Consumer Affairs Recommends Regular Chimney Inspections to Avoid Chimney Fires and Clogged Flues

Chimney fires and clogged flues can take their toll in lives and property damage, but the Montgomery County Division of Consumer Affairs (DCA) advises consumers that these tragedies can be prevented by regular chimney inspections and cleanings.”Having your chimney inspected is just as important as having your furnace and heating systems inspected,” said Ralph Vines, Acting Division Chief. ”There are a few simple steps you can take to ensure the safe and efficient operation of your fireplace.”

1. Contact a licensed/certified chimney sweep to have your chimney inspected. Signs of a dangerous chimney include cracks in masonry, poor updraft, broken flue sections, and creosote accumulation. Cracks can lead to chimney fires and further chimney damage. Clogged flues and poor updraft can increase the threat of carbon monoxide buildup in the home. Annual inspections are recommended, particularly for older chimneys.

2. Check to see if the chimney sweep is licensed. In Maryland, chimney sweeps who perform repairs are required to be licensed by the Maryland Home Improvement Commission. Make sure the sweep is licensed before agreeing to any repairs. Ask neighbors for referrals to chimney sweeping services. Check the company’s complaint record. Check DCA’s complaint records on their website montgomerycountymd.gov/consumer or by calling them at 240-777-3636. Check the Better Business Bureau’s records on their website www.dc.bbb.org or by calling them at 202- 393-8000. Also, ask the company for references, and find out how long it has been in business as well as how many years of experience the technician has.

3. Have the chimney cleaned on a regular schedule. This will vary from several times a year to once every several years, depending on how often the fireplace is used and what kind of wood is burned. Fireplaces used three times a week during the heating season will probably need to be cleaned at least once a year. Schedule an annual inspection, and the chimney sweep can advise on whether the chimney needs to be cleaned. Chimney sweeps are not required in Maryland to have a home improvement license if they only perform cleaning services, but it makes sense to use a licensed professional for cleaning, as well as for repairs.

4. Don’t make choices based on price alone. Some companies may offer a low price, but will only perform a cursory sweep of the chimney and no inspection, leaving you to clean up the dirt and with possible dangerous cracks that have not been discovered. Ask for specific details of the cleaning and inspection. Find out if the company is going to seal off the fireplace so that dirt and soot stay out of the home; if the technician will also inspect the furnace flue; and if the technician is going to vacuum the smoke shelf, the damper and the firebox. Make sure the company provides a written report, stating what was done and detailing any repairs needed.

5. Only burn dry, seasoned hardwood in the fireplace. This will cut down on creosote buildup so that less frequent chimney cleaning is required.

6. Consider installing a chimney cap. Caps can help prevent water damage and will keep animals out of the flue. Caps also reduce the danger of flying sparks.

7. Check the draft before lighting a fire, and make sure the damper is open. Don’t start a fire while an exhaust fan is running, as this can create a downdraft.

8. Never leave a fire unattended. Always remove ashes to a metal container and put them outside.

9. If you have a chimney fire, don’t close the damper. If you close it, the house may fill with smoke. Call the fire department and get everyone out of the house. For more fire safety tips check with the Montgomery County Fire and Rescue Service, 240-777-2448 or www.mcfrs.org.

DCA, the County’s consumer protection agency, investigates thousands of complaints each year involving automotive sales and repairs, new home purchases, home improvements, credit issues, retail sales, internet services and most other consumer transactions. DCA provides pre-purchase information to consumers, as well as speakers to the community on consumer issues. For more information and advice, call 240-777-3636 or visit DCA’s website at www.montgomerycountymd.gov/consumer.

Should You Have the Air Ducts in Your Home Cleaned?

David Bruce — Fri, 27 Nov 2009 21:30:46 +0000

Many homeowners ask themselves, “Should I have my home air duct system cleaned?”

You and your family spend roughly 1/3rd of your life in your home, which makes breathing clean, healthy air very important. The age of your home doesn’t really make a difference when it comes to performing this maintenance. If your home is new, this maintenance still needs to be performed. In fact, if you have just moved into a new house, it is the best time to have the air system fully cleaned. During the construction process there are many dust-generating tasks, and these dust particles – from sawdust to drywall gypsum – have most likely settled in you duct system. These are some of the most common eye and nose irritants and should be removed before you move into your new home.

