Again, you can only do this once you have made sure you got the right diagnosis. Otherwise, it will forfeit the entire purpose of refilling. Recharging a dehumidifier needs a specific refrigerant called R-22 (for older units and brands), and R-410A (for most modern dehumidifiers).More efficient. R32 has higher cooling efficiency, making it more energy efficient than R410A. More cost effective. Less R32 is required than R410A and it is easy to handle making refilling cost lower. R-32 can reduce electricity consumption by up to 10%. Better for the environment.

To determine the total cost of refilling the entire unit, multiply the number of pounds your unit requires by the price per pound. Additionally, you’ll need to pay the technician’s labor cost of repairing any refrigerant leaks. These costs can add up to be anywhere between $225 and $1000.This is a Step by Step Process (In Real-time) of Adding R-410A Refrigerant into a System that is a little Undercharged!
