What is the SEER2 rating of the CanAir 4C22SCH09H21?

The CanAir 4C22SCH09H21 is rated at up to 21.6 SEER2 and 12.6 EER2 for cooling and up to 9.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2 certified matchups SEER2 ranges from 21.2-21.6.

Is the CanAir 4C22SCH09H21 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 7,000 BTU/h at 5°F with a COP of 2.07, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the CanAir 4C22SCH09H21 cost to run per year?

At its rated efficiency it costs about $198-$644 a year in electricity in large U.S. cities, depending on climate and local rates - for example $260 in Phoenix and $550 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 CanAir 4C22SCH09H21?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use 4C22SEH09H21-P, 4C22SEH09H21.

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.
