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.
