At -8 °C, the certificate distinguishes between the nominal capacity of 11,100 BTU\/h, achieved with a COP of 2.80, and a maximum capacity of 21,447 BTU\/h. The inverter compressor therefore has plenty of reserve when the home requires more heat.\u003c\/p\u003e\u003ch3\u003eHeating a shared-wall ground floor\u003c\/h3\u003e\u003cp\u003eWith only one exterior wall on the sides, or none in a central townhouse unit, a shared-wall ground floor loses most of its heat through the front of the home, the rear patio door, and the roof. A wall-mounted unit positioned to blow along the length of the home works well in this type of space. The upstairs bedrooms generally remain heated by their baseboards: air from a wall-mounted unit does not move well up a closed staircase. If the upper floor also needs air conditioning, we can discuss adding a second unit or using a multi-zone solution.\u003c\/p\u003e\u003cp\u003eThe maximum airflow of \u003cstrong\u003e531 CFM\u003c\/strong\u003e, along with the 382 and 459 CFM settings, makes it possible to adjust air circulation according to the season. The \u003cstrong\u003eFollow Me\u003c\/strong\u003e function measures the temperature at the remote control, which is useful when the unit is installed away from the seating area.\u003c\/p\u003e\u003ch3\u003eSummer in a townhouse\u003c\/h3\u003e\u003cp\u003eIn cooling mode, the certified range is 5,732 to 20,226 BTU\/h, with a seasonal efficiency rating of 22.0 SEER2. The \u003cstrong\u003eECO\/GEAR\u003c\/strong\u003e function reduces consumption in cooling mode, while the \u003cstrong\u003eGentle\u003c\/strong\u003e function redirects the airflow when it becomes too direct.\u003c\/p\u003e\u003ch3\u003eThe $1,332 LogisVert rebate\u003c\/h3\u003e\u003cp\u003eThe system has \u003cstrong\u003eENERGY STAR ID 2410688\u003c\/strong\u003e and qualifies for a \u003cstrong\u003e$1,332\u003c\/strong\u003e rebate for owners of existing homes, according to the list in effect on the installation date. An enhanced rebate may apply in certain multi-unit buildings. We confirm eligibility before signing and prepare the detailed invoice and required model numbers.\u003c\/p\u003e\u003ch2\u003eNarrow lot, close neighbours: planning the installation\u003c\/h2\u003e\u003cp\u003eSemi-detached homes and townhouses create specific placement constraints.

In a narrow yard, we look for a location that meets the manufacturer's clearance requirements, remains above the snow line, and is away from bedroom windows, both yours and your neighbour's. Some municipalities also regulate the placement of outdoor units; we check the rules for your address in \u003cstrong\u003eMontreal\u003c\/strong\u003e, \u003cstrong\u003eLaval\u003c\/strong\u003e, or \u003cstrong\u003eLongueuil\u003c\/strong\u003e. At this weight, a ground stand on a stable base is often the best option. The base pan heater and Golden Fin anti-corrosion coating come standard, and DuraStar recommends keeping the unit powered continuously at 0 °C and below.\u003c\/p\u003e\u003ch3\u003eLong lines to reach the backyard\u003c\/h3\u003e\u003cp\u003eThe refrigerant lines are \u003cstrong\u003e1\/4 and 1\/2 inch\u003c\/strong\u003e, precharged for 25 feet, with a maximum length of \u003cstrong\u003e98 feet\u003c\/strong\u003e and a maximum elevation difference of \u003cstrong\u003e66 feet\u003c\/strong\u003e. Beyond the factory charge, 0.16 ounces of refrigerant is added per foot. This allowance makes it possible to place the indoor unit on the most suitable ground-floor wall and the condenser in the backyard. Our installations are fully exposed, with no work inside the walls, and a finished line-set cover can be added.\u003c\/p\u003e\u003ch3\u003eThe indoor unit\u003c\/h3\u003e\u003cp\u003eThe wall-mounted unit measures \u003cstrong\u003e42.64 x 9.61 x 13.23 inches\u003c\/strong\u003e and weighs 29.5 pounds. With this system, its sound level ranges from \u003cstrong\u003e25 to 46 dB(A)\u003c\/strong\u003e. The vertical louver oscillates automatically; the horizontal direction is adjusted manually. The remote control also offers \u003cstrong\u003eSleep\u003c\/strong\u003e, \u003cstrong\u003eTurbo\u003c\/strong\u003e, \u003cstrong\u003eSilence\u003c\/strong\u003e, the \u003cstrong\u003eClean\u003c\/strong\u003e function, a timer, and 8 °C freeze protection. The unit displays an alert code in the event of a refrigerant leak. Wi-Fi is not built in; DuraStar states that its indoor units are compatible with the DR24VINT2 24 V interface, which allows a third-party Wi-Fi thermostat to be connected.\u003c\/p\u003e\u003ch3\u003eElectrical requirements\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003e208-230 V\u003c\/strong\u003e power supply, \u003cstrong\u003e20 A MCA\u003c\/strong\u003e, and a \u003cstrong\u003e25 A breaker\u003c\/strong\u003e on a dedicated circuit.
