Window AC / August 24, 2018 / Aubrette Dumoulin
There are other bells and whistles that are available on units these days. These can include features like dehumidifiers to remove moisture from the air and antibacterial filters which can remove odors and bacteria. A final issue to consider if you are looking to buy window air conditioner is what sorts of energy saving features the unit might have. You may consider looking for a unit that has an Energy-Star rating. The EPA assigns an Energy-Star rating to air conditioners that meet certain standards for being cost-effective and guaranteeing energy savings. This can help keep your electricity bills and check even during the hottest days of summer.
Side panels fill the gaps on the sides. These are also very thin so most of the sleeve is uncovered and outside. This allows for placement of ventilation louvers on the sides and top allowing free movement of air. This is the primary difference between the two types. The wide availability of louver space allows the unit to move a lot of air and this means window units can be quite powerful up to 3 tons or 36000 BTU. So window A/Cs can be effective for very large rooms. In contrast a wall air conditioner sleeve is designed for a hole through the wall. Walls vary substantially in thickness.
A wall with simple sheet type siding may be only 6 inches thick whereas a brick or stone wall can be much thicker. So wall air conditioner sleeves have ventilation louvers only in the back to avoid louvers being covered by the wall edges. This limits the amount of ventilation space available in turn limiting how powerful the unit can be. Wall air conditioners generally dont get much over 14000 BTU depending on the brand. So are they interchangeable? This question usually arises when someone needs a lot of cooling power in a room without suitable windows for a window unit.
