Hi everyone, excited to be a new member.

I am a serice technician for an apartment complex and this week has brought high temperatures and high humidity and I have a problem.

I was checking the refrigerant charge on one of our air conditioners today, which is a 1.0 ton R-22 split system. I was using the charging chart supplied with the condensing unit and the indoor air temperature entering the evaporator was 85* F, but the chart only goes up to 76* F.

What would you do in this sort of situation?

Thanks!
