The \u003cstrong\u003eCentral Heat Pump CONFORTO MHSD | 1.5 Tons - 18,000 BTU - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eMHSD118DACFC\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eMHAH118DACFC\u003c\/strong\u003e indoor unit, an air handler that takes the place of the old furnace and pushes warm or cool air through the existing duct system.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e18.0 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.4 EER2\u003c\/strong\u003e and \u003cstrong\u003e9.3 HSPF2\u003c\/strong\u003e. The system is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified with the \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e under \u003cstrong\u003eENERGY STAR ID 3892545\u003c\/strong\u003e, its certificate still lists heating capacity at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, and it qualifies for a \u003cstrong\u003e$1,620 LogisVert grant\u003c\/strong\u003e. At 1.5 tons, this size is meant for homes where a bigger unit would run in short bursts and never really pull the moisture out of the air.\u003c\/p\u003e\u003ch3\u003eWhich homes the 1.5-ton size suits\u003c\/h3\u003e\u003cp\u003eAn \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e central heat pump suits compact homes that already have ducts: a two-level townhouse, a small well-insulated bungalow, a condo or a semi-detached house whose old electric furnace is reaching the end of its life. It also suits a dwelling served by its own duct system, such as the upper unit of a duplex that has its own furnace.\u003c\/p\u003e\u003cp\u003eFloor area alone is not enough to choose. Two homes of the same size can have very different needs depending on wall and attic insulation, window age, orientation and how airtight the envelope is. An unrenovated home from the sixties may need the next size up; a recent, well-sealed home often does fine with this one. A room-by-room load calculation settles it, and we do it before proposing a size.\u003c\/p\u003e\u003ch3\u003eWhy the right size heats and cools better\u003c\/h3\u003e\u003cp\u003eFor years, air conditioners were chosen \"a little bigger, to be safe.\" With a heat pump, that habit costs comfort. An oversized unit reaches the set point too quickly, stops, then starts again: these short cycles wear out components, leave temperature differences between rooms and, in summer, shut off the cooling before the coil has had time to remove moisture. The house is cool, but clammy.\u003c\/p\u003e\u003cp\u003eA properly sized system runs for long periods at low speed. Air moves continuously through the \u003cstrong\u003educts\u003c\/strong\u003e, the upstairs bedrooms get their share and moisture is removed over the hours. In a small home, the \u003cstrong\u003e1.5-ton\u003c\/strong\u003e size is often the one that allows this calm, steady operation, summer and winter.\u003c\/p\u003e\u003ch3\u003eHow the variable-speed heat pump works\u003c\/h3\u003e\u003cp\u003eA heat pump does not make heat, it moves it. In winter, the refrigerant captures heat from the outdoor air, even very cold air; the compressor concentrates it and sends it to the indoor unit's coil, and the blower distributes it through the ducts. In summer, a reversing valve flips the cycle: heat from the house is released outdoors.\u003c\/p\u003e\u003cp\u003eThe compressor is \u003cstrong\u003evariable-speed\u003c\/strong\u003e (\u003cstrong\u003einverter\u003c\/strong\u003e technology). Instead of running flat out or not at all, it adjusts its speed to the actual demand: it slows down in mild weather and speeds up as the cold sets in. The system runs on \u003cstrong\u003eR-410A\u003c\/strong\u003e, a refrigerant that refrigeration technicians know well.\u003c\/p\u003e\u003ch3\u003eQuebec winters, according to the certificate\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e13,500 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) with a \u003cstrong\u003eCOP of 2.60\u003c\/strong\u003e, and \u003cstrong\u003e16,500 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F) with a \u003cstrong\u003eCOP of 2.04\u003c\/strong\u003e. The two points are measured separately; we report each one as published, without extrapolating. At -15 °C, the listed capacity is about 92% of the 18,000 BTU\/h nominal size.\u003c\/p\u003e\u003cp\u003eThe certificate goes further: at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, it still lists \u003cstrong\u003e10,500 BTU\/h\u003c\/strong\u003e with a \u003cstrong\u003eCOP of 1.53\u003c\/strong\u003e. The heat pump therefore keeps heating through the coldest nights of a \u003cstrong\u003eMontreal\u003c\/strong\u003e winter, with an efficiency that remains higher than ordinary electric heating.\u003c\/p\u003e\u003cp\u003eDuring deep cold snaps, however, the home's demand can exceed what the outdoor unit supplies. In an all-electric central installation, backup heat usually comes from heating elements housed in the indoor unit, which only switch on when the heat pump is no longer enough. We size them according to the load calculation and list them in the quote.\u003c\/p\u003e\u003ch3\u003eWhat SEER2, EER2, HSPF2 and COP mean\u003c\/h3\u003e\u003cp\u003eThese ratings are measured under standardized protocols and are used to compare units with one another. Here is how to read them for this system.\u003c\/p\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSEER2 (18.0)\u003c\/strong\u003e: seasonal cooling efficiency over a typical summer.

An electric baseboard has a COP of 1; with a COP of 2.04 at -15 °C, the heat pump delivers about twice as much heat as the electricity it uses.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eCooling and dehumidification\u003c\/h3\u003e\u003cp\u003eIn summer, the same unit cools the whole house. The variable-speed compressor slows down once the temperature is reached and holds the set point without the stops and restarts of a conventional air conditioner. The coil stays cold longer, which removes more moisture: the air feels cooler at the same temperature, and a basement served by the ducts stays less damp.\u003c\/p\u003e\u003cp\u003eIn a townhouse, the upstairs bedrooms are often the warmest rooms. Cool air reaches them through the existing registers; we check that each room has a supply and that the air return is sufficient, because a closed bedroom without a return stays warmer than the rest of the house.\u003c\/p\u003e\u003ch3\u003eThe $1,620 LogisVert grant\u003c\/h3\u003e\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$1,620\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.