If you have just purchased a resale home, it would be wise to consider having the air system cleaned to remove any harmful dust particles that have settled in the ductwork from previous years. Having the ducts cleaned in older homes may also remove odors and cooking particles built up from many years of use. Before occupancy of any existing house, you should at least change all air filters and clean all the air supply registers and return air grills. If you’re deciding whether or not to have your H.V.A.C. duct system cleaned, consider the following tips:

1) Think about health and air quality. Everyone has a concern about the quality of air we breathe. Many allergies, respiratory and breathing problems are related to particles and mites in the air. Regular changing of air filters in your home air system is a good maintenance practice and an important step to keep the air in your home healthy. Just as important is having the HVAC system serviced and cleaned periodically. Babies, young children and the elderly are the most susceptible to having respiratory problems caused by poor air quality.

2) How do I know if my home system needs cleaning? Every home heating and air conditioning system with forced air requires the air filtration media be changed regularly. Make it a practice to change air filters at least four times a year. If dirt is visible, you may need to change filters more frequently. Free airflow also lets the unit to run more efficiently.

3) When should duct cleaning be done? Every home environment is different, and the outside air quality also contributes to when duct cleaning should be performed. As a rule of thumb, I would suggest a cleaning every two to three years. Include your dryer vent and possibly exhaust fans in this cleaning. Consult a professional duct cleaning contractor for recommendations of services.

4) Can a homeowner do it themselves? A good portion of HVAC maintenance can be done by homeowners. If you are familiar with your forced air heating and cooling system, changing of the air filters is relatively easy. There are different grades of air filters available. Use the mid to higher priced filters, which collect finer dust particles. Also, if you are handy, you may want to attempt cleaning the air supply registers and returns. Simply remove the register, clean the grill and use a vacuum cleaner to clean inside the wall box. Repeat the same procedure for the return vents.

5) Are there others benefit to duct cleaning? Your home will be cleaner and require less dusting. Duct cleaning also helps remove odors from your household. The overall air quality will be healthier for you and your family.

How much does air duct cleaning cost?

David Bruce — Thu, 08 Oct 2009 04:15:00 +0000

How much does air duct cleaning cost?
Air duct cleaning usually costs about $400-$800 for an average size home – a home with 2 zones may cost $1000 or slightly more. If you are intent on getting your air ducts and ventilation system cleaned, get several quotes from reliable sources, preferably from references from friends or neighbors who have had the service done

How does a heating and air conditioning work?

The first step is to understand how your heating system and air conditioning work.

The typical residential home has a furnace (gas or oil fired, usually in the garage or basement — homes with 2 zones will have a second furnace unit, usually in the attic) that contains a heat exchanger and blower, and is connected to air ducts in 2 directions – one main set of trunks and supply line that send the hot or cold air from the furnace out into the rooms of the house, and another return duct that circulates returning air from the rooms back into the system, creating a constant flow of air.

From Maryland Air Duct Cleaning

Return registers in your home will simply look like grills on the ceiling or walls – you will never feel air coming out of these, but air is going into them and being fed into the return air duct down in the furnace.

The return air is fed through a filter to remove any particulate pollutants (or as much as your filter can handle – cleaning and replacing air filters regularly is more important for keeping your air clean), then it goes through the heat exchanger and gets blown back out into the supply trunk line and ducts and out through the supply registers you see around your house on the floor, walls, or ceiling – these supply registers are the ones that you will feel the hot or cold air spilling out of.

What do air duct cleaners do? Do air ducts need to be cleaned?
Behind the scenes of this cooling and heating system lies all the duct work. The duct work consists of the supply main trunk and then the branching off supply branches. The main trunk looks like a long aluminum rectangled tube, often wrapped in insulation of some kind. The smaller branch supplies are normally flexible metal tubes, looking much like the dryer exhaust hose you hook up to the back of your dryer.

How does air duct cleaning work? These tubes and ducts are what is being cleaned when someone cleans your air ducts – they remove all the register covers and insert vacuum scrubbing brush units down (or up) into the ductwork, cleaning and removing buildup as they go. They will also clean around the furnace unit and the filter areas removing whatever they find. How long does it take to clean the air ducts? – usually about 2-4 hours for a home with a single air handler. Most companies that offer air duct cleaning services promote themselves as something good for your health and the health of your family.

Cleaner air is supposed to help avoid respiratory problems and diseases, like allergies and asthma. They also suggest you should clean your air ducts every 3-5 years.

According to the EPA, if you don’t see a lot of mold or dust when you look into your registers, and no one in the household is suffering from allergies or unxeplained illnesses, you may be able to forego air duct cleaning. They even say that cooking, smoking, cleaning, and simply moving around your house likely causes more air pollutants than does dirty duct systems.

