Use a company that will provide a fair quote, based on the service that they will provide. Be weary of companies that advertise one price for a whole house. Think about it, would a painter paint any size house for one low price? Neither can an air duct cleaner PROPERLY clean the WHOLE house, no matter how many systems or air vents are in the home for one low price.
On the other hand there are many more air duct cleaning companies that will properly clean the air system and air ducts and use commercial negative air duct cleaning vacuums with at least 2,000 CFMs of vacuum power and utilize proper agitating tools to move the contaminates within the duct work to be captured with HEPA filters and contained by the air duct cleaning vacuum equipment.
Remember; think about your air system as the lungs of your home. Then consider the type of company that you want to handle your home’s lungs and your indoor air quality within your home. Have the complete air system periodically inspected for contaminated duct work and have it properly maintained so your Heating and Air System can provide your family with good air quality for years to come. Qualified air duct cleaners will follow strict standards set by the National Air Duct Cleaners Association. Allowing an unqualified contractor to clean your ducts could be worse than not having them cleaned at all. More particles could be broken up and released into your home or your HVAC system could be damaged.
Nowadays most homes have a central air system with connecting air ducting to move conditioned indoor air throughout the home. Over time, the air system and the connecting air ducting will accumulate dust and other contaminates, which can cause circulation of dirty and polluted indoor air through your home. Out-of-sight and out-of-mind health items that we don’t think much about are dirty air system and air ducts which could be the unhealthiest item in our home.
With your air system and air ducts in a constant cleaned state, you and those in your family can be in much healthier or at the very least minimize the symptoms experienced when the indoor air system was dirty and contaminated. In addition to improving health related symptoms, good indoor air quality in the home can lead to better breathing for deeper and undisturbed sleep. According to some doctors, improved undisturbed sleep can lead to a healthier life overall. While in some cases poor indoor air quality can be linked to asthma.
