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.

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.

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.

We do this work everywhere in Montreal, Laval, Longueuil, on the North Shore and on the South Shore.\u003c\/p\u003e\n\u003ch3\u003eFirst case: the old rooftop unit is reaching the end of its life\u003c\/h3\u003e\n\u003cp\u003eAn aging rooftop unit is quick to recognize: repairs one after another, unusual noise, uneven comfort from one end of the space to the other. When the building already has a duct system in good condition, replacing it with a packaged unit avoids opening up the ceilings and redoing the air distribution. The occupants find their grilles in the same place; only the unit changes.\u003c\/p\u003e\n\u003cp\u003eDuring the visit, we compare the existing location with the dimensions of the new cabinet, that is 44 × 35-7\/16 × 49-1\/4 in. (1,120 × 900 × 1,250 mm), and with its net weight of 523 lb. We also look at the connection of the supply and return ducts, the condition of the insulation and the tightness of the joints. Since the unit is all-electric, no fuel connection has to be planned.\u003c\/p\u003e\n\u003cp\u003eAnother advantage for small buildings: the supply is 208-230 V, single-phase, 60 Hz. A building with no three-phase service, like many multiplexes and neighbourhood commercial spaces, therefore does not have to have one installed to take the unit.\u003c\/p\u003e\n\u003ch3\u003eSecond case: moving off electric baseboards\u003c\/h3\u003e\n\u003cp\u003eBaseboards heat each room separately and provide no air conditioning.
