    I bet the company working on the system with R410A had a heck of a time charging their unit. Maybe they installed a second compressor as well?

    House "A" had a service contract and paid a flat fee. House "B" called someone from the yellow pages, and paid time and materials?

    Oh c'mon

    no AC talk yet, its still 30 at night over here... 410a doesn't like high ambients, but recovering, then holding, then flushing the system, and changing the txv, compressor, ect , then nitrogen testing, then vacc-ing it down, then charging it, it takes a lot of time... I have done my share, none of them are fun, although we dont normally get 115* ambients around here... maybe 98* but not very often... I can count on one hand how many triple digit days we have had in my memory..

    Moisture. It's harder to pull moisture out of a 410a system. If left open to long it is harder to get down to an acceptable micron reading.
