Overview
Inverter air conditioners are air conditioners that employ inverter technology and work differently from conventional air conditioners. The cooling system of the device operates as follows: The motor of the inverter air conditioner starts out slowly to prevent excessive energy consumption, then ramps up to full load gradually.
Best inverter window air conditioners are designed to be installed in the window. They are compact in size and can be easily installed without any professional help.

Important Point
EER (Energy Efficiency Ratio) = BTU/W
CSPF = CSTL(Cooling Seasonal Total Load)/CSTE Cooling Seasonal Energy Consumption
You should pay greater attention to these two symptoms because they will impact the air conditioner's overall quality. BTU shouldn't be taken into too much account. Even though all models may have the same BTU, the ERR index may differ, making this a nearly essential factor to take into account when purchasing an air conditioner.
While CSPF is applicable to inverter air conditioners, EER is solely applicable to conventional air conditioners.
With rising EER and CSPF values, the air conditioner becomes more efficient.
BTU
BTUs are the units used to measure the amount of energy required to elevate a pond of water by 1 degree F (British thermal units). That is used to describe the capacity of heaters, ovens, and air conditioners as well as the calorific value of the fuel. BTU evaluates cooling capacity rather than power consumption (W). 1 BTU ~ 0.293 kW.

HP (horse power)
The air conditioner's operational capacity is expressed in HP, which is roughly comparable to 9000 BTU. Standard 1 HP = 746 W. The air conditioner thus consumes 0.746 kW per hour, or 1 kW every 4,827 hours. The size of the room increases with increasing HP.
