The ADD-ON approach builds on these. The heat pump coil sits on the furnace's air outlet; when the heat pump runs, the furnace blower pushes air through that coil, which warms it in winter and cools it in summer.\u003c\/p\u003e\u003cp\u003eThe heat pump thus takes over the cooling and most of the heating. The furnace's electric elements stay ready to provide backup heat during deep cold. There is no unit to remove and no indoor unit to fit: only a coil, a line set, an outdoor unit and a suitable thermostat.\u003c\/p\u003e\u003ch3\u003eWhich homes the 1.5-ton size suits\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e1.5-ton\u003c\/strong\u003e size, or \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e, is meant for compact homes heated by an electric furnace: a townhouse, a small bungalow, a semi-detached house in \u003cstrong\u003eLongueuil\u003c\/strong\u003e or on the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e. These are often homes without central air conditioning, where a window unit had to do.\u003c\/p\u003e\u003cp\u003eFor an ADD-ON system, the size is chosen first according to cooling needs, then according to the share of heating the heat pump will be able to take on. An oversized unit would cool in bursts and remove moisture poorly. The room-by-room load calculation accounts for insulation, windows and orientation; we do it before proposing a size.\u003c\/p\u003e\u003ch3\u003eA 17.5 in. coil matched to the furnace\u003c\/h3\u003e\u003cp\u003eThe width shown in the title, \u003cstrong\u003e17.5 in.\u003c\/strong\u003e, is the coil's width. It must match the width of the furnace's air outlet so that air passes through the whole coil without bypassing its edges. It is a common width for residential furnaces, but we always measure on site before confirming the model.\u003c\/p\u003e\u003cp\u003eThe coil fits between the furnace and the supply plenum. Depending on the height available in the mechanical room, the plenum is adjusted or rebuilt. A condensate drain is connected to the coil, since it produces water in cooling mode.\u003c\/p\u003e\u003ch3\u003eWhich unit heats, and when\u003c\/h3\u003e\u003cp\u003eA compatible thermostat decides when the heat pump heats on its own and when the electric furnace's elements come into play. As long as the heat pump holds the set point, it heats alone. When it is no longer enough, in deep cold, the thermostat brings in the electric elements as auxiliary heat, then takes them out as soon as the heat pump is enough again.\u003c\/p\u003e\u003cp\u003eThe moment the backup comes in is set according to the heat pump's capacity, the home's heat loss and your comfort preferences.
