What is the SEER2 rating of the Heil DLCSRBH18AAK?

The Heil DLCSRBH18AAK 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 201 certified matchups SEER2 ranges from 17.6-22.0.

Is the Heil DLCSRBH18AAK 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 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Heil DLCSRBH18AAK cost to run per year?

At its rated efficiency it costs about $364-$1,045 a year in electricity in large U.S. cities, depending on climate and local rates - for example $459 in Phoenix and $880 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 Heil DLCSRBH18AAK?

ENERGY STAR lists 201 certified combinations for this outdoor unit. The highest-rated ones use DAY & NIGHT DLFSHBH18XAK, COMFORTMAKER DLFSHBH18XAK, ARCOAIRE DLFSHBH18XAK.

What refrigerant does the Heil DLCSRBH18AAK 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.
