What Size Mini Split Do I Need


When sizing a mini split system, the term 'BTU' is your guiding star. BTUs, or British Thermal Units, measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. For a room's square footage, a general rule of thumb is that you'll need approximately 20 BTUs for each square foot of living space.

Factors That Affect BTU Calculations

While square footage gives us a baseline, several additional factors can sway the BTU calculations for your mini split system. Ceiling height and insulation quality are critical elements. Other considerations include window size and sun exposure.

BTU Capacity for Hot and Cold Climates

Climate is a defining factor in selecting the appropriate BTU capacity for your mini split system. In sweltering climates, the cooling demands can be intense, requiring a system with higher BTUs to effectively combat the heat. Conversely, in frigid environments, the heating capacity must be sufficient to keep the chill at bay.
