Window AC / August 26, 2018 / Denise Brisette
They are also easy to install unlike split air systems and central ac. Installing a window unit is an easy DIY job that can be tackled in an hour or so. Also because they are installed in a semi-permanent fashion you just set it and forget it. Unlike portable ac units which are often wheeled around from room to room a window unit is designed to stay put. In spite of all of these benefits however window units have one major drawback: the noise. These units are loud and different models can range from being moderately annoying to downright deafening.
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.
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.
