How efficient are Coast Air models?
Portable air conditioners
Of the 4 Coast Air portable ACs, 1 files a higher CEER than the class median and 3 fall below it.
| Class | Coast Air models | Above median | Class median | Best Coast Air |
|---|---|---|---|---|
| Single hose portable ACs (1,044) | 4 | 1 | CEER 7.3 | CEPH- |
Dehumidifiers
Of the 5 Coast Air dehumidifiers, none files a higher IEF than the class median: 1 matches it and 4 fall below it.
| DOE class | Coast Air models | Above median | Class median | Best Coast Air |
|---|---|---|---|---|
| Portable dehumidifiers, 25 to 50 pints/day (296) | 4 | 0 | IEF 1.91 | CED35A IEF 1.9 |
| Portable dehumidifiers up to 25 pints/day (253) | 1 | 0 | IEF 1.7 | CED22A IEF 1.7 |
A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.
Who makes Coast Air portable 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 9 Coast Air 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 Coast Air alone.
How much do Coast Air models cost to run?
While cooling, Coast Air portable ACs draw about 906 to 1,282 W (certified SACC divided by CEER). That's 16¢ to 23¢ an hour, or $39.50 to $55.88 for 30 days at 8 hours a day. The lowest is Coast Air CEP-081B (5,800 BTU/h SACC, CEER 6.4) and the highest Coast Air CEPH-121B (10,000 BTU/h SACC, CEER 7.8).
Running nonstop at DOE's test conditions, the 5 Coast Air 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 Coast Air CED22A (22.04 pints/day, IEF 1.7) and the highest Coast Air CED50A (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.

Questions about Coast Air
- Is Coast Air a good dehumidifier brand?
- How its 5 dehumidifiers compare on efficiency with their DOE class is above. All 5 are filed under Coast Air alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
- Does Coast Air make a 50 pint dehumidifier?
- Yes, by the 2019 DOE test: 2 of its models certify 49.5 pints/day or more, led by Coast Air CED50A at 49.93 pints/day. By DOE class: 1 in the up to 25 pints/day class and 4 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
- Which Coast Air dehumidifier is the most efficient for its size?
- Coast Air CED22A, at IEF 1.7: higher than 94 of the 253 in its DOE class (portable dehumidifiers up to 25 pints/day). At the other end are Coast Air CED35A, Coast Air CED35B, Coast Air CED50A and 1 more, at IEF 1.9, higher than 60 of the 296 in its class.
