Explore residential heating, cooling, air distribution, ventilation, refrigeration, air quality, controls and electrical equipment in one coordinated house model. Five separate installation models show furnace/central AC, ducted heat pump, ductless mini-split, hydronic radiant and balanced ventilation systems.
Drag to orbit, scroll or pinch to zoom, and use right-drag or two fingers to pan. Camera presets include front, back, side and floor-plan views. Find equipment focuses the model on a selected type. Floor, area, system and device filters help expose equipment inside the building. On phones, expand View controls for the additional filters and guided activities.
Choose one of the five installations, reveal its equipment interiors, and step through its operating modes. The selected steps coordinate equipment highlights and available animated paths. Schematics includes the system overview and 16 supporting drawings across the five installations: power and controls, refrigerant, condensate drainage, fuel and venting, expansion/fill/relief, mixing, and separated ventilation passages. Selecting a symbol focuses its equipment and coordinated explanation. Supporting drawings also have guided operating steps and equipment reference links.
Explore standard-air sensible heat, approximate water heat transfer, continuity-based duct area and a psychrometric state point. Assumptions and units appear beside the results. These worksheets and spatial models are educational references; they do not establish building loads, equipment selection, code compliance or a complete installation design.
Yes. Active All-Access unlocks the house and commercial HVAC explorers through the existing HVAC tools access. Restore access with your purchase email if needed.
Yes. Use a modern browser with WebGL. The workspace adapts to smaller screens, with touch orbit, pinch zoom, expandable controls and equipment details below the model.
No. The route markers illustrate selected system paths and operating steps. They are not airflow, pressure, refrigerant or heat-transfer simulations. The separate learning worksheets state their own calculation assumptions.
Furnace with central AC, ducted heat pump, ductless mini-split, hydronic radiant and balanced ventilation. Each has an exterior/interior variant and coordinated operating steps. The whole-house overview includes 48 equipment types.
