Kolter Homeowner Guide

Maintaining proper drainage Check the drain line for proper function at the beginning of each summer. It’s recommended to have a professional service the line. Ensure the secondary drain line drains properly. The unit’s instruction manual includes directions for doing so.

Finally, some heating/cooling units are in utility closets. In that case, the primary drain line will run through an interior wall but end outside. Some units have a warning device that cuts power to the unit if the drain pan fills with water.

Maintain space around outdoor condenser units and lines by trimming back landscaping.

Check the outdoor condenser unit on a regular basis for debris. Before doing so, turn off the air conditioner. Then check for anything — grass and leaves, for example — that could impede air flowing from the unit. Remove any debris with a water hose (an adjustable spray nozzle makes it easier). Check under the unit and remove any debris that’s accumulated in the base pan.

CAUTION: Use only enough water pressure as is necessary to clean the condenser unit. Too much pressure could damage the unit’s coils.

Care and maintenance The following are tips for maintaining the condensation drain line.

HOME TIP: Secondary drain lines typically are over doors or windows. Water dripping in these locations may indicate a clog in the primary line.

SERVICE TIP: If debris has accumulated in the condenser unit, call for service to avoid damaging it.
