What is the SEER2 rating of the Bryant GH5SAN536**AA?

The Bryant GH5SAN536**AA is rated at up to 16.0 SEER2 and 13.0 EER2 for cooling and up to 8.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 63 certified matchups SEER2 ranges from 15.2-16.0.

Is the Bryant GH5SAN536**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-ton model.

How much does the Bryant GH5SAN536**AA cost to run per year?

At its rated efficiency it costs about $1,028-$2,761 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,269 in Phoenix and $2,308 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Bryant GH5SAN536**AA?

ENERGY STAR lists 63 certified combinations for this outdoor unit. The highest-rated ones use FEVA0048**+NAVA54801CK, FT5AN(B,X)C48L, FG5ANXC48L.

A good fit if…

You want a choice of indoor units - 63 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.

Questions5

What is the SEER2 rating of the Bryant GH5SAN536**AA?: The Bryant GH5SAN536**AA is rated at up to 16.0 SEER2 and 13.0 EER2 for cooling and up to 8.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 63 certified matchups SEER2 ranges from 15.2-16.0.
Is the Bryant GH5SAN536**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-ton model.
How much does the Bryant GH5SAN536**AA cost to run per year?: At its rated efficiency it costs about $1,028-$2,761 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,269 in Phoenix and $2,308 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Which indoor units work with the Bryant GH5SAN536**AA?: ENERGY STAR lists 63 certified combinations for this outdoor unit. The highest-rated ones use FEVA0048**+NAVA54801CK, FT5AN(B,X)C48L, FG5ANXC48L.
What refrigerant does the Bryant GH5SAN536**AA use?: It uses R-454B.
