What is the SEER2 rating of the Carrier 50NR-B60---30?

The Carrier 50NR-B60---30 is rated at up to 15.5 SEER2 and 11.5 EER2 for cooling and up to 7.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Carrier 50NR-B60---30 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 5-ton model.

How much does the Carrier 50NR-B60---30 cost to run per year?

At its rated efficiency it costs about $1,698-$4,550 a year in electricity in large U.S. cities, depending on climate and local rates - for example $2,095 in Phoenix and $3,803 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Carrier 50NR-B60---30 the same as the Bryant 605ENXB60000AA?

Yes, as far as the certified ratings go. ENERGY STAR lists 4 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.

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.
