Form: Existing CF3R-MCH-26
When the A/C system equipment efficiency specified in the compliance model exceeds the prescriptive minimums, the High EER/SEER verification will be triggered. If triggered, the installed A/C equipment efficiency must exceed the values claimed on the CF1R as documented from an applicable certificate from one of the approved databases.

Note: In many projects the EER verification is inadvertently triggered due to an issue with the CEC’s report generator. The issue is caused because of the split in federally mandated efficiencies based on system capacity. Rather than differentiate based on system capacity, the compliance software defaults the ‘standard’ case to the minimum EER value of 11.7. Modeling an EER value of 12.2, which is the applicable code minimum for most projects, will trigger the EER verification.
Unless you intend to trigger the EER verification, the compliance model should use a value of 11.7 regardless of the applicable code minimum. Since the compliance software considers the ‘standard’ case to be based on an EER value of 11.7 there will be no effect on the resulting compliance margin. Regardless of the modeling work-around, the installed equipment must meet or exceed the Federal minimums which for equipment ≤45KBTUh is an EER value of 12.2.
The procedure shall consist of visual verification of installation of the following system equipment components and confirmation that the installed equipment is rated to achieve the required HSPF, SEER or EER rating:
(a) The manufacturer name and the model number of the outdoor unit or package unit.
(b) The manufacturer name and the model number of the inside coil if applicable.
(c) The name of the product directory used to certify the system performance.
(d) The certification number of the installed system if certification numbers for listed products are published by the product directory.
(e) The HSPF, SEER or EER value published by the product directory.
(f) The manufacturer name and the model of the furnace or air handler when a specific furnace or air handler is necessary to achieve the SEER, or EER rating.
(g) The specified metering device when a specific refrigerant metering device (such as a TXV or an EXV) is necessary to achieve the high efficiency rating.
(h) When a system rating specification includes a time delay relay, the installation of the time delay relay shall be verified according to the procedure in Section RA3.4.3.
