Most maintenance should be performed only by a qualified service technician. But here are some things that you can do to assure optimal performance:
• Keep ground mounted outdoor units clear of debris, clutter and weeds; they can reduce the airflow to the unit.
• Use caution with weed trimmers around the unit to prevent damaging control wiring.
• Keep pets away from the unit; pet urine can cause expensive damage.
