What is the SEER2 rating of the Airquest DLCPRBH18AAK?

The Airquest DLCPRBH18AAK is rated at up to 26.3 SEER2 and 15.3 EER2 for cooling and up to 15.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Airquest DLCPRBH18AAK good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 24,000 BTU/h at 5°F with a COP of 2.89, so it is still 2.9 times as efficient as electric resistance heat at that temperature.

How much does the Airquest DLCPRBH18AAK cost to run per year?

At its rated efficiency it costs about $321-$824 a year in electricity in large U.S. cities, depending on climate and local rates - for example $391 in Phoenix and $684 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 Airquest DLCPRBH18AAK?

ENERGY STAR lists 16 certified combinations for this outdoor unit. The highest-rated ones use TEMPSTAR DLFPHBH18XAK, AIRQUEST DLFPHBH18XAK, SMART COMFORT DLFPHBH18XAK.

What refrigerant does the Airquest DLCPRBH18AAK 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.
