I can do just as good
I may sound like I am full of myself here, but I know a lot about heating and air conditioning repair! And I never went to any kind of HVAC school for it.
I do not have any kind of heat or a/c certification, but I feel I can repair a central heating and air conditioning system within reason just as good as an HVAC professional can! I have done it! How I managed to do all of this was from watching a lot of videos on heating and air conditioning repair as well as reading a lot of books on the subject.
Then I would try different things through trial and error as I learned. You can call it self teaching heating and cooling school in a way. I even believe I could become an independent heating and air conditioning contractor! But without a certification I could not do it legally. Because of this I have actually been thinking about taking night classes at an HVAC school and just go through the motions to get my heating and air conditioning certification. I know I would pass the class with flying colors for sure! I actually am going to look into this in the new year. Sure I have a job right now, but it is not what I want to be doing. I feel my true calling in life is to become a certified heating and air conditioning professional! I will accomplish this for sure with no doubt in my mind! After January I will be doing this.
