Well, here’s another one you might not have put much thought into:

Keep the Area Clean

Bugs and smaller rodents have an uncanny knack for making their way into HVAC systems. One of the results is lower air quality. Make sure your having regular maintenance done on your HVAC system—this will help keep the system clean and help catch any new infestations. A few things you can do is to get rid of standing water around your outside unit, clean up any debris that gets into the vanes, and change out filters regularly. Our friends at Turner Pest Control in Jacksonville have a bit of a unique problem—in Florida they have ants called “Tawny crazy ants” that are known to invade electrical components—especially HVAC units, where they can cause units to short out. As you can see, bugs and insects can cause some major headaches in HVAC systems.

Seal Ducts

Probably the easiest entry point for insects is through your ductwork. Loose seals and cracks give bugs the opportunity they need to enter and infest your HVAC system. Sealing your ducts is relatively easy and affordable. You’ll need to purchase foil tape for smaller cracks, and sealant for large holes. While there are guides for maintaining your ductwork, if you don’t feel comfortable taking this on, or your ductwork isn’t easily accessible don’t hesitate to contact an HVAC professional to have ducts cleaned and sealed.

Schedule Regular Pest Control Treatments

The best solution to keep pest and creepy crawlies out of your heating and air system (along with the rest of your home!) is to schedule regular pest control treatment and maintenance. Homeowners should opt for quarterly treatments to deal with different seasonal bugs, and monthly treatments if you have a history of serious infestations. Need a Pest Control Estimate?
