Yet another update.
In previous post, the one unit was low from a leak. Hired a local company to with the hope they could find the leak. That was a waste of time. They refilled it, couldn't find the leak and $700+ later was on my own again. Spent next few years occasionally topping system off. Purchased digital scale and tank of 410a back then. Since then acquired a nitrogen cylinder, 410a recovery pump and tanks.
When system went low again I charged it to 400psi and checked all flares hoping it was one of them, but not so lucky. Found one evaporator coil with oil sheen on it and drain pan. Fujitsu discontinued 410a parts but was able to get a crossover part.
Question: What's the groups thoughts about adding some oil with the new E-coil? I've read and heard from installers between 0-2 oz.
