What is the SEER2 rating of the Cooper&Hunter CH-HPR18-230VO?

The Cooper&Hunter CH-HPR18-230VO is rated at up to 22.0 SEER2 and 13.0 EER2 for cooling and up to 11.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 26 certified matchups SEER2 ranges from 17.6-22.0.

Is the Cooper&Hunter CH-HPR18-230VO good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,000 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the Cooper&Hunter CH-HPR18-230VO cost to run per year?

At its rated efficiency it costs about $364-$999 a year in electricity in large U.S. cities, depending on climate and local rates - for example $452 in Phoenix and $838 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 Cooper&Hunter CH-HPR18-230VO?

ENERGY STAR lists 26 certified combinations for this outdoor unit. The highest-rated ones use CH-B18MOLVWM-230VI, CH-18MOLVWM-230VI, C&H CH-B18MOLVWM-230VI.

What refrigerant does the Cooper&Hunter CH-HPR18-230VO use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.
