    Stupid? Question about hoses

    My 410a gages have ball valve, but my 22 set is low loss. I like both.
    I too was under the impression that some kind of low loss hoses were required for service to lessen loss. Loosing all that...

    Restriction at the distributor would be my guess. Definitely a restriction though if it's freezing at that point.

    I have two sets, one for 22 and another for 410a. That way I know I won't mix refrigerants.

    Frosted Coil

    I'd say outdoor temp. Forty-five degrees outside is in no way a good indicator of cooling. If anything, your saturation temp was around 70 outside, so having such a low temp there would surely have...

    If the outdoor is also 2.5, you could run into problems just changing the AH. Too much refer in the evaporator. The EPR and HGBP would help mimic the proper BTU rating.

    I disagree. Like others, I say it helps the motor run efficiently and that it puts the electricity in better phase alignment in addition to the boost it provides to the motor.

    If the reversing valve is energized in cooling, you should get 24v from O to common or 0v from R to O. The AH provides the 24v for the outdoor unit to run after all.
