What is the SEER2 rating of the Concord 4DHPS209S-1P?

The Concord 4DHPS209S-1P is rated at up to 26.5 SEER2 and 15.8 EER2 for cooling and up to 13.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 52 certified matchups SEER2 ranges from 19.2-26.5.

Is the Concord 4DHPS209S-1P good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,000 BTU/h at 5°F with a COP of 2.17, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the Concord 4DHPS209S-1P cost to run per year?

At its rated efficiency it costs about $160-$457 a year in electricity in large U.S. cities, depending on climate and local rates - for example $201 in Phoenix and $385 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 4DHPS209S-1P?

ENERGY STAR lists 52 certified combinations for this outdoor unit. The highest-rated ones use CONCORD DWM206S4-1P, Armstrong Air DWM206S4-1P, DUCANE DWM206S4-1P.

What refrigerant does the Concord 4DHPS209S-1P 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.

9,000 BTU mini-split heat pump · 4DH SERIES

Concord 4DHPS209S-1P

Excellent cooling and heating efficiency for a 9,000 BTU mini-split heat pump, and certified for cold climates.

Ranks #94 of 395 9,000 BTU mini-splits for cooling efficiency, and costs about $188 a year to run in a mixed climate like Atlanta.

A good fit if…

You want low cooling bills - its SEER2 beats 93% of mini-splits.
Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 8,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 97% of mini-splits.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

You want the newest refrigerant - it uses R-410A, which is being phased down.
