How To Choose

Do You Need Air Duct Cleaning in Alameda County?

You’ve noticed mold growing on some of your ducts. You suffer from asthma or allergies and have a difficult time breathing in your house. You have many pets with lots of fur and dander flying. You’ve tried everything from vacuuming to cleaning to air filters to working with your doctor. It might be time for an air duct cleaning. Air duct cleaning cleans your heating and/or cooling system – from the coils to the ductwork that runs throughout your home to the registers and grilles that send airto and from the heating or cooling source. A proper air duct cleaning addresses the entire system.

You no doubt have encountered many claims and received many coupons at your home in Alameda County, whether you live in Berkeley, Oakland, Fremont, Hayward, or San Leandro. No matter where you are looking, you want to be sure you are getting a complete cleaning from a qualified firm. Use the information below to help you decide on the best air duct cleaning company for you.

I’m Getting Some Fabulous Offers for Air Duct Cleaning in Alameda County
We’ve all got the coupons or flyers. Really cheap air duct cleaning that will change your life. As usual, what’s too good to be true usually is, and you’re sensible enough to realize it. As you move around your house in Alameda County, whether you live in Oakland, Berkeley, Fremont, Hayward, San Leandro, or Pleasanton, Newark, or Dublin, you may be asking yourself what an air duct cleaning will actually do for you. You’ve heard about concerns about indoor air quality – where pollutants can build up to greater concentrations than in the outdoors. Especially if you have asthma sufferers or allergies, or have lots of pets, you may be even more aware of air quality. Will cleaning your air ducts help resolve the problems?

Never work with a company that makes grandiose claims about dramatically improving your life. The research simply isn’t there to back up the claims. Air duct cleaning makes sense in that air ducts and your heating/cooling system send air through your home, air may have particles in it, and those particles may accumulate over time. So it makes sense to clean those areas once in a while, if you want to. Of course, if your HVAC system shows signs of mold, you should definitely have it cleaned. You should also search for the sources that allowed the wet in to start the mold, since it will merely mold again until you address the root cause. You should also have your ducts cleaned if vermin or insects are infesting them. And if you can see that dust or other material is clogging the ducts or dust actually gets spit out the registers, you are a good candidate for air duct cleaning.

When you are not sure whether you need air duct cleaning, you can ask the people who installed your heating and/or cooling system. They may be able to help you understand how sealed or unsealed your system is, and where possible contamination may enter. You can, of course, also ask an air duct cleaning company. They should be professional and responsible, but you must take care, since of course they also want to sell you something.

You should also avoid working with any air duct cleaning company that promises to do the job for a very low rate. If you look at the all the components that must be cleaned in a proper service, you will see that it is no small job. In addition, the company has overhead for the proper equipment, including the vacuum systems. A teaser rate may be advertised by the company, then charges piled on so that you end up paying a large amount. In 1996, the EPA estimated that a good air duct cleaning job costs between $450 and $1,000. Look for an air duct cleaning company that will provide a reasonable estimate, taking into account the size of your house and ductwork, access to the heating/cooling coils, and the entire system.

One other thing to avoid is a company that wants to schedule regular air duct cleanings. The frequency with which you decide to clean your ducts depends on who is living in the house, what animals are present, whether there is a change in conditions, such as a sudden increase in rain and subsequent water damage followed by mold, and the like. Since the benefits of air duct cleaning are not yet documented, you should have it done only when you need it. A good air duct cleaning company will understand this and not try to lure you in annual cleanings, or the like. Air duct companies themselves estimate that a cleaning lasts between three to seven years, a very wide range that makes setting up a schedule less than helpful. Also, if you have the misfortune to encounter a poorly trained technician, your heating and cooling system runs the risk of damage.

Having the Tools to Clean Your Alameda County Air Ducts
Once you’ve decided that you do want to clean your air ducts, and you are looking for a good air duct cleaner in Berkeley, Oakland, San Leandro, Hayward, or Fremont, there are several things you can look for.

