What is the SEER2 rating of the Hisense AST-09UW3RGE00?

The Hisense AST-09UW3RGE00 is rated at up to 23.0 SEER2 and 13.0 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 Hisense AST-09UW3RGE00 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 9,000 BTU model.

How much does the Hisense AST-09UW3RGE00 cost to run per year?

At its rated efficiency it costs about $185-$578 a year in electricity in large U.S. cities, depending on climate and local rates - for example $240 in Phoenix and $492 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Hisense AST-09UW3RGE00 the same as the Hisense AST-09UW3RGG00?

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 Hisense AST-09UW3RGE00?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses HISENSE AST-09UW3RGE**00.

9,000 BTU mini-split heat pump · HiULTRA

A good fit if…

You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You mainly need heat - its HSPF2 is below average for mini-splits.

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.
