Avoiding Pest Infiltration in the HVAC System

Whether it’s the cold winter or the hot summer, your home’s HVAC system helps keep you comfortable in large part by exchanging outdoor and indoor air. It’s more complex than this in reality, of course, but this is the broad process for basic heating and cooling services.

At My Buddy the Plumber in St. George, we’re here to help you stay diligent about other materials that might make their way into your outdoor/indoor air exchange system – namely pests, which are a risk both during summer and winter. Let’s go over the connection between your HVAC system and pest control, plus some specific tips for ensuring pests don’t invade through the same areas that keep you warm during the winter.

How HVAC and Pest Control Relate

When pests enter the home, they can have a direct impact on air quality and HVAC efficiency. This is in part due to their ability to aggravate respiratory symptoms like allergies and asthma due to the droppings and skin particles they leave, but also due to the way they can chew up, clog or otherwise damage important components of the HVAC system.

But in addition, pests may often actually be entering the home through the same system they’ll help damage later on. Especially during winter, they’ll be on the hunt for any form of warmth and shelter they can find – your warm heating vents will certainly seem inviting, as might several other areas in your home. Without the right precautions, you could find you and your family aren’t the only ones taking advantage of the heat.

HVAC Pest-Proofing Tips

Some basic tips for avoiding pest infestation through your home’s HVAC system:

  • Sealing: For starters, sealing all potential points of entry is the single most meaningful thing you can do. If you need assistance, our technicians are happy to assess your entire system, looking for areas where pests might be able to gain access and filling them with protective screens or other materials. We can also help you locate drafts in the home, which generally signal openings large enough for insects to invade.

    In addition, take some time to seal your ductwork throughout the home. Ductwork will wear down with time, especially if you’ve already used duct tape on it in the past. Any gaps here create paths for pests to move and reproduce.

  • Humidity and moisture: Particularly near condensers and AC components, but really for anywhere in the home, avoid pudding water and high humidity. Pests require water to stay alive, and will gravitate to these areas.
  • Routine pest control and maintenance: On top of the above, both we and various pest control companies offer great inspection and tune-up services that will be very helpful here. In our case, these services also include several areas outside the world of pests.
