How you can prevent air duct contamination

We’re going to provide you with a series of guides to make sure that you are ready and prepared to prevent air duct contamination.

Prevent dirt from entering the system

Prevent ducts from getting wet

There should be no moisture present in the ducts as this could be the cause of biological growth such as mold in your air ducts. Controlling the moisture is an effective way to prevent this from happening.

Moisture can enter the air duct system from leaks or if the system was not properly installed. Condensation, which occurs when the surface temperature is lower than the dew point temperature of the surrounding air, is a factor in moisture contamination in the system.

It is difficult to control moisture but is achievable through these steps:

Use efficient air filters

Every home deserves an efficient air filter to make sure that the air ducts are not contaminated. Quality air filters take as much stale air out of the rooms for a better flow and freshness. Not only is freshness assured but air filters can help to remove the small particles that are in the air near them. Think of air purifiers. Air purifiers are used to literally purify the air in your surrounding, so a good filter for a duct would do the same.


Your home is your safety and sanctuary. It can’t be any of that when your air duct is displaying signs that it needs to be cleaned. Making sure that your air duct is clean and avoiding contamination is a way to show yourself that you care about your health and your home. Not to mention, the cost that would go into having the HVAC system fixed or replaced if it’s not maintained and cleaned regularly.

Do yourself a favor and get that air duct checked and cleaned. It’s a tedious job but you’ll thank us later for making you do it.