Your air duct cleaner should have the proper tools to complete the job. This includes a vacuum to remove particles from the air ducts. The vacuum may be truck-mounted or may be portable. Some companies claim their truck-mounted vacuums are superior, but the National Air Duct Cleaners Association (NADCA), the trade association for HVAC cleaners, says that if their standards are followed, both truck-mounted and portable vacuums will do the job effectively. Truck-mounted vacuums do tend to be more powerful, but on the other hand, a portable vacuum can be brought into enclosed spaces, closer to the ductwork itself. If a portable vacuum is used that exhausts into the interior, it must have a HEPA filter to prevent particles from entering the interior space. Your air duct cleaner may also have a use for handheld vacuums and wet vacuums, and these should also have HEPA filtration. Your air duct cleaner might also need tools to cut into ductwork for better access. Inspection tools might include mirrors, a camera or closed-circuit television, or a periscope. Brushes are used to agitate the equipment and loosen dust. Some air duct cleaning companies may also use an air whip, an air gun, or a blowgun to loosen and move debris. However, fiber glass components can be damaged by these, so care is needed.

Having the Training to Clean Air Ducts in Alameda County
Just exactly what training your air duct cleaner needs to operate in Alameda County, whether in Berkeley, Oakland, Fremont, San Leandro, Hayward, Alameda, Union City, or Dublin can sometimes be a source of debate. For a proper cleaning, your air duct cleaner should have a C20 contractor’s license from the California Contractors State License Board. This is because the C20 license is granted for building, maintaining, and repairing heating, air conditioning, and ventilation (HVAC) equipment. In a proper air duct cleaning, the cleaning includes removing and cleaning the blower motor components, then reinstalling them. Since the blower motor is part of the HVAC system, the air duct cleaning company should be properly licensed. California contractors are required to include their license number in their advertising. You will notice that many air duct cleaning companies do not have a license. You should ask them why not and what components they include in the air duct cleaning that they provide.

In addition to the state license, it’s a good idea to look for air duct cleaning companies that belong to the National Air Duct Cleaning Association (NADCA). Members of the association will perform work to the association’s defined standards. The companies also pledge to hire at least one certified Air Systems Cleaning Specialist (ASCS).

Having the Professionalism to Clean Air Ducts in Alameda County
When you hire your air duct cleaning company in Alameda County, whether in San Leandro, Pleasanton, Fremont, Newark, Dublin, Berkeley, Oakland, Hayward, Alameda, or Union City, you should follow good guidelines for hiring contractors in general. Ask two or three contractors to provide an estimate for your particular house, not a general estimate. Ask how long the company has been in business, along with what licenses and certifications it has. California requires any company with employees to have workers compensation insurance, so check that the company has this, otherwise you can be liable if a worker is hurt on your property. Also check that the air duct cleaning company has general liability insurance and is bonded. California requires that its contractors have bonding. Ask for a written agreement before work is started. Ask how long the job may take and how many workers it may involve and make sure any quote covers those variables. Ask how the firm plans to protect any pets and the house during the cleaning process.

What Should I Expect From My Alameda County Air Duct Cleaning Company?
As you look for your air duct cleaning company, whether in Berkeley, Oakland, Fremont, San Leandro, or Hayward, it’s a good idea to know what to expect from a proper cleaning. Before beginning any air duct cleaning, the company should look to see if asbestos is present in the system. If it is, it must be handled according to regulations. An air duct cleaner should use tools, such as brushes or blowguns, to agitate debris, in concert with a vacuum that will pull the debris out of the heating or cooling system. Both the supply and return air ductwork should be included. The supply air ducts supply heated or cooled air to the rooms, while the return air duct takes air back to the heating or cooling devices, usually a coil. The supply registers, return air grilles, and any diffusers should be taken down, cleaned, and replaced. The supply and return plenums need to be cleaned. Check especially for moisture on the supply plenum, which can lead to mold. The supply plenum sometimes gets damp if condensation from the coil is not properly drained. The plenums are boxes that are close to the coil for the heating or cooling device and connect to the rest of the ductwork that travels throughout the house. The heat exchanger’s air-stream side should be cleaned, as should the secondary heat exchanger. The blower motor and its housing and assembly should be removed, cleaned, and put back, leaving no oil or other dirt on the blades and the blower compartment clean. The evaporator coil, drain, and pan should all be clean, and the coils should not be damaged or pushed together after the cleaning. Any air filters should be replaced with filters that match those recommended by the heating/cooling system’s manufacturer. The air cleaner should also be washed.

