    I would think that a retired chiller tech who's been a member of this board since '08 would be a pro member by now, not a regular guest. So I'm inclined to agree with you snupy.

    Just musing randomly, but breaking common would still have power passing through all components prior to returning to the furnace/ahu. So possible damage to those components without a complete...

    A 90+% gas furnace would make condensate. ;)

    I'd break Y as well unless the stat was digital and was hard wired with no batteries. People might notice a blank screen faster than no cooling. ;)

    Did you check all the safety limits? There may be one on the blower that's open, causing the problem. You said the furnace lights though? Only a two year tech here. ;)

    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.

    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...
