Bugs crawling through your air vents and into your home seems like something out of a horror movie, but unfortunately, you aren't the only one who wants to cool down on a hot summer day. Bugs are always on the hunt for a way to sneak into your home, and the HVAC system gives them a perfect entry point. Pests don't just infiltrate your home but can cause malfunctions and decrease indoor air quality.

Install Screens Over Air Vents
If you have been noticing more small insects and spiders crawling around your home, they may have snuck their way in through your home's air vents. To stop these pesky invaders, you can install insect screens on your indoor and outdoor air vents. It is possible to do-it-yourself removing the vent cover and using it as a pattern to cut the insect screens, which can be attached to the vent using caulk.
Search For Cracks & Plants
While you have the caulk for installing the air vents, you can also use it to seal any cracks present in your walls, foundations, and windows that bugs can use as an entryway. We recommend clearing away any foliage within a foot of the outdoor AC unit. It is easier for bugs to get into your home via a window air conditioner as they can sneak between the window and the air conditioner. If you notice bugs getting in this way, we recommend having a professional HVAC technician make sure that the unit was installed correctly, and you can install insect screens.
Keep Things Clean
Bugs have a way of finding their way inside your home, even with screens installed. If they keep finding their way into your AC system, they can lower your home's air quality. Conducting regular maintenance on your HVAC system keeps your system clean while keeping an eye out for possible infestations. Bugs can also get in or get stuck to AC filters, so we recommend cleaning or changing them at least every 1–2 months.
