How Pests Use Duct Systems To Invade Your Home

Technically, a well maintained, regularly checked AC has safeguard features that effectively blocks the little intruders from entering the unit, but some pests are so tiny they only need a little opening to successfully infiltrate their way inside.

Roaches, bugs, beetles, termites, ants, and even rodents can invade any house through the small openings in your outdoor home air conditioning service unit. The saliva and droppings of these critters can cause serious irritation to people with a respiratory condition such as asthma or allergies. It can also affect the quality of the indoor air which could lead to serious health conditions.

How To Pest-Proof Your Home – Duct Systems

Blocking off critters from using your AC as an entry point to invade the house while keeping it free from irritants and other health risks with this list:

Inspect duct seals. Over time, some of the AC duct work may degrade and fail to function. This is especially true for duct tape, which may start to peel off as it is continuously exposed to constant temperature changes. Invaders can use these tiny openings to enter your home. Additionally, air leakage is more likely to happen when gaps are exposed by a peeling duct tape.

Moisture prevention. A puddle of water seems like a fun spot for young children to play in, but the same puddle in or around your home – more importantly, one that is near your outdoor AC equipment – can mean more insects may find their way into your house. All living creatures rely on water to survive, that includes insects.

Preventive pest control. If unwanted invaders are a common problem in your area, conducting a regular preventive pest control counter-measure will help prevent infestation. Talk to a pest control contractor for regular pest-control measures.

Routine maintenance. Keeping your outdoor air conditioning condenser and the overall home air conditioner service system clean is essential for its longevity. It is also a way to keep critters from ever wanting to ever step on your property. Find the best HVAC contractor near you to learn more about preventive maintenance.
