About this app

House HVAC 3D Simulator puts a complete residential HVAC system in your hands — rendered in real-time 3D so you can orbit, zoom, and tap every component to understand exactly how heating, cooling, ventilation, and controls work together inside a home.

INTERACTIVE 3D HOUSE
- Fully navigable 3D model of a two-story house with basement
- Pinch to zoom, drag to orbit — explore from any angle
- Toggle walls transparent to see inside every floor
- Hide or show the roof to expose second-floor and attic equipment

48 HVAC COMPONENTS
Every major system is modelled with recognisable geometry:
- Heating — gas furnace, hydronic boiler, air handler, heat pump, radiant floor
- Cooling — condensing unit, evaporator coil, mini-split, condensate pump
- Refrigeration — compressor, condenser coil, expansion valve, liquid & suction lines
- Ductwork — supply plenum, trunk ducts, registers, return grilles, flex duct, zone damper
- Ventilation — ERV/HRV unit, bath exhaust fan, range hood, fresh-air intake
- Air Quality — media filter, UV purifier, humidifier, dehumidifier, CO detector
- Controls — smart thermostat, zone panel, control board, pressure switch
- Electrical — breaker panel, HVAC disconnect, gas shutoff, flue vent, smoke detector

TAP TO LEARN
Tap any component to open a detailed info panel explaining what it does, how it works, and where it fits in the overall system.

SYSTEM FILTER
Instantly isolate any subsystem — show only Cooling, only Ductwork, only Controls — or view all systems together.

CONNECTION PIPES & WIRING
Toggle colour-coded connection lines to see how components are linked:
- Orange — supply air ducts • Blue — return air
- Yellow — gas lines • Dark red — hydronic piping
- Copper — refrigerant liquid • Cyan — refrigerant suction
- Light blue — condensate • Red — electrical power
- Purple — control wiring • Green — fresh air
- Gray — exhaust ducts

LEARNING HUB
Six built-in learning modules:
- Quiz — test your HVAC knowledge across fundamentals, airflow, refrigeration, and code
- Glossary — CFM, SEER, AFUE, static pressure, superheat, and 40+ terms defined
- Guided Tour — step-by-step walkthrough of how heating and cooling move through the house
- Fault Simulator — diagnose clogged filters, frozen coils, refrigerant leaks, and more
- Load Calculator — heat load, duct sizing, airflow, energy use, and ventilation estimates
- Code Violations — common installation mistakes with explanations and fixes

FOR STUDENTS, TECHNICIANS & HOMEOWNERS
Whether you are studying for an HVAC certification, training on the job, or simply trying to understand your home's mechanical systems, House HVAC 3D gives you a clear, hands-on reference you can explore at your own pace.

EDUCATIONAL DISCLAIMER
This app is for general educational purposes only. Code references (ASHRAE, NEC, NFPA, IRC, IMC, ACCA) are cited for educational context and vary by jurisdiction. All HVAC installation and service work must be performed by licensed professionals.
