The HVAC tech is here, well, he went to his truck for something. Have been without heat on two floors for four days now, it has not gotten too bad. I hope it is minor, duh, some part. We have a heat pump that runs on water. I guess these midrise buildings don't want to have any kind of outlet marring the exterior.
Be nice to have the heat on again, it's probably 60°F in my office. Our bedroom has a separate unit which is working fine on the third floor.
P.S. Heat back on, the tech said is was a "quick fix", the compressor is bad and he couldn't say how long it would last. $500 for a quick fix. It doesn't really sound great, I probably shoulda replaced it.
