Since air conditioners rely on air filters to clean the air and since evidence is lacking on the need for air duct cleaning, HVAC manufacturers do not design air duct to be cleaned . The EPA recommends that if you do choose to use duct cleaning services, that you only use it on ductwork made from solid sheet metal. However, in most homes today we use “flexible” duct that can be easily damaged by duct cleaning services.
If the air duct cleaning not done properly it can actually cause more harm to the air quality by releasing more dust into the home or particles of insulation from torn duct.
Once the air duct damaged you have no choice but to replace it. This will lead to even greater expense than if you had simply replaced the duct in the beginning.
The Truth About Duct Cleaning
So why don’t we offer duct cleaning even though we have customers ask us for this service on a regular basis?
Because we believe it’s a waste of money for our customers.
The truth, there no evidence that containing your ducts professionally cleaned would make your air any cleaner than it now. In fact, the EPA did a study to determine the results of air duct cleaning. Here what they concluded: “Duct cleaning never shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This seems because much of the dirt in air ducts adheres to duct surfaces. And does not necessarily enter the living space.”
things you can do right away to improve the air quality in your home:
Change your AC filter
Air-conditioning systems are always working to give your home that perfect temperature all year round. But while they’re cycling through all that air, they’re filtering out some of those common air pollutants. Eventually, their air filters fill up and stop doing their job. Not only does that cause trouble for your indoor air quality, it also wears down your AC system, which can lead to costly repairs down the road. So, be sure to change your AC filters regularly, or get an air conditioning service plan which normally includes a filter change – especially if you are allergy-prone or live in a metropolitan area with high levels of pollution.
Don’t forget about other air filters
Your AC filter isn’t the only thing working to keep the air clean in your home environment. If you really want to improve the air quality in your home, be sure to check the filters in your other household appliances. Your vacuum cleaner, clothes dryer and kitchen vents should all be inspected and maintained periodically. It’s recommended to clean or replace these common household filters every few months.
Check your air ducts
Air ducts are responsible for distributing hot and cold air throughout your home, providing a comfortable climate in every room. But ducts that are not installed properly or maintained can distribute contaminants from one room to another. Over time, dust, dander and even mold can accumulate in your ducts, reducing the overall air quality. Hire a professional to make sure your ducts are circulating fresh, clean air.
