What is the SEER2 rating of the Bryant GH5SAN542**AA?

The Bryant GH5SAN542**AA is rated at up to 15.5 SEER2 and 13.0 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 12 certified matchups SEER2 ranges from 15.2-15.5.

Is the Bryant GH5SAN542**AA 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 3.5-ton model.

How much does the Bryant GH5SAN542**AA cost to run per year?

At its rated efficiency it costs about $1,286-$3,312 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,568 in Phoenix and $2,753 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Bryant GH5SAN542**AA the same as the Heil H5H6S42*K*AAA?

Yes, as far as the certified ratings go. ENERGY STAR lists 3 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 Bryant GH5SAN542**AA?

ENERGY STAR lists 12 certified combinations for this outdoor unit. The highest-rated ones use FT5ANBD60L, FG5ANBD60L, PF5TNBD60L.

A good fit if…

You want a choice of indoor units - 12 certified pairings.

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 central heat pumps.
You mainly need heat - its HSPF2 is below average for central heat pumps.
Comfort and noise matter - a single-stage compressor runs only full-on or off.

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.
