Good ventilation is essential, so many buildings use an HVAC system. However, getting fresh air doesn’t involve installing an HVAC system alone; it requires cleaning. An air duct is an essential part of an HVAC system that produces fresh and clean air. They come in different sizes, materials, and shapes, and they require frequent cleaning. Many people know that their ducts need cleaning, but they don’t understand the process. Before delving into the five things to know when cleaning a duct, let us discuss air ducts and the importance of cleaning them.
What is an Air Duct?
An air duct is like a lung; they both pass air. It is a vital tube that connects an air vent with the HVAC system in your home. The HVAC system pulls the contaminated air in through a vent, then cools or heats the air. Then, the heated or cooled air comes out through an air duct to circulate through the house.
Air ducts are in different shapes, sizes, materials, and types. Some air duct types include a sheet metal duct, fiberglass lined duct, fiberboard duct, and air deflector However, the most popular among them are sheet metal air ducts.
Importance of Cleaning an Air Duct
Every HVAC system comes with an air filter to cleanse the polluted air being pulled in. However, air ducts start to gather dust, pollen, dirt, and spores as time goes by. This is bad for the house’s ventilation because it forces the air to spread all over the house.
Also, a dirty air duct forces the HVAC system to work harder than it should, causing damage to the system. So, cleaning the air duct is essential to maintaining good health for yourself and your HVAC system. However, there are crucial things to know before cleaning an air duct. Keep reading!
5 Things to Know When Cleaning a Duct
It’s Not a ‘Do It Yourself’ Job
You might consider cleaning your HVAC system’s ducts yourself on your free days. But air duct cleaning is a complicated process that needs the hands of a professional. Also, it requires special tools that we rarely find in homes.
Professional duct cleaners use powered brushes and high-grade vacuum systems to remove dirt from the HVAC system. On the other hand, a homeowner might use any tool they find, causing more dirt in the duct. Also, a regular person might not be able to source for other problems in the machine. But when you hire a duct cleaner, they check for other issues in the machine and fix them quickly.
Most Air Duct Cleaning Services are Unreliable
Proper research is necessary while searching for duct cleaning services for your air duct cleaning. While reputable duct cleaning companies exist, many scammers also use different methods. For instance, scammers could send emails offering to clean your system’s duct for less than $200. However, the average price range of a basic duct cleaning service is around $500-$1500.
Some scammers may claim to be members of the National Air Duct Cleaners Association. So, it’s best to contact the association to know if they are indeed members. This precaution saves you from losing money and putting your HVAC system at risk.
Dust on Registers Doesn’t Mean the Duct is Dirty.
Before an air duct gets dirty or clogged, the return register is the first thing to gather dirt. However, finding dust on the register doesn’t necessarily mean that the air duct is dirty. This information is essential because it’s one of the tactics that scammers use.
The air filter is directly behind the return register, absorbing most dirt to avoid getting into the HVAC system. Changing air filters frequently will save the duct from being too dirty. Also, we can easily clean the register with a brush and rag.
Some Duct Cleaning Chemicals Might Be Harmful
Besides removing dirt from the duct with tools, professionals sometimes use chemicals. However, most of these chemical products have not been approved by the agency. So, as the occupant, you can’t be sure of the safety of these chemicals.
Though these chemicals list cleaning HVAC systems as part of their uses, they trigger allergies. This considers them unsafe for use in the building. So, you must ensure that the duct cleaning service you have hired must use EPA-approved chemicals to avoid further issues.
Duct Cleaning Doesn’t Prevent Health Issues.
While duct cleaning is necessary, it doesn’t necessarily prevent health issues. Contrary to people’s belief that duct cleaning saves them from falling sick, it is mostly to maintain the HVAC system’s efficiency. We can inhale from other sources like pollen, mites, pet dander, and more. Though the duct might contain dirt and dust, it’s nothing compared to the dust from the carpets or furniture in our home.
So, duct cleaning might not make much difference except an occupant suffers dust allergies. Nonetheless, duct cleaning is an excellent idea.
Duct cleaning is essential; however, it’s not an everyday thing. When you notice mold on the duct or insects coming out from the HVAC system, your duct requires cleaning. However, it’s best to hire the services of professional duct cleaners to prevent further damage to the HVAC system.
