What is the SEER2 rating of the Arcoaire DLCSRBH09AAK?

The Arcoaire DLCSRBH09AAK is rated at up to 28.1 SEER2 and 16.2 EER2 for cooling and up to 12.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 99 certified matchups SEER2 ranges from 20.2-28.1.

Is the Arcoaire DLCSRBH09AAK good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 11,000 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 Arcoaire DLCSRBH09AAK cost to run per year?

At its rated efficiency it costs about $152-$526 a year in electricity in large U.S. cities, depending on climate and local rates - for example $204 in Phoenix and $452 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 Arcoaire DLCSRBH09AAK?

ENERGY STAR lists 99 certified combinations for this outdoor unit. The highest-rated ones use COMFORTMAKER DLFSHCH09XAK, ARCOAIRE DLFSHCH09XAK, AIRQUEST DLFSHCH09XAK.

What refrigerant does the Arcoaire DLCSRBH09AAK 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.
