Wildlife Invasion Alert: How Deer, Raccoons, and Birds Are Costing Woodside Homeowners Thousands in AC Damage This Year

Woodside residents are facing an unprecedented challenge in 2025 as local wildlife increasingly targets residential HVAC systems, causing costly damage that can leave families without cooling when they need it most. Woodside is home to an abundance of wildlife. From coyotes, to owls, to mountain lions, our lush landscape makes a welcoming home to many species. Unfortunately, this natural beauty comes with hidden costs for homeowners who find their air conditioning systems under siege from unexpected intruders.

The Growing Threat to Woodside’s Cooling Systems

The problem has escalated dramatically in recent years as urban development continues to expand into natural areas, wildlife increasingly interacts with human structures, including HVAC systems. Many animals are attracted to HVAC systems because they offer: … These systems become a literal haven, especially outdoor condenser units, attic ductwork, and crawlspaces, which can be easy to access for nimble or burrowing creatures.

The most common culprits causing havoc in Woodside include:

• Raccoons: These larger mammals are strong and can cause physical damage to the unit by trying to access the interior. They can dislodge parts and create openings that allow other pests to enter. These intelligent animals are strong enough to tear open vent covers or insulation. Once inside, raccoons can crush ducts and leave behind urine and feces, which not only damages the system but also creates a serious biohazard risk.
• Birds: Birds often find the nooks and crannies of HVAC units perfect for nesting. While it might seem harmless, nests can block airflow and cause the system to overheat. Birds, on the other hand, can clog drainage systems with their nesting materials, while insects may infiltrate the unit, disrupting its inner components.
• Deer and Other Large Wildlife: While less common, larger animals can cause significant damage to outdoor units when they come into contact with condensers or attempt to access shelter near HVAC equipment.
• Rodents: Mice and rats are notorious for seeking shelter in warm, enclosed spaces, making your HVAC unit an ideal home. These critters can chew through wires, causing electrical malfunctions and potentially leading to costly repairs. Rodents are nocturnal creatures known for eating and contaminating food, chewing on electrical wires, nesting on insulation, making holes on air-ducts, among other damages that can result in major property damage.

The Hidden Costs of Wildlife Damage

Wildlife damage to HVAC systems can be subtle at first, but it can escalate quickly. Here’s a look at the potential financial toll: … Energy loss due to leaks- Up to 30% increase in energy bills (U.S. Department of Energy data).

The damage extends beyond immediate repair costs. The nesting materials from birds, squirrels, opossums, and raccoons can block airflow. This can dramatically reduce the efficiency of the HVAC system and force it to work harder than it should to cool or heat your home. The added strain can shorten your HVAC unit’s lifespan, potentially causing components like motors, fans, and compressors to break down.

Even more concerning are the health risks. When animals nest inside ducts or near air intakes, they can introduce dander, fur, droppings, and parasites into the system. This contamination can circulate allergens and pathogens throughout your home, aggravating respiratory conditions and compromising overall air quality.

Peak Season for Wildlife Intrusions

Intrusions typically spike in late fall and early spring. During fall and winter, animals seek warmth and shelter, often finding it in HVAC systems. In spring, animals like squirrels and raccoons look for nesting sites to raise their young, making attics and ductwork prime targets. This timing couldn’t be worse for Woodside residents, as it often coincides with the transition into cooling season when AC systems are most needed.
