    That would be interesting trying to get the indoor blowers to run at the same speed. You would need to add a relay system.

    How many times must one fix something before it is fixed?

    Thanks for all the input. We already use nitrogen and a micron gauge. We have not installed any yet, but have worked on several. They have left a bad taste. One had leaks in the accumulator. The same repair on a R-22 system would have cost the customer less money, which means we would have made less money. Maybe I need to start using now instead of waiting till I am forced to use.
