As the weather warms and animals come out of winter hiding, your HVAC system can become an unexpected magnet for rodents and pests—especially in the spring. HVAC systems offer warmth, shelter, and tight spaces ideal for nesting. Unfortunately, this seasonal attraction can lead to serious problems if left unaddressed.

1. Chewed Wires and Electrical Hazards

Rodents like mice and squirrels are notorious for chewing on wires. Inside your HVAC system, this behavior can lead to damaged control boards, short circuits, or even fire hazards. It’s a common cause behind the dreaded search for “AC not working” in early spring.

2. Duct Damage and Airflow Issues

When rodents find their way into ductwork, they can cause punctures or disconnections, leading to air leaks and decreased system efficiency. Not only does this compromise your indoor comfort, but it can also send your energy bills soaring.

3. Unpleasant Odors and Health Concerns

Rodent infestations can leave behind droppings, urine, and even deceased animals in or near your system. This creates foul odors and can circulate allergens or bacteria through your home’s air.

4. How to Pest-Proof Your HVAC System

• Seal gaps around outdoor units and entry points to keep rodents from getting inside.

• Install wire mesh screens over vents and intakes.

• Keep the area around your condenser clear of clutter, debris, and vegetation where animals might nest.

• Schedule regular HVAC inspections, especially in spring and fall.
