A selection guide for R134a capillary tubes typically depends on the (measured in BTU/h or Watts) and the evaporator temperature . While many technicians use horsepower (HP) as a quick reference, professional guides from manufacturers like Tecumseh recommend sizing based on actual heat removal capacity for better precision.
