Have you noticed dust coming from the vents in your home when you turn on your HVAC unit?

If so, it’s probably because your air ducts are dirty—and dirty air ducts can cause a list of problems in your home. 

However, routine cleaning of air ducts and generally maintaining your HVAC system will not only prevent these problems but can also increase energy efficiency and improve the air quality in your home. Because you don’t see the inside of your air ducts every day, it may be difficult to tell when your system could use a cleaning. 

To help you relax and take a deep (clean) breath, the Vent Medics experts have five signs to look for when determining if your HVAC system needs cleaning.

Dirt and Debris Around your Vent

Let us begin with the obvious. The National Air Duct Cleaning Association’s (NADCA) rule of thumb is that dust around ducts and air returns indicate a problem. Similarly, if you notice dust and debris around your vents, your HVAC system likely has high amounts of contaminants circulating through the air ducts. 

When this occurs, it’s time for a cleaning. Amazon sells a vent cleaning brush, but experts will tell you that this is only a band-aid fix. If dust is lodged within the vent system itself, reaching deep inside requires more tools than a brush and some vent and duct cleaning solution. 

Spikes in your Energy Bill?

In extreme cases, debris can get into your HVAC system and cause some issues. The Washington Post debunked the high energy usage that dust and debris could cause. 

More energy waste comes from leaking ductwork, forcing your HVAC system to run longer and use more energy.

Getting your air ducts cleaned with expert services allows cameras to inspect the system and see problem areas. When your HVAC system is clean—and leaks fixed—your system doesn’t have to work as hard to keep your home at your desired temperature, so you’ll use less energy and improve cost-effectiveness.


If you or your family members are having unexplained or worsened allergy, sinus, asthma, or other respiratory problems, excessive allergens, and pollutants in your HVAC system may be the cause of the problem. 

According to NADCA, your HVAC system pulls contaminants through your home five to seven times per day, exposing you to allergens each time. Cleaning your air ducts can significantly improve the health ailments triggered by low indoor air quality.

Mold Growth

Mold can grow anywhere, and it’s incredibly familiar if you live in a humid climate. Mold exposure in homes has been linked to many health issues like throat irritation, eye irritation, coughing or wheezing, and in some cases, skin irritation. People with mold allergies may also have more severe reactions. Mold grows and spreads through spores, which can be picked up by your HVAC system and circulated your home, promoting further growth. 

If you see visible mold growth inside your air ducts, other components of your heating and cooling system, or elsewhere in your home, contact an indoor air professional.

Factors that Increase the Need for HVAC Maintenance:

  •      Pets
  •      People with allergies or asthma
  •      Cigarette or cigar smoke
  •      Water damage contamination that has impacted your HVAC system
  •      Home renovation or remodeling projects

How Much is Air Duct Cleaning?

The average air duct cleaning for most homes costs between $300 and $500, with the price affected by factors like the home’s size, the number of ducts, and their configuration. However, you can talk to a duct cleaning expert and receive a free quote at Vent Medics
