INDEPENDENT TOOL · SOURCED ESTIMATE
Before choosing an air conditioner, check whether it makes sense for your room.
ClimJuste estimates a cooling-capacity range, explains every adjustment, and may advise you not to buy a portable air conditioner.
CAPACITY ESTIMATE
Describe the hottest room
The estimate starts with the ENERGY STAR room-size table, then shows every adjustment. ADEME notes that single-hose portable units are often less efficient and noisier.
This range is not a heat-load calculation, a temperature promise, or an estimate of electrical consumption.
A number is only useful when its limits are visible.
01
Capacity, not consumption
BTU/h describe how much heat is removed. They do not directly state electrical input power or running cost.
02
Exhaust setup comes first
A hose passed through a partly open window lets hot air back in and sharply reduces the value of a single-hose unit.
03
No false precision
The result is an indicative range. An open-plan or unusual room requires a more complete assessment.
