What's Crawling Around in Your Home's Air Ducts?

It’s unpleasant to consider, but often times dust isn’t the only thing that is in your duct system. You might hear animal noises coming from air ducts and realize you have freeloading tenants. You can attempt to lure the critters out but if they’re nesting they may not leave their babies. Call Service Experts Heating & Air Conditioning for a complete duct cleaning and we will assure your duct system is free of all these unwelcome house guests, including:


Not much is worse than aiming to kill a spider and watching is escape into your air vent. You can’t get to it now and all you can do is sit on the couch and imagine the spider laying all those baby spiders. You may even think you hear a couple scampering around your duct system. Don’t worry. Service Experts Heating & Air Conditioning will come to your home and give you a full duct cleaning and make sure that spider and any of her creepy-crawly friends are out of there. Babies, too.


When rodents make their way into your duct system, normally through openings in the duct work and cracks in the foundation or home exterior, it causes many issues. First, wildlife can leave droppings behind and can ruin anything they come across, including Christmas decorations or baby toys you’re storing in your attic. Second, animals tend to chew, which can cause exposed wiring. That mixed with the dried grass and leaves they’re likely bringing in to manufacture a nest, and now you have quite the fire danger in your duct system, your attic, or behind your walls. A thorough duct cleaning can get rid of rodent droppings or nests, but you might also need to call an expert wildlife removal company to remove the rodents and possibly an electrician if there was any wire damage.


Birds usually find safe and dry places to nestand your air vents are perfect. Nests mean baby birds, which means they are finding food for babies, and that means BUGS. If you discover birds in your vents, you’ll probably end up with creepy-crawlies in your home. But that’s not the worst part. Birds build nests in your vents, and given the great amount of materials they use to create said nest, it can result in completely clogging a vent, stopping any airflow. As with mice, squirrels, etc., a professional duct cleaning from Service Experts Heating & Air Conditioning can get rid of any droppings, feathers, or other likely illness-carrying leave-behinds. You might also need an expert animal removal company to actually remove the birds from air vents or attics.

Mice in Air Ducts

If there are mice in the ductwork, you should take steps to quickly remove them. Mice gnaw wires and leave refuse like all rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the highway of your home, they usually die in there. This creates a health hazard, and you may notice unpleasant scents.

You may guess mice from the sounds you hear – plenty of scratching and scrabbling inside walls. Or you might actually notice one making an escape into the heating vents in your walls. You might even confirm their status by inspecting the ducts for mice leavings. If you suspect mice you have a couple choices. You could trap them yourself, by setting traps inside each vent and checking them in the morning. Or you might decide to pay for a specialist.

Once you have verified that the mice are gone, you should have your air ducts thoroughly cleaned by an HVAC company. If mice have been living in the walls, they will have left mice refuse in your ducts. Mice leavings are toxic, and if you ignore them in your ducts they can make you and your family sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will clean out most debris from your home’s ventilation system.
