What is the SEER2 rating of the GE Appliances ASH118PRDWA?

The GE Appliances ASH118PRDWA is rated at up to 21.0 SEER2 and 12.5 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the GE Appliances ASH118PRDWA 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 ASH118PRDWA cost to run per year?

At its rated efficiency it costs about $382-$1,109 a year in electricity in large U.S. cities, depending on climate and local rates - for example $483 in Phoenix and $936 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GE Appliances ASH118PRDWA the same as the Haier 1U18AP2VHA?

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 GE Appliances ASH118PRDWA?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses ASYW18PRDWB.

What refrigerant does the GE Appliances ASH118PRDWA 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.

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.
