Why is it essential to calculate the cfm accurately in an HVAC system installation?

To determine the color of the air
To ensure proper air circulation and ventilation
To measure the humidity level indoors
To regulate the outdoor temperature

The correct answer is: To ensure proper air circulation and ventilation

Calculating the cfm, or cubic feet per minute, is an important step in an HVAC system installation because it helps ensure proper air circulation and ventilation. Option A is incorrect because air color is not a factor in HVAC installation. Option C is incorrect because humidity level can be measured separately from cfm. Option D is incorrect because outdoor temperature regulation is not directly related to cfm calculation. In summary, calculating the cfm accurately is essential for proper air circulation and ventilation in an HVAC system installation.
