What is the SEER2 rating of the AIREASE 4SHP22LX148P-**A?

The AIREASE 4SHP22LX148P-**A is rated at up to 19.5 SEER2 and 12.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the AIREASE 4SHP22LX148P-**A 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 4-ton model.

How much does the AIREASE 4SHP22LX148P-**A cost to run per year?

At its rated efficiency it costs about $1,136-$3,254 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,430 in Phoenix and $2,741 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 AIREASE 4SHP22LX148P-**A?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated one uses BCE7S60M*4X.

What refrigerant does the AIREASE 4SHP22LX148P-**A 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.

4-ton central heat pump · 4SHP22LX SERIES

AIREASE 4SHP22LX148P-**A

Excellent cooling efficiency and below average heating efficiency for a 4-ton central heat pump, but not rated for cold climates.

Ranks #24 of 319 4 ton central heat pumps for cooling efficiency, and costs about $1,340 a year to run in a mixed climate like Atlanta.

SEER2: 19.5 Cooling efficiency over a season
Excellent · beats 91%
HSPF2: 8.5 Heating efficiency over a season
Below average · beats 38%
EER2: 12.0 Cooling efficiency on a 95°F day
Average · beats 64%
Heat at 5°F: 23,200 BTU/h52% of its 47°F output
Excellent · beats 92%

A good fit if…

You want low cooling bills - its SEER2 beats 91% of central heat pumps.
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 central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.

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.
