Instructions:

Review the methodology to make sure it aligns with your project's requirements.

All inputs are required for full results

1. Select the Known Efficiency Type that you want to convert from the dropdown menu.  Options Include:

   • COP​

   • EER

   • SEER

   • SEER2

   • HSPF

   • HSPF2

   • kW/Ton

2. Enter the Efficiency Value. For example, for 15 SEER equipment, enter "15".

3. Enter the Equipment Type.  This is required when converting to and from the DOE's Jan 1, 2023, HSPF2 and SEER2 energy ratings.

4. Click the Calculate buttons.  The results will appear in the table.

​

Methodology and Equations:

The following conversion equations are used in the calculator: 

​

EER = 0.875 x  SEER

EER = 12 / kW/Ton

COP = 3.516/ kW/Ton

COP = EER / 3.413

COP = 0.293 x HSPF

​

​Conversions between SEER2 and HSPF2 use RESNET's conversion factors which were created based on empirical data. The conversions are as follows:

​

                                                    SEER2               HSPF2

Single Package                      SEER x 0.96        HSPF x 0.84  

Single Split                             SEER x 0.95        HSPF x 0.85

Small Duct High Velocity      SEER x 1.00        HSPF x 0.85

Space Constrained                SEER x 0.99        HSPF x 0.85
