Knowing the exact amount of refrigerant that is added to a system is crucial in getting a job done right.
What is a HVAC Refrigerant Scale?
An HVAC refrigerant scale measures the amount of refrigerant that has gone into a system by weight.
Since all HVAC systems need a set amount of refrigerant to work measuring the correct amount is very important.
Too little or too much and the unit will not work correctly.
Every system has the amount of refrigerant needed labeled on the unit or in a manual.
