A/C stops cooling yet the compressor fan outside continues to run as if all is OK.
Here's what's been done so far:
New Capacitor
New Contactor
New Fan motor
Condensate drain is clear and drain switch tests OK.
Refrigerant is fine
Problem is, every time the repair guy comes out it is working again. It stops cooling usually for a couple hours at random times. Sometimes it can go for 2 weeks without issue then it happens again.
It's an 8+yr old Carrier unit that was part of the original construction (I'm 2nd owner). When it is working it cools perfectly so it isn't a refrigerant issue.

There is a home show on 96.5 FM 7am sunday morning.
You might try calling them. Of course have all the info you can available. Unit serial number, a list of what has been checked, replaced etc.
In your posts you have said you are considering replacing the unit. Ours is three years old installed by the builder.
Ours is 13 SEER-it is posted on the unit and I think that was the minimum that they could install at the time.
I did notice that at Fenny they are using 15 SEER. The difference is 13%. Would you save 13% in your heating and cooling costs? That might be an interesting question to ask.
As you well know an intermittent problem is the most difficult one to find.
