I found an amazing furnace made out of pure diamond deep within a cave. I have recently heard that there was a cave going deep into the earth in a mountain not far from my HVAC business. While I love my job as a local serviceman and air conditioner repairman, I also like to explore caves as a hobby. I decided to ask my friend Jim, who is a heating technician, to come along and explore the cave with me. We traveled for several hours deep into this cave and discovered that the walls were covered in beautiful diamonds. As we traveled deeper we felt that the key was getting warmer and warmer and a source of light was coming from within. We discovered that there was a furnace made out of solid diamond in the cave and it was releasing warm air all around us. This furnace looks like it had a geothermal heat pump in it and seemed like it was very efficient. I have been an HVAC technician for many years and have seen every kind of furnace going from a hot water boiler heating system to a zone controlled HVAC unit and even some old fashion portable space heaters, but I have never seen a furnace made out of diamond. We reported the furnace to a local cooling and heating company. After getting the furnace out of the cave we were rewarded millions and millions of dollars for finding this beautiful geothermal heat pump furnace. I was a little sad that the furnace had to be taken from ist beautiful environment, but now it could be used for good.
