  General Facts about Indoor Air  
  • Americans spend 90% of their times indoors in homes, offices or schools, significantly increasing their exposure to allergens and irritants.
  • 87% of Americans are not aware that air pollution is worse inside the house than outside.
  • 48% of Americans are concerned about air pollution, according to a recent Gallup Poll.
  • Most susceptible to poor indoor air quality are the young, the elderly and those with chronic illnesses, allergies, asthma, and especially respiratory and cardiovascular disease.
  • Poor indoor air quality decreases motivation, productivity and performance among school children and office workers.
  • Short-term exposure to indoor air pollutants can cause immediate effects such as headache, dizziness, and allergies.
American Lung Association
  • The average American breathes 3,400 gallons of air each day.
  • 361,000 Americans die each year because of lung disease; it is responsible for one out of seven deaths.
  • More than 25,000,000 Americans are now living with chronic lung disease
  • Carbon Monoxide can be poisonous at higher levels, which are only found indoors and even healthy people may be affected. Carbon Monoxide exposure may also cause visual impairment, reduced work capacity, reduced manual dexterity, poor learning ability and difficulty in performing complex tasks.
  • American Academy of Allergy, Asthma, and Immunology
  • Total cost associated with hay fever in the United States is $3.4 billion.
  • Increased absenteeism and reduced productivity due to allergies cost companies more than $250,000,000 each year.
  • People suffering from sinusitis miss an average of four days of work each year.
Environmental Protection Agency
  • Studies show that indoor air quality is 2 to 5 times and occasionally 100 times higher than outdoor air. Indoor air pollution is among the top 5 environmental risks to public health

  • Three most important methods of improving indoor air quality are source removal, air cleaning, and increased ventilation.
  • Construction of more tightly sealed structures, reduced air exchange rates in ventilation systems to save energy, use of synthetic building materials and furnishings and the use of chemically formulated household and commercial cleaners, personal care products and pesticides has dramatically increased our exposure to indoor air pollutants.
  • Everyone is at risk due to poor indoor air quality
  Indoor Air Quality Services  
  What Does It mean?  
    Cleaner, healthier indoor air means that you have improved your quality of life by reducing your exposure to indoor air pollutants. Why is this important? Exposure to indoor pollutants can result in immediate health problems or health problems that may be experienced years later.
If you know the facts about Indoor Air Quality and how poor it can be, it makes sense that you take the necessary steps to clean and purify your indoor air.
The Evidence
In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. In fact, the level of air pollution inside a home can be 2 to 5 times higher - and occasionally 100 times higher - than outdoors! Other research indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.
  Take a look:  
  • As our exposure to chemicals in the air has increased over the years, the cases of cancer and asthma have also increased. In fact, asthma in children increased 86.8% between 1982 and 1995. - American Lung Association
  • Homes today have better insulation and are more tightly constructed. Due to this fact, less fresh air gets in and dirty indoor air remains trapped inside.
  • Indoor Environmental Asthma triggers include secondhand cigarette smoke, dust mites, mold, and pets. – EPA
  • Exposure to ETS (Environmental Tobacco Smoke) or second hand smoke is responsible for approximately 3,000 lung cancer deaths each year in non-smoking adults and impairs the respiratory health of hundreds of thousands of children. Source: EPA
  • Everyone is at risk to poor indoor air quality.
  • The quality of air we breathe, both indoors and out, has a great impact on lung health. - American Lung Association

  3 Basic Strategies - What is your next step to cleaner, healthier, indoor air?  
  According to the Environmental Protection Agency (EPA) there are 3 basic strategies to improve the quality of air inside.  
    Source Control
Usually the most effective way to improve indoor air quality is to eliminate individual sources of pollution or to reduce their emissions.
Another approach to lowering the concentrations of indoor air pollutants in your home is to increase the amount of outdoor air coming indoors.
Air Cleaners
There are many types and sizes of air cleaners on the market, ranging from relatively inexpensive table-top models to sophisticated and expensive whole-house systems. Some air cleaners are highly effective at particle removal, while others, including most table-top models, are much less so.

At Dominion Heating & Air Conditioning we have tailored our product and service offering to support the 3 basic strategies mentioned by the EPA.

Now that you have a basic understanding of the harmful effects of poor indoor air quality and what cleaner, healthier, indoor air really means, please take a journey to our full product and service offering we’ve established to help you purify your indoor air.

Our method utilizes a patented solution that agitates and vacuums dust and debris on contact. Dust and debris is collected in an EPA recommended HEPA filter to ensure full compliance with industry standards. In addition to dust and debris removal, we can provide an inspection of the cleaning that has been performed inside your air ducts.

It's important to note that you may need a solution that encompasses all of our services or you may only need 1 or 2 of the services we offer. You can schedule a free consultation with one of our associates to identify your unique indoor air quality requirements. We believe in listening and responding to your needs rather than trying to sell you a solution that may not fit your requirements.

  Our 2-Step Process  
  Step 1. Clean the Air Ducts and HVAC System

It is estimated that more than 70 percent of all indoor air quality problems involve the operation and/or maintenance of HVAC systems. A dirty HVAC system is a breeding ground for mold, fungi, spores, smoke, pollen, animal dander, and dust. When these particles become airborne in your air ducts and home, serious health problems can occur. Cleaning the HVAC system helps to remove these irritants, provides a cleaner pathway for air to travel, and delivers cleaner air for you to breathe.

