Description
HVAC Refrigerant P-T Chart provides instant pressure-temperature lookup for HVAC technicians and AC service professionals. Instant pressure-temperature lookup for 10 EPA 608 refrigerants including R-454B (next-gen EPA transition replacement) and R-32 mini-split systems with NIST REFPROP-grade saturation data cross-checked against Honeywell, Chemours, and Arkema P-T charts.
FEATURES: Bidirectional Lookup — Pressure → Temp and Temp → Pressure 10 Refrigerants Supported — R-410A, R-22, R-454B, R-32, R-407C, R-134a, R-404A, R-507A, R-290, R-717 Full P-T Saturation Tables — -60°F to +150°F in 5°F steps Bubble & Dew Points — Zeotropic blend data (R-454B, R-407C, R-404A) Temperature Glide Display — Shows glide range for blends Linear Interpolation — Precise results between data points
100% OFFLINE OPERATION: Works without internet connection. All saturation data built into the app — no server calls, no delays. Perfect for job sites without cellular coverage.
HOW IT WORKS: 1. Select your refrigerant (R-410A, R-454B, R-32, etc.) 2. Choose lookup: Pressure → Temp or Temp → Pressure 3. Enter your value (PSIG or °F) 4. Get instant saturation results with bubble/dew for blends
WHY YOU NEED THIS APP FOR AC SERVICE: Every air conditioning service call requires instant saturation temperature verification. Whether measuring superheat, subcooling, or verifying system pressures during EPA 608 compliance work — you need accurate P-T data in your pocket. This app provides NIST-grade verified saturation tables for all 10 common EPA 608 refrigerants with R-454B transition support.
OPTIONAL PRO UPGRADE — $2.99 ONE-TIME IN-APP PURCHASE The following features require a separate one-time in-app purchase. They are not required to use the calculator: • Unlimited saved calculation history • PDF export of results • Dark theme • Ad-free experience
PERFECT FOR: HVAC technicians on AC service calls Refrigeration mechanics and EPA 608 certified technicians AC installers and air conditioning contractors HVAC apprentices and students preparing for EPA 608 certification Building maintenance engineers Equipment commissioning specialists and diagnostics professionals
All P-T data computed from NIST REFPROP-grade equations of state and cross-checked against Honeywell, Chemours, and Arkema manufacturer charts.
Part of HVACTools Suite — professional HVAC technician and refrigeration calculator collection.
