What is the SEER2 rating of the GE Appliances ASH118URDE?

The GE Appliances ASH118URDE is rated at up to 23.0 SEER2 and 13.0 EER2 for cooling and up to 12.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the GE Appliances ASH118URDE good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,000 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the GE Appliances ASH118URDE cost to run per year?

At its rated efficiency it costs about $365-$1,037 a year in electricity in large U.S. cities, depending on climate and local rates - for example $458 in Phoenix and $873 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GE Appliances ASH118URDE the same as the Haier 1U18EH2HE?

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 ASH118URDE?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses ASYW18URDE.

What refrigerant does the GE Appliances ASH118URDE 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.
