HVAC Pipe Sizer Plus vs HVAC AI

The HVAC Pipe Sizer Plus application is a combination of three (3) of our individual pipe sizing applications including: 1. HVAC Pipe Sizer - Liquid 2. HVAC Pipe Sizer - Steam 3. HVAC Pipe Sizer - Gas Plus This app is a universal app that works on both the iPhone and iPad and adjusts its screen size accordingly. The "HVAC Pipe Sizer - Gas" module allows you to quickly size a simple low (less than or equal to 1.5 psi) and high (greater than 1.5 psi) pressure gas piping system by inputting a number of piping and gas properties. The "HVAC Pipe Sizer - Steam" module allows you to size a steam pipe run, and it also includes a bonus steam table calculator. The "HVAC Pipe Sizer - Liquid" module allows you to size a pipe run with many different types of liquids (or fluids), pipe material and fitting types. This application includes all of the great features of the individual pipe sizer apps such as the use of slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. It also allows you to specify different types of liquids, gases, pipe material types, fitting quantities, min and max ranges, and step values. Also, you can display a wide variety of English and Metric units. The "HVAC Pipe Sizer Plus" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. In addition, we developed a number of customized apps for ASHRAE, DNV GL, and other organizations. We also offer the following additional apps for the iPhone and iPad: 1. HVAC Residential Load Calcs for iPhone and iPad 2. HVAC Quick Load Plus 3. HVAC Quick Load 4. HVAC Toolkit 5. HVAC Pipe Sizer – Gas Low Pressure 6. HVAC Pipe Sizer - Gas High Pressure 7. HVAC Pipe Sizer – Liquid 8. HVAC Pipe Sizer – Steam 9. Steam Tables 10. Psychrometric Plus 11. Psychrometric LT 12. HVAC Pipe Sizer Plus 13. HVAC Pipe Sizer Gas Plus 14. HVAC Toolkit Ultimate 15. HVAC Equipment Locator 16. HVAC ResLoad-J 17. HVAC Psych HD

HVAC AI is the all-in-one app for HVAC technicians, engineers and students. Diagnose faults, read error codes, calculate refrigerant values, and replace your old laminated PT chart with the Refrigerant Slider AI. Carry one professional HVAC toolbox in your pocket instead of juggling manuals, charts and separate apps. DIAGNOSE FAULTS IN MINUTES Scan the unit, enter refrigerant pressures or temperatures, and capture key readings. In seconds the app delivers probable causes, step-by-step repair instructions and preventive maintenance tips. From refrigerant charge problems in heat pumps to airflow and wiring errors in VRF systems, HVAC AI cuts the guesswork on every service call. SMART HVAC TOOLS Refrigerant Slider AI (digital PT chart) for dozens of refrigerants, including R22, R410A, R32, R134a and R1234yf. Superheat and subcooling calculators to charge precisely and protect compressors. Smart wiring simulator to validate diagrams before energizing. Universal HVAC remote to control multiple air conditioner brands. Carbon tracker and energy optimizer to cut energy use. NEW: INTERACTIVE HVAC SIMULATOR Practice on a full refrigeration cycle simulator with compressor, condenser, evaporator and expansion valve. Change the refrigerant, adjust the setpoint and watch the system respond in real time. Perfect for students, apprentices and technicians who want to master the cycle without risking real equipment. NEW: LEARNING PATH AND CALCULATORS Follow a gamified HVAC learning path with levels, quizzes, practice tests and achievements, and prepare for certification exams. The built-in calculators cover BTU, cooling and heating load, airflow, CFM, tonnage, duct sizing and refrigerant charge, so you always have the right number on site. NEW: PRO QUOTE BUILDER Create professional quotes and PDF service reports from the field in seconds. Use the scanner and QR codes to track each unit, capture the client's digital signature, and share by message instantly. Multi-currency support helps you quote anywhere. 24/7 AI TECHNICAL SUPPORT The built-in AI assistant interprets error codes, guides superheat and subcooling adjustments, helps with wiring and sensor calibration, and recommends efficiency improvements tailored to the system. WHY CHOOSE HVAC AI Diagnose faults in minutes, not hours. Replace paper PT charts with the Refrigerant Slider AI. Calculate superheat and subcooling accurately. Train on the interactive simulator and learning path. Run professional calculators for any job. Quote and report like a pro from the field. FOR HVAC PROFESSIONALS EVERYWHERE HVAC AI adapts to residential, commercial and industrial work: split systems, multi-split, VRF and rooftops, walk-in coolers, freezers and supermarket refrigeration, furnaces and heat pumps. Whether you install, repair or maintain air conditioning and refrigeration systems, HVAC AI gives you the diagnostics, tools, simulator, training and quoting you need. WORKS FOR EVERY MAJOR BRAND Look up fault codes and service guidance for Daikin, Carrier, Trane, Rheem, York, Mitsubishi, LG, Samsung and more. The brand code database keeps growing with every update, so the answer you need is ready when you are on site. BUILT FOR THE FIELD Most tools work without a signal, so you can calculate, check the PT chart and run the simulator in basements, rooftops and mechanical rooms. Large inputs and clean layouts mean less tapping and more working. HVAC AI is designed to be fast, reliable and genuinely useful on a real job, not just in the office.
