4 Ways To Keep Pests Out of Your HVAC System

If you want a more comfortable home, you need to know the ways to keep pests out of your HVAC system. Any season is prime time for pests to make their way into your home’s system.

And, at the same time, you need to know how to keep them out.

Read on to learn …


4 Simple Ways to Keep Pests Out of Your HVAC System.


1. Clear Your System’s Surroundings


Pests like rodents or raccoons may seek out your HVAC unit for two main reasons.

  • Shelter: especially if it’s near weeds and bushes, it may provide cover during hot summer days or frigid winter nights
  • Food: if the area is near your trash can, they could be attracted to the unit for a meal

Make sure to clear the area around your HVAC unit. In addition, schedule regular maintenance and cleaning.  A clean HVAC system with no broken parts will deter pests from entering.


2. Banish Dirt and Dust


Investing in duct sealing can prevent pests from entering and damaging your HVAC unit. When ducts are cracked or loose, pests can make their way through and settle in. If your system has leaky ducts, it’s time to seal them. Not only are you preventing pests from entering, but you’re blocking potential for bad indoor air quality, caused by excrement or allergens pests produce.


3. Check and Cover Your Vents


Pests can make their way into your home through exterior vents. Dryer vents and exhaust fans are attractive because the air coming from them is warm. If you already have a vent cover installed, you can stop pests like birds from coming in and making nests in your vents. Vent covers must also be secure so pests cannot chew or scratch through them. If you suspect that your vent cover may be damaged, call a professional to replace or repair it.


4. Plan for Pest Control

We can’t always deter pests from coming around our homes, but if you have regular trouble with pests, you may have an infestation. Keeping up with annual pest control can keep pests from being attracted to your home. And, you’ll lower the risk that they’ll get into your HVAC system.
