Question

How many BTU on a window AC is good enough to cool down a two bedroom 988 sq ft single family home?

Answer 1

Determining the appropriate BTU (British Thermal Units) rating for an air conditioner to cool a specific space involves considering various factors such as the square footage, ceiling height, insulation, climate, and sunlight exposure. While a precise calculation requires a detailed analysis, a general guideline for cooling a 988 sq ft home would be to consider a range of 18,000 to 24,000 BTU.

Here's a breakdown of the recommended BTU range based on square footage:

• For moderately insulated homes: 20 BTU per square foot

  • 988 sq ft x 20 BTU = 19,760 BTU

• For poorly insulated homes or hotter climates: 25 BTU per square foot

  • 988 sq ft x 25 BTU = 24,700 BTU

Considering this range, a window air conditioner with a BTU rating of 18,000 to 24,000 would generally be suitable for cooling a two-bedroom 988 sq ft single-family home. It's important to note that other factors, such as the layout of the home, the number of windows, and any additional heat sources, should also be taken into account.

To ensure the most accurate recommendation for your specific situation, it is advisable to consult with an HVAC professional who can assess your home's unique characteristics and provide personalized advice on the appropriate BTU rating for your window air conditioner.
