Window AC / September 13, 2018 / Marphisa Babin
If there is no central hot air heating then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed then do not force the issue and go another option. Ductless split type air conditioning may be your best option.
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.
If you already have a window air conditioning unit and you have noticed recently that it seems to be louder there are few steps you should take. Check to see if the unit is vibrating on the windowsill. It may need to be re-tightened on its shelf. The side panels might also be loose. Inspect those to see if they need tightening. If the unit seems to be vibrating more than normal consider sliding a piece of wood under the unit to secure it.
