Not being a Lennox dealer, I would like to know if the 10ACB60/-11P
condensor is an entry level unit? The Serial starts with 5801E****...making
it an 2001. This condensor runs really high head with a 22° TD....the
condensor coil is really small. When I first walked up to it, I would have
sworn that is was a 3-ton.

What's the suction pressure & superheat, the discharge pressure &
subcooling, and the refrigerant. Then maybe someone could tell ya you
should clean the condenser coil.

After you cleaned it did you wave your hand over the top to check the
air flow?

It should be blowing pretty much straight up evenly spread across the
blade opening.

If the air feels like it blowing out from around the outer edges then
the coil is still dirty.

Is it possible this lennox is like many others and the condenser is a
slab coil. Two slab coils in fact. If so you need to disassemble the
condinsing unit and seperate the coil halfs. Then wash them again.
Use that Nu-Calgon Nu-Brite coil cleaner. Wear gloves and saftey
glasses. Then re-check the air flow for improvement.

If a dirty coil isnt the problem Id look at an overcharge. I feel
silly as hell typing out basic shit like this. But fuck it, ill do it
anyway. :)

Do you feel as silly asking after all the years youve been a tech? I
mean what can possibly be so hard about figuring out a high head
pressure problem.

You said you had a 22 TD across a coil but you didnt say which one.

What does the grade of equipment have to do with a system problem
anyway?
