The central air conditioner is blowing air but it's not cold air?

Check to make sure that the condenser (outside unit) is running. If it isn't, the fan in the air-handling unit (inside your home) is only recirculating the air inside your home Then make sure that the water pan under your inside unit is not full of water. If it is, suck it out with a wet-dry vac.

The floating cut-off switch that activates your air Compressor outside will re-activate and your compressor will start working again. Also be sure that the drain pipe on your inside unit is connected and is not clogged. Otherwise your water pan will keep filling up and it will continue to shut off your A/C Compressor This usually fixes this issue especially if your Unit is less than 10 years old.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
