Would be nice to be HVAC certified so I don’t have to pay the professionals so much

I get it, it’s about keeping the environment safe

When I came home from work the other day, the house was a little bit overheated. I went to the HVAC vents to see if they were putting out cold air. Sadly, the air was lukewarm and I knew something was going on with the HVAC system. I checked around and then went outside to the A/C condenser unit. When I was looking at the connections, that’s when I noticed there was a refrigerant leak in the line. I knew since there was a leak, all of that refrigerant was probably empty and my cooling system was not able to perform as it should. I called the HVAC company right away and soon enough I was there speaking with the HVAC professional. He was able to repair the leak and then he got to work refilling refrigerant to my cooling system. I was really thankful to have frosty air in my home again, but it was kind of expensive to get that taken care of. I honestly wish I could do a repair like that on my own so I don’t have to pay these HVAC professionals so much money. Unfortunately, they say that only the professionals are permitted to handle refrigerants because you really have to know what you’re doing. I get it, it’s about keeping the environment safe. You don’t want to spill a bunch of refrigerant all over the place. I suppose I could go to night school or something and get my HVAC certification, but I’m not sure if I would want to do this work for a living.
