I need to figure out how to maintenance our central a/c

I easily need to figure out how I am going to maintenance our central a/c.

I know that I do not know much about central a/cs, but I am going to have to do something about our central a/c, or I am going to be in large trouble this summer.

I wish that I wasn’t struggling so much financially; Before I lost our task, I would have never upset about the central a/c, however whenever our oil furnace or our central a/c stopped toiling before, the only thing that I needed to do was to call an Heating & A/C serviceman to have them maintenance our Heating & A/C unit… However, now, I cannot afford to maintenance our central a/c. I just barely was able to afford to maintenance the oil furnace during winter, plus our new task does not pay as well, so I am not able to afford to do a lot. Instead, if I want to use our central a/c, I am going to have to learn how to maintenance our own central a/c. Honestly, I have no system how to even begin learning how to maintenance our own Heating & A/C unit, however fixing our own Heating & A/C machine was not something that I ever thought that I was going to have to learn how to do. I figured that it would be super easy to learn, but I was wrong, however sure, there are a lot of videos online that tell you how to maintenance your own central a/c, but I do not even have the slightest clue about what is wrong with our central a/c, and even if I did, I do not have the right tools to maintenance our central a/c, and do you know how strenuous it is to maintenance something with the wrong tools?
