There may be no room for a double-pole breaker, an already heavily loaded service entrance, or a home where connecting to 208-230 V would require major work. The \u003cstrong\u003eDURASTAR Standard Wall-Mounted Heat Pump | 9,000 BTU 115V - R454B\u003c\/strong\u003e operates on a \u003cstrong\u003e115 V\u003c\/strong\u003e power supply. It therefore simplifies the electrical side of the project while providing air conditioning and effective supplemental heating.\u003c\/p\u003e\u003cp\u003eHowever, you should understand its limitations before choosing it. Its certified ratings are \u003cstrong\u003e19.0 SEER2\u003c\/strong\u003e, \u003cstrong\u003e11.7 EER2\u003c\/strong\u003e, and \u003cstrong\u003e9.5 HSPF2\u003c\/strong\u003e. It heats down to \u003cstrong\u003e-20 °C\u003c\/strong\u003e, is not ENERGY STAR certified, and is not listed on Hydro-Québec's LogisVert list, which is why the rebate shown on the product sheet is $0. We prefer to state this clearly from the outset.\u003c\/p\u003e\u003ch3\u003eCertified capacities\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCooling: \u003cstrong\u003e9,000 BTU\/h\u003c\/strong\u003e, range of 2,000 to 11,100 BTU\/h\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e8 °C\u003c\/strong\u003e: 10,000 BTU\/h, range of 2,500 to 12,500 BTU\/h, \u003cstrong\u003eCOP of 3.81\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-8 °C\u003c\/strong\u003e: \u003cstrong\u003e8,000 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 2.09\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-15 °C\u003c\/strong\u003e: \u003cstrong\u003e7,300 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 1.89\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-20 °C\u003c\/strong\u003e: up to \u003cstrong\u003e6,200 BTU\/h\u003c\/strong\u003e, COP of 1.47\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 217727837\u003c\/strong\u003e, published by NEEP. The COP of 3.81 at 8 °C shows that the unit is highly efficient in the fall and spring. In the middle of winter, it continues to produce approximately twice as much heat as a baseboard heater for the same amount of electricity, until the temperature reaches its operating limit.\u003c\/p\u003e\u003ch3\u003eThe right use: cooling first, supplemental heating\u003c\/h3\u003e\u003cp\u003eWe recommend this system for a bedroom, office, or small room where cooling is the priority and baseboard heaters already provide heating. From late fall to early spring, the heat pump handles most of the room's heating at a reduced cost. During very cold weather, the baseboard heaters remain on, set a few degrees below the heat pump's setpoint, and take over completely below -20 °C.\u003c\/p\u003e\u003cp\u003eIf you are looking for primary heating in very cold weather or a LogisVert rebate, a 208-230 V model from the DuraStar range would be more suitable. During our assessment, we specifically check whether adding a 208-230 V circuit is realistic in your home before recommending the 115 V option.\u003c\/p\u003e\u003ch3\u003eEvenly distributed comfort throughout the room\u003c\/h3\u003e\u003cp\u003eThe indoor unit measures \u003cstrong\u003e31.93 x 7.95 x 11.50 inches\u003c\/strong\u003e and weighs 19.8 pounds. Unlike the DuraStar 208-230 V wall-mounted units in our selection, it automatically oscillates vertically and horizontally, controlled by the remote. DuraStar indicates coverage of up to 72 discharge angles, helping air reach the corners of an irregularly shaped room. Its fan offers four speeds of \u003cstrong\u003e200, 235, 270, and 342 CFM\u003c\/strong\u003e, and its sound level ranges from \u003cstrong\u003e28 to 42 dB(A)\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eThe remote provides access to the \u003cstrong\u003eI FEEL\u003c\/strong\u003e function, which measures the temperature where the remote is located, as well as \u003cstrong\u003eECO\u003c\/strong\u003e mode, available in cooling, \u003cstrong\u003eSleep\u003c\/strong\u003e mode, which shuts off after ten hours, \u003cstrong\u003eTurbo\u003c\/strong\u003e and \u003cstrong\u003eMute\u003c\/strong\u003e modes, the timer, and the \u003cstrong\u003eSelf-Clean\u003c\/strong\u003e function. The latter briefly freezes and then defrosts the indoor coil to dislodge dust and deposits responsible for odors, in about thirty minutes; DuraStar suggests using it every three months. The 8 °C heating function keeps the room above freezing during an absence; it cancels automatically when the outdoor temperature reaches 18 °C. Wi-Fi is not available on this model.