Signs That Your Air Ducts Need Cleaning

Updated: Mar 14, 2023

Air duct cleaning is important. Here are some warning signs to help you determine if it's time to clean your air ducts:

Musty Odor

If you notice a musty odor in your house, you may have mold growing in your air ducts. Because the vents are so large, mold can sometimes grow unnoticed.

Putting a flashlight up to the vents is the easiest way to check if this is the case. If you notice any discoloration or significant buildup, you should consider calling in a professional to clean the air ducts.

Your house is dusty

The air ducts in your home may need cleaning if you notice that it is dustier than usual. Dust built up in the air ducts can cause dust to accumulate in your home.

Dust visibly coming out of your vents

It is an indication that your air ducts need to be cleaned if you notice dust or other debris coming out of your vents.

You or a family member has allergies or asthma

If you or a family member suddenly develops allergies or asthma, it may be necessary to have your air ducts cleaned. This can often mean that your filter needs to be replaced and that your ducts or coils have grown bacteria or other deposits.

Clogged Air Filters

If your air filters are clogged, the AC system pushes cold or hot air harder and less efficiently into your home. Also, if the air filter has a lot of dust or debris, it's time to clean the air ducts.

The easiest way to prevent this is to regularly clean or replace the air filters.

You recently underwent home improvements or renovations.

Cleaning the air ducts is a great idea if you have recently renovated your house. Ensuring the cleanliness of the air ducts is very important, as dust and other toxic substances can be released into the air during the renovation. This is especially true when cutting wood or drywall inside of the home.

Your air ducts haven't been cleaned in a while

If it's been a while since you cleaned your air ducts, you should get them cleaned. Over time, dust and other pollutants can build up in your air passages, reducing the quality of the air you breathe.

If you are experiencing any of these symptoms, it may be time to clean your air ducts. Don't be afraid to take action, because it can greatly improve the air quality in your house and, as a result, the health of your family.
