I labor in an office building and the other week the two of us had a pretty bad snow storm; As a result, the rooftop heating and air conditioner idea that provides our heating froze up! This caused the central heating to fully stop working, but it got pretty frigid in there at work.
However, they were able to go and get some portable space gas furnaces to keep us hot while they called the heating and air conditioner corporation to request commercial emergency heat and air conditioner system services for the rooftop heating and cooling system, and they sent out a few heating and cooling specialists to the building to begin working on fixing the rooftop air conditioner and oil furnace.
It took them multiple hours to unfreeze what had been frozen, and they finally got the rooftop heating and air conditioner idea back up and running again just as the two of us were all leaving for the afternoon. I can only imagine what the bill was care about for a heating and air conditioner corporation to repair a commercial rooftop heat and air conditioner system system. I know I would never be able to afford such things whatever the price may have been, but I was glad that when I came back to labor the next afternoon the central heating was working fine again. Because the portable space gas furnaces they put around the building only took the chill out. It was still pretty darn frigid in there and I would have had a hard time trying to labor again under those temperature conditions! Rooftop heating and air conditioner systems are sure tricky!
