What kind of coolant should I buy for our AC tech?

My a/c device has been as cool as I thought it should, the last couple of weeks.

I considered trying to call the Heating and A/C supplier but I think how much it costs to just have them come into the house.

I’m thinking that all I need to do is call the Heating and A/C supplier and find out what kind of coolant I need to put into our AC unit. I’m sure that if I could get the right coolant, I could figure out how to put the coolant in and then I would end up without any complication with the air conditioning system. I finally went online, hoping to find some information. I couldn’t think how various websites there were that pertained to a/c. There must have been thoUSnds and every a single of the websites gave some information that matched the others and yet it gave information that was completely different. I was shocked to not only find all of this information, but to not be able to remember which website was which. I ended up closing out our computer when our eyup became orange and itchy from staring at the screen. I looked at our watch and realized I had wasted various sparse minutes while trying to find information. All I certainly found out was that a layman could not buy the coolant that is made to go into an a/c unit. I finally called the Heating and A/C supplier and asked them to come out and look at our a/c unit. I was right and all I needed was to have our coolant refilled.
