How efficient are Seasons models?
Portable air conditioners
Of the 6 Seasons portable ACs, 2 file a higher CEER than the class median and 4 fall below it.
| Class | Seasons models | Above median | Class median | Best Seasons |
|---|---|---|---|---|
| Single hose portable ACs (1,044) | 6 | 2 | CEER 7.3 | SM10PXR1 CEER 7.9 |
Window and room air conditioners
Of the 20 Seasons window ACs, none files a higher CEER than the class median: 20 match it.
| DOE class | Seasons models | Above median | Class median | Best Seasons |

Dehumidifiers
Of the 8 Seasons dehumidifiers, 2 file a higher IEF than the class median, 2 match it and 4 fall below it.
| DOE class | Seasons models | Above median | Class median | Best Seasons |
|---|---|---|---|---|
| Portable dehumidifiers, 25 to 50 pints/day (296) | 6 | 2 | IEF 1.91 | SD35CB1 IEF 2.01 |
| Portable dehumidifiers up to 25 pints/day (253) | 2 | 0 | IEF 1.7 | SD22C1 IEF 1.7 |
A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.
Who makes Seasons portable ACs, window ACs and dehumidifiers?
DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.
None of the 34 Seasons basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to Seasons alone.
How much do Seasons models cost to run?
While cooling, Seasons portable ACs draw about 820 to 1,282 W (certified SACC divided by CEER). That's 15¢ to 23¢ an hour, or $35.72 to $55.88 for 30 days at 8 hours a day. The lowest is Seasons SM05PAR1 (5,000 BTU/h SACC, CEER 6.1) and the highest Seasons SM13R1 (10,000 BTU/h SACC, CEER 7.8).
While cooling, Seasons window ACs draw about 380 to 2,500 W (DOE's listed power input). That's 7¢ to 45¢ an hour, or $16.56 to $108.96 for 30 days at 8 hours a day. The lowest is Seasons SW05MC1 (5,000 BTU/h, CEER 13.1) and the highest Seasons SW24V2 (24,000 BTU/h, CEER 13.8).
Running nonstop at DOE's test conditions, the 8 Seasons dehumidifiers with both figures use 6.13 to 12.43 kWh a day. That's about $1.11 to $2.26 a day, or $33.42 to $67.74 for 30 days. The lowest is Seasons SD22C1 (22.04 pints/day, IEF 1.7) and the highest Seasons SD50C1 (49.93 pints/day, IEF 1.9).
Real use cycles on and off with the humidity, so the dehumidifier figures are the upper end for a day of nonstop running.
At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.
Questions about Seasons
- Is Seasons a good dehumidifier brand?
- How its 8 dehumidifiers compare on efficiency with their DOE class is above. All 8 are filed under Seasons alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
- Does Seasons make a 50 pint dehumidifier?
- Yes, by the 2019 DOE test: 3 of its models certify 49.5 pints/day or more, led by Seasons SD50C1 at 49.93 pints/day. By DOE class: 2 in the up to 25 pints/day class and 6 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
- Which Seasons dehumidifier is the most efficient for its size?
- Seasons SD35CB1 and Seasons SD50CP1 tie at IEF 2.01: higher than 161 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). At the other end are Seasons SD35C1, Seasons SD35CA1, Seasons SD50C1 and 1 more, at IEF 1.9, higher than 60 of the 296 in its class.
