Room air conditioner installation and operation tips
Following these tips will make installation and operation of your room air conditioner quick and easy.
Be sure the power outlet is within reach of the plug and is the correct amperage size.
Make sure the air conditioner is level side to side and tilted back slightly to prevent water leaks into the house.
Don’t put furniture or other objects that that could block air circulation near the air conditioner.
Set the thermostat as warm as is comfortable for you. Warmer settings achieve greater energy savings.
On humid days, set the fan speed on low; the slower air movement removes more moisture from the air.
Use an extra floor, table or ceiling fan to spread the cooled air around.
