Description

HVAC Superheat & Subcool Calculator is the professional field diagnostic tool for AC service and system commissioning. Calculate superheat, subcooling, and saturation for 10 refrigerants including R-410A, R-454B (EPA 608 transition), and R-32 with smart charge diagnostics and color-coded results for instant field diagnostics. FEATURES: Instant Superheat & Subcooling Calculation - Get results in seconds Smart Charge Diagnostics - Normal, Low, or High with recommendations 10 Refrigerants Supported - R-410A, R-22, R-454B, R-32, R-407C, R-134a, R-404A, R-507A, R-290, R-717 Metering Device Support - TXV (expansion valve) or fixed orifice Color-Coded Results - Green/yellow/red for quick decisions P-T Saturation Data - From Honeywell, Chemours, Arkema specs Zeotropic Blend Support - Correct bubble/dew handling for blends 100% OFFLINE: All refrigerant data built-in. Works on job sites without cellular coverage. HOW IT WORKS: 1. Select refrigerant (R-410A, R-454B, R-32, etc.) 2. Select metering device (TXV or fixed orifice) 3. Enter suction pressure & temperature 4. Enter liquid pressure & temperature 5. Get instant superheat, subcooling & charge diagnosis UNDERSTANDING RESULTS: Superheat - Temperature rise above saturation on low side. Normal 10-20°F TXV, 15-25°F fixed orifice. Low indicates overcharge; high indicates undercharge or low airflow. Subcooling - Temperature drop below saturation on high side. Normal 10-20°F. Low indicates undercharge; high indicates overcharge. DIAGNOSTICS: Green - Normal charge, optimal operation Yellow - Borderline condition requiring attention Red - Undercharge, overcharge, or airflow issue SUPPORTED REFRIGERANTS: R-410A (residential), R-22 (legacy), R-454B (EPA replacement), R-32 (mini-splits), R-407C (commercial), R-134a (auto AC), R-404A (refrigeration), R-507A (low-temp), R-290 (propane), R-717 (ammonia) OPTIONAL PRO UPGRADE — $2.99 ONE-TIME IN-APP PURCHASE The following features require a separate one-time in-app purchase.