Why Is My Air Duct Cleaner Recommending Chemicals?
Sometimes, an air duct cleaning company will recommend using chemicals to clean or as a preventative, for example, to prevent mold. For example, the evaporator coil may be cleaned using chemicals and water instead of vacuuming. To prevent bacteria and fungus growth, some air duct cleaners may recommend a chemical. You must be extremely careful about allowing the use of such chemicals. Releasing them into the air in your home may cause problems for the occupants. In addition, all such chemicals must be registered for specific uses with the EPA, and they cannot be used for other uses. There are a small number of chemicals that are registered for preventing bacteria and mold. Besides being registered, the chemical must be able to be used as described on its label. For example, if the label requires rinsing with water, it should not be used, since it is not a good idea to introduce water into your ductwork. Note particularly that these chemicals can only be used on bare sheet metal. Much ductwork today includes fiberglass board, or is flexduct, which includes fiberglass, or is a metal pipe lined with fiberglass. In any case where fiberglass is involved, the material should be replaced if it has mold or other contamination, since there are not products approved to clean fiber glass.

If you do allow a chemical to be used, you should first ask the air duct cleaner to show you the mold or other microbial growth. You should be aware that just because something looks like mold, it may not be. If your air duct cleaner shows you material from inside your ducts and claims that it is mold, you should get it checked by a laboratory to prove that it is mold. The chemical should be shown to you, so that you can verify that it is approved for use in your situation. Using chemicals to kill microbes should be a last result. Consult with your air duct cleaner to find out if there is no way to simply remove the existing growth and then address the source of the problem – for example, improper evaporation drainage – to prevent it from recurring.

Some air duct cleaners may recommend a sealant to prevent dust and particles from escaping from the duct into the air. In most cases, these sealants do not provide an added value. First, they are often sprayed into the ducts, so that proper coverage is not guaranteed. In addition, a sealant may harm ducts built from fiberglass, reducing their ability to reduce noise and possibly even harming their fire retardation abilities and voiding the manufacturer’s warranty. Sealants for preventing dust from escaping are generally not recommended by the EPA, NADCA, the North American Insulation Manufacturers Association (NAIMA), or the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA). There are other sealants that may be appropriate when repairing damaged fiberglass insulation or fire damage in the ducts. A sealant should never be applied on top of wet, dirt, mold, or the like.

Steve Moore: A Fresh Opportunity

By James Florence, Diamond Certified Resource Reporter

DUBLIN — As a union tradesman, Steve Moore was in between projects when he decided to take advantage of a fresh opportunity. “Before I got into residential HVAC, I was working out of a union shop in San Francisco,” he recounts. “I had just finished a big project and was waiting around for the next job, as is often the case with union work, and in the meantime I started doing jobs for friends and family. It wasn’t long before I realized waiting for union jobs didn’t make much sense when I had people ready to give me work. Ultimately, I decided to leave the union and start doing residential HVAC work, and that’s what I’ve been doing ever since.”

Today, as owner of Moore Mechanical, Inc., Steve says his favorite part of his job is interacting with employees and customers alike. “I enjoy training my employees and watching them grow and be successful in the industry. Of course, I also get a lot of satisfaction from providing our customers with a high level of expertise and professionalism.”

A resident of Danville (where he lives with his wife, Wendy), Steve expresses his appreciation for the character of Bay Area work and life. “We’re very lucky in that we have both great weather and access to outdoor activities with the beach and mountains close by. From a business perspective, the Bay Area offers everything from excellent demographics to cutting-edge technology, so it’s great being able to offer the best systems to customers who appreciate quality.”

