Having an air conditioner window unit facing outside of your house is the standard and correct orientation for installation. When installed properly, with the front (air intake) side facing inside the room and the back (air exhaust) side facing outside, it offers several benefits:
Efficient Cooling: The air conditioner is designed to draw in warm air from inside the room, pass it over the cooling coils, and expel the cooled air back into the room. By facing the air intake towards the indoor space, it can efficiently cool the room by removing the warm air.
Heat Dispersal: The back of the air conditioner, where the compressor and condenser are located, releases heat during the cooling process. By facing this part outside the room, the heat generated can be effectively dispersed outdoors, preventing it from recirculating and heating up the room.
Proper Air Circulation: Correctly positioning the air conditioner ensures that it can draw air from the room and expel it outside, maintaining proper air circulation. This helps to avoid hotspots and ensures even cooling throughout the space.
Condensation Drainage: Window air conditioners produce condensation as part of the cooling process. When facing the outside, any condensation that forms on the coils will drain away outside the house, preventing the need for a drip pan inside the room.
Safety and Aesthetics: Facing the air conditioner towards the outside reduces the risk of objects falling into the unit, potentially causing damage. Additionally, from an aesthetic standpoint, the outdoor-facing part of the unit is generally designed to blend in with the exterior of the building.
Noise Reduction: While air conditioners can produce some noise during operation, having the unit facing outside can help to minimize indoor noise levels, making for a more peaceful and comfortable living environment.
Overall, installing an air conditioner window unit with the correct orientation provides efficient cooling, proper air circulation, heat dissipation, and improved safety and aesthetics. Be sure to follow the manufacturer's installation instructions and use any sealing materials provided to create an airtight fit in the window, which can also enhance energy efficiency and performance.
