Unfamiliar sounds, nesting material or signs of pests near a vent are reasons to take a closer look at the source of the problem. Cleaning the ducts and resolving a pest issue are different jobs.
What Might Prompt a Closer Look?
Scratching sounds, damaged vent covers, visible nesting material or unusual debris can raise questions about pest activity. These observations do not identify the animal or establish where it entered. Note what you saw or heard and where, without opening contaminated areas to investigate yourself.
An odor alone is not a reliable diagnosis. Describe it to the appropriate professional along with any visible signs and whether the concern is near a register, return opening or another part of the building.
Start with Pest Control When Activity Is Suspected
A qualified pest-control professional can assess activity and entry points. If rodents have accessed a heating or cooling system, CDC guidance recommends professional help. Addressing entry and the underlying pest problem is separate from deciding what cleaning the ductwork needs.
Do not sweep or vacuum suspected rodent droppings or nesting material. Follow professional instructions for the affected area. Read the CDC’s Rodent Cleanup Guidance for safety information.
Where Does Duct Cleaning Fit?
Once the pest issue and access have been assessed, tell our office what was found and what work has already been completed. We can review whether the request fits our duct-cleaning service or needs a different assessment.
Our standard cleaning scope is specific to the included supply and return ductwork, main trunks, furnace blower area and register boots. It does not establish that pest entry points are repaired, that an infestation is resolved or that every affected building material has been treated.
The EPA recommends assessing the actual condition and correcting underlying causes when considering duct cleaning. Cleaning is not a substitute for resolving a continuing source of debris or moisture. Read the EPA’s Guide to Deciding About Air Duct Cleaning.
What to Tell Our Office
- Where you noticed the signs or concern.
- Which systems or rooms may be involved.
- Whether a pest-control professional has assessed the issue.
- What you would like cleaned and any access restrictions.
You do not need to diagnose the problem before asking a question. Start with what you know so the next step fits the concern.
