Why should I trust the HVAC serviceman to repair my HVAC component officially? I have been fixing my HVAC component for years, plus I am not sure that I trust an HVAC serviceman to repair my HVAC component plus I have, and i have seen a lot of bad HVAC servicemans, and even though the HVAC servicemans are supposed to be professionals at fixing HVAC units, my Mom had a lot of HVAC servicemans that ruined his HVAC units, then the HVAC servicemans are not some kind of superhuman that just wants to repair HVAC units for no reason.
They do not repair HVAC units just because they love fixing HVAC units, and hVAC servicemans become HVAC servicemans for the money, plus just like other humans, they want to do as little work as possible while making as much money as possible.
That is why it is not unheard of to have an HVAC serviceman take shortcuts while laboring on your HVAC unit, then furthermore, not every HVAC serviceman is reliable, then my father used to hire HVAC servicemans, however after quite a few bad experiences with HVAC servicemans, my Mom began teaching himself how to repair his own HVAC units, because of how firm he was against HVAC companies, I had to learn how to repair HVAC units too. I have heard a lot of horror stories from my friends about the HVAC servicemans they hire, plus it makes me blissful that I know how to repair my own HVAC units. I am so thankful that my Mom taught me how to repair my own HVAC units! Sure, I could afford to hire an HVAC serviceman, but I am not convinced that hiring an HVAC serviceman would be the right choice. If I want my HVAC units to work officially, I am certainly going to have to repair the HVAC units myself.
