Your HVAC system can harbor some nasty pests, which can trigger allergies and reduce your home’s indoor air quality. For Spring Hill, Florida, residents wanting to stay ahead of the game, here are some common critters to be mindful of.


Rodents love tight spaces, which is why it’s not unusual to find mice and rats living in HVAC systems. Unfortunately, rodents can also cause significant damage if left to their own devices. They can chew through HVAC components and refrigerant lines, build nests in the ductwork, and cause other costly repairs. If you do notice rodents crawling around in the ductwork, invest in professional extermination as soon as possible.


Spiders, cockroaches, and dust mites thrive inside undisturbed nooks and crannies in the home. As such, they’re eager to take up space in your HVAC system. While certain insects like non-venomous spiders may not pose a threat, others like dust mites can trigger asthma and allergy symptoms. Some insects, including cockroaches, even carry disease. Having your ductwork cleaned and properly maintained can help keep all these baddies in check.


It’s a scary prospect, but snakes commonly seek shelter inside ductwork because they can’t regulate their own body temperatures. Because of this, it’s possible to have a snake nest inside the HVAC system. Snakes can also coil around condensers and damage fan blades, making them a nuisance to all Florida homeowners.

Small Mammals

Critters like squirrels and raccoons don’t often find themselves inside a home’s ductwork, but it’s not completely unheard of. In fact, these small mammals are highly likely to get into your home’s attic space, so it’s only a matter of time before they work their way into the ducts. It’s important to call a pest control company to handle the situation, but you’ll also need a ductwork cleaning from us to remove any waste left behind.