Outside of work, Steve engages in a variety of active pastimes, from outdoor pursuits to charitable activities. “I’m an avid cyclist and enjoy both mountain biking and road biking, the latter of which I do somewhat competitively,” he says. “I also do a lot of camping in the mountains with my family. Other than that, my wife and I are very involved in our church and like taking part in missions, both locally and abroad.”

In regard to a professional philosophy, Steve espouses the importance of the customer experience. “We’re committed to providing our customers with a great experience from start to finish,” he affirms. “This starts with the initial phone call and goes all the way through the job’s completion. We want each customer to feel great about the decision they made in hiring us, to the point where they can’t help but tell their friends and family about it.”

When asked the first thing he’d do if he were to retire tomorrow, Steve says he’d take his cycling hobby to a new locale. “I’d go for a week-long cycling trip in Italy. Of course, long-term, I would continue contributing to my business through training and teaching, and just make sure it continues to be healthy going into the future.”

What To Ask In Person

Ask Your Alameda County Air Duct Cleaner Some Questions in Person

You are most likely to encounter your Alameda County air duct cleaning representative in person when they come to your home to do an estimate. A visual estimate is the best way for the air duct cleaning company to know what is actually involved with your home. Some air duct sweeping companies may have you describe your system over the phone, in which case, the more you know about it, the better. But speaking in person with someone who will perform the estimate for your house is one of the best ways to get insight into the process.

Do you see any places where you may have to open up access to my ductwork or heating/cooling system?
If you do need to open access points, how will you make sure they are sealed after the cleaning?
How many workers do you think the job will take?
How long do you think the job will take?
Will you use vacuum cleaners in the house that don’t vent outside? If so, are they HEPA filtered?
Do you see fiberglass used in my heating/cooling system? How will you clean it?

What To Ask References

Hear Previous Customers' Experiences with Local Air Duct Cleaning Companies
It’s best to choose a Diamond Certified air duct cleaner because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from an air duct cleaner in Alameda County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

If you can’t find a Diamond Certified air duct cleaner within your area of Alameda County, you’ll have to do some research yourself. For example, it’s wise to call some references provided by your air duct cleaner. Keep in mind that references provided to you by local air duct cleaners are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because contractors will likely give you a few customers to call that they know were satisfied.

If you do call references, specifically ask for a list of the air duct sanitizing company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.
1. Were you satisfied with the air duct cleaning services this company provided? Why or why not?
2. Did the air duct cleaners respect your house and leave it clean after the air duct cleaning was completed?
3. Was there any damage to your heating/cooling system as a result of the air duct cleaning?
4. Did you have air duct cleaning chemicals applied to clean your system?
5. Did the air duct cleaning company recommend any chemicals for killing mold and bacteria?
6. Did you get a written estimate for the air duct cleaning services?
7. Was the quoted price what you paid? Or did the air ducting cleaners tack on fees?
8. Was your entire system cleaned or did they blow air through only the ducts?
9. Was the air duct sweeping crew pleasant and easy to work with?
10. Did the air duct cleaning team help you inspect the work after they cleaned?

How To Work With

Before You Hire an Air Duct Cleaning Company

Before you hire an Alameda County air duct cleaning company, whether you are looking in Berkeley, Oakland, San Leandro, Hayward, or Fremont, do a little homework. Know what kind of heating or cooling system you use. Is it a furnace and air conditioner or do you use a heat pump? Take a look at your ductwork. Are they bare metal pipes? Or are the pipes lined with fiberglass? Does your system use fiberglass duct board or flexduct? If you cannot tell, ask for help. Look for areas where there are large amounts of dirt that may clog the system, look for signs of mold, and look for signs of animal or insect infestation. Consider access to your system – make sure the cleaners can get to it. Be aware of areas where the air duct cleaners may have to create access.

