Hello, My home has a Payne 018-060-PA10 air conditioner unit, which does not keep my house very cool. It is big enough for the house. The problem is that the air which comes out of the vents is just not very cold. I have been told that my system may need a recharge. I have already checked and changed the air filter on the blower. The unit is only 2 or 3 years old, and I've hardly used it, so I am assuming that it needs a charge. So, here's the deal. I want to recharge it myself. I don't know anything specifically about air conditioners, but I am an engineer and I have lots of tools and instruments. Can someone please explain to me a general synopsis of what I need to know in order to recharge my AC.
thanks, Andy
