Spring and Fall: Clean any dirt or debris with a low pressure hose.

Summer: Shrubbery, plants and other landscape materials should be trimmed to provide a clearing of 2-feet around the unit, according to energy.gov. This is because landscaping can block airflow around the unit. Be sure to monitor the unit periodically for debris from dryer vents, lawn mower clippings, and leaves.
