Window AC / August 26, 2018 / Denise Brisette
These extenders will fill the space between the unit and the edges of to keep air from leaking out. Youre now ready to open the window from the bottom pain and have your helper raise the A/C into position. Rest the A/C on the window sill and slide the extensions out to fill any gaps. Check the instructions provided with your A/C for the what the correct placement is for your specific appliance. Most air conditioning units should tilt outward to drain any condensation that may accumulate on it. Finally you will fasten the brackets and lower the window pain back to the top of your machine. Sometimes it is wise to fasten the upper window pane in place to avoid movement of your A/C.
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.
This will help you determine the amount of BTU s necessary to cool your room adequately. For example an 8000 BTU unit will cool a room up to about 350 square feet. Another thing to consider when buying a window unit is any special features that come with the unit. In particular most window units include louvers that let you direct airflow programmable timers so that you can set the unit to turn off or on when you wish and energy efficient features like multiple fan speeds. Many units also come standard with a remote control so that you can adjust the temperature from across the room.
