What is the SEER2 rating of the GE Appliances ASH218JCDD?

The GE Appliances ASH218JCDD is rated at up to 21.0 SEER2 and 12.7 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the GE Appliances ASH218JCDD 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 GE Appliances ASH218JCDD cost to run per year?

At its rated efficiency it costs about $406-$1,279 a year in electricity in large U.S. cities, depending on climate and local rates - for example $527 in Phoenix and $1,089 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GE Appliances ASH218JCDD the same as the Haier 2U18MS2HD?

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.

What refrigerant does the GE Appliances ASH218JCDD 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 · Multilink

GE Appliances ASH218JCDD

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

Ranks #331 of 465 18,000 BTU mini-splits for cooling efficiency, and costs about $516 a year to run in a mixed climate like Atlanta.

A good fit if…

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.
Cooling cost matters most - its SEER2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
