Powered by \u003cstrong\u003e115 V\u003c\/strong\u003e, it is the larger of the brand's two 115 V wall-mounted models. Its role is clear: efficiently cool a living room or bedroom, then reduce the use of baseboard heaters during much of the winter.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e20.0 SEER2\u003c\/strong\u003e, \u003cstrong\u003e10.5 EER2\u003c\/strong\u003e, and \u003cstrong\u003e9.5 HSPF2\u003c\/strong\u003e. It heats down to \u003cstrong\u003e-20 °C\u003c\/strong\u003e and cools up to 50 °C. This system is not ENERGY STAR certified and does not appear on Hydro-Québec's LogisVert list, so the subsidy indicated on the product sheet is $0.\u003c\/p\u003e\u003ch3\u003eCertified figures, presented plainly\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCooling: \u003cstrong\u003e12,000 BTU\/h\u003c\/strong\u003e, range from 2,000 to 13,100 BTU\/h\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e8 °C\u003c\/strong\u003e: 12,000 BTU\/h, range from 3,100 to 13,800 BTU\/h, COP of 3.41\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-8 °C\u003c\/strong\u003e: \u003cstrong\u003e10,000 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 2.34\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-15 °C\u003c\/strong\u003e: \u003cstrong\u003e9,000 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 1.79\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-20 °C\u003c\/strong\u003e: up to \u003cstrong\u003e6,100 BTU\/h\u003c\/strong\u003e, COP of 1.52\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThese values come from certificate \u003cstrong\u003eAHRI 217727839\u003c\/strong\u003e, published by NEEP. The manufacturer's commercial product sheet lists some different values; we always display those from the certificate. At -8 °C, the unit produces more than twice the heat of a baseboard heater for the same energy consumption.\u003c\/p\u003e\u003ch3\u003e9,000 or 12,000 BTU at 115 V\u003c\/h3\u003e\u003cp\u003eThe two 115 V models share the same indoor unit size and the same operating limits. The 12,000 BTU model stands out for its capacity: 9,000 BTU\/h at -15 °C, compared with 7,300 BTU\/h for the 9,000 BTU model, and a nominal cooling capacity of 12,000 BTU\/h. Its seasonal cooling efficiency is also slightly better, at 20.0 SEER2 versus 19.0. In return, its outdoor unit is heavier, at 59.5 pounds, and its EER2 rating, which measures efficiency at 35 °C, is 10.5 versus 11.7. For a living room or bedroom that receives a lot of sunlight, the 12,000 BTU model is generally the safer choice.\u003c\/p\u003e\u003ch3\u003eThe heat pump's role in winter\u003c\/h3\u003e\u003cp\u003eIn the fall and spring, with a COP of 3.41 at 8 °C, the heat pump warms the room at low cost. In cold weather, it continues to provide a significant share of the heat while the baseboard heaters, set a few degrees below its setpoint, supplement it as needed. Below -20 °C, it stops heating, as specified by the manufacturer; the baseboard heaters then provide all the heating. This model is therefore not designed to replace a home's heating system, but to reduce its operating cost.\u003c\/p\u003e\u003cp\u003eIf the subsidy or heating in very cold weather is a priority, the 208-230 V models in the DuraStar lineup are better suited. The R-454B Standard 12,000 BTU model, for example, appears on the LogisVert list with a $1,248 incentive and heats down to -25 °C.\u003c\/p\u003e\u003ch2\u003eSuccessfully Installing a 115 V System in a Home: Location, Power Supply, and Maintenance\u003c\/h2\u003e\u003cp\u003eA 115 V unit must be installed with the same care as a 208-230 V model. Here are the points we check.\u003c\/p\u003e\u003ch3\u003eThe indoor unit\u003c\/h3\u003e\u003cp\u003eThe wall-mounted unit measures \u003cstrong\u003e31.93 x 7.95 x 11.50 inches\u003c\/strong\u003e and weighs 19.8 pounds. Its sound level ranges from \u003cstrong\u003e28 dB(A)\u003c\/strong\u003e at the lowest setting to \u003cstrong\u003e45 dB(A)\u003c\/strong\u003e at the Turbo setting, with a maximum airflow of \u003cstrong\u003e342 CFM\u003c\/strong\u003e. The louvers automatically oscillate vertically and horizontally, and DuraStar indicates up to 72 airflow angles. The \u003cstrong\u003eI FEEL\u003c\/strong\u003e function measures the temperature at the remote control, right where you are. It also includes \u003cstrong\u003eECO\u003c\/strong\u003e cooling mode, \u003cstrong\u003eSleep\u003c\/strong\u003e, \u003cstrong\u003eTurbo\u003c\/strong\u003e, \u003cstrong\u003eMute\u003c\/strong\u003e, a timer, the \u003cstrong\u003eSelf-Clean\u003c\/strong\u003e function for the indoor coil, and an 8 °C heating mode that protects the room from freezing during an absence. Wi-Fi is not available on this model.\u003c\/p\u003e\u003ch3\u003eThe outdoor unit on a balcony\u003c\/h3\u003e\u003cp\u003eThe condenser measures \u003cstrong\u003e28.03 x 9.21 x 19.61 inches\u003c\/strong\u003e, weighs 59.5 pounds, and produces \u003cstrong\u003e55 dB(A)\u003c\/strong\u003e. Its shallow depth makes installation on a balcony or on a wall bracket anchored to the structure easier. Where snow is an issue, DuraStar's installation manual requires placing it higher than the average snow accumulation, with a minimum clearance of 18 inches, and keeping the drain hose as vertical as possible in cold weather. The documentation for this system does not mention a base pan heater; drainage of defrost water is therefore a point we pay close attention to. The coils are protected by a Blue Fin anti-corrosion coating. In a condominium, we provide the condominium association with the unit's dimensions, weight, and sound level.\u003c\/p\u003e\u003ch3\u003eThe refrigerant lines\u003c\/h3\u003e\u003cp\u003eThe lines are \u003cstrong\u003e1\/4 and 3\/8 inch\u003c\/strong\u003e, precharged for 25 feet. Their length must be between 10 and \u003cstrong\u003e49 feet\u003c\/strong\u003e, with a maximum height difference of \u003cstrong\u003e33 feet\u003c\/strong\u003e and an additional 0.11 ounce of refrigerant per foot beyond the precharge. The two units must therefore remain relatively close together, which we plan from the outset during the site visit. The installation is entirely exposed, with no need to open an interior wall, and a finished line set cover can be added.\u003c\/p\u003e\u003ch3\u003eElectrical supply\u003c\/h3\u003e\u003cp\u003eThe system operates on \u003cstrong\u003e115 V\u003c\/strong\u003e single-phase power, across a range of 105 to 125 V, with an \u003cstrong\u003eMCA of 17 A\u003c\/strong\u003e and a \u003cstrong\u003erecommended 25 A circuit breaker\u003c\/strong\u003e, according to the manufacturer's product sheet. It must be connected to a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e that complies with the applicable code, without sharing its power supply with other appliances. We check the service capacity and available panel space during the assessment.\u003c\/p\u003e\u003ch3\u003eR-454B refrigerant\u003c\/h3\u003e\u003cp\u003eThis system uses \u003cstrong\u003eR-454B\u003c\/strong\u003e, a next-generation A2L refrigerant with a significantly lower global warming potential than R-410A.
