New central air conditioner stopped blowing cold air, help?

Sounds as if it is reaching the set temperature (check thermostat for accuracy) or it may be freezing up and having to defrost.

The thing is supposed to cycle,.... thats what it does. Especially if the set temperature is extremely close to the ambient temperature.... But know this: the front filter must be kept CLEAN. -and there is a small thermostatic bulb that tells the compressor when its cool enough.... If that small bulb touches the evaporator coil, it will cause the unit to short cycle.

-because the cold coil tells the thermostat its cool enough...

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.
