Have you ever recharged your mini split AC/heatpump?

[kpoinville]

I installed an Acekool 9000 BTU mini split AC/heatpump on my 7x16 v-nose CTC camper last year. I recently repositioned the outside unit from the tongue nose to one of the v walls. Unfurtunately, I lost some of the refrigerant in the process and now find myself in need of a recharge. How have you found an HVAC tech that is willing to perform this task? Will an RV dealer do it? If so, what should I expect the cost to be for such a small unit?
