I l gained the hard way that there is nothing up-to-date under the sun, especially when it comes to Heating, Ventilation, plus A/C units. Every year, my town hosts an Heating, Ventilation, plus A/C building competition where some of the best Heating, Ventilation, plus A/C contractors plus heating plus cooling designers build their best air conditioning systems, gas furnaces, plus media air purification systems plus then display them to be voted on. Whoever has the most particular or just the best Heating, Ventilation, plus A/C device wins a large check. I was still a young Heating, Ventilation, plus A/C contractor, although I thought I knew all there was to recognize about basically any heating or cooling unit. I had worked as an Heating, Ventilation, plus A/C contractor for numerous years plus for three years I worked in a heating plus cooling business as well as an air conditioning system plus gas furnace warehouse. I decided to enter the contest, plus I had high hopes, then most of the Heating, Ventilation, plus A/C contractors would make some kind of central air conditioning system, electric gas furnace, or maybe even a UV light media air purification system. Some of the more advanced Heating, Ventilation, plus A/C contractors would build their own smart thermostat. I decided to build an Heating, Ventilation, plus A/C device never seen before in the heating plus cooling competition. I decided to build a SEER rating device that could be used not only on air conditioning systems, however also on gas oil furnaces of all types. This was no simple task as SEER rating devices are hard to build plus the technology is complicated. I went to work in my heating plus cooling shed I had built in my backyard. It took various weeks, although I finally finished my SEER rating device in time for the Heating, Ventilation, plus A/C competition. I won the competition, although my SEER rating device was listed with various other SEER rating devices similar to mine.
