In some homes in \u003cstrong\u003eMontreal, Laval, Longueuil, the North Shore, and the South Shore\u003c\/strong\u003e, the challenge is not finding a heat pump with sufficient performance; it is finding \u003cstrong\u003ethe right indoor location\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eA large window sometimes occupies almost the entire upper portion of a wall. A cathedral ceiling can make a wall-mounted unit visually dominant. In a basement, available wall space may be interrupted by low windows, beams, or soffits. In other projects, the homeowner simply wants airflow delivered closer to the occupied area.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSENVILLE SENA-18HF-IFG\u003c\/strong\u003e, paired with the \u003cstrong\u003eSENA-18HF-OG\u003c\/strong\u003e outdoor unit, is specifically suited to this type of constraint. Senville’s documentation presents this family as a ductless heat pump with a \u003cstrong\u003efloor console\u003c\/strong\u003e, ENERGY STAR certified and capable of providing heating and cooling year-round. \u003cspan class=\"contents\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFor us at \u003cstrong\u003eAirGreen Heat Pumps, Air Conditioning \u0026amp; Heating\u003c\/strong\u003e, this model’s appeal therefore lies not only in its \u003cstrong\u003e18,000 BTU\u003c\/strong\u003e capacity.
