thanks for the words of wisdom. yep, the book says the condenser is
charged for evap coil and 15 feet of line. the tech added 1.5 lb of
R410a. runs good.

I had a new carrier A/C 2.5 ton installed last Oct 07 after the
cooling season. The installer didnot add any refrigerant other than
what was pre charged in the condenser. He installed about 30 feet of
line and new evap coil (neither was pre-charged).

They need something like a minimum of 80 F to properly charge/tune a
new system. It was too cool last Oct?

Turned system on
this spring and it didnt seem just right. Service tech came today and
added 1.5 lbs of R410A. Do you think they should have added refrig
last Oct or do I have a leak.

Likely neither.

It only ran at most 2 weeks since it
was installed. Thanks

Consider the following:

a.) It was too cool to fully charge last Oct.
b.) The tech added the correct amount of R410A when requested and system
was fully testable.

If you've got the full documentation for the outside unit, it should
tell you what the pre-charge was. Add 1.5 lbs and see if it is not
very close to the R410A charge indicated on the spec plate. If so, *and*
it is cooling properly, you should be OK, so far as I can tell from here.