From the EPA website: “If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.”

Stupendous job. I have severe allergies and I am constantly cleaning and dusting to keep control of them. I had no idea that my air vents were that dirty or could even hold that much dust and dirt.

HVAC Duct Cleaning: Preventing Health Problems?

An Article from DoItYourself.com

There are a number of ads for companies that can do HVAC duct cleaning to prevent health promblems. But can HVAC duct cleaning prevent health problems?

About HVAC Duct Cleaning

The air that circulates through your house from your furnace and central air conditioning unit must travel through a system of ducts before reaching the final destination, which is the rooms you live in. Duct cleaning companies will come to your home and clean dust, mold, pollutants and debris from the components of forced air systems. Theoretically, duct cleaning results in better indoor air quality, creating a healthier living environment. There are several different methods for performing this operation which may include high powered vacuum cleaners and specialized tools. Sometimes a company will apply a chemical sealant coat to the inside of the ductwork after it is cleaned for continued maintenance.

Issues and Considerations

Every home is different and every family is different. Although there are guidelines created by the United States Enviromental Protection Agency it is difficult to generalize whether or not to have this service performed. The reasons to have your HVAC ducts cleaned may include:

allergy or health issues of people living in the house
visible accumulation of debris in the air ducts
visible mold in the air ducts
odor emanating from air ducts

If you are experiencing any of the above issues it is important to remember that while HVAC duct cleaning may help temporarily relieve the problem you still need to address the underlying issue. For example, if there is mold growing in your air ducts the removal of the mold does not begin to address how the mold got there in the first place. If there is mold in the air ducts it is probably in other locations of the house and a mold specialist should be called.

Another important consideration is the biocides or chemical treatments that may be used to seal the inside of the air ducts. Remember that these chemicals will be part of the air that you are breathing inside your home and could be detrimental to your health.

Preventing Health Problems?

The United States Environmental Protection Agency (EPA) states, “EPA does not recommend that air ducts be cleaned except on an as-needed basis because of the continuing uncertainty about the benefits of duct cleaning under most circumstances.” Each home has different needs, however, and you may decide to have this service performed. If this is the case be certain to fully investigate any claims your service provider is making. Claims about the health benefits of HVAC duct cleaning are unsubstantiated and should be reported to the EPA.

What to look for when Hiring an IAQ Consultant or Contractor

Studies have shown that most people spend 90% of their time in indoor environments. Indoor air quality (IAQ) issues impact the lives of people across the globe. Problems with poor air quality in buildings and homes can result in health concerns, liability issue, lost productivity, and decreased property values.

IAQ problems in non-industrial buildings such as homes, schools and offices are often caused by complex, inter-related issues. Diagnosing and fixing the sources of poor IAQ may require the professional expertise of one or more consultants or contractors. It is important that individuals be highly qualified to fully investigate, identify and/or mitigate the total problem according to recognized industry standards and guidelines. Verification of contracting or remediation work, if requested, should be conducted by an equally qualified third-party consultant.

Many firms are available today to help find solutions to IAQ problems. However, in most parts of the country the IAQ industry is not regulated. Therefore, it is important to make sure that you utilize a qualified professional.

The good news is there is an easy way to make sure that only qualified individuals and firms deal with these complex problems. The largest organization of trades and professionals dealing with IAQ issues is the Indoor Air Quality Association (IAQA). Since 1995, IAQA has delivered the industry’s most prestigious and respected IAQ and mold training programs. Many IAQA course alumni with sufficient experience and knowledge have also become certified by the American Indoor Air Quality Council (AmIAQ), prestigious, independent certification body for the industry. These trained and certified professionals are available to resolve your IAQ issues.

Prices Charged for Air Duct Cleaning

David Bruce — Sat, 19 Sep 2009 06:14:00 +0000

Air duct cleaning services in Maryland offering low prices, the lowdown
Many companies promise to clean air ducts for incredible low prices like $ 79 whole house coupons but don’t actually have the proper equipment, training or even the intention to provide real results. And what’s worse? Improper air duct cleaning can cause health problems in your family.
read about Bait and Switch here

Air Duct Cleaning Pricing
Depending on type of method that is chosen by the individual, the price for their air duct cleaning or furnace cleaning will vary. Not only does the method help to establish a basic price range, but these other factors will help as well: type of system, size of system, how long it will take to complete the duct cleaning process and how long the worker invests him or herself in the process of duct cleaning. Not all companies in Maryland take all of these things into consideration, but they do rely heavily on one or more of these topics in order to come up with an estimate. In addition, one may consider how difficult or easy it is to access a unit that needs to be cleaned, the climate of the area in Maryland that the house is situated in, and the level of focus or concentration that the worker requires in order to successfully complete his job.

