What is the SEER2 rating of the Hisense AUWR-48U3SP2?

The Hisense AUWR-48U3SP2 is rated at up to 17.5 SEER2 and 10.1 EER2 for cooling and up to 8.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2 certified matchups SEER2 ranges from 15.6-17.5.

Is the Hisense AUWR-48U3SP2 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 34,600 BTU/h at 5°F with a COP of 1.94, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the Hisense AUWR-48U3SP2 cost to run per year?

At its rated efficiency it costs about $1,290-$3,527 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,601 in Phoenix and $2,955 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 Hisense AUWR-48U3SP2?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use AUH-48UX3SEH2, DC61A44-245R.

What refrigerant does the Hisense AUWR-48U3SP2 use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

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.