Once You’ve Found Your Alameda County Air Duct Cleaner
After you’ve decided which Alameda County air duct cleaning company you are going with, whether you are in Oakland, Fremont, San Leandro, Hayward, or Berkeley, you need to work with them to get a good, written estimate. Ask any questions you have about how they will clean your heating/cooling system. If chemicals are recommended, ask to see the labels and make sure the chemical is used for the purpose described on the label and in the manner described on the label. Work with your air duct cleaner to protect your furniture and floors, as agreed. If chemicals are used, it’s wisest to clear all occupants of the house, including pets, during the application.

Make the Job Easier for Your Alameda County Air Duct Cleaning Company
You can make the job easier for your air duct cleaning company by being prepared. Know as much about your heating/cooling system as possible, so you can indicate what you want cleaned. Know the materials used in your system so you can make the appropriate choice, for example, knowing that you should not try to fix wet, moldy, or smelly fiberglass material, but should replace it. Work out with the air duct cleaning company how the furniture and floors will be protected, and do your part as agreed. Speak with your air duct cleaning representative about where access might need to be added. Be clear that you expect any additional access to be sealed after the cleaning. Being clear about expectations prevents frustration on both sides. If you cannot be on site during the cleaning, make sure the air duct cleaning company can contact you if anything comes up. Let the air duct cleaning company know at the start of the appointment that you would like to use their inspection tools to check after the cleaning is done.

Be a Good Customer

How Can You Be a Good Air Duct Cleaning Customer?
It's the contractor's responsibility to perform quality cleaning services on your home air duct system. But you can take a few easy steps to ensure the success of your air duct cleaning service, too. Here are a few simple steps you can take to be a good customer when hiring an Alameda County air duct cleaner.
- Be clear and upfront with the air duct cleaner. Let them know what you want from your air duct cleaning, the long-term outcome you’re expecting and specific ways they can satisfyyour expectations.
- Before you hire an air duct cleaner in Alameda County, restate your expectations and goals, and reiterate to the air duct cleaning representative your understanding of the agreement. Most problems with local aid duct cleaners occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
- Ask your air duct cleaner if you should call to check on the progress or if he will call you with updates.
- Be sure your service representative has a phone number where they can reach you at all times while they’re cleaning your air ducts. The work will move along more smoothly if your air duct cleaner can reach you for any necessary updates, questions or work authorizations.
- When your contractor contacts you, return calls promptly to keep the air duct cleaning on schedule.
- Pay for the air duct cleaning work promptly.
Why would you want to be a good customer? Air duct cleaners in Alameda County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

Check The Work

Check the Air Duct Cleaning Services Against the Invoice

Check the work against the invoice, making sure that all the pieces of the system are cleaned as discussed. You may also have prepared your personal checklist of the pieces to be cleaned. Try to get this checklist as part of the invoice. If not, go through the checklist to make sure all the pieces of the system were cleaned as expected.

Ask your air duct cleaning company about warranties. Many provide services with a guarantee of customer satisfaction. Ask what the warranty covers and what the process is for making a claim against the warranty.

Leandro, Hayward, or Fremont, did a good job, perform a visual inspection. Something must have led you to wanting your air ducts clean. Is that problem resolved? Look down the ducts to see if you can see dust or particles. A good air duct cleaning company will lend you the same tools they use to inspect, so that you can see the job is well done.

Many ducts today include fiberglass board, flexduct, or metal pipes lined with fiberglass. If you have fiberglass, make sure there are no rips or tears in the fiberglass. Look for mold or mold stains. Mold should be cleaned from metal pipes, and fiberglass material that had mold should be removed.

Prepare a checklist of all the components that you expected to be cleaned – from the registers, to the plenums, to the blower motor, to the evaporator coil. Ask the air duct cleaning company if each component on your list has been cleaned, and ask for explanations if they have not been cleaned. You should be able to shine a flashlight on the evaporator coil and see the light shine through to the other side. If the air duct cleaner had to make any access openings, they should be shut after the inspection and properly sealed. Finally, you should test that the system works after the cleaning – in both heating and cooling modes, if you have both.

