Many homeowners wonder about how often they should have the air ducts in their house cleaned. There are many factors that will affect the frequency of cleaning. Having your air ducts cleans on an annual basis is a good standard. Although, there a few factors that will require you to have your air ducts cleaned on a more consistent basis.
If your home recently sustained water damage, it might be a good idea to have your air ducts cleaned or at least checked as soon as possible. Water that sits in the air duct will gradually start to build mold, which will release spores and toxins throughout your home. This is especially unhealthy if you or your loved ones have allergies.
Another factor that may require more frequent cleanings is if you or your family members suffer from allergies. If allergies are common in your home you will want your air ducts to be clean so you are not moving dust and other allergens throughout your home.
Another issue dealing with allergies is having pets, especially those that shed often and produce a lot of dander. Having multiple dogs and cats increases this effect. People with allergies and/or asthma, who also own pets, should consider more frequent air duct cleanings.
When moving into a new home it is also advised to have the air ducts cleaned. You can never be sure that the previous owners committed to best practices in maintaining high air quality.
Lastly, if there have been any recent renovations, the dust could have built up within the air ducts. Not only will this bog down the HVAC system from working properly, the dust will be blown throughout your home.
As long as you hire a trusted company to do your air duct work, you shouldn’t need to have them cleaned often. Only in these special occasions should you require more frequent cleanings.
