What size air conditioner do you need for a 3100 sq ft home?

To determine the appropriate size air conditioner for a 3,100 sq ft home, you typically need to consider the BTU (British Thermal Unit) requirement, which is about 20 BTU per square foot. This would suggest a need for approximately 62,000 BTUs. However, factors such as ceiling height, insulation quality, number of Windows, and local climate can affect this calculation, so it's advisable to consult with an HVAC professional for a precise assessment.
