Carrier 2.5 Ton Unit Replaced 2001 Compressor to new 2012. Freon 22.
Please I need help on system re-charge, this is my first compressor replacement job. I did recovered 4lb, 8oz, before removing compressor, after completing replacement of compressor & vaccumed. I charge the froen from recover cylinder. But there is still gas left in cylinder which cannot recharge due to pressure equal. Before I charge new freon22 I want make sure I am not over charging. Since guages are showing me Lowside 70PSI Highside 225PSI pressures look like to me high atleast lowside but temps are not right in evaprator. Should I go ahead charge more freon which will bring down Lowside PSI & Temp. I am sure I did not put all freon I removed system plate says 4lb 3oz but I have charged about 3lb.
