How to Know If Air Ducts Need To Be Cleaned 2?

We wish to enjoy the comfortable heated and cooled air throughout our home. That’s why we’ve got HVAC systems installed in our homes. However, we often forget our air ducts and fail to realize that just like other electronic items, our HVAC systems need proper maintenance. For an HVAC system to work properly, air ducts must be cleaned regularly. Clogged ducts can hamper the smooth operations of HVAC systems and even cause them to malfunction. Not only does your system suffer, but in the bigger picture it’s your health also that deteriorates.

A good question is how you know that it’s time for your air duct cleaning and air vent cleaning. Here are 12 signs that indicate that you should get your ducts cleaned.

What Is Air Vent Cleaning And Air Duct Cleaning?

Before we jump to the signs of dirty ducts, we should have a look at what is air vent cleaning and air duct cleaning. Air vent cleaning is the process of removing dust, debris, and other contaminants from the air vents and ductwork of a heating, ventilation, and air conditioning (HVAC) system. This service ensures that the air circulating throughout a building is clean and free from pollutants, contributing to better indoor air quality and system efficiency.

What Is Air Vent Cleaning

Air duct cleaning is a more detailed process than air vent cleaning as it involves a thorough cleaning of all the HVAC system parts, including the supply and return air ducts, registers, grilles, diffusers, heat exchangers, cooling coils, condensate drain pans, fan motor and housing, and the air handling unit housing.

Signs You Have Clogged Air Ducts

• Dusty Grills

The “grill” is an opening into an air duct in the wall. An HVAC system uses these vents to distribute cool or hot air throughout your house. When you see visible dust on these grills it’s a sure indication that your ducts need to be cleaned. Dust on these grills means that dust particles are settled into the ductwork and thus dusty air passes through the vents.

• Clogged Air Filters

Ideally, filters in your HVAC systems should be replaced at regular intervals so that they can continue to filter the indoor air efficiently. But if you are switching the filters too often this means there is an underlying problem. Constantly changing the filters means that they are clogged with dirt, dust, or debris. This is a clear indication that you need to inspect your air ducts for any clogs.

• Odd Ductwork Noises

When you hear strange noises coming from your HVAC other than its regular noise you should suspect that your ducts are dirty. We may not notice it instantly but one should be aware of this sign so that they can detect the strange noises in time. Your HVAC system may produce such sounds.

• Rattling Or Clanking

You may hear noises like rattling or clanking coming from HVAC system due to debris in the ducts. Also, dust and grime can cause components to loosen over time, leading to metal parts clanking against each other.

• Whistling Or Squealing

Accumulated dust and dirt can partially block air passages, creating high-velocity airflow through narrow openings, which causes a whistling sound.

• Banging or Popping

Banging or popping due to expansion and contraction of metal ducts caused by dust and debris.

• Humming or buzzing

You may hear this sound when dust and dirt accumulate on blow motors.

• Thumping

This noise is produced when dust and debris obstruct dampers or other moving parts within the ductwork.

• Rumbling.

This is when dirty ducts restrict HVAC system airflow.

• Pest Infestations

One of the obvious signs of air duct cleaning is when you can spot pest infestations in your home. These pests can introduce contaminants, damage ductwork, and create unpleasant odors. Infestations of insects, rodents, and other vermin in air ducts can pose significant health and safety risks. This is when it becomes critically important to schedule air duct cleaning.

• Air Duct Cleaning After A Major Renovation Or Construction

Completing a major home renovation project is an exciting milestone, but it can also introduce a significant amount of dust, debris, and other contaminants into your home’s HVAC system. Other than that, toxic chemical fumes can also persist in the air after construction or renovation. If you ignore these fumes and keep inhaling them, you’ll end up getting respiratory conditions. The best possible step you can take is to get an air duct cleaning service at the earliest so that you can breathe fresh and clean air free of any allergens.

• Surge in Electricity bills

If you monitor your energy bills you may know the average cost of your bills. However, if you see that your electricity bills have skyrocketed, then it’s time you check your ducts for any dust or dirt. With clogged ducts, the HVAC system uses more energy to maintain the heating and cooling temperatures. This excessive energy consumption is directly seen in electricity bills.

• Musty Odors From The Ducts

Normally, our homes don’t smell. And whenever they smell, we try to find its source. While odors like cooking odors can easily be identified but if you are not able to track some persistent smells in your indoor air it means something is wrong with your air ducts. In such a situation, you should go near the air register and try to get a whiff of it to confirm your doubts. For accurate detection and advice, you should contact a professional air duct cleaning technician.

• Frequent Allergy Symptoms

If you or any of your family members have sinus or other regular breathing issues, then you must be aware that people with such issues usually avoid a dusty environment as dust or dirt aggravate breathing issues. If you notice that you are frequently getting sick despite maintaining regular cleanliness in your home, then it’s time for duct cleaning. Dusty air ducts blow dust particles into your indoor air which causes your allergy symptoms to get worse.

• Evident Variable Temperature

Often when starting air duct cleaning our professionals ask this question to our clients before starting air duct cleaning.

“Did you feel some of your rooms feel hotter while others feel much colder?

They ask this question because clogged ducts obstruct air flow due to which the HVAC system blows air into your home with varying temperatures.

• If It Has Been a While

To keep your HVAC system in good shape you should keep a regular check on the air duct cleaning schedule. Usually, it is advised that you get air duct cleaning service every 3 to 5 years. Preventing air duct and HVAC issues is easy when you perform routine HVAC maintenance. Even if you sense an issue before the scheduled time, you should try to call a technician to handle the problem timely before it gets worse.

