The aliens made an Heating and A/C machine with toxic fumes in it.
When both of us first met the aliens, both of us thought they would help us advance our Heating and A/C industry.
Every one of us wanted to suppose more about a/c plus get a better understanding of indoor air cleaning systems. Every one of us helped the airlines develop better commercial a/c units plus oil furnace replacement. In return they showed us a up-to-date style of coolant that could be put into a central a/c or gas oil furnace. They claimed that this coolant could outdo our geothermal heat pumps plus hybrid Heating and A/C units in efficiency. Every one of us decided to put this coolant to the test in our Heating and A/C lab. At the lab both of us have the world’s leading Heating and A/C servicemans, cooling specialists, plus heating servicemans. When both of us put the coolant into our test central a/c, the air that came out was extremely toxic. All of the Heating and A/C servicemans fell to the ground clenching their throats. One local repair woman who was there for observation was able to turn on many whole home media air cleaners, and some a/cs that had HEPA air filters in them. The air cleared up just in time. If the toxic air had come any longer, several of the Heating and A/C servicemans plus heating servicemans would have died! Every one of us told the aliens to take back theri coolant plus leave us to do our own read on indoor air cleaning systems plus central a/cs. To this day both of us do not suppose the intent of the aliens. Many think they were trying to take over the world through our central a/cs, gas oil furnaces, space heaters, plus any other Heating and A/C machine that the coolant could be used in. If that was the plan, both of us are thankful both of us have developed excellent indoor air cleaning systems.
