This multi-split heat pump system incorporates several indoor units connected to just one outdoor unit; the indoor units include a wall-mounted unit, floor-mounted, ceiling cassette, and mini-air handler.
This plot shows a heat pump’s minimum and maximum cooling capacities overlaid with a home’s cooling load line, allowing a designer to assess how well-suited the equipment is for the specific home.
This plot shows a heat pump’s minimum and maximum heating capacities overlaid with a home’s heating load line as well as the annual heating load hours for the home, allowing a designer to assess how well-suited the equipment is for the specific home.

This single-zone mini-split ductless heat pump has only one indoor wall-mounted unit and one outdoor unit.
This traditional centrally ducted heat pump heats and cools the entire home through a network of ducts.
This upflow air handler for a traditional heat pump has an electric resistance auxiliary heating element located at the top of the unit (circled in red).
Wrong: Sized per Approach 1 or 2, this heat pump’s modulating zone has a small overlap with the home’s heating load line, resulting in a large amount of short-cycling; the unit will require backup heat when the temperature is below 25°F
Wrong: Sized per Approach 3, there is minimal overlap between this heat pump’s modulating zone and the home’s heating load line, causing excessive short-cycling; it will require backup heat and may not contribute significantly at temperatures below 5°F
Wrong: Sized per Approach 3, there is small overlap between this heat pump’s modulating zone and the home’s heating load line, resulting in excessive short-cycling; it will require backup heat when the temperature is below 5°F
Wrong: This heat pump is oversized even for Approach 4, and its modulating zone has a small overlap with the home’s heating load line, resulting in a large amount of short-cycling.
