What is missing is efficient air conditioning and a way to reduce energy bills during the milder months. The \u003cstrong\u003eDURASTAR Standard Wall-Mounted Heat Pump | 18,000 BTU - R454B\u003c\/strong\u003e is built for this role. Its seasonal cooling efficiency reaches \u003cstrong\u003e24.0 SEER2\u003c\/strong\u003e, above the Sirius Heat 18,000 BTU's 21.7 SEER2, and its certified cooling range goes down to \u003cstrong\u003e3,600 BTU\/h\u003c\/strong\u003e, compared with 8,400 BTU\/h for its Sirius equivalent.\u003c\/p\u003e\u003cp\u003eIts other certified ratings are \u003cstrong\u003e13.5 EER2\u003c\/strong\u003e and \u003cstrong\u003e11.1 HSPF2\u003c\/strong\u003e.

The room is cool, but the air still feels heavy. With a range of \u003cstrong\u003e3,600 to 20,000 BTU\/h\u003c\/strong\u003e, this system can run for long periods at low speed: the coil stays cold, moisture condenses, and the air becomes more comfortable at the same temperature. The \u003cstrong\u003eDRY\u003c\/strong\u003e mode enhances this effect when humidity is the main source of discomfort.\u003c\/p\u003e\u003cp\u003eDuring heat waves, the capacity reserve up to 20,000 BTU\/h helps remove the accumulated heat from a west-facing room. The \u003cstrong\u003eECO\/GEAR\u003c\/strong\u003e function can then limit cooling consumption.\u003c\/p\u003e\u003ch3\u003eEfficient supplemental heating\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAt \u003cstrong\u003e8 °C\u003c\/strong\u003e: 18,000 BTU\/h, range of 7,600 to 22,000 BTU\/h, \u003cstrong\u003eCOP of 3.80\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-8 °C\u003c\/strong\u003e: \u003cstrong\u003e15,000 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 2.56\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-15 °C\u003c\/strong\u003e: \u003cstrong\u003e13,000 BTU\/h\u003c\/strong\u003e, \u003cstrong\u003eCOP of 2.35\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAt \u003cstrong\u003e-25 °C\u003c\/strong\u003e: up to \u003cstrong\u003e8,200 BTU\/h\u003c\/strong\u003e, COP of 1.70\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThese values come from certificate \u003cstrong\u003eAHRI 215359283\u003c\/strong\u003e, published by NEEP. In fall and spring, a COP of 3.80 means nearly four units of heat for one unit of electricity. In the middle of winter, the unit continues to heat efficiently, while the existing system takes over when demand exceeds its capacity or below -25 °C, its heating operating limit. Its HSPF2 rating of 11.1 also exceeds that of the Sirius Heat 18,000 BTU, which instead focuses on capacity in extreme cold.\u003c\/p\u003e\u003ch3\u003eCooling the bedroom level\u003c\/h3\u003e\u003cp\u003eA common request is to cool an entire bedroom level with a single unit. An 18,000 BTU unit installed in the hallway or on the landing can do so when the doors remain open and the rooms are nearby. Closed or distant bedrooms will receive less air; in that case, we discuss a second unit or a multi-zone system. The maximum airflow of \u003cstrong\u003e759 CFM\u003c\/strong\u003e helps project air farther, while the lower settings of \u003cstrong\u003e371, 441, and 500 CFM\u003c\/strong\u003e keep operation quiet at night.\u003c\/p\u003e\u003ch3\u003eLogisVert: $1,800\u003c\/h3\u003e\u003cp\u003eThe system carries \u003cstrong\u003eENERGY STAR ID 3621178\u003c\/strong\u003e and qualifies for a \u003cstrong\u003e$1,800 rebate\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

We secure it to the framing, high enough to distribute air properly, with sufficient drainage slope for condensate, which is plentiful in summer. The vertical louver oscillates automatically; the lateral direction is adjusted manually during commissioning.

Beyond the factory charge, we add 0.16 ounces of refrigerant per foot. This elevation difference can, for example, connect an indoor unit on the second floor to a ground-mounted condenser.
