Why is a Manual J Calculation required in Orlando?

In the Orlando area, the Florida Building Code requires a Manual J Load Calculation to ensure HVAC systems are not oversized. Oversized units in Central Florida fail to remove humidity, leading to mold growth and poor indoor air quality. Our calculations account for Orlando’s specific design conditions (94°F summer dry bulb) to guarantee comfort.
