A 7000 BTU (British Thermal Unit) portable air conditioner would generally not be sufficient to effectively cool a 2000 square feet home. The cooling capacity required for a specific space depends on various factors, including the size of the area, insulation, ceiling height, number of windows, heat-generating appliances, and climate conditions.
As a rough estimate, a 7000 BTU portable air conditioner is typically suitable for cooling small rooms or spaces up to around 250-300 square feet. To cool a 2000 square feet home adequately, you would generally need an air conditioner with a higher cooling capacity.
It's recommended to use a cooling capacity calculator or consult with an HVAC professional to determine the appropriate cooling capacity needed for your specific home. They can consider all the relevant factors and provide you with a more accurate assessment of the BTU requirements for efficient cooling.
