Carrier 38/40GXQ with 49' line : factory charge is ok or extra refrigerant?
Hi there,
I bought a Carrier 38/40gxq. (With 1/4 & 1/2 refrigerant line)
When the company installed it they said that the factory charge was enough to supply up to 65' of line. (I've got 49' line lenght here)
But i checked on carrier website the installation manual for this unit
(http://dms.hvacpartners.com/docs/100...8-40gx-5si.pdf) and found that they say something else!
If you look page 9 they say that the factory charge is good for 25ft, after that lenght you have to add 0.1oz of refrigerant per extra foot of piping...
It make 2 days that the unit seem to work fine. I tested the heat mode and it seem to work well too...
So this is ok??
Thanks ahead of time for your response!

So from what you think with 49' of line, extra refrigerant is needed as the installation manual say??
