Mold growth inside a home may cause a number of problems from bad smells to health problems such as wheezing, sneezing, and irritation of the nose, throat, and eyes. It is not uncommon for mold to develop in the air ducts of a home, where it can remain hidden. The best thing you can do is be proactive in order to prevent the growth of mold in the air ducts. Use the following tips to keep the air ducts in your house free of mold.

Replace the Air Filter Regularly

Dust and debris can act as food for mold and mildew, and a dirty air filter can cause dust and debris to accumulate inside the air ducts. It is a good idea to get in the habit of checking your air filter regularly and replacing it when you can no longer see through it when you hold it up to the light. 

Insulate the Air Ducts 

Mold needs moisture to thrive, and water condensation can build up inside air ducts. This typically happens in the summer months when the house is warm and cold air is being pushed through the vents. When you have your air ducts insulated, they will not be as vulnerable to the warmth of your house, so water vapor is less likely to form when the air conditioner is running.

Run a Dehumidifier 

Humidity can play a big role in the growth of mold inside air ducts. If you live in an especially humid environment, or if you notice that there is often condensation in your home, a dehumidifier can be a great investment. Running a dehumidifier will remove a lot of the moisture from the air in your home, making the air ducts (and many other parts of your home) less prone to mold and mildew growth.

Hire Professionals

Many homeowners neglect to maintain the air ducts in their home, and this can cause horrible mold problems. If you want the peace of mind of knowing that your air ducts are in good condition and free of mold, make sure to have them cleaned and inspected regularly by an HVAC services company such as Allcounty Plumbing & Heating Corp. In the event that there is even a small amount of mold growing in the ducts, it will be found during an inspection so you can have it removed promptly. It is a lot easier to get rid of a small spot of mold than it is to deal with tons of mold growing throughout the air ducts in your home.
