Window AC Installation

Some general tips and instructions for installing window air conditioners follow. However, please install your uinut in accordance with the directions provided by the manufacturer.

  1. Check your home wiring for the right circuit amperage and voltage. Avoid using electrical lines that are already loaded with appliances. Also, do not connect a 208 Volt unit to a 115 Volt line or a 115 Volt unit to higher lines. If a fuse blows, shut off the unit and check the load and wiring.
  2. Be sure that the outlet is properly grounded. Never remove the grounding prong from the plug as it will create an electrical hazard.
  3. If at all possible, install the unit in a shaded window.
  4. Check to make sure that the unit is installed level from side to side. Generally, you do not want a window air conditioner to be 100% level from back to front, however. The outside side of a window air conditioner usually needs to be tilted down a bit to allow for proper condensate drainage.
  5. Take steps to seal the area where the window closes on top of the air conditioner. Weatherstripping can be used as a vibration damper when a storm window or screen rests on the top of the appliance.
  6. If your air conditioner is installed in a vinyl replacement window, you can use a wood reinforcement strip below the appliance to distribute its weight. An air conditioner is heavy enough to distort many vinyl replacement windows. Also, consider screwing L-brackets into the window channel instead of letting the unit rest against the window sash.
  7. If you are in doubt or inexperienced with making electrical connections or have questions about your installation that cannot be answered by the manufacturer of your air conditioner, seek the services of a qualified electrician or air conditioner installer.
