Store description excerpt
Airforge is a field toolkit for HVAC and refrigeration technicians. 33 calculators and references, built on verified data, that work entirely offline — because the mechanical room never has signal. No account. No sign-in. Nothing to load. Open the app and start working. **CHARGING, SUPERHEAT & SUBCOOLING** • Pressure-temperature (P/T) chart for 58 refrigerants — dew and bubble curves, verified point-by-point against reference thermodynamic data to within 0.0005 psi • Superheat and subcooling calculators with manufacturer target ranges • Line-set charge adder, compression ratio, target evaporator exit temperature • Uses the dew curve for superheat and the bubble curve for subcooling — the way a blend actually behaves **SYSTEM DIAGNOSIS** Enter your gauge pressures and line temperatures. Airforge ranks the likely faults — undercharge or leak, overcharge, non-condensables, restricted metering device, dirty condenser, low or high airflow, TXV problems — and shows the reasoning behind each, not just a one-word verdict. It is a second opinion for the readings you already trust. **AIR SIDE** • CFM from temperature rise, duct sizing (round and rectangular) by velocity • Static pressure, external static, target airflow • Full psychrometrics: wet bulb, dew point, enthalpy, relative humidity, grains • Delta-T check and filter sizing **ELECTRICAL** • Ohm's law and power, motor FLA reference, capacitor microfarad check • Wire ampacity and voltage drop **HEAT & COMBUSTION** • Furnace temperature rise, combustion air, gas pipe sizing • Water heating and a quick heat-load estimate **REFERENCE** • Refrigerant safety class and GWP, EPA 608 quick reference • Unit conversions and altitude / barometric correction that feeds every psychrometric calculation automatically **BUILT FOR THE JOB** • Everything works offline • Job records — save readings against a customer and address, then export a clean PDF and text or email it before you leave • Your company name, phone and licence number head every report • Pin the tools you use every day; search by refrigerant, formula or unit • Adaptive layout: comfortable on a phone, laid out properly on a tablet **FREE & PRO** The core toolkit is free, including 12 common refrigerants. Airforge Pro unlocks all 58 refrigerants and unlimited job records — a one-time purchase, no subscription. A rewarded video grants a 24-hour Pro trial so you can try it on a real call. Remove Ads is available on its own. Built by a working tradesperson, not a content farm. Found a reading that looks wrong? Email contact@tapforgeapps.com — accuracy reports go straight to the top.
