ok here is the answer early

they had to wait till the outside ambient air got down below 98 with the extreme indoor temp. plus they were not smart enough to take cold water from an outside faucet to keep the head pressure down. Hey this really happened to a very large service company whose name I wont mention.HEY GUYS, IF YOU EVEER GET IN A POSITION WITH EXTREEM HIGH OUTDOOR TEMPS OF 95 DEGREES AND ABOVE ANND IDOORS TEMPS OF ABOVE 86 AND THEY UNIT JUST WILL NOT RUN LOOK AT YOUR PRESSURE CHART. THE HIGH LIMIT WILL KEEP YOU LOCKED OUT.



PEACE BE WITH YOU

    I thought I put that in my

    answer Dave, 410a is not high ambient friendly.... If its super hot out, I spray them all down no matter what gas they use.. We don't see triple digits often, but changing coil conditions to affect pressures is day one stuff.... Its funny to watch the customers face while you hold there garbage can cover over their fan, it works both ways..
