Low vs HVAC AI

Low-GWP Tool is now part of the new Ref Tools app, our essential, all-in-one mobile app for air conditioning and refrigeration technicians. Ref Tools gives you access to the tools, guidance, support, and information you need—on the job and in the field. Download Ref Tools to access the latest version of Low-GWP Tool. Retrofitting refrigeration systems to more climate-friendly refrigerants is much easier with the right tools in hand—and the first one you should reach for is Low-GWP Tool. Low-GWP Tool ensures compatibility with the TXV and uses a simple calculation to show the indicative capacity difference of a retrofit refrigerant. Simply enter basic information like TXV type, current refrigerant, operating range, and retrofit refrigerant, and Low-GWP Tool will verify that your refrigerant choice is efficient, environmentally friendly, and compatible.

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. Download HVAC AI today and transform the way you diagnose, repair, learn, quote and optimize HVAC systems.
