How do you read an AC label without mixing up BTU and watts?

The most common comparison error is treating cooling capacity as electricity use. They are different numbers.

The three numbers that matter

ValueWhat it meansHow we use it
Cooling Capacity / BTU/hHow much heat the unit can removeCompare it with the estimated room-load range
Input Power / WElectrical power at the stated test/operating conditionUse it to read the unit’s electrical demand—not as BTU
SEER/EER or energy labelAn efficiency indicator, not a bill by itselfUseful when comparing units with similar capacity

Do not convert BTU into watts to calculate a bill

Cooling output is not electricity consumption. Two 18,000 BTU units can have different electrical input and efficiency, so the checker asks for Input Power from the unit’s specifications instead of guessing it from BTU.

Copy the specification values without guessing

Copy these values exactly as shown on the product label or manufacturer specification. If a field is missing, leave it blank instead of deriving it from another number.

Copy thisAccepted formCommon mistake
Model / model numberThe full letter-and-number stringCopying only the series name and mixing two models
Cooling Capacity18,000 BTU/h or 5.27 kW coolingCopying Input Power as capacity
Input Power1,650 W or 1.65 kW electricalConverting BTU/h to watts and treating it as consumption
Annual energy useThe published kWh/year valueInventing it from assumed operating hours
Compressor typeInverter / Fixed speed / UnknownAssuming inverter from an unclear marketing name

When the label uses another unit

  • Cooling capacity in kW: multiply cooling kW by about 3,412 for BTU/h.
  • Cooling capacity in tons: multiply tons by 12,000 for BTU/h.
  • Electrical input in kW: multiply electrical kW by 1,000 for W.

The checker can extract these fields from pasted specification text, but it always shows what it found so you can verify the values before relying on them.

Verify the energy label

SASO’s “Taqakkad” service can help consumers verify energy-efficiency label information, including cooling capacity, annual energy use and input power for a specific model. Prefer the official source when a retailer page is incomplete.

Return to the checker and enter BTU plus Input Power after you find them.
