What is the SEER2 rating of the ECOER EODA19H-2436AA?

The ECOER EODA19H-2436AA is rated at up to 20.5 SEER2 and 13.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 35 certified matchups SEER2 ranges from 15.2-20.5.

Is the ECOER EODA19H-2436AA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 25,200 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the ECOER EODA19H-2436AA cost to run per year?

At its rated efficiency it costs about $670-$2,146 a year in electricity in large U.S. cities, depending on climate and local rates - for example $875 in Phoenix and $1,831 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the ECOER EODA19H-2436AA the same as the YISO YOHA2-36AA?

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 ECOER EODA19H-2436AA?

ENERGY STAR lists 35 certified combinations for this outdoor unit. The highest-rated ones use EAHATN-24BA, EAHDEN-24AB, EAHATN-36BA.

What refrigerant does the ECOER EODA19H-2436AA 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 low cooling bills - its SEER2 beats 96% of central heat pumps.
Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 25,200 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
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.

Questions6

What is the SEER2 rating of the ECOER EODA19H-2436AA?: The ECOER EODA19H-2436AA is rated at up to 20.5 SEER2 and 13.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 35 certified matchups SEER2 ranges from 15.2-20.5.
Is the ECOER EODA19H-2436AA good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 25,200 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
How much does the ECOER EODA19H-2436AA cost to run per year?: At its rated efficiency it costs about $670-$2,146 a year in electricity in large U.S. cities, depending on climate and local rates - for example $875 in Phoenix and $1,831 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the ECOER EODA19H-2436AA the same as the YISO YOHA2-36AA?: 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 ECOER EODA19H-2436AA?: ENERGY STAR lists 35 certified combinations for this outdoor unit. The highest-rated ones use EAHATN-24BA, EAHDEN-24AB, EAHATN-36BA.
