I entered a thermostat building competition and my project was almost complete. I was the only HVAC contestant who built a smart thermostat. The other HVAC builders made thermostats of every kind including dial thermostats and programmable thermostats. Each thermostat had their own unique designs and perks, but my smart thermostat was one of a kind and the only smart thermostat entered in the competition. I had a central air conditioner to test my smart thermostat on and everything went perfectly. My smart thermostat was brilliant and advanced. I won the thermostat competition and took the prize home. I used the prize money to purchase some heating and cooling equipment at my local HVAC store. I began building my own unique mini air conditioner. I had worked on and seen many different portable space heaters, but rarely had I seen a portable mini split air conditioning unit. I built this air conditioner light and strong so it could be moved often and handled roughly without breaking. I entered the prototype of my portable mini split air conditioner to a HVAC factory where they approved the design and purchased the prototype and a/c care plan from me. I decided to make more HVAC units and sell them while getting a certain percentage of the profit. My portable mini split air conditioning unit sold everywhere in the nation and became a common and sometimes necessary asset to many HVAC customers. My creative mind is trying to come up with a new HVAC unit to build next, but this is proving difficult since there are so many heating and cooling units already in the world.
