What is the SEER2 rating of the GE Appliances 1G12ED2BE?

The GE Appliances 1G12ED2BE is rated at up to 25.0 SEER2 and 12.5 EER2 for cooling and up to 11.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 19.8-25.0.

Is the GE Appliances 1G12ED2BE good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 14,500 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.

How much does the GE Appliances 1G12ED2BE cost to run per year?

At its rated efficiency it costs about $227-$700 a year in electricity in large U.S. cities, depending on climate and local rates - for example $293 in Phoenix and $595 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GE Appliances 1G12ED2BE the same as the Haier 1Q12RT2BE?

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 1G12ED2BE?

ENERGY STAR lists 5 certified combinations for this outdoor unit. The highest-rated ones use GS12WP2BE, US12AB2BE, US12CB2BE.
