What size HVAC system do I need?

  1. Square footage: The size of the space being cooled or heated is a key factor in determining the capacity of the HVAC system.

  2. Climate: The local climate, including temperature and humidity levels, plays a significant role in sizing the system. Areas with extreme temperatures or high humidity may require larger systems.

  3. Insulation: The level of insulation in the walls, attic, and windows affects the heating and cooling load of the building. Well-insulated spaces may require smaller HVAC systems.

  4. Orientation and windows: The direction the building faces and the number and size of windows impact the amount of heat gain or loss. Buildings with large windows or that face direct sunlight may need larger systems.

  5. Occupancy and usage: The number of occupants, their activities, and the specific use of the building (e.g., residential, commercial, industrial) influence the heat load and ventilation requirements.

  6. Air leakage: The overall tightness of the building's envelope affects the load calculation. Buildings with higher air leakage rates may require larger HVAC systems.
