Keep Refrigerant in Air Conditioners and Heat Pumps Fully Charged
The refrigerant charge is benefited by the variable motor speed because keeps the refrigerant operating correctly. The refrigerant is important because it helps to operate the air conditioning unit. The function of the refrigerant is to move heat from outside to the inside of the home. It removes heat and provides cooling to the compressor. It also lubricates the compressor with oil. If anything was to happen to the refrigerant, a technician would have to provide troubleshooting and repair. The labor time for this is approximately 1 hour.
The refrigerant charge is often the source of many issues that arise with air conditioners. The purpose of the refrigerant charge is to keep the coils inside the unit from freezing. The coils pulls condensation from the air and is best when operating at the dew point level. If it operates at or below freezing, it will freeze the evaporator coil. If the coils do freeze, this will result in the output of little or no cooling by the air conditioner.
This result happens because there is a low level of refrigerant inside the unit. However, too much refrigerant will reduce efficiency and it will raise the head pressure. To ensure the right amount of refrigerant exists in the unit, the line leaving the condenser should be inspected and ensured that it is not frozen but full of liquid refrigerant.
