I am an HVAC technician, and I have spent my life building central air conditioners, window air conditioners, furnaces, and air purifiers. I have studied all of the workings of these HVAC units, and have extensive notes on my HVAC blog about them. I have done research on the best kind of air filters, adn the best kinds of smart thermostats, but one question still remains, what would it take to get the perfect HVAC unit. I am working on inventing this perfect HVAC unit, one that has air conditioning, a furnace, and air purifying system, and a smart thermostat all connected. I would also like to incorporate a zone controlled HVAC system in it, and a way to connect it to floors so that it can produce heated floors. I want this HVAC unit to look sleek and shart, and to run smoothly. I began building this perfect HVAC unit later one night, when my mind works best. First I developed the central air conditioner part of the HVAC unit. I have built thousands of central air conditioners, but I made sure that this central air conditioner was the best of its kind. After building the central air conditioner, I moved on to the furnace. I wasn’t sure which furnace I wanted to use, so I decided I would start out by trying a gas furnace. I personally love gas furnaces more than any of the other furnaces. After building the gas furnace and attaching it to the central air conditioner, I developed a two part air purification system. I put a HEPA air purifier and a UV light air purifier in this HVAC unit, so that the air had to flow through both of the air purifiers. I finished it with a smart thermostat.
