Manual J - Residential Calculations in South Carolina
Summers in South Carolina are hot and humid, with daytime temperatures averaging near 90 °F (32 °C) in most places across the state. A good HVAC system is vital to meet your daily energy needs, making your home comfortable. Manual J protocols for HVAC design involve reviewing the amount of heating and cooling you need for your home. Accurate calculations are vital to determine how efficient or powerful your HVAC system should be.
A Manual J calculation, designed by the Air Conditioning Contractors of America (ACCA), relies on computer programs to accurately assess the demands of a house. A perfectly designed HVAC system will generate the correct temperature without wasting energy. Perfect sizing depends on various factors, including the region’s climate, the home’s square footage, the height of the space, insulation grade, the number of windows, and building air tightness.
Manual N - Light Commercial Properties in South Carolina
The Manual N standard determines the proper size of HVAC systems in light commercial properties. When assessing the building’s needs, we determine the amount of heat gained or lost internally and externally. We work with small to medium-sized commercial buildings that need HVAC load calculation. Our ProCalcs experts know how to calculate commercial heating and cooling load accurately to make sure you have a correctly sized system for your property.
Manual N takes into account factors such as building orientation, the interior lighting, the number of windows and how they appear, number of occupants, and more. We understand that modern commercial construction involves new building techniques and materials and make sure everything is up to code for comfort and ventilation requirements. Our HVAC designs for light commercial buildings based on Manual N calculations promote safety and functionality.
