Wouldn't it be the same BTU hours? Seems like the new system might
even cool better, cause it's all new clean equipment.

The old 10-SEER condenser had a larger compressor BTUH capacity in
relationship to the cooling coil than does the 13-SEER.
Therefore, with the 13-SEER matched system the coil temps will not be
quite as cold at the same airflow rates through it.

If you ran the unit at night when the air temp was too cold the
evaporator will drop below the freezing point & it will freeze over.
If that was not the cause then it could be leaking down yet, or there
might be several other problems.

If the rooms furthermost from the blower are much warmer, then you
have
an airflow & probable ductwork problem.
The system may have numerous things NOT functioning properly that need
to be revealed using effective troubleshooting techniques, & then
fixed!
Well, you might want to give the so-called tech some hard copies of
some
of my pages.
That may or may not help him, some simply refuse to or cannot learn.
It is your decision, however, I would not let him near the system
again!
Read & learn! - udarrell
