Are you concerned that pests might get inside your HVAC system? It’s certainly a valid worry, although pest invasions of HVAC systems are really not that common. The HVAC just doesn’t present a habitat that’s all that inviting. Nevertheless, it pays to be aware of the symptoms of pest invasions and to know what to do about it if it occurs. Let’s look at what kind of pests and HVAC parts might be a problem when they meet.
Ductwork
Ductwork is usually out of sight, tucked away in the attic or basement. Segments can become detached or develop holes and cracks. Breaches allow conditioned air to escape and unconditioned air to get in. These breaches might also allow pests such as squirrels, rodents, and various types of insects to get inside. Although it would be hard for these creatures to survive in a habitat that is continuously being blasted by high-velocity rushes of air, they might get inside during periods when you aren’t using the equipment and eventually make their way inside the house. One way to tell if you might have this unwanted combination of pests and HVAC is if you start smelling unpleasant odors from your HVAC system. The best solution is to call a company that does duct cleaning, and also to call a pest-control company to inspect your home.
If you’re able, repair ducts with mastic sealant or aluminum foil tape.
Vents and Flues
Various types of insects may invade vents and flues, including spiders, cockroaches, ants, and wasps. While you can get up on the roof and spray any insect nests, you might be better off hiring a pest-control specialist to assess the situation and treat your home as needed. Clean and vacuum vent grilles regularly.
Condenser
Some pests will try to winter in your outdoor condenser. Do not cover it during the winter. Spray wasps with a high pressure blast from the water hose, but don’t damage your AC parts. Rodent or ant invasions may require a pest-control expert to address this especially bad combination of pests and HVAC.
