You shouldn’t smell any noxious odors wafting from your HVAC registers when you have clean ductwork. If you start getting a distinct odor of decay whenever the blower fan cycles on, the most likely cause is a dead rodent somewhere in the duct system. The odor from even a small carcass can be quite unpleasant, and the decomposition can adversely affect your indoor air quality. There are a couple of ways to address a dead rodent problem to get rid of the bad smell and keep contaminants out of your air supply:
If You can Tolerate the Task, do the Cleanup Yourself
First, you’ll need to locate the body, so open a few windows for a while to thoroughly air out the house, then close them and turn on your HVAC fan. With the fan running, do a smell test at each of your registers. The body is likely in the ductwork near the register where the smell is the worst.
Next, remove the register cover and use a flashlight to look around inside the duct and find the body. Depending on how far in the carcass is situated, you may need to employ your vacuum hose or a wire coat hanger to pull it near enough to reach.
Lastly, wearing disposable or rubber gloves, scoop the body into a plastic bag, then tie it up securely. After you dispose of the carcass, spray the duct thoroughly with disinfectant and put the register cover back in place.
Call Your HVAC Pro for Help
If you don’t have success locating the dead body, or you just don’t want to deal with a foul-smelling mess, one of your HVAC contractor‘s technicians may be able to handle the cleanup. If not, your contractor may suggest calling in a pest removal company. Either way, it’s wise to schedule an appointment for a duct inspection so the spot where the animal entered can be found and sealed.