Written Warranties

Ask for Air Duct Cleaning Guarantees in Writing

Most good air duct cleaning companies in Alameda County will offer some type of warranty on their services. This may be a simple warranty that guarantees all work was done as promised, while others may guarantee relief from allergies or a cleaner home.

If a warranty is important to you, make sure you discuss any warranties offered before the services are rendered, as it will most likely be impossible to convince your contractor to guarantee a job after the fact.

Regardless of what your warranty includes, all details of the warranty should be provided to you in writing.

This information usually includes:

The air duct cleaning contractor's name, physical address and license number.
Your responsibility if you place a warranty claim (i.e., if you have to pay for labor or materials, or if you are required to pay a prorated amount).
Terms, limitations and exclusions on the materials and workmanship.
If the garage storage system warranties are transferrable to the new owner if you sell your home.
What products and parts of the garage storage shelves are covered. This should also include whether they will replace or repair your garage storage system in the event of a product failure.

Top 10 Requests

Top Service Requests for Air Duct Cleaning

When it comes to air duct cleaning in Alameda County, be sure you have a trained professional complete a proper air duct cleaning process. You should make sure that all the components of your system are cleaned properly. These are not separate service requests, but points that should be covered by any proper air duct cleaning service as part of the standard air duct cleaning.

Clean Supply Ductwork
Make sure that the ductwork that send the air supply to the rooms in your house is cleaned.

Clean Return Ductwork
Check after the cleaning that the return ductwork, which sends air back to the heating or cooling device is clean.

Clean and Reset System Components
There are supply registers, return air grilles, and diffusers that are spread throughout your house as part of the heating and cooling system. These should all be removed, cleaned, and returned to their places during the air duct cleaning.

Clean Plenums
The plenums are boxes that attach the devices that heat or cool the air to the rest of the ductwork that spreads through the house. Both the return and supply air plenums need to be cleaned, and you should make sure the supply plenum in particular does not have moisture built up.

Seal Access Panels
Sometimes, your air duct cleaning professional will need to cut access panels to get at parts of the system to cool it. You should make sure the access panels are properly sealed after the cleaning.

Heat Exchanger Cleaning
Both the air-stream side of the heat exchanger and the secondary heat exchanger must be cleaned.

Remove, Clean, and Reinstall
The blower motor should be removed and cleaned, along with its housing and assembly. The blades must not have oil or other dust, nor should the blower compartment as a whole.

Clean Evaporator
The evaporator coil, pan, and drain must be cleaned. You should be able to point a flashlight at the coil and have the light shine through. If not, the coil is not clean.

Replace Air Filter
The dirty air filters should be removed and their replacements should match the efficiency rating recommended by the heating or cooling system’s manufacturer.

Wash the Air Cleaner
The air cleaner should also be washed as part of the air duct cleaning.

Q: I can see dust on the vents where air flows in my house. Do I need air duct cleaning?

A: You may see dust on the registers, or grilles, where air flows into and out of your heating/cooling system. This does not automatically mean that you should get your air ducts cleaned. You can easily vacuum the grilles clean, or other wise clean them. It is normal for the grilles to accumulate dust over time. Look for large buildups of dust in the vents themselves to determine if you need an air duct cleaning because of dust.

Q: Should I call an air duct cleaning company that is offering low price?

A: Air duct cleaning companies in Alameda County that offer very low prices for the whole house should be avoided. The rate is often simply a teaser, designed to get the unwary to sign up. The customer can then be hit with extra charges that drive the price up. In 1996, the EPA estimated air duct cleaning charges between $450 and $1000. This should give you some idea of cost.

Q: Does it matter whether the company uses a truck-mounted or portable vacuum to clean my air ducts?

A: When the air duct cleaning is done according to NADCA standards, either a portable or a truck-mounted vacuum can perform adequately. While a truck-mounted vacuum is usually more powerful, a portable vacuum may be able to be brought closer to the job itself. For all portable and handheld vacuums that exhaust into the house, it’s important to be sure they use HEPA filters.

