Did you know that your HVAC system could be an open door for pests to come uninvited to your home? When people have an infestation problem, the last place they think could be a cause of it is their HVAC system. Let’s think about this for a second. In order for an HVAC system to function properly, there has to be an exchange of indoor and outdoor air. This can provide an opening for the pests from outdoors. While a well-maintained system has several safeguards to prevent them from getting inside, many unwanted critters only need a very tiny amount of space to sneak in. Many people don’t think that maintaining a properly functioning HVAC system and controlling pests in your home go hand in hand. Because pest problems vary by region and climate, it’s helpful to know which pests are most common in your area. Furthermore, the saliva, skin cells and droppings left behind by pests can be serious irritants for sufferers of asthma and other respiratory conditions, creating an indoor air quality issue. Do you notice a sudden undetectable odor? It could be due to the droppings, dead pests, and other pest debris left behind in your HVAC system that can cause your interiors to smell. As conditioned air circulates through the duct system, the odors emitted by pests will move into your home.
It’s also important to understand what attracts them to your indoor spaces, how to block their entry and how to eliminate them once they’ve invaded your home. Fortunately, what’s good for pest prevention is usually also good for your HVAC system. What are the best ways to prevent pests from entering your home via your HVAC system, you ask? Check out the following ways to maintain a no-pest zone:
The first and most important step is to seal off any points of entry for pests. Consult with a pest control professional that can provide you with a detailed inspection to discover any areas that have holes where critters can enter your HVAC system and home. If they do find areas where pests are gaining access to your home via your HVAC system, call a technician immediately to fit vents with protective screens.
Seal your ductwork. In older systems, duct material can degrade, resulting in gaps and holes that are perfect gateways for pests to enter your home. Sealing your ducts can also help preserve valuable energy.
Check for any bodies of water in and around your home, especially near your outdoor air conditioning condenser. Pests need water to survive and areas with excess moisture are areas for critters to thrive.
When pests enter your HVAC system and its components, they can lead to a range of problems including damage to your home. When pests and the source of the problem are not discovered quickly, the infestation can turn into a huge problem rather quickly. Don’t let this problem get out of control. Be proactive in preventing the problem rather than reacting to it.
