How this is calculated
- Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
- Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
- Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
- We do not estimate watts or hourly cost: the source data does not include them.

Frequently asked questions
How much electricity does the TCL H6W4KW use?
ENERGY STAR lists 328.5 kWh per year under typical test conditions, which is calculated with U.S. Department of Energy test procedures for a typical cooling season. Your use will differ with the climate, how many hours a day you cool and the temperature you set.
How much does it cost to run?
At statewide average residential prices, the listed annual use costs about $41.79 in Louisiana and $157.68 in Hawaii (EIA, 2026-07). Your own utility rate may be different; enter it in the calculator.
How does the TCL H6W4KW compare with similar models?
Among 50 ENERGY STAR certified window models with a similar cooling capacity, it ranks 31st lowest in annual energy use. Its 328.5 kWh per year is 10% above the median of 298 kWh.
What does the CEER number mean?
The combined energy efficiency ratio is the cooling output in BTU for each watt-hour of electricity used. This model is listed at 13.7 BTU/Wh. A higher number means more cooling for the same electricity.

Methodology and sources
Model data comes from the ENERGY STAR Certified Room Air Conditioners dataset (EPA). Electricity prices are statewide average residential prices from the U.S. EIA, latest period July 2026. Values are stored locally and refreshed by scheduled imports. Missing values are left blank, never estimated.
