5 Ways to Keep Pests Out of Your Home’s HVAC System

Nobody wants to deal with a pest problem. They cost time, money, and mental energy. They’re revolting. They’re nerve-racking. They’re also more preventable than you might think. All you need are a few expert tips and a little preventative effort.

Pests enter your home for one of three reasons: they are looking for shelter, food, or water. Cutting off their access to these items is the quickest way to keep them away from your home.

There are a few areas of your home that provide these services more readily than others. Bathrooms, basements, attics, and your home’s heating, ventilation, and cooling systems, to name a few. 

In addition, your HVAC system provides hiding places and plenty of moisture, making it a prime target for potential infestations and one of the first places you should address if you’re taking preventative measures.

In today’s post, we’ll focus on those preventative measures and walk you through how to protect your home’s HVAC system from pest infestation.

Conduct a Thorough Walkthrough of Your Property.

This step isn’t specific to your HVAC, but it’s an important part of any pest-prevention strategy. It will provide you with a good baseline understanding of your home and whether or not there are any problem areas. After all, if pests can easily get in, they’re much more likely to hide and multiply throughout your HVAC system. Here are some things to look for:

Examine Your Walls for Any Gaps or Cracks.

Examine your doors and windows, paying special attention to the frames. Check the seals to see if they are loose or crumbling.

Examine any windows screens you have. Are any of them torn or have holes in them?

Check the plumbing in your home. Look for hidden leaks beneath sinks.

Examine the connection points where water enters your home to ensure that the seals are tight.

If you notice any problems similar to those listed while performing this walkthrough, fix them as soon as possible. Even if the problems are minor when you first see them, they can grow significantly larger if they are not addressed quickly. Now that you’ve completed your basic home preventative measures, it’s time to move on to the HVAC system itself.

Cleaning Your Ducts is a Must.

It’s been far too long if you can’t recall the last time you cleaned your ducts. Your air ducts serve as a thoroughfare to every room in your house. Pests can get into them and then get anywhere. 

Anyone concerned about pests should have their ducts cleaned and inspected regularly. You can clean your ducts independently, but it will never be as effective as a professional cleaning because the average person lacks the high-powered vacuums and rotary brush cleaners that professional teams have. 

Our recommendation is to contact a team that can inspect and clean your ducts professionally. They will be able not only to remove any existing mold, dust, or debris but will also be able to repair any loose seals that could allow future pests to enter.

Don’t Forget to Keep Your Outdoor Units in Good Working Order.

The HVAC system in your home does not exist solely within your home. For example, your air conditioning condenser is a common target for pests, tiny rodents like mice, and rats. This is because it is installed outside, processes moisture, and is frequently left alone after installation. Here’s what you can do to safeguard it:

Keep the area around your condenser free of debris. 

Pests can hide in any accumulated debris, firewood, or similar outdoor ephemera. Pests will assemble in this disarray until they can make their way to your unit and then to your home. They are less likely to breach if there is nowhere nearby for them to hide.

Bath your condenser every few months. 

All you need to do is scrub the unit’s exterior with mild dish soap (such as Dawn) and a rag. It’s just one more step toward keeping pests at bay. Pests thrive in filth, so keep your environment clean. If you have a DIY home checklist, mark this as a task to complete every three months.

Install Exterior Flue and Vent covers.

Exterior vents are another popular entry point. You can find these attached to your attic, dryer, or soffit. Make sure you invest in pest-proof covers, particularly flues. Small rodents can use their sneaky little paws to pull covers off if they are not secured.

As shown in this post, there are numerous small steps you can take to protect your home’s HVAC systems from pest infestations. One of the most important is to keep your ductwork clean and clear. While there are some things you can do on your own to keep your ducts clean, it’s best to seek assistance from professionals like the team at Blue Sky Heating and Air LLC.
