Certifications are essential in some markets and industries.
Whenever a business starts selling food in any capacity, at least one person on site has to get yearly certifications from the health department.
It’s about food handling, cleanliness, and sanitization. Otherwise, the health department has no way of knowing if there are no people on site who have any clue what they’re doing with food safety. It’s the same with contractors as well. You wouldn’t want to hire a random home building company to erect a house for you if you can’t verify if the owner is licensed and certified, would you? However, unless you were taught this from a parent, friend, coworker, or associate at some point in life, you would probably have no clue to look for licenses and certifications when you hire companies for home services. There are shady people out there offering ductwork cleaning without having the proper training to do it safely. This is dangerous, because improper ductwork cleaning procedures will both damage your ventilation system while contaminating the rest of your house. Whenever dirt and microbial content is scrubbed off metal ductwork, it will easily circulate into every room of the house if it isn’t properly vacuumed during the cleaning process. Safe ductwork cleaning companies will pursue accreditation on a regular basis, otherwise you need to look for a different company. Sometimes heating and cooling contractors offer their own ductwork cleaning services if you don’t find a business that is devoted primarily to ventilation systems. In this case, as long as the HVAC supplier is certified for ductwork cleaning, they should be a possible option when looking at reviews.
