Everything sits in one outdoor cabinet (compressor, coils and fan), connected to the building's ducts. The unit is all-electric and handles heating in winter as well as air conditioning in summer. At AirGreen, we install this model in Montreal, Laval, Longueuil, on the North Shore and on the South Shore, and we always start with the same step: confirming that 2 tons is the right capacity for your building.\u003c\/p\u003e\n\u003cp\u003eRated capacity is 24,000 BTU\/h. The unit is \u003cstrong\u003eENERGY STAR Cold Climate certified\u003c\/strong\u003e, posts a \u003cstrong\u003eSEER2 of 18.0\u003c\/strong\u003e and delivers \u003cstrong\u003eheating down to -30 °C\u003c\/strong\u003e outdoors. Before we talk about efficiency, though, let's talk about sizing, because a unit that is too big for the building runs poorly, whatever its spec sheet says.\u003c\/p\u003e\n\u003ch3\u003eThe buildings this size is meant for\u003c\/h3\u003e\n\u003cp\u003eThe 2 ton fits when the heating and cooling load stays modest and all the air travels through one duct system. Here are the situations we often meet in the field:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall business:\u003c\/strong\u003e a shop, a hair salon, a service counter or a café whose sales floor is served by a single duct system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOffice:\u003c\/strong\u003e a professional practice, an agency or a small administrative office where you want a steady temperature during business hours, winter and summer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge home:\u003c\/strong\u003e a house whose floors are tied to the same duct system and that has a suitable outdoor spot for a packaged cabinet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixed-use space:\u003c\/strong\u003e a workshop with a reception area, a studio or an adjoining meeting room, tied to the same air distribution.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNo simple rule ties floor area to capacity. Insulation, windows, orientation, the number of occupants, the equipment that gives off heat and the building's air tightness all weigh just as much in the calculation. That is why we assess the building on site before recommending a size, rather than relying on a square-foot estimate.\u003c\/p\u003e\n\u003ch3\u003eWhy not go bigger \"just to be safe\"\u003c\/h3\u003e\n\u003cp\u003eThe instinct makes sense: pick a bigger unit to be sure of having enough heat in January. In practice, an oversized unit creates other drawbacks, and summer is when you notice them most.\u003c\/p\u003e\n\u003ch4\u003eCycles that are too short\u003c\/h4\u003e\n\u003cp\u003eWhen capacity clearly exceeds the need, the unit reaches the setpoint very quickly, shuts down, then restarts shortly after. These short cycles multiply compressor starts, create temperature gaps from one room to the next and move the air in bursts. Gree's \u003cstrong\u003eDC Inverter\u003c\/strong\u003e technology lets the compressor slow down when demand falls, but it is on a unit whose capacity matches the building that it makes full sense: it can then run for long stretches at moderate speed instead of stopping and starting again endlessly.\u003c\/p\u003e\n\u003ch4\u003eDehumidification through the summer\u003c\/h4\u003e\n\u003cp\u003eIn cooling, the coil also pulls moisture out of the air, but only if it runs long enough for the water to condense and drain. An oversized unit cools the air in a few minutes then shuts off: the temperature on the display is reached, but the air stays humid and the room feels clammy. Through the hot, humid days Montreal and Laval get in July, a properly sized unit runs longer and dries the indoor air better. Your customers, your employees or your family feel it right away.\u003c\/p\u003e\n\u003ch4\u003eAn investment matched to the real need\u003c\/h4\u003e\n\u003cp\u003eChoosing the right capacity also means not paying for tons that will never be used, then living with their drawbacks for years. If our assessment shows that your building needs more, we will tell you plainly and we will propose the next size up in the same line.

The 3, 4 and 5 ton units certify an EER2 of 11.2 and an HSPF2 of 8.5 or 8.3. The \u003cstrong\u003eSEER2 of 18.0\u003c\/strong\u003e, for its part, is the same across the whole line.

An electric baseboard, for its part, turns electricity into heat without drawing anything from the outdoor air.\u003c\/p\u003e\n\u003ch3\u003eThe certified capacities, and how to read them\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCooling at 35 °C: 24,000 BTU\/h.\u003c\/li\u003e\n\u003cli\u003eHeating at 8.3 °C: 24,000 BTU\/h.\u003c\/li\u003e\n\u003cli\u003eHeating at -8.3 °C (17 °F): 15,500 BTU\/h, the certified rated capacity.\u003c\/li\u003e\n\u003cli\u003eHeating at -15 °C (5 °F): 29,000 BTU\/h, measured at maximum compressor speed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe value at -15 °C is higher than the one at -8.3 °C, which can be surprising. The two figures do not measure the same thing. The capacity at -8.3 °C is the certified rated capacity; the one at -15 °C is measured at maximum compressor speed, as the criterion for the \u003cstrong\u003eENERGY STAR Cold Climate\u003c\/strong\u003e designation requires.
