Dust coming out of AC vents can be worrying, but it is a problem you can solve. It happens when dirt and dust accumulate in the HVAC system. Dusty air is blown out of the vents, making the place uncomfortable to stay in and causing respiratory problems.
You will notice the dusty AC vents after home renovations in most cases. The dust settles in the heating and cooling machine, and although the vents filter this dust, some particles pass. Some dust also sticks on the AC vents.
Besides house renovations, there are other dust causes in the HVAC system. Luckily, you can clean the ductwork to ensure the particles don’t cause harm to your family. However, if you are unsure about your DIY skills, hire Clover Services to do the work. You must acknowledge that professional vent cleaners know the key spots to clean and the right tools to use.
Reasons for Dust Coming Out Of AC Vents
Homeowners whose houses have not undergone recent renovations could also notice dust on the AC vents. Here are some of the reasons for dusty ducts.
1. Leaky Duct
A leaky duct will allow dust into the system. Duct installers place these pipes on unconditioned spaces like the attic and ceiling. Naturally, these spaces accumulate dust and dirt, entering a leaky or disconnected vent.
Ducts disconnect from the air handler due to improper installation. When dust particles enter the system, the AC vents filter the air. Some dust particles are fine and will find their way out of the vents.
Besides, a leaky duct causes an increase in energy bills due to improper functioning. You will also notice hot and cold spots in the house, making the rooms uncomfortable to live in. To ensure energy efficiency and fresh air in the home, repair the leaky ducts.
2. Mold Growth
Sometimes you will notice black dust on the AC ducts, but it is not the usual dust. The black particles are mold, resulting from moisture in the HVAC system. Mold causes respiratory problems like asthma and increases allergies among family members.
You could also not see the mold particles, but a musty odor is a sign of mold growth on your AC ducts. Before cleaning the mold, first, check for water leaks on the ceiling or near the vents. Treating the cause of mold prevents future growth and provides a permanent solution.
Soot is a byproduct of burning a candle or using a fireplace, and it could be the black dust you are seeing on your AC vents. The vents suck air into the rooms for cooling, and the soot particles can be blown into the system. They block the ducts, causing inefficiency.
Check the filters to ascertain that the black dust in your AC vents is soot. The clogged filters will cause more damage to the cooling system, but you can replace them with new ones.
Solving the Dust Problem in AC Vents
Is dust coming from air vents in your house? When the dust accumulates on the AC vents, it blocks the ducts leading to the malfunctioning of the system. Besides, the dust causes allergic reactions to family members, and the dirty air makes the place uncomfortable to live in. Luckily, you can solve the dust problem by;
1. Repairing Leaky Ducts
If you have a leaky duct, hire HVAC system professionals to inspect the ductwork and identify the leaking parts. The professionals will use temporal seals to block the small holes or reconnect the duct to the air handler. However, if the damage is too significant, you could be forced to replace the entire duct.
2. Clean Moldy Areas
Suppose the dust coming out of AC vents in your home is black; it is mold. You can remove the mold using a soft brush and clean the vents. Alternatively, hire professionals to clean the entire system and remove the moisture.
The professional cleaners also use chemicals to kill the mold and prevent future infestation. However, homeowners should ensure the chemicals have less-harsh ingredients to avoid allergies.
3. Avoid Using Scented Candles
Scented candles are mainly manufactured from petroleum jelly and vegetable oils, and they produce a lot of soot. To avoid soot accumulation on the vents, use natural candles. Alternatively, you can use other methods to make your home smell good.
Also, keep the candles away from the vents. It prevents soot particles from being sucked directly by the AC, reducing the chances of particles on the vents. Besides, you also reduce the amounts of regular repairs, lowering duct maintenance costs.
4. Improve Your AC Vent to a Higher MERV Rating
Minimum Efficiency Reporting Value, MERV, measures the efficiency of the filter. High MERV ratings on the air filter indicate higher efficiency, and these filters are good at catching dust particles.
Efficient air filters have a MERV rating of 8 and above. You can also seek help from HVAC professionals before buying the MERV filter. The experts know better about these filters and advise you on the best quality. They will also fix the filter correctly in your house to save time and cost for future regular repairs.
5. Regular Cleaning Of the HVAC Vents
Depending on your home’s cleanliness, you can schedule HVAC cleaning twice a year. Removing the dust particles regularly prevents accumulation and maintains clean air in the house.
However, avoid DIY vent cleaning if you don’t have the right tools and expertise. Using hard brushes and chemicals could damage your vents, forcing you to replace them, which is expensive. Also, dust and clean your carpet regularly if you have pets in the house.
Is dust coming out of air vents in your HVAC system? Dust on the HVAC vents can be disturbing. The dust causes many respiratory disorders and makes the rooms uncomfortable to live in. The dust can also cover the vents and reduce the entire system’s proper functioning. If you are unsure about cleaning the AC vents, hire a professional. They will ensure safety for your system. Besides, the experts have insurance that caters to any damages during the cleaning process.
