Just Changed A Component

Which Component was changed? Just click on the link to find out what is required.                                                                                          Return to Compliance Certificates

The Package Unit (usually located on the Roof)              

The Condenser (in a split system that is the unit that is most often outside)    

The Furnace / Air Handler (located in the attic, in a closet in the house or on a platform in the garage)   

The Cooling Coil (located at the Furnace / Air Handler)    


Below you will see reference to 'Rated Fan Flow'. This number is determined by one of two methods.
1. The ton rating of the condensing unit. i.e. 3 Ton. The formula is then ((ton*400)=*allowed leak rate) example--((3*400)*.15)=180 CFM
2. The Output BTU of the furnace example-- ((64000 * 21.7) * .15) / 1000=208 CFM
You changed your Package Unit and you are located in Climate Zones 2 or 9 thru 16. All you need is a Duct Sealing Test.
If you kept your existing ducts or you did not add more than 40' of new ducts in unconditioned space then the ducts must pass with a target duct leakage less than 15% of rated fan flow.
If you change your ducts or added more than 40' of new ducts in unconditioned space then the ducts must pass with a target duct leakage less than 6% of rated fan flow.

You changed only your Condenser and you are located in Climate Zones 2 or 8 thru 15.You will need a Refrigerant Charge and Airflow Test (RCA) and a Duct Sealing Test. The ducts must pass with a target duct leakage less than 15% of rated fan flow.

You changed only your Furnace / Air Handler and you are located in Climate Zones 2 or 8 thru 16. Now if you do not have an Air Conditioner and the system is 'Heat Only' which is common in Climate Zone 16, all you need is a Duct Sealing Test.


But if there is Air Conditioning at your project you will need a Refrigerant Charge and Airflow Test (RCA) and a Duct Sealing Test. The ducts must pass with a target duct leakage less than 15% of rated fan flow.

In all of the above component changes, if you added or replaced more than 40' of ducts in unconditioned area at the same time you changed components the Duct Sealing test will need to pass with a target duct leakage less than 6% of rated fan flow.

If it is any of the above that has been done we can get that project registered and the testing done to complete the project. Contact us at 760-646-2589 or 760-530-0712. Let's get the project finished and the paperwork done.
