I am a true believer that most people can accomplish any task if they put their minds to it.
I don’t think that anyone is more qualified than anyone else, so long as adequate instruction is provided with explicit safety standards.
That’s why I refuse to pay for a professional to come and take care of my home’s HVAC system. I am convinced that i can do the job just as good as they can, assuming I have my ipad right next to me. That way I can stream YouTube tutorials on any topic as I attempt to diagnose and repair my heating and cooling system. So far I’ve had good luck with this DIY ventilation maintenance and repair, but there’s always another task that needs to be accomplished. That means there are always more educational videos for me to watch, and new air temperature control mechanic skills to acquire. I’ve done well performing routine diagnostics, replacing the old HEPA air filters, and oiling up some sticky moving parts. After that, my most recent project was to examine the air ducts that run through the entire house. I read that having dirty or damaged ductwork can greatly affect the efficacy of your home HVAC system. After that, I decided I would climb up and clean the ducts out all on my own, using our normal vacuum cleaner. Well, that project sure didn’t go as smooth as possible. Long story short, I’ve recently had to hire a professional ventilation expert to reinstall a section of ductwork and a local vacuum repairman to boot.
