My brother has been entirely working towards being a licensed Heating as well as A/C serviceman. In order to get his certification, he has to log in a particular amount of hours in the Heating as well as A/C industry. He needs to go on Heating as well as A/C repair jobs with an actual licensed supplier, then kind of like student teaching or an internship in the Heating as well as A/C world. After that, my brother will need to take a lot of tests to prove he has the heating as well as cooling proficiency to be in the field. Right now though, he has only logged in a few in field hours. My brother however feels he knows a lot about Heating as well as A/C repairs. Everytime I have him over to my home I cringe inside. I am praying every time that he does not touch my furnace or A/C unit. I am sure that by the time he is done with the program, he will suppose a lot. Right now though, he has a pressing ego as well as no proficiency. My brother has messed up my Heating as well as A/C epically quite a few times. He has taken apart my whole oil furnace as well as then put it back wrong. He has injured the fan blades on my cooling system. He also tried to clean my air duct as well as ended up making a hole in it. I hate to tell him to stay away from my Heating as well as A/C equipment. But, my brother is just not great enough to handle it yet. He does need practice, but I don’t want to pay for all the mistakes that he makes in my house. The sad space is that he really thinks he does a great job.
