Window AC / September 12, 2018 / Lundy Brochu
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.
The ductwork for the distribution of the air is also all ready in place. The ductwork may need some modification to make it work well for air conditioning but the major part of it should be adequate. To use the existing furnace and ductwork a coil will need to be installed at the furnace. An outdoor condenser unit will be installed outside and copper tubing will be used to connect the coil to the outdoor unit. Some electrical wiring will need to be done to power the outdoor unit. Low voltage wiring will be needed to hook the thermostat the furnace and the outdoor unit together so that they can talk to each other. Basically the thermostat will just tell the furnace to run the blower on high speed and the outdoor condenser to start up.
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.