Included with our Air Duct Cleaning Service, we provide Indoor Air Quality Conditioning that goes a step further than standard duct cleaning. Our IAQ Conditioning sanitizes and deodorizes the HVAC condensate drain pan, coils, and air ducts. This is not an "add-on" service, it's incorporated with every Air Duct Cleaning Service we perform.

Step 2. Maintain a clean system with Air Purification

What is air purification?
Air purification is the process of cleaning the air that circulates in your home. There are several ways air can be cleansed and filtered in your home.

  • Dominion Heating & Air Conditioning Whole House Air Treatment Systems
  • Whole House DeHumidification
  • Air Purification for Specific areas of your home

What To Expect

What is the normal price range for air duct cleaning?

The Environmental Protection Agency says that “duct cleaning services typically, but not always, range in cost from $450 to $1000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination” and type of duct material.

Consumers should beware of air duct cleaning companies that make sweeping claims about the health benefits of duct cleaning – such claims are unsubstantiated. Consumers should also beware of “blow-and-go” air duct cleaning companies. These companies often charge a nominal fee and do a poor job of cleaning the heating and cooling system. These companies may also persuade the consumer into unneeded services with and/or without their permission.

W hat To Expect From An Air Duct Cleaning Service Provider.

  • Open access ports or doors to allow the entire system to be cleaned and inspected. Inspect the system before cleaning to be sure that there are no asbestos-containing materials (e.g., insulation, register boots, etc.) in the heating and cooling system. Asbestos-containing materials require specialized procedures and should not be disturbed or removed except by specially trained and equipped contractors.
  • Use vacuum equipment that exhausts particles outside of the home or use only high-efficiency particle air (HEPA) vacuuming equipment if the vacuum exhausts inside the home.
  • Protect carpet and household furnishings during cleaning.
  • Use well-controlled brushing of duct surfaces in conjunction with contact vacuum cleaning to dislodge dust and other particles.
  • Use only soft-bristled brushes flex duct (Although flex duct can also be cleaned using soft-bristled brushes, it can be more economical to simply replace accessible flex duct.)
  • Take care to protect the duct work, including sealing and re-insulating any access holes the service provider may have made or used so they are airtight.
  • Follow NADCA's standards for air duct cleaning and NAIMA's recommended practice for ducts containing fiber glass lining or constructed

  Pitfalls To Avoid  
Avoid Manufacturers who sell air cleaners that produce Ozone.
  How is ozone harmful?  

The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath, and, throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. People vary widely in their susceptibility to ozone. Healthy people, as well as those with respiratory difficulty, can experience breathing problems when exposed to ozone.

Ozone generators that are sold as air cleaners intentionally produce the gas ozone. Often the vendors of ozone generators make statements and distribute material that lead the public to believe that these devices are always safe and effective in controlling indoor air pollution. For almost a century, health professionals have refuted these claims (Sawyer, et. al 1913; Salls, 1927; Boeniger, 1995; American Lung Association, 1997; Al-Ahmady, 1997).

  Are Ozone Generators Effective in Controlling Indoor Air Pollution?  

Some manufacturers or vendors suggest that ozone will render almost every chemical contaminant harmless by producing a chemical reaction whose only by-products are carbon dioxide, oxygen and water. This is misleading.

  Avoid Service Companies that will quote you a “Whole House Duct Cleaning” for $49, $88, $99, or whatever the latest gimmick seems to be.  

Consumers should also beware of “blow-and-go” air duct cleaning companies. These companies often charge a nominal fee and do a poor job of cleaning the heating and cooling system. These companies may also persuade the consumer into unneeded services with and/or without their permission. If you have knowledge of a practicing “blow-and-go” air duct cleaner, contact your local Better Business Bureau to report the company.

  Read the fine print on 'Whole House' Duct Cleaning Specials.  

Companies that offer a 'Whole House' special for a small fee ($39.95, $49.95) generally perform cleaning on 6-8 vents in your home.  Count your vents...More than likely, you'll have more than the advertised special.  If you do have 6-8 in your home, be prepared to be sold "add-on” services.
This is a typical gimmick to get you to buy in to a low price, and then be sold additional charges for additional vents as well as additional services.  All in all- you end up paying much more than the low price.  Remember friends, "You Get What You Pay For".
Indoor Air Can't Truly Be Cleaned unless it's circulated

Many of the popular "stick style" air purifiers claim to reduce allergens, pet dander, mold, dust, etc., but they do a poor job of cleaning your indoor air. Yes, they look good, and they are marketed well, but the value they provide is minimal. That's why a well known consumer products magazine reported that the leading stick style unit was "ineffective".  In fact, take a damp, clean, white cloth and dust off your television set weekly. Your TV captures dust particles, but how effective is your television at purifying your indoor air? Not effective at all!

  Take the test. Put a sheet of paper or a balloon near the "stick style" unit. You'll find that there's virtually no movement on the balloon or paper. Our educated opinion, do your research and you'll see for yourself. Remember, air must move through an air purifier for it to effectively purify your indoor air.  
  Now that you are educated on the Pitfalls to Avoid, you can buy from us with peace of mind and confidence.  We subscribe to only the finest products and services and yes, we too avoid those pitfalls!  We encourage you to schedule your free initial consultation and create a better quality of life for yourself and/or your family.
