Under the roof, an attic bedroom becomes a furnace in July and cools quickly in January.

At -8 °C, the unit still delivers more than 90% of its nominal capacity. This is the temperature around which a significant part of winter unfolds in southern Quebec.\u003c\/p\u003e\u003ch3\u003eSummer under the roof\u003c\/h3\u003e\u003cp\u003eA finished attic room accumulates heat from the roof all day. In the late afternoon, the cooling load can far exceed what the floor area suggests. With a certified capacity of 24,000 BTU\/h, a reserve of up to 27,000 BTU\/h, and an EER2 rating of 13.0, which measures efficiency at 35 °C, the system stays in control during heat waves. The \u003cstrong\u003eECO\/GEAR\u003c\/strong\u003e function can then reduce cooling consumption as the heat subsides.\u003c\/p\u003e\u003ch3\u003eWinter: a clear backup-heating plan\u003c\/h3\u003e\u003cp\u003eThe Standard 24,000 BTU heats efficiently down to -15 °C, with a COP of 2.15 at that temperature. Its capacity then gradually decreases, and it stops heating below -25 °C, its operating limit. In an attic room, often heated only by baseboard heaters, we therefore check that they are working and set a few degrees below the heat pump's setpoint. They will activate only during very cold weather.\u003c\/p\u003e\u003cp\u003eIf you want to minimize baseboard use, the Sirius Heat 24,000 BTU with R-454B maintains 24,000 BTU\/h at -15 °C and heats down to -30 °C. The Standard, however, offers better seasonal cooling efficiency, at 23.5 SEER2 versus 22.3, and a better COP at -15 °C. We compare the two with you based on the room's actual use.\u003c\/p\u003e\u003ch3\u003eThe $2,688 LogisVert rebate\u003c\/h3\u003e\u003cp\u003eThis system is listed under \u003cstrong\u003eENERGY STAR ID 3621185\u003c\/strong\u003e, with a \u003cstrong\u003e$2,688\u003c\/strong\u003e rebate for the owner of an existing home, according to the list in effect on the installation date.

We address them before installation rather than during the installation itself.\u003c\/p\u003e\u003ch3\u003eFinding the right wall\u003c\/h3\u003e\u003cp\u003eThe wall-mounted unit measures \u003cstrong\u003e42.60 x 9.21 x 13.27 inches\u003c\/strong\u003e and weighs 30.9 pounds. Under a sloped ceiling, there must be a sufficiently tall section of vertical wall to accommodate the unit and leave clearance above it for air intake. In a glass-walled room, available solid wall space can be limited; we choose the wall that allows the airflow to sweep across the glazed surface without blowing directly onto occupants. The vertical louver oscillates automatically, while the lateral direction is adjusted manually during commissioning.\u003c\/p\u003e\u003ch3\u003eCondensate\u003c\/h3\u003e\u003cp\u003eIn cooling mode, a unit of this size removes a great deal of water from the air. In an attic, the drain must be planned carefully: gravity drainage through the exterior wall whenever possible; otherwise, a condensate pump, always specified in the quote.\u003c\/p\u003e\u003ch3\u003eThe outdoor unit and lines\u003c\/h3\u003e\u003cp\u003eThe condenser measures \u003cstrong\u003e37.24 x 16.14 x 31.89 inches\u003c\/strong\u003e, weighs \u003cstrong\u003e122.1 pounds\u003c\/strong\u003e, and produces \u003cstrong\u003e60 dB(A)\u003c\/strong\u003e. We install it on the ground or on a support anchored to the structure, above the snow line. The refrigerant lines are \u003cstrong\u003e3\/8 and 5\/8 inch\u003c\/strong\u003e, precharged for 25 feet, with a maximum length of \u003cstrong\u003e164 feet\u003c\/strong\u003e and a maximum elevation difference of \u003cstrong\u003e82 feet\u003c\/strong\u003e, more than enough to connect an attic to the ground. Beyond the precharge, we add 0.32 ounces of refrigerant per foot. The installation remains fully exposed, and a finished line-set cover can protect the lines along the facade.\u003c\/p\u003e\u003ch3\u003eElectrical requirements\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003e208-230 V\u003c\/strong\u003e power supply, \u003cstrong\u003e24 A MCA\u003c\/strong\u003e, and a \u003cstrong\u003e25 A breaker\u003c\/strong\u003e on a dedicated circuit.

After a shutdown, the compressor waits three minutes before restarting. Below -25 °C, the heating shutdown is specified by the manufacturer. A light hissing sound or plastic cracking does not indicate a malfunction. However, an indoor water leak, a persistent error code, or a tripped breaker requires a service visit.\u003c\/p\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cp\u003eClean the \u003cstrong\u003eindoor filters\u003c\/strong\u003e every two weeks during the season, clear snow from the condenser, and schedule annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e.
