One of the most necessary times to get your ducts cleaned is after a rodent infestation.
Often times mice and or rats can make their way into your home through a small crack somewhere in your roof or foundation and then set up shop in your HVAC pipes/vents.
When you have a professional exterminator remove the rodent issue you still want to go the extra step and have your HVAC system cleaned well! The rodent urinates often and that mixed with their droppings can cause health issues in some people due to it getting airborne in your system.
