How Important is my Indoor Air Quality?


The short answer; vitally important! The quality of your indoor air can be as much as 100 times worse than the outdoor air. That means pollutants, allergens, dust, mold and mildew can be circulating in your home affecting your family’s and pet’s health and well-being. Improving and maintaining your indoor air quality is vitally important to your family’s health.

Should I be Concerned if my Heating or Air Conditioning Unit is Loud While Operating?


A loud unit can mean poor airflow is running through the system. When airflow isn’t adequate for the size of the unit, it can result in a shorter life span for your system as well as higher energy bills and more expensive repairs coming your way. We can assess and recommend adjusts that can improve the noises you are hearing from your system.

How Can I Lower My Energy Bills?


There are a couple of things you can do to lower the amount of energy your system uses to operate.

Getting an appropriately sized unit for your house is a big way to reduce energy usage.

• Install a smart thermostat that automatically regulates the temperature and operating times of the system in accordance with your individual habits.

• Change your filters routinely (typically every 30 days).

• Having Quality Air professionally maintain your HVAC system can maximize its efficiency and longevity.

What are the Top 10 Things to Know About Mold?


Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma and other respiratory complaints.


  • There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
  • If mold is a problem in your home or school, you must clean up the mold and eliminate sources of moisture.
    Fix the source of the water problem or leak to prevent mold growth.
  • Reduce indoor humidity (to 30-60%) to decrease mold growth by venting bathrooms, dryers and other moisture-generating sources to the outside. Use air conditioners and de-humidifiers and increase ventilation by using exhaust fans whenever cooking, dishwashing and cleaning.
  • Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.
  • Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, that are moldy, may need to be replaced.
  • Prevent condensation: Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation.
  • In areas where there is a perpetual moisture problem, do not install carpeting (i.e., by drinking fountains, by classroom sinks, or on concrete floors with leaks or frequent condensation).
  • Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods.

How Do Molds Affect People?


Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing. Molds have the potential to cause health problems. Molds produce allergens (substances that can cause allergic reactions) and irritants. Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash.

Allergic reactions to mold are common. They can be immediate or delayed. Molds can also cause asthma attacks in people with asthma who are allergic to mold. In addition, mold exposure can irritate the eyes, skin, nose, throat, and lungs of both mold-allergic and non-allergic people. Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold. Research on mold and health effects is ongoing.

The above does not describe all potential health effects related to mold exposure. For more detailed information consult a health professional, your state or local health department, or the Centers for Disease Control and Prevention mold website.


Why is IAQ Important?


In recent years, comparative risk studies performed by EPA and its Science Advisory Board (SAB) have consistently ranked indoor air pollution among the top five environmental risks to public health. Good IAQ is an important component of a healthy indoor environment.

Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place symptoms occur. If the symptoms fade or go away when a person is away from the area, for example, an effort should be made to identify indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air coming indoors or from the heating, cooling or humidity conditions prevalent indoors. Failure to prevent or respond promptly to IAQ problems can cause increase long- and short-term health problems such as:

Cough
Eye irritation
Headache
Allergic reactions, and
in rarer cases, life-threatening conditions such as Legionnaire’s disease, or carbon monoxide poisoning

Indoor air problems can be subtle and do not always produce easily recognized impacts on health, well-being, or the physical plant. Symptoms, such as:

Headache
Fatigue
Shortness of breath
Sinus congestion
Coughing
Sneezing
Dizziness
Nausea
and irritation of the eye, nose, throat and skin

Symptoms are not necessarily due to air quality deficiencies. IAQ problems may affect a group of people or just one individual. In addition, IAQ problems may affect people in different ways. Individuals that may be particularly susceptible to effects of indoor air contaminants include, but are not limited to, people with:

Asthma, allergies, or chemical sensitivities;
Respiratory diseases;
Suppressed immune systems (due to radiation, chemotherapy, or disease); and
Contact lenses.

Certain groups of people may be particularly vulnerable to exposures of certain pollutants or pollutant mixtures. For example:

People with heart disease may be more adversely affected by exposure to carbon monoxide than healthy individuals.
People exposed to significant levels of nitrogen dioxide are at higher risk for respiratory infections.

Long-Term Effects
Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.

We can install a new system with state of the art advances or add an IAQ system to your existing HVAC system(s) at best in industry knowledge and pricing.
