The EPA has recently stated that indoor air pollution can be up to 70 times more harmful than outdoor air pullution. Other recent news stories suggest the same trend. Since the air that flows through your house is supplied by your air duct system, it only makes sense to have the entire air system in your home cleaned and decontaminated on a regular basis.
According to the EPA, "These services typically — but not always — range in cost from $450 to $1,000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination."
The air duct cleaning process consists of 4 general steps. Although not every quality air duct cleaner will follow these steps in the exact order, you should ask your air duct cleaner if they include the following in their air duct cleaning process.
When is the last time you had your dryer vent cleaned? Similar to your air duct system, federal guidelines recommend having your dryer vent cleaned at least once every year. Lint can build up in the dryer vent and duct and cause airflow from your dryer to become dangerously low - which can cause overheating and lead to a fire.
A high-efficiency electrostatic air filter is the perfect companion to a freshly cleaned air duct system. These specialized filters remove 94% of the contaminants that pass through them. The average disposable air filter removes only 10% or less. If you've already invested in getting your air ducts cleaned, this premium quality filter will keep your system clean and free of irritants for years to come.