• Dirty Vents

Another evident indication is when you see dirt on all air vents in each room. If any part of your HVAC system is covered in dust especially vents, it means that ductwork is filled with dust. Dust can build up around blades and edges as air passes through the vents. As the air circulates, dust accumulates.

• Mold

Mold or mildew presence inside ductwork means that your HVAC system is shouting and calling for help! Moisture buildup inside air ducts is quite common, but the bothersome part about this is that a moist environment is an ideal place for mold growth. It gets worse when the same mold from ductwork spreads around and starts to grow in your house. Mold does no good to your health, your HVAC system’s health, and your property’s life. You may not be able to see it closely inside the ductwork, but having frequent breathing issues or other respiratory conditions will tell you about mold presence inside the duct. Inhaling mold spores can cause grave health problems.

• Dusty Home More Than Usual

If you see dust around even after cleaning your home several times it means that your HVAC system is blowing dusty air. This only happens when ample dust particles are trapped inside the air duct.

Will Air duct Cleaning Remove Smell?

Yes, air duct cleaning can effectively remove smells and odors from your HVAC system and indoor environment. Here’s how and why air duct cleaning helps eliminate unpleasant odors:

Eliminating Dust or Debris

Dust particles settled inside the air ducts break down they emit a musty or stale odor. Professional air duct cleaning involves powerful vacuums and brushes that remove accumulated dust, dirt, and debris from the ducts, eliminating a common source of odors.

Removing Mold and Mildew

Mold and mildew growth inside air ducts can produce strong, musty odors. Professional duct cleaning removes mold spores and mildew, reducing the musty odors they produce. Some services may also apply antimicrobial treatments to prevent future growth.

Cleaning Pet Hair and Dander

Pet hair and dander can get trapped inside ductwork, leading to persistent pet-related smells. Thorough duct cleaning involves cleaning every nook and cranny of ductwork. A technician removes all pet hair and dander fragments using a powerful vacuum.

Getting Rid Of Pest Infestations

Rodents or insects that nest in the ducts can leave behind droppings, urine, and nesting materials, which create unpleasant smells. Technicians can identify and remove any pests, nests, or biological contaminants that may be causing bad smells.

In addition to cleaning, some air duct cleaning services include the use of sanitizing agents that kill bacteria and neutralize odors.

Controlling Moisture and Preventing Mold Growth

When it comes to maintaining clean ducts, the EPA gives a handful of information to the general public. When advising necessary actions to take, it recommends ways to control moisture in the home and your air ducts. It emphasizes preventing moisture buildup inside air ducts as it is possible for biological contaminants to grow and spread throughout a home if moisture and dirt are present. In any type of air duct, moisture control is crucial to preventing biological growth.

Here is what you can do to control moisture:

1. Fix any water leakage or stagnant water.
2. Drain standing water from air handling units’ cooling coils by ensuring that drain pans slope toward the drain.
3. Humidifiers must be regularly serviced.
4. Air handling units should be designed so that maintenance staff can easily clean and maintain heat exchange components and drain pans.
5. A trained heating and cooling system contractor should remove and replace any fiberglass or other insulating material that is moist or visibly moldy (or has an unpleasant odor).
6. Steam cleaning or any other procedures that include moisture should not be used on air ducts.

Preventing Ductwork Contamination

Prevention is better than cure. We have heard it many times. It applies to HVAC ducts too. Here are some practical tips to help keep your air ducts clean and free from contaminants:

• Schedule regular maintenance for your HVAC system. Professional technicians can inspect and clean the system components, ensuring they are free from dust, debris, and mold.
• Replace your HVAC filters regularly, typically every 1-3 months, or as recommended by the manufacturer. Clean filters trap dust and other particles, preventing them from entering the ducts.
• Use dehumidifiers in areas prone to high humidity to reduce the risk of mold growth in the ducts.
• Promptly repair any water leaks in your home, especially around the HVAC system and ductwork, to prevent moisture from entering the ducts.
• Ensure your home has proper ventilation, especially in areas like bathrooms and kitchens, to reduce humidity levels.
• Have your air ducts professionally cleaned every 3-5 years or more frequently if you notice signs of contamination, such as dust buildup or mold growth.
• Make sure your ductwork is properly sealed to prevent dust, debris, and pests from entering. Leaky ducts can draw in contaminants from unconditioned spaces like attics and basements.
• Use air purifiers to reduce the number of airborne particles and allergens that can settle in the ducts.
• Regularly vacuum your home with a HEPA-filter vacuum cleaner to reduce dust and allergens.
• Regularly groom and bathe pets to minimize the amount of pet hair and dander that can enter the HVAC system.
• Frequently dust surfaces to minimize the amount of dust that can enter the HVAC system.
• Use proper ventilation when cooking, cleaning, or using products that release volatile organic compounds (VOCs).

By following these tips, you can help ensure that your air ducts remain clean, your HVAC system operates efficiently, and the indoor air quality in your home is healthy for you and your family. Regular inspections and prompt action can go a long way in maintaining a contamination-free HVAC system.  

Conclusion

Air duct cleaning can play a significant role in reducing allergens, improving indoor air quality, and maintaining your HVAC system efficiency. Duct cleaning helps you maintain a clean indoor environment so that you can enjoy living in a comfortable setting. Staying vigilant to take any hints for dirty ducts allows you to inspect your HVAC system for any issues.
