Refrigerant Calculator Suite
Professional HVAC calculation tools for pressure-temperature conversions, system sizing, charge calculations, and performance analysis. Designed for EPA certified refrigerants.
Pressure-Temperature Calculator
Convert between pressure and temperature for different refrigerants. Essential for system diagnostics and performance analysis.
Calculation Results
How to Use
Enter either temperature OR pressure (not both) and select your refrigerant type. The calculator will determine the corresponding saturation condition.
Refrigerant Charge Calculator
Calculate the proper refrigerant charge for your system based on line set length, system type, and manufacturer specifications.
Recommended Charge
Important Note
Always refer to manufacturer specifications for base charge amounts. This calculator provides estimates based on line set additions.
Superheat & Subcooling Calculator
Calculate superheat and subcooling values for system performance analysis and charge verification.
System Analysis
System Sizing Calculator
Calculate proper system capacity based on space requirements, load calculations, and efficiency factors.
Recommended System Size
Sizing Guidelines
This calculator provides estimates based on simplified load calculations. For critical applications, always perform a detailed Manual J load calculation.
Unit Conversions
Convert between different units commonly used in HVAC work - temperature, pressure, capacity, and more.
