windows and installed their replacements in a span of about an hour. Admittedly, these fellows have a bit more work to do, since they have to also remove and install new blinds for the windows as well.

That said, it seems as if they are taking their sweet time in finishing the work. They showed up at my front door at 8:15 am this morning. They promptly removed my windows which were out by about 8:40, leaving two gaping holes into the world outside in my front room. Believe it or not, they still have not finished installing the windows, and it is now 1:20 pm. According to my thermometer (which I look at when I wake up) the termperature of my apartment has now plummeted from a balmy 76 degrees (it heats up at night for some reason) down to a chilly 57 degrees. I've had to put on another layer of clothes to remain warm in my own house due to their slow rate of work.

I'm sure I'm missing something, but they haven't even installed the blinds yet. Shouldn't they be gone by now?
