What is the SEER2 rating of the GE Appliances 1G12CB2BE?

The GE Appliances 1G12CB2BE is rated at up to 21.0 SEER2 and 12.0 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 1G12CB2BE good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 10,400 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 1G12CB2BE cost to run per year?

At its rated efficiency it costs about $266-$834 a year in electricity in large U.S. cities, depending on climate and local rates - for example $345 in Phoenix and $710 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the GE Appliances 1G12CB2BE the same as the Haier 1Q12TE2BE?

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 1G12CB2BE?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses GS12WB2BE.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
