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

It’s unpleasant to consider, but occasionally dust isn’t exclusively what is in your duct system. You might hear animal noises coming from air ducts and fear you have unwanted guests. You can try and lure the little guys out but they may be nesting and refuse to leave their babies. Call Service Experts Heating & Air Conditioning for a thorough duct cleaning and we will make sure your duct system is free of all these unwelcome house guests, including:

Insects and Bugs

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 lie in bed and imagine the spider laying all those spider eggs. You may even swear you hear a few racing 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 assure that spider and any of her bug friends are evicted. Babies, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, usually through gaps in the duct work and cracks in the foundation or home exterior, it causes multiple issues. First, squirrels, mice, or raccoons can leave droppings behind and can destroy anything they encounter, including Christmas decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can result in exposed wiring. That joined with the dried leaves and twigs they’re likely taking in to build a nest, and now there’s quite the fire risk in your attic, duct system, and behind your walls. A good duct cleaning can eliminate rodent droppings or nests, but you might also need to call animal control to remove the rodents and possibly an electrician if there was any wire damage.


Birds typically get into safe and dry places to nestand your air vents are perfect. Nests mean baby birds, which means they are bringing food to babies, and that means BUGS. If you find birds in your vents, you’ll probably end up with six-legged and eight-legged critters in your home. But that’s not all. Birds construct nests in your vents, and given the vast amount of stuff they use to assemble said nest, it can wind up totally clogging a vent, preventing 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 may also need a professional wildlife removal company to actually remove the birds from air vents or attics.

Mice in Air Ducts

If there are mice in your home’s ductwork, you should take steps quickly to remove them. Mice gnaw electrical wires and leave refuse like all rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the road system of your home, they eventually die in the ducts. This creates a health hazard, and you may notice it due to the smell.

You may suspect mice because of the sounds you hear – plenty of scratching and scrabbling inside walls. Or you may actually spot one making an escape into the heating vents in your house. You might even confirm their passage by inspecting the ducts for mice leavings. If you think there’s mice you have a couple choices. You can trap them yourself, by placing traps inside each duct and checking them every morning. Or you can hire a pest control company.

Once you’ve determined that the mice are gone, you really should have your ducts expertly cleaned by an HVAC company. If mice have been living in the walls, they will have left droppings in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will eliminate most debris from your home’s air ducts.
