What is the SEER2 rating of the Concord 7SCP18V36P-**A?

The Concord 7SCP18V36P-**A is rated at up to 18.7 SEER2 and 11.0 EER2 for cooling and up to 9.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 582 certified matchups SEER2 ranges from 15.2-18.7.

Is the Concord 7SCP18V36P-**A good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 30,800 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the Concord 7SCP18V36P-**A cost to run per year?

At its rated efficiency it costs about $860-$2,334 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,065 in Phoenix and $1,954 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Concord 7SCP18V36P-**A?

ENERGY STAR lists 582 certified combinations for this outdoor unit. The highest-rated ones use 7EH36CX-**+TDR, 7E[C,U]36BX-**+TDR, 7EH30AX-**+TDR.

Questions5

What is the SEER2 rating of the Concord 7SCP18V36P-**A?: The Concord 7SCP18V36P-**A is rated at up to 18.7 SEER2 and 11.0 EER2 for cooling and up to 9.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 582 certified matchups SEER2 ranges from 15.2-18.7.
Is the Concord 7SCP18V36P-**A good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 30,800 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
How much does the Concord 7SCP18V36P-**A cost to run per year?: At its rated efficiency it costs about $860-$2,334 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,065 in Phoenix and $1,954 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Which indoor units work with the Concord 7SCP18V36P-**A?: ENERGY STAR lists 582 certified combinations for this outdoor unit. The highest-rated ones use 7EH36CX-**+TDR, 7E[C,U]36BX-**+TDR, 7EH30AX-**+TDR.
What refrigerant does the Concord 7SCP18V36P-**A use?: It uses R-454B.
