  2. Consider Insulation and Ceiling Height: Take into account the insulation quality of your room. If it’s well-insulated you can use the room’s actual square footage. If It is poorly insulated increase the square footage by 10-15%. Also consider the room’s ceiling height as taller ceilings may require more cooling capacity.
  3. Calculate BTU Requirement: For every square foot of Space you will need a specific amount of BTUs (British Thermal Units) for cooling. As a general rule of thumb estimate 20 BTUs per sq. ft. for a well-insulated room and 25 BTUs per sq. ft. for a poorly insulated room or if the room has high ceilings.
  4. Adjust for Other Factors: Consider additional factors that may affect the cooling load such as the number of occupants sunlight exposure and heat-generating appliances in the room. Add 600 BTUs for each person 1,000 BTUs for each window and 4,000 BTUs for each major heat-generating appliance.
  5. Choose the Right BTU Rating: Once You have calculated the total BTU requirement for your room choose a portable air conditioner with a BTU rating that closely matches this number. If the available options are slightly below or above the calculated BTUs It is generally better to choose a slightly higher capacity for more effective cooling.

Remember Selecting the right size portable air conditioner is essential for optimal performance. An undersized unit will struggle to cool the room adequately while an oversized one may cycle on and off frequently wasting energy and potentially leading to temperature inconsistencies. By following these steps you can make an informed decision and ensure a comfortable and efficient cooling solution for your room.
