Effective HVAC systems work when there’s a proper exchange of indoor and outdoor air, but this can give outdoor pests and opportunity to get into our homes. When an HVAC system is maintained the right way, it has safeguards to keep pests outside. But most unwanted pests only need a tiny space to get inside. When pests leave saliva, skin cells and droppings behind, serious issues can arise for sufferers of asthma and other respiratory conditions from poor indoor air quality. It’s good to know that good pest prevention is also beneficial to our HVAC system. We need to find out which pests we’re potentially dealing with and how to prevent them from getting in. Rats do well in colder climates and roaches prefer warmer regions, but these two pests both share the need for water, food and shelter. This need is what has them searching for areas in our homes. Rodents are known to use sensitive components to your system as chew toys. Chewing and nesting can cause damage. They can also die in the ductwork if they can’t find their way out, leading to foul odors. Pests that dig or make holes can cause leaks that can be costly to repair because they will force your HVAC system to work harder to get the level of comfort desired.

How Can I Maintain My HVAC System & Pest-Proof My Air Ducts & Vents

1. Seal off entry points. You can have a pest control company come in to do an inspection of your home to find access points. If the pests are using your HVAC system to get in, the technician can place protective screens over the vents. They are also able to find areas that are drafty and are most likely the result of openings large enough to let pests in.
2. Seal ductwork. The materials that make up ductwork in an HVAC system will eventually degrade and fail. Duct tape won’t last forever and the gaps that are created are an opening for pests and will also waste energy, resulting in higher utility bills.
3. Moisture control. When puddles of water form in or around our home or close to the air conditioner condenser it creates an environment that attracts pests. You can use dehumidifiers in areas where dampness is more likely to occur to prevent any issues. There aren’t many pests that don’t need a source of water to survive.
4. HVAC maintenance. Have regular maintenance performed on your HVAC system. Inspections and tune-ups done on a regular basis is the best way to keep it in check and to discover any signs of infestation.
5. Pest control. Having professionals come to your home for pest inspections and prevention will do a lot in controlling possible infestations.
