The possibility of dead animals getting trapped in the air ducts isn’t something most homeowners normally think about or prepare for. It is, however, a much more common issue than you might think. This occurrence causes discomfort due to the foul odor the carcass emits. Attics, basements and wall crevices are enticing places for small animals to seek refuge, and air ducts help them maneuver their way through your home. This issue, if not addressed immediately, could wreak havoc on your ventilation system and require you to call a home furnace repair specialist.
