That is the use case of this page, and it starts with a clarification: the GENERAL AIRSTAGE RLB 24,000 BTU is the same machine as the Fujitsu AIRSTAGE RLB 24,000 BTU. Same indoor unit \u003cstrong\u003eASU24RLB\u003c\/strong\u003e, same outdoor unit \u003cstrong\u003eAOU24RLB\u003c\/strong\u003e, same AHRI certificate 7940753, same values published by the manufacturer, same warranty. Fujitsu General Limited became GENERAL Inc. on January 1, 2026; only the name printed on the unit, the carton and the invoice changes.\u003c\/p\u003e\n\n\u003cp\u003eThe RLB is an \u003cstrong\u003eair conditioning\u003c\/strong\u003e model first. It heats too, with heating guaranteed down to −15 °C, which covers fall, spring and the mild weeks of winter, but we will not present it as a primary heating system for January. This page explains what it does well, what we do not promise, and how we install it on the upper floor of a South Shore house.\u003c\/p\u003e\n\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\n\u003cp\u003eWhat changes for you fits in one line: the logo. Fujitsu General was acquired in August 2025 by Paloma Rheem Holdings, owner of Rheem since 1988, and on January 1, 2026, Fujitsu General Limited became GENERAL Inc. The head office and the research and development centre are still in Kawasaki, Japan; the factories, the AIRSTAGE products, the model numbers and the warranty program are unchanged. The name is not a marketing invention: GENERAL has been in use as a trademark since 1946, and the company, founded in 1936, marks the 90th anniversary of its founding in 2026. In Canada, Rheem Canada has handled sales since February 2026; we continue to buy from Groupe Master, our distributor.\u003c\/p\u003e\n\n\u003cp\u003eWhile the Fujitsu brand is phased out, the same mini split is sold under both names and may arrive with either logo. We publish both pages so that you can check that it is indeed the same unit, and the table below lines up the two versions, value by value.\u003c\/p\u003e\n\n\u003ctable class=\"tp-compare\"

With 24,000 BTU of cooling capacity, the RLB has the size for that entire floor, on one condition we check on site: the wall unit must be placed where the cold air can spread, meaning in the hallway or at the top of the stairs, so that the air settles by itself into the bedrooms whose doors stay open. A unit installed in a closed bedroom cools that bedroom and nothing else. The \u003cstrong\u003eSEER2\u003c\/strong\u003e of 18.0 published by the manufacturer measures cooling efficiency over a whole season; the higher it is, the less each hour of coolness costs on the Hydro-Québec bill. While cooling, the unit also pulls humidity out of the air, and that is often what makes a July night upstairs sleepable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHeating in the shoulder seasons, said plainly.\u003c\/strong\u003e The manufacturer guarantees the RLB's heating down to −15 °C. Concretely, that means that from October to the end of November and from mid-March to May, the \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e can keep the upper floor warm on its own, and that it takes over during winter thaws. When the thermometer drops below −15 °C, your current system, furnace or baseboards, takes the work back. For this model, we quote only the values published by the manufacturer: a SEER2 of 18.0 and heating guaranteed down to −15 °C. It is not ENERGY STAR certified, it is not rated for cold climates and it is not on the list of equipment eligible for Hydro-Québec's LogisVert program; so we will promise you no grant for it. That is precisely what makes it a sensible choice where coolness comes first and the primary heating already exists.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDiscreet on the wall and in the yard.\u003c\/strong\u003e The indoor unit measures 39.25 in wide, 9 in deep and 12.63 in high: it fits above a hallway door or at the top of a staircase without overwhelming the wall. It runs between 31 and 47 dB(A) depending on fan speed; at low speed, in a hallway at night, you do not hear it from the bedrooms. The outdoor unit is about 31 in wide and 24.5 in high, a compact format for the side of a Châteauguay house, and it runs at 54 dB(A), a figure we take into account when choosing its location relative to bedroom windows.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe upstairs installation.\u003c\/strong\u003e A mini split needs no ductwork: the wall unit, the outdoor unit, and between the two a refrigerant line, a cable and a drain that pass through a single hole. Here is what our refrigeration technicians settle for an upstairs installation:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003ePlacing the unit\u003c\/strong\u003e: hallway, landing or master bedroom depending on what you want to cool first, on an exterior wall when possible to shorten the route.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eThe refrigerant line\u003c\/strong\u003e: insulated 1\/4 and 1\/2 in copper, the format for this model, running down the exterior wall in a line cover to the unit on the ground or on its bracket.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDrainage\u003c\/strong\u003e: from the upper floor, condensate drains easily by gravity, which in most cases avoids the condensate pump.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eThe outdoor unit\u003c\/strong\u003e: on a wall bracket or a ground base, above the snow, with clearance for air and for defrost water.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eElectrical\u003c\/strong\u003e: a dedicated 208\/230 V circuit, sized from the nameplate and connected by a licensed electrician.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWi-Fi\u003c\/strong\u003e: optional on this model; useful to start the upstairs cooling before coming home on a heat-wave evening.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eMaintenance and filters.\u003c\/strong\u003e The indoor filters pull out by hand and rinse under warm water; in cooling season, they hold the upper floor's dust and deserve a regular rinse to keep the airflow. In the fall, a look at the outdoor unit to remove leaves, and in winter, a few shovelfuls after snowfalls. Once a year, a refrigeration technician checks the \u003cstrong\u003eR-410A refrigerant\u003c\/strong\u003e charge, cleans the coil and the drain pan and checks the flow. The warranty is identical under both names: 12 years on the compressor, 12 years on parts, 6 years on labour, with an extended warranty possible.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWho this model is for.\u003c\/strong\u003e The two-storey house in Châteauguay or Beauharnois whose primary heating is already settled, a furnace in the basement or baseboards in every room, and where what is missing is coolness upstairs in summer. The owner who wants a simple mini split, without functions they will never use, and who understands that the unit will heat in the shoulder seasons rather than in the heart of January. If you are looking instead for a heat pump that replaces the baseboards all winter, we will propose a cold-climate model from the AIRSTAGE range rather than this one, and we will tell you why during the visit.\u003c\/p\u003e\n\n\u003ch3\u003eFree quote in Châteauguay, Beauharnois and across the South Shore\u003c\/h3\u003e\n\n\u003cp\u003eCall us at 514 316-2973 or request your \u003cstrong\u003efree quote\u003c\/strong\u003e online.
