Why Manual JSD Calculations Matter in South Carolina

Every climate is different, and HVAC systems must be sized correctly to handle the local weather conditions.

Homes in South Carolina experience unique heating and cooling demands due to factors such as:

• Outdoor design temperatures

• Solar heat gain

• Insulation levels

• Window performance

• Air infiltration

• Humidity loads

A proper Manual J load calculation analyzes all of these factors to determine the exact heating and cooling capacity your home requires.

Oversized systems can lead to:

• Poor humidity control

• Short cycling

• Higher energy bills

• Reduced equipment lifespan

Undersized systems may struggle to maintain comfortable indoor temperatures during extreme weather.

A properly sized HVAC system ensures comfort, efficiency, and long-term reliability.
