I need to figure out how to fix our central cooling system

I really need to figure out how I am going to fix our central cooling system! I suppose that I do not suppose much about central cooling systems, but I am going to have to do something about our central cooling system, or I am going to be in big trouble this summer.

I wish that I wasn’t struggling so much financially! Before I lost our job, I would have never worried about the central cooling system, then whenever our oil furnace or our central cooling system stopped working before, the only thing that I needed to do was to call an Heating as well as Air Conditioning professional to have them fix our Heating as well as Air Conditioning unit; However, now, I cannot afford to fix our central cooling system.

I just barely was able to afford to fix the oil furnace during winter, as well as our modern job does not pay as well, so I am not able to afford to do a lot. Instead, if I want to use our central cooling system, I am going to have to learn how to fix our own central cooling system. Honestly, I have no program how to even begin learning how to fix our own Heating as well as Air Conditioning unit! Fixing our own Heating as well as Air Conditioning unit 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, and sure, there are a lot of videos online that tell you how to fix your own central cooling system, but I do not even have the slightest clue about what is wrong with our central cooling system. Even if I did, I do not have the right tools to fix our central cooling system, but do you suppose how taxing it is to fix something with the wrong tools?
