Fuga y Cargando Refrigerante a un Aire Acondicionado en Invierno

Here I encountered a leak on the evaporator side of a central air conditioning unit. It was enough to warrant the customer having to recharge it periodically, but these days with R22, recharging is expensive. The correct approach is always to check for the leak and then proceed with the recharge. I did this in the middle of winter, which isn't ideal for recharging an air conditioner, but there are ways to do it.
