Villains are evil, but if someone is an Heating plus Air Conditioning villain you better watch out! It was discovered that an evil villain was somehow using Heating plus Air Conditioning units to destroy the world. At any given point, he could trigger an air conditioning system or oil furnace plus cause it to spew out toxic poison. He seemed to only target his enemies. Everyone was scared to use their oil heating systems plus central air conditioning systems, plus instead they just ran their whole loft media air cleaners to make sure their air was free of toxins. Heating plus Air Conditioning specialists plus cooling specialists all over the world were trying to find the source of these Heating plus Air Conditioning attacks. I was a young heating specialist when I started trying to find the problem. I had built several of our own media media air cleaners, window air conditioning systems, plus gas oil heating systems before, plus none of them had the toxin problem. I soon discovered that the safest heating units to run in your loft were the portable space heating systems plus the hybrid oil furnace. I did some more research plus found that a mini break air conditioning system was the best cooling option. The government hired myself and others to use 1 of our Heating plus Air Conditioning units as a mock Heating plus Air Conditioning component 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 conditioning system or oil 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 media media air cleaners that could filter out the toxins. Soon we would find the enemy.
