House HVAC 3D Simulator turns a full two-story home into an interactive 3D model you can explore from any angle. Transparent walls let you see every heating, cooling, and ventilation system at once. Tap any component to learn exactly what it does, how it is sized, and how to keep it running. Built for homeowners, students, HVAC apprentices, technicians, inspectors, and anyone who wants to truly understand residential mechanical systems. EXPLORE THE 3D HOUSE Orbit, zoom, and pan around a complete home with an attic, basement utility room, garage, bedrooms, kitchen, and living areas. Toggle the walls and roof to reveal the equipment inside, and watch animated airflow move through the supply, return, and ventilation paths. EVERY SYSTEM IN ONE VIEW See how the whole home works together: gas furnace, boiler, heat pump, air handler, electric heat, and radiant floor loops; the outdoor condensing unit, evaporator coil, mini-splits, compressor, and refrigerant lines; supply and return ducts, registers, diffusers, dampers, and the ERV; filters, UV purifier, humidifier, dehumidifier, thermostats, zone controls, the breaker panel, and every safety device. COLOR-CODED CONNECTIONS Every duct, pipe, and wire is drawn and color-coded by type, so you can follow supply air, return air, exhaust, fresh air, refrigerant liquid and suction lines, hydronic piping, gas, condensate, line-voltage power, and low-voltage control wiring at a glance. A built-in legend explains each one. TAP TO LEARN Tap any component for plain-language detail: what it does, its code reference, airflow or capacity, maintenance interval, common failure modes, energy-efficiency notes, and practical contractor and service tips. LEARNING HUB Six built-in study tools. Quiz. Test yourself on fundamentals, airflow, the refrigeration cycle, thermostats, and residential code. Glossary. Clear definitions for CFM, SEER, AFUE, static pressure, superheat, subcooling, plenum, damper, and more. Guided Tour. A step-by-step walkthrough of how heating and cooling move from the equipment to every room. Fault Simulator. Diagnose a clogged filter, frozen coil, refrigerant leak, failed capacitor, blocked drain, thermostat fault, and duct leakage. Load Calculator. Estimate heating and cooling load, duct size, airflow balance, energy cost, and ventilation rate. Code Violations. Learn the most common installation mistakes and the correct practice for each. DESIGNED FOR IPHONE AND IPAD A clean, modern interface that works in portrait and landscape on both iPhone and iPad. Everything runs fully on device, with no account and no internet connection required.
