What is the SEER2 rating of the Arcoaire DLCMRBH36DAK?

The Arcoaire DLCMRBH36DAK is rated at up to 20.0 SEER2 and 11.0 EER2 for cooling and up to 9.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Arcoaire DLCMRBH36DAK good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 36,000 BTU model.

How much does the Arcoaire DLCMRBH36DAK cost to run per year?

At its rated efficiency it costs about $849-$2,487 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,077 in Phoenix and $2,101 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

What refrigerant does the Arcoaire DLCMRBH36DAK 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.

A good fit if…

You want steady temperatures and quiet running - the compressor varies its speed.
You want a choice of indoor units - 12 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for mini-splits.
You mainly need heat - its HSPF2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
