A/C unit works intermittently
Hello.....our AC unit is less than three years old (new house) and it has stopped kicking on in the late afternoon/evening for the past few days. I first noticed it a couple of days ago around 6 pm and it was showing 78 degrees in the house. We have it set to 72 degrees and it was not running at all and not sure how long it had been off. It finally kicked on between 7-8. Again on Friday it was 76 in the house and not kicking on...we left for an event and it was back on by the time we got home around 9:30 pm. It is now Sunday and it has stopped kicking on again and it’s 78 degrees. Filter is fine, so not sure what else it could be. Any suggestions? Thank you!

You need to do some basic troubleshooting.....
On a call for cooling is the blower in the house coming on ?
On a call for cooling is the outside condeser coming on ?
Off the top of my head...... if the blower is working and the condenser is not.... you are low on refrigerant.

Another possibility that comes to mind is that you have an overflow safety switch.
If the furnace/air handler is in a location where leaking water could cause damage.... there would be a good chance you had a safety switch. After several hours the water could drain down allowing the system to run again.

AC Started Working but Now Leaking Water
So the AC came on around 9:45-10 I believe (couldn’t hear it from my room so unsure). When I went to check it, I could hear water dripping. Removed the filter and there is water coming from under the unit. Turned off the unit to keep the water from continuing to leak. It has already started to leak into my kids closet and soak the carpet.

Ok, it could be a condensate overflow. Or some other condensate protection device.
Is the evaporator frozen?

It's good you found it so soon. The problem is going to be a clogged drain line.
If you know where the line drains outside and you need a quick way to clean it..... connect a shop vac to the drain line outside and draw the water and crap thru. Be sure to remove the filter first from the vacuum.
