What is the SEER2 rating of the MOOVAIR DMA18HOS25230E8?

The MOOVAIR DMA18HOS25230E8 is rated at up to 23.5 SEER2 and 12.5 EER2 for cooling and up to 10.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 3 certified matchups SEER2 ranges from 20.0-23.5.

Is the MOOVAIR DMA18HOS25230E8 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 18,000 BTU model.

How much does the MOOVAIR DMA18HOS25230E8 cost to run per year?

At its rated efficiency it costs about $342-$1,072 a year in electricity in large U.S. cities, depending on climate and local rates - for example $444 in Phoenix and $913 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the MOOVAIR DMA18HOS25230E8 the same as the Kepler ODUMOX430-18HFN1-MU0W?

Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the MOOVAIR DMA18HOS25230E8?

ENERGY STAR lists 3 certified combinations for this outdoor unit. The highest-rated ones use DMA18HIW25230E8, DUA18HICU230X5, DUA18HIDU230X5.

What refrigerant does the MOOVAIR DMA18HOS25230E8 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.

18,000 BTU mini-split heat pump · DM-series

MOOVAIR DMA18HOS25230E8

Very good cooling and heating efficiency for a 18,000 BTU mini-split heat pump, but not rated for cold climates.

Ranks #121 of 465 18,000 BTU mini-splits for cooling efficiency, and costs about $433 a year to run in a mixed climate like Atlanta.

A good fit if…

You want low cooling bills - its SEER2 beats 70% of mini-splits.
It will heat most of the year - its HSPF2 beats 71% of mini-splits.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You want the newest refrigerant - it uses R-410A, which is being phased down.
