It is normal to check the charge.
As for removing refrigerant, depends if its a fixed metering device, and the air flow is lowered too much, and was already low.
It is normal to check the charge.Hi, I just had some work done to reduce humidity in my home, and the tech lowered the blower speed (under the house) on the hvac unit, and also took some refrigerant out of the outside unit.
Is it normal to reclaim refrigerant when just changing the speed ?
