Carl said."I've spent the last two years sweltering in my tiny office. People are always adjusting the thermostat upward. it's in the next room. They raise the temperature. I go in there and lower it. They turn it up again. I've asked the boss to put a locked case on the thermostat. Also, I learned that half the tubing for the ceiling vent in here is disconnected. Every six months or so, the HVAC guy comes by. I tell him about this problem. He always says he's going to fix it. Then I don't see him again for another six months. I sweat all winter. I sweat all summer. it's ridiculous!? Yolanda said."Have you ever considered this fancy new technology they just invented? It 's only about $25, but it cools a room very well." Carl asked."Really? only $25? What is it?" She said."it's called a fan!"
