HERS Rater Refrigerant Charge test

 

How the Refrigerant Charge Measurement verification works:

When a new A/C system is installed, the installing contractor performs the refrigerant charge measurement and has an independent, third party HERS rater verify.  This applies when either replacing an existing HVAC unit or installing a new system.  The contractor then fills out the appropriate sections of the standard CF-6R form indicating the proper amount of refrigerant charge.  The HERS rater then verifies the refrigerant charge using one of two possible methods.  The first, called an intrusive method, involves the HERS rater attaching their own gauges to the system to measure the refrigerant charge.  This does not set well with many HVAC contractors.  Because of this another approach may be used, this is referred to as a “non-intrusive” method.  This method requires the HVAC installer to install temperature measurement access holes and saturation temperature measurement sensors.  This allows the HERS rater to verify the system performance and refrigerant charge without attaching gauges to the system.
