The \u003cstrong\u003eWall-Mounted Heat Pump CONFORTO MHWAL | 9,000 BTU - R410A\u003c\/strong\u003e is a solid choice for this room: a size suited to a closed bedroom, and high cooling ratings, measured and published.\u003c\/p\u003e\n\u003cp\u003eIts certified ratings are \u003cstrong\u003e28.1 SEER2\u003c\/strong\u003e, \u003cstrong\u003e16.2 EER2\u003c\/strong\u003e and \u003cstrong\u003e11.5 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 2495124\u003c\/strong\u003e. Summer and winter, the same wall head conditions the room.\u003c\/p\u003e\n\u003ch3\u003eThe top floor, where heat builds up\u003c\/h3\u003e\n\u003cp\u003eA bedroom under the eaves or on the second floor of a cottage receives heat from above. If the roof insulation is thin or the room has sloped walls, the ceiling stays warm until late in the evening. Fans stir this air without cooling it, and a window air conditioner blocks the view and lets warm air in around the frame.\u003c\/p\u003e\n\u003cp\u003eA nominal capacity of \u003cstrong\u003e9,000 BTU\/h\u003c\/strong\u003e suits an upstairs bedroom of ordinary size. When the room has a lot of glass, faces west or has weak roof insulation, we check it with a load calculation: the heat coming through the roof can justify a larger size. We do not oversize on principle, because a unit that is too big cools quickly, stops and leaves the humidity in the room.\u003c\/p\u003e\n\u003ch3\u003eA 16.2 EER2 rating for heat-wave days\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the nominal capacity is \u003cstrong\u003e9,000 BTU\/h\u003c\/strong\u003e. The \u003cstrong\u003eEER2\u003c\/strong\u003e rating measures efficiency at the most demanding moment: a hot day, when the unit works hardest. At \u003cstrong\u003e16.2 EER2\u003c\/strong\u003e, this pairing stays efficient precisely during heat waves, when a bedroom under the roof needs it most.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSEER2\u003c\/strong\u003e rating describes efficiency over the whole summer, mild days included. At \u003cstrong\u003e28.1 SEER2\u003c\/strong\u003e, cooling this room takes little electricity for each hour of comfort, from June to September.\u003c\/p\u003e\n\u003ch3\u003eHumidity, the other half of summer comfort\u003c\/h3\u003e\n\u003cp\u003eA bedroom that is cool but humid is still unpleasant: the sheets stick, the air feels heavy. The heat pump's \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e addresses this by running long at low speed once the room reaches the set point. The indoor coil stays cold, moisture from the air condenses on it and drains away. This continuous \u003cstrong\u003edehumidification\u003c\/strong\u003e lets you sleep comfortably without setting the temperature too low.\u003c\/p\u003e\n\u003cp\u003eA few habits help too. Close the blinds on the sunny side during the day, and let the heat pump hold a steady set point rather than turning it off in the morning and restarting it at full power in the evening. A room under the roof that has heated up all day stores heat in its walls and ceiling; it is easier to keep it cool than to cool it all at once at bedtime.\u003c\/p\u003e\n\u003ch3\u003eWhere to place the head in a room under the eaves\u003c\/h3\u003e\n\u003cp\u003eUpstairs bedrooms often have low walls, sloped ceilings or dormers. The wall head must be installed on a wall high enough for the airflow to cover the room without aiming directly at the bed. We favour an interior wall or a gable wall, with enough clearance above the unit for air return. The louvres are then set upward in cooling, so the cool air settles naturally throughout the room.\u003c\/p\u003e\n\u003ch3\u003eWinter, certified figures\u003c\/h3\u003e\n\u003cp\u003eThe same bedroom is often cold in winter. The certificate lists \u003cstrong\u003e9,500 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), about 106% of nominal capacity, with a \u003cstrong\u003eCOP of 2.53\u003c\/strong\u003e, and \u003cstrong\u003e10,600 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), about 118%, with a \u003cstrong\u003eCOP of 2.00\u003c\/strong\u003e. The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eIn practice, at these temperatures the heat pump delivers at least as much heat as its nominal capacity, which makes it a true primary heat source for a well-insulated bedroom for most of the winter. The existing baseboard can stay in place as backup, set a few degrees below the set point. The ENERGY STAR \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e confirms that the pairing was evaluated for cold winters.\u003c\/p\u003e\n\u003ch3\u003eThe technology: inverter and R-410A\u003c\/h3\u003e\n\u003cp\u003eA \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e moves heat: in winter, it draws it from the outdoor air and delivers it to the bedroom; in summer, it does the reverse. \u003cstrong\u003eInverter\u003c\/strong\u003e technology lets the compressor change speed instead of running all-or-nothing, which stabilizes the temperature and reduces consumption. The circuit uses \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant, proven over many years and well known to refrigeration technicians.\u003c\/p\u003e\n\u003cp\u003eIn practical terms, R-410A means straightforward service: technicians have the tools, procedures and common parts for this refrigerant, which makes maintenance and any repairs easier throughout the life of the unit.\u003c\/p\u003e\n\u003ch3\u003eWhat 28.1 SEER2 and 11.5 HSPF2 are worth\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSEER2 of 28.1\u003c\/strong\u003e: seasonal cooling efficiency.

We also choose with you the wall for the head and the location of the outdoor unit, taking into account the line route from the upper floor.\u003c\/p\u003e\n\u003cp\u003eWhen the house has several upstairs bedrooms, we discuss it frankly: a head in one bedroom will not cool the neighbouring rooms whose doors stay closed. Depending on the case, we present a head per bedroom or a multi-zone solution, and you choose knowing the trade-offs.\u003c\/p\u003e\n\u003ch3\u003eLines, drain and outdoor unit\u003c\/h3\u003e\n\u003cp\u003eFrom an upper floor, the \u003cstrong\u003erefrigerant lines\u003c\/strong\u003e, the communication cable and the drain exit through a single opening, sealed on both sides, then run down the exterior wall in a line cover that gives a clean, protected route. The drain follows a continuous slope to the ground, away from doors and walkways. The outdoor unit goes on a ground or wall stand, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, away from bedroom windows, including the neighbours'.\u003c\/p\u003e\n\u003ch3\u003eElectrical, commissioning and maintenance\u003c\/h3\u003e\n\u003cp\u003eThe system needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e: we check the panel capacity during the visit. At \u003cstrong\u003ecommissioning\u003c\/strong\u003e, the circuit is evacuated and checked for tightness, then we test both modes and drain flow. After that, rinse the indoor filters every two weeks in season, keep the outdoor unit clear of snow and leaves, and plan annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e of the coils, drain and electrical connections.
