Frequently Asked Questions...
Are there any health benefits that come from HVAC system cleaning?
Heating, ventilation and air conditioning (HVAC) systems have been shown to act as a collection point for a variety of contaminants that have the potential to affect health such as mold, fungi, bacteria and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.
Will HVAC system cleaning reduce our home energy bills?
Research by the US EPA has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to break down, have longer life spans and generally operate more effectively than dirty systems.
How often should residential HVAC systems be cleaned?
Frequency of cleaning depends on several factors, not the least of which is the preference of the home owner. Some of the things that may lead a home owner to consider more frequent cleaning include: smokers in the household, pets that shed high amounts of hair and dander, residents with allergies or asthma and after home renovations or remodeling.
Why should I choose a NADCA member to have my air ducts cleaned?
NADCA members have signed a code of ethics stating they will do everything possible to protect the consumer and follow NADCA standards for cleaning. Air duct cleaning companies must meet stringent requirements to become a NADCA member.
What is the normal price range for the air duct cleaning service?
The Environmental Protection Agency says that duct cleaning services typically range in cost from $450 to $1000 per heating and cooling system. This price depends on the services offered, size of the system to be cleaned, system accessibility, climatic region, level of contamination and type of duct material. Consumers should beware of air duct cleaning companies that make sweeping claims about the health benefits of duct cleaning. Consumers should also beware of "blow & go" air duct cleaning companies. These companies often charge a nominal fee and do a poor job of cleaning the HVAC system.
