Villains are evil, but if someone is an Heating, Ventilation and A/C villain you better watch out! It was discovered that an evil villain was somehow using Heating, Ventilation and A/C units to destroy the world.
At any given point, he could trigger an air conditioner or furnace plus cause it to spew out toxic poison.
He seemed to only target his enemies. Everyone was scared to use their furnaces plus central air conditioners, plus instead they just ran their whole house media air cleaners to make sure their air was free of toxins. Heating, Ventilation and A/C professionals plus cooling specialists all over the world were trying to find the source of these Heating, Ventilation and A/C attacks. I was a young heating professional when I started trying to find the problem. I had built many of my own whole-house air purifiers, window air conditioners, plus heating systems before, plus none of them had the toxin problem. I soon discovered that the safest heating units to run in your house were the portable space heating systems plus the hybrid heating system. I did some more research plus found that a mini break air conditioner was the best cooling option. The government hired me to use 1 of my Heating, Ventilation and A/C units as a mock Heating, Ventilation and A/C unit in order to find out where the toxins were coming from. I had a suspicion that there was some kind of signal sent to the air conditioner or furnace that made it release toxins into the HVAC ducts. This toxin could seep through any HEPA air filter plus most other air filters. There is a certain line of whole-house air purifiers that could filter out the toxins. Soon all of us would find the enemy.