Whoever may be performing the air duct or furnace cleaning process will likely also affect the price. Most often, the specific dollar amount can range anywhere from $450 to over $1,000. If a person has been able to set up a quality reputation in the field of duct cleaning, then odds are they will be able to charge a higher fee for their air duct cleaning services. However, their competition may not be able to charge as much, simply because they do not have the same clout that their duct cleaning competition has been able to create.

Suggestions for Choosing a Duct Cleaning Service Provider

To find companies that provide duct cleaning services contact the National Air Duct Cleaners Association (NADCA) at the address and phone number in the information section located at the end of this guidance. Do not assume that all duct cleaning service providers are equally knowledgeable and responsible. Talk to at least three different service providers and get written estimates before deciding whether to have your ducts cleaned. When the service providers come to your home, ask them to show you the contamination that would justify having your ducts cleaned.

	Do not hire duct cleaners who make sweeping claims about the health benefits of duct cleaning — such claims are unsubstantiated. Do not hire duct cleaners who recommend duct cleaning as a routine part of your heating and cooling system maintenance. You should also be wary of duct cleaners who claim to be certified by EPA. EPA neither establishes duct cleaning standards nor certifies, endorses, or approves duct cleaning companies.
	Do not allow the use of chemical biocides or chemical treatments unless you fully understand the pros and the cons (See “Unresolved Issues of Duct Cleaning).
	Check references to be sure other customers were satisfied and did not experience any problems with their heating and cooling system after cleaning.
	Contact your county or city office of consumer affairs or local Better Business Bureau to determine if complaints have been lodged against any of the companies you are considering.
	Interview potential service providers to ensure: they are experienced in duct cleaning and have worked on systems like yours; they will use procedures to protect you, your pets, and your home from contamination; and they comply with NADCA’s air duct cleaning standards and, if your ducts are constructed of fiber glass duct board or insulated internally with fiber glass duct liner, with the North American Insulation Manufacturers Association’s (NAIMA) recommendations.
	Ask the service provider whether they hold any relevant state licenses. As of 1996, the following states require air duct cleaners to hold special licenses: Arizona, Arkansas, California, Florida, Georgia, Michigan and Texas. Other states may require them as well.
	If the service provider charges by the hour, request an estimate of the number of hours or days the job will take, and find out whether there will be interruptions in the work. Make sure the duct cleaner you choose will provide a written agreement outlining the total cost and scope of the job before work begins. Source: US Environmental Protection Agency

HVAC System what exactly IS an HVAC air duct system?

David Bruce — Thu, 17 Sep 2009 17:51:00 +0000

What is HVAC?

Hvac – an acronym for Heating, Ventilation & Air- Conditioning

Heating and air-conditioning systems (including the air duct system) control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings. Heat pumps, which are similar to air conditioners but can be reversed providing both heating and cooling for a home. Heat pumps uses mechanical energy to pump heat “up the temperature scale” from a cooler region to a warmer one, and it does this by changing the pressure of a working fluid called a refrigerant. Heat pumps are more complex, and because they run in both summer and winter, they often require more maintenance and need to be replaced more frequently than traditional furnaces and air condition

Heat Pumps Fall Under Different Categories Such As:

* Air-Source Heat Pumps
* Ground Source (Geothermal)
* Water Source Heat Pumps

Who Install, Repairs and Maintains these Systems?

Individuals that specialize in heating, air-conditioning, and refrigeration, and they go by the terms technicians, mechanics and installers. They install, maintain, and repair systems. Heating, ventilation, air-conditioning, and refrigeration systems many times referred to as HVACR systems, these repair technicians may also be called HVACR technicians. Properly trained technicians repair, and maintain systems, but you will find that many have elected to specialize in installation, maintenance & repair, heating systems, refrigeration care, or air conditioning. Finding a technician who specializes is a brand or special equipment type is another great way to locate the right technician for the job. It always a good idea to find a technician that is familiar with our brand or type of system.

