My attempts to save money went wrong

I made a pretty big mistake the other week, and you see our central heating and air conditioner had broken down and I wanted to try to save cash on HVAC repair. I did this by going online to the internet and seeing a bunch of videos on assorted websites about how to repair a central heating and cooling system yourself without being a certified heat and air conditioner specialist. I guess this was a entirely dumb move, however what can I say? I like to save cash whenever I can in any way that I can! To make an entirely long story short, I ended up making our central heating and air conditioner a lot worse. In the end, I had to spend double in heating and air conditioner repair than what I would have spent had I just called the local heating plus air conditioner company from the start instead of trying to be the cheapo and save cash! There is nothing wrong with saving cash, but when it is related to something that only a true professional should be doing, you should never try to do it yourself! This can cause you more harm than good as it did in our case, so the moral to this story is never try to repair a central heating plus air conditioner when it breaks down. Spend a few hundred bucks plus call an HVAC professional. Otherwise, this could end up costing you thousands in the end if you make the damage far worse than what it is.
