Air Conditioner BTU Calculator

Area × Height × Planning assumption × Load adjustment factor

Before you order

  • This is a rough planning estimate. Choose the W/m³ assumption for your situation; climate, insulation, air leakage and glazing can change the load. A professional heat-loss or cooling-load calculation is needed for final equipment selection.