What Are the Component Units?
Heating, air-conditioning, heat pumps and refrigeration systems are a dizzying mix of many mechanical, electrical, and electronic components. These include components such as motors, compressors, pumps, fans, air ducts, pipes, thermostats, 4-way reversing valve, bi-directional expansion valve, thermal expansion valve
or ” TEV “, air conditioner compressor ,condensing coil, air filters, refrigerants, room thermostat, electrical switches, fuses or circuit breakers, blower fan, numerous switches, and more

Air Conditions Systems how do they Work?

Air conditioning or heat pump compressor which compresses low pressure refrigerant gas into a higher pressure, higher temperature gas. Usually the compressor is in the outdoor portion of an air conditioning or heat pump system. The compressor is basically a high pressure pump driven by an electric motor
A condenser or condensing unit: typically a condensing coil inside which high temperature high pressure refrigerant gas flows, and over which a fan blows air to cool the refrigerant gas returning it back into a liquid state (this transfers heat from the refrigerant gas to the air being blown by the fan).

A metering device which dispenses liquid refrigerant into a evaporator coil.
The metering device may be basically a thin section of tubing (a capillary or “cap” tube) or it may be a bit more sophisticated thermostatic expansion valve (TEV ) which includes a temperature sensing control that can open and shut the device against refrigerant flow an evaporator coil or cooling coil: usually the cooling coil is a section of finned into which liquid refrigerant is metered and permitted to evaporate from liquid to gas state inside the coil.

An air handler and blower unit which provides a fan, that blows building air across or through the evaporator coil. The air handler blower fan unit moves building air across the evaporator coil surface in order to condition building air by cooling it (this removes moisture from the cooler air).A duct system which sends conditioned air from the air handler into the supply ducts, and which then takes air from the ducts and returns it to the cooling system air handler.

Controls and features , which include a room thermostat, electrical switches, fuses or circuit breakers, condensate handling system, and air, filters.

Many Air Duct Cleaning Services offer cut rate bargain pricing based on vacuuming the air conditioning air ducts only. For such a low price those service companies are not likely to clean or even inspect the other important components of your HVAC air duct system, such as condensers, drain tanks, other places where condensation can collect and create conditions conducive to mold formation.

Vacuum collection alone does not clean the HVAC system. Brushes, air whips, “skipper balls” and other tools that agitate contaminants and debris scrub the surfaces within the air duct system and propels contaminants and debris into the vacuum collection device(s).

Anti-microbial chemical sanitizers are applied to the interior surface of the air ducts to control microbial contamination…but…before sanitizers are used, the system should be thoroughly cleaned. All anti-microbial chemicals used must be EPA registered for use in HVAC systems.

The purpose of residential air duct cleaning is to remove these contaminants from a home’s HVAC system to get the best indoor air quality.

Prices advertised on air duct cleaning, it it sounds too good to be true, it probably is. Maryland Air Duct Cleaning http://airwizcleanair.com

Air duct cleaning companies are not created equal.

How come you guys are so expensive? I’m looking at a coupon right now and this company’s offering to do the same work for less than half of Airwiz’ price!”

Dear Friends,

I’ve lost count of the number of times I’ve heard these words on the phone!

Well-meaning homeowners, about to be suckered by the oldest con in the world! An advertisement with a price that’s too good to be true, offered by a predatory business owner looking for an easy mark!

Strong words? You bet they are, and for good reason. There’s not a week that goes by that I don’t receive a phone call from someone who has been taken by these kinds of promotions. Not for pocket change, but for hundreds and hundreds of dollars.

I’ve prepared this report, to inform you about how this shameful practice works and hope it will make you a savvier consumer. Feel free to call me anytime with questions or comments.

Bait & Switch Tactics – “Oh the Tangled Web”

Bait advertising is an alluring but fraudulent offer to sell a service which the advertiser has no intention of providing. The primary aim of a bait advertisement is to obtain leads as to persons interested in the service offered. The “Bait” is a low price that they have no intention of honoring.

While the salesman was performing an “Inspection” the helper was getting the equipment set-up, making it very difficult for you to ask them to stop.

The estimate below was given to me by one or our customers. This is a carpet cleaner offering a “Whole House Duct Clean” for $89.00. Look at the total – $1,009.75!

When the customer said no, the tech called the “Boss” at his office. He said what a nice lady she was and asked if they couldn’t, “Find some way to give her a discount?”

The “Boss” and salesman argued for a few minutes and, unbelievably, offered to do the entire job for just $450. When she insisted they get out of her house, the now very un-friendly man demanded a $60.00 estimating fee before he would leave.

This is exactly how the system works. Every step is planned and rehearsed, and then the customer is expected to feel like they received a great deal with the “Discount” offered by the salesman.
