Air Conditioner - Heat and Cool Unit Not Heating Properly

Some Air Conditioners have the feature of providing both cool and warm air. With a Heat and Cool model, there are actions you can take to achieve maximum heating performance from the appliance.

Optimizing Heating Effectiveness From a Heat and Cool Air Conditioner

• Make sure the mode switch or selector switch is set to High Heat and the temperature control is set to a higher number.
• Make sure the air filter has been cleaned in the last 30 days. For more information, please see our Air Conditioner - Cleaning the Filter article.
• Make sure nothing is blocking the flow of air coming from the Air Conditioner such as furniture, drapes or lamps.
• Make sure the air flow from the outside rear grille is not restricted. This may cause the appliance to cycle off due to compressor overload.
• Use the Electric Heat option on models that offer this feature. This turns off the heat pump (on models so equipped) and will warm the room with electric heat only.
• Adjust the air directional louvers upward to promote improved airflow.
• Check all windows and doors. Make sure the windows and doors are closed and have a good seal to prevent drafts and heat loss from the area being heated.