Q: Does it matter what my air ducts are made of?

A: Fiberglass is present in much of modern ductwork, whether in the shape of fiberglass duct board, fiberglass lining for ducts, or flexduct. Older ductwork may be bare sheet metal. The distinction is important for several reasons. First, cleaning is performed by using a brush or other tool to loosen particles, which are then vacuumed up. The bristles on the brush must be soft when used with fiberglass, so that the fiberglass is not damaged. The air duct cleaning company must also be careful about using other tools instead of brushes – blowguns, air whips, and the like may not be appropriate for use with fiberglass. Secondly, once fiberglass is damaged by mold or water, it is recommended to replace it, rather than trying to fix or remediate it.

Q: Why is there mold on my ductwork?

A: Mold typically comes from damp that is allowed to linger. Damp can be a problem with a heating/cooling system if the coil is not properly drained. The coil is at the heart of the system and it is where refrigerant is changed from liquid to gas or vice versa. Changing the state of the refrigerant can remove humidity and heat or can bring heat in. The liquid/gas conversation can have condensation as a by-product. This condensation must drain properly so that mold does not take hold. This is one major source of mold.

Q: My air duct cleaning company showed me mold from my duct. I never noticed it. Are they right?

A: Some air duct cleaning companies will claim that you have mold in your ducts. You should ask for proof. The company may put a petri dish or similar collection device into the duct and then give you the resulting substance as proof that mold is present. Actually, no one can tell if mold is present visually. You should take the substance to a lab and get it tested to be sure it is actually mold.

Q: My air duct cleaning company wants to put a sealant in my ducts. Should I let them?
A: First, ask what the sealant is designed to do. Some sealants are offered with the claim that they will reduce the movement of dust and particles in the ductwork. You should not accept these sealants. First, the sealant will probably be applied by being sprayed into the duct. You cannot guarantee that the sealant will cover the entire surface properly. Secondly, for ducts with fiberglass, the sealant may harm their ability to resist fire and provide better acoustics. The sealant might even void the fiberglass manufacturer’s warranty.

Other types of sealants, such as sealants to mend fiberglass or for fire resistance, might be appropriate for use. Ask what the purpose of the sealant is, how it will affect your warranties, and how you will know that it is working.

Q: My air duct cleaner wants to spray anti-microbial chemicals in my ductwork. Is that ok?
A: You should approach the use of chemicals in your air ducts very carefully. Sometimes air duct cleaning companies recommend chemicals to fight bacteria or mold. First, you have to consider how you or family members might react to the chemical. Second, you should ask to see the chemical’s label. You should make sure the chemical is being used for one of the purposes identified on the label – otherwise it should not be used. You should also check how the label says the chemical should be applied. If the chemical cannot be applied as directed on the label, it should not be used. For example, if a water rinse is required, it cannot be used in ductwork because water should not be introduced. With caution, chemicals approved for it may be used on bare sheet metal surfaces.

There are no chemicals approved for use on fiberglass or flexduct, or any fiberglass material. If these materials have mold, they should be replaced.

Rather than using chemicals at all, you should search for the source of the problem and try to eliminate it. For example, mold can be eliminated if it is caused by poor condensation drainage if you fix the way the condensation is draining.

Q: What can I do to prolong the life of my air duct cleaning services?

A: Air duct cleaners estimate that a clean lasts three to seven years, depending on who lives in the house, heating/cooling usage, the local climate, and the like. Your best way to preserve a clean heating/cooling system is to prevent dirt and water from entering. Make sure the draining in the system is handled correctly. Change air filters annually (at the same time, it’s good to do carbon monoxide testing). Make sure that you are not missing filters, and that the filter holders do not allow air to pass around the filter. Vacuum the house regularly to prevent dirt build up. If you have a major renovation project in the house, seal off the registers and don’t run the system until you have cleaned up after the project. Make sure ducts are sealed and insulated unless they are in air conditioned spaces.
