There is a reason that HVAC professionals go to all those lengths to be certified and licensed for what they do.
I have the price tag to prove it. Going forward with a stupid idea of fixing my own HVAC went so terribly wrong that I can hardly believe I thought it was ever a good idea. It all started when I noticed that the HVAC was cycling on a whole lot. It was still early summer so the temps weren’t exactly broiling yet. But the HVAC was running all the time. I felt the air coming out of the vents and it wasn’t near as cool as it normally is. This is the spot I should have reached for the phone and called the HVAC professionals that we have used for decades. That is not what happened. Instead, I went to the computer and looked up a diagnosis online. What could go wrong? It appeared to me that all I had to do was go to the hardware store and get an HVAC recharge kit. They wouldn’t make them if I couldn’t use them right? Of course, I didn’t know what I was doing nor did I even really know what sort of problem the HVAC was having. But that didn’t stop me from hooking up the recharge thing. It didn’t take but a few minutes before I heard a pop and then a hiss. This wasn’t good. At least I had the wherewithal to turn off the HVAC and call the HVAC people. I had cracked the compressor and done some other damage that was totally unrelated to the initial problem. Please, learn from my mistake. Only have the pros fool around with the HVAC.
