Besides changing my filters, what maintenance should I do on my HVAC?

Most maintenance should be performed only by a qualified service technician, however, there are a few things you can do to ensure optimal performance.  Keep ground mounted outdoor units clear of debris, clutter and weeds; this can reduce the airflow of the unit.  Use caution with weed trimmers around the unit to prevent damaging control wiring.  And lastly, keep pets away from the unit; pet urine can cause expensive damage.
