The furnaces were different from the a/c units in that they even recruited devices like smart thermostats and HEPA air purifiers
This is the story of the HVAC transformers war. It all began when an HVAC technician went a little far in his inventions of new heating and cooling units. He was trying to develop a robotic central air conditioner that could run on its own, even without a smart thermostat. After many trials and errors, he finally used a powerful coolant that did something strange to the central air conditioner, it transformed upright and developed a mind of its own. The HVAC scientist tried to shut down the central a/c unit, but to no avail. The air conditioner escaped the heating and cooling laboratory and began creating other HVAC units like itself. It made several live window air conditioners, a mini split air conditioner, and a few air purifiers. Soon enough there was a whole world of live cooling units throughout the world. The HVAC scientist decided he needed to develop a live furnace to combat the live a/c units roaming the world. He made a furnace and added to it an energy saving help so that it would be a little overpowered compared to the air conditioners. The furnace was complete and began going about making other live furnaces and heating units. The furnaces were different from the a/c units in that they even recruited devices like smart thermostats and HEPA air purifiers. Soon enough, the number of furnace and heater transformers matched the number of air conditioner transformers. Now, every heating and cooling business had hidden throughout their warehouses and stores. The heating and cooling war was about to begin.
