Proper sizing remains essential. At AirGreen, we never recommend a unit solely because its capacity seems impressive on paper. Instead, we analyze the entire building: surface area, ceiling height, insulation, solar orientation, number of occupants, type of use, internal loads, windows, doors, existing ventilation, and ceiling configuration.\u003c\/p\u003e\n\u003cp data-start=\"3934\" data-end=\"4335\"\u003eA commercial space with a large glass facade in \u003cstrong data-start=\"3982\" data-end=\"3998\"\u003eBoucherville\u003c\/strong\u003e may require a very different approach than an interior office in \u003cstrong data-start=\"4066\" data-end=\"4075\"\u003eLaval\u003c\/strong\u003e or a common room in a building in \u003cstrong data-start=\"4118\" data-end=\"4131\"\u003eLongueuil\u003c\/strong\u003e.
