Caulk or sealants can be effective for small holes around the unit, while wire mesh can be an excellent barrier for exposed vents. Ensuring no easy access to your system can drastically reduce pest problems.

Keep the Area Around Your Outdoor Unit Clean

Pests often nest in overgrown shrubs, stray leaves, or piles of debris near your outdoor AC unit.

A well-maintained space lowers the chances of pests near your system and can improve its airflow and performance.

Utilize Pest-Repelling Solutions

Some Olympia homeowners rely on pest control products designed to deter invasions near their AC systems. For example, specialized sprays around the base of your outdoor unit can keep ants at bay, while ultrasonic devices may discourage rodents from coming near. Another simple yet effective option is to place fragrant herbs like mint or lavender near the unit, as these naturally repel many insects.

Regularly Check for Signs of Pest Activity

Catching pest activity early can prevent minor issues from escalating into major damage. Signs to look for include chewed wires, droppings, insect nests, or unusual smells emanating from your system. Additionally, if you notice inconsistent performance, this could also signal pest-related problems.

Invest in Routine AC Maintenance

Install Protective Barriers

Exterior barriers like cages made of durable materials can shield your outdoor unit. These enclosures are particularly beneficial if your home is in a wooded area or prone to rodent issues. Protective screens over any exposed vents or air intakes also ensure that pests such as birds or small mammals cannot slip inside.
