It's a common sight these days to see HVAC units running full speed ahead 24/7/365. This has an effect on ducts, but no one remembers air duct cleaning. It's necessary for the removal of rodents, bugs, dirt build-up, and mold.
Mark J. Schmidt of Monday Mornings with Mark explains these benefits below of cleaning your air ducts.
Improve health: Rodents and bugs carry diseases that make us very ill. Getting rid of them reduces the likelihood of experiencing illness.
Mold and allergens: Cleaning ducts removes mold spores and allergens, which keeps the family respiratory ailment-free.
Odors: Smokers, hobbyists, cooks, and others create smells that waft through the ducts. Visitors smell the odors the most strongly because they're not used to them.
Cons
Makes little visual difference: The only way you can see inside ducts is to take off the register covers and look. Only professionals have cameras and lights to look further.
Scams: Beware of social media scams by very new members, members with no street address or other public record, and those who make impossible claims.
Air duct cleaning should be done every three to five years by HVAC professionals. Research the company, and then enjoy your clean ducts.
