My central heating and air conditioning system had broken down not too long ago and it was a very strange situation.
It had broke down and I had to go to a hotel for the night.
And so I called a local heating and air conditioning specialist to come out and repair the central heat and a/c unit the following day. When that next day arrived I left the hotel and headed back to my house to meet the local heating and air conditioning worker I had called to repair my central HVAC system unit. Well, would you know that when I arrived back home and went in the house the HVAC unit was working just fine? I do not know what was going on, but I was thinking that I was going to look like the biggest moron on the face of the planet! It was embarrassing when the heating and air conditioning worker arrived to tell him what just happened and I was thinking that he was going to be mad and look at me like I am some lunatic. However it was not in the least surprised and told me that this was just a temporary thing and he had seen this happen before. I do not know exactly what he did or replaced, but it was this little box inside the central heating and air conditioning system unit. He said that this was the problem and that if he does not replace whatever this box is, the central heating and air conditioning system will die for good next time. This all was something totally normal.
