DIY Heating, Ventilation and A/C cleaning breaks system

I was learning online how your Heating, Ventilation and A/C system should be cleaned out and maintained once or twice a year.

I am kind of handy with a tool belt so I decided I should just do it myself. I watched lots of videos and study up on everything. Then I got to labor with my tools, a vacuum and some oil. I took my time and was genuinely careful but when I put everything back together, my Heating, Ventilation and A/C system simply would not turn on. I took it apart again and looked at all of the connection but everything was right. I knew I had to call in the professionals. This was over my head. A real Heating, Ventilation and A/C supplier came out the genuinely next day and the serviceman took one look at my Heating, Ventilation and A/C system, flipped a switch on the side, and said, “well here is your problem.” I felt so stupid. I had simply turned off my Heating, Ventilation and A/C system like you might turn off a light switch. The switch must have gotten bumped when I was moving things around. It might have even gotten caught on the cleaning rag or something. I did not even know there was an off switch! Other than that, the serviceman said I did a good job cleaning, for the most part. He gave me some hints and tips for next time but he also indicated that his supplier cleans Heating, Ventilation and A/C systems for genuinely little currency. It sounded like a good deal but I kind of just want to do it myself. How else will I ever learn?
