Window AC / September 11, 2018 / Jacqueline Bizier.
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.
When purchasing a window air conditioner it is very important to purchase one with the proper cooling capacity. An air conditioner that is not properly sized will not work as efficiently as one that is sized properly. This is one of the most common mistakes made when selecting air conditioners. Use an air conditioner size calculator to select the proper sized unit for the room you want to cool. Undersized air conditioners will run continuously and not cool the space adequately and an oversized unit will cycle on and off too often. This increases equipment wear and can actually cause fuses to fail.
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.
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.