\u003c\/p\u003e\u003ch2\u003eInstalling a 115 V system properly: circuit, snow, and drainage\u003c\/h2\u003e\u003cp\u003eA simpler power supply does not mean an improvised installation. Here is what we plan for.\u003c\/p\u003e\u003ch3\u003eThe electrical circuit\u003c\/h3\u003e\u003cp\u003eThe system operates on \u003cstrong\u003e115 V\u003c\/strong\u003e single-phase power, within a range of 105 to 125 V. The manufacturer's specifications indicate an \u003cstrong\u003eMCA of 16 A\u003c\/strong\u003e and a \u003cstrong\u003erecommended 25 A breaker\u003c\/strong\u003e. The unit must not share its power supply with other appliances: it requires a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e installed according to the applicable code. We check your service capacity and the available panel space during the visit.\u003c\/p\u003e\u003ch3\u003eThe outdoor unit\u003c\/h3\u003e\u003cp\u003eThe condenser measures \u003cstrong\u003e28.03 x 9.21 x 19.61 inches\u003c\/strong\u003e, weighs 51.8 pounds, and produces \u003cstrong\u003e54 dB(A)\u003c\/strong\u003e. Its compact, lightweight design works well on a balcony or on a wall bracket anchored to the structure. DuraStar's installation manual requires the unit to be placed higher than the average snow accumulation in areas where it snows, with a minimum height of 18 inches. It also recommends keeping the drainage hose as vertical as possible in cold weather so that defrost water does not freeze in the hose. The documentation for this system does not mention a base-pan heater; we therefore pay particular attention to placement and drainage. The indoor and outdoor coils are protected by a Blue Fin anti-corrosion coating.\u003c\/p\u003e\u003ch3\u003eThe refrigerant lines\u003c\/h3\u003e\u003cp\u003eThe lines are \u003cstrong\u003e1\/4 and 3\/8 inch\u003c\/strong\u003e, pre-charged for 25 feet. The length must be at least 10 feet and no more than \u003cstrong\u003e49 feet\u003c\/strong\u003e, with a maximum elevation difference of \u003cstrong\u003e33 feet\u003c\/strong\u003e. Beyond the pre-charge length, add 0.11 ounces of refrigerant per foot. This shorter maximum length than that of the 208-230 V models means the two units must be installed closer together, which we plan during the visit. The installation remains entirely exposed, without opening the interior wall.\u003c\/p\u003e\u003ch3\u003eR-454B refrigerant\u003c\/h3\u003e\u003cp\u003eLike the brand's recent models, this system uses \u003cstrong\u003eR-454B\u003c\/strong\u003e, a next-generation A2L refrigerant with a significantly lower global warming potential than R-410A. Its handling follows the safety rules applicable to mildly flammable refrigerants.\u003c\/p\u003e\u003ch3\u003eWhat is normal\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe unit may take two to five minutes to start or restart: this is compressor protection.\u003c\/li\u003e\n\u003cli\u003eIn heating mode, a two- to ten-minute \u003cstrong\u003edefrost\u003c\/strong\u003e cycle may occur, with white vapor appearing when operation resumes.\u003c\/li\u003e\n\u003cli\u003eA slight refrigerant hiss and plastic cracking sounds are part of normal operation.\u003c\/li\u003e\n\u003cli\u003eBelow -20 °C, the heating shutdown corresponds to the manufacturer's specified limit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eA persistent error code, a tripped breaker, or water leaking from the indoor unit warrants shutting off the appliance and scheduling a service visit.\u003c\/p\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cp\u003eDuraStar recommends cleaning the \u003cstrong\u003eindoor filters\u003c\/strong\u003e every two weeks. Keep the condenser clear of snow and check that the drain flows freely in winter. Annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e completes these tasks: coil cleaning, drainage checks, and electrical connection inspections.\u003c\/p\u003e\u003ch3\u003eAirGreen, advice tailored to your building\u003c\/h3\u003e\u003cp\u003eAirGreen is a family-owned \u003cstrong\u003eMontreal\u003c\/strong\u003e company that has been installing wall-mounted heat pumps in \u003cstrong\u003eLaval\u003c\/strong\u003e, \u003cstrong\u003eLongueuil\u003c\/strong\u003e, the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e, and the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e for more than fifteen years.
