What is Indoor Air Quality (IAQ)?

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.

Common examples of indoor pollutants include pet dander and dust mites, chemical vapors and odors, or germs, bacteria, or other living microorganisms.

Indoor air pollutants may cause serious health concerns, such as:

  • Nausea
  • Dizziness
  • Fatigue
  • Sneezing
  • Coughing
  • Eye and skin irritations
  • Congestion
  • Headaches
  • Allergic reactions
  • Respiratory tract infections
  • Asthma


The EPA – states that indoor air is one of the top five environmental health risks of our time and the levels of hazardous pollutants in indoor air have been found to be up to 60 times greater than outdoor air.

American College of Allergist & Asthma – States that 40% – 50% of all illnesses are caused by polluted indoor air.

The Center for Disease Control – Offers Guidelines for using equipment that we use on a regular basis to disinfect and clean the air.


Air Cleaner Installation Services

At Wm. Henderson Plumbing, Heating & Cooling Inc., we install many types of air cleaners to filter the air inside your home. We install whole-home air cleaners that can be installed on the air handler of your heating and air conditioning system. This enables the air cleaner to filter the air that moves through the air ducts so that it is cleaner once it is distributed throughout your home.

While air cleaners target small and large particulates, they cannot kill microorganisms. If you are concerned about viruses and bacteria, you may want to consider installing a UV germicidal light to work with your air cleaner. If you have questions, just call to speak with one of our indoor air quality specialists. We are sure to have a solution for your specific needs.


Humidifier Installation and Maintenance Services

Whole-home humidifiers can be installed for a number of reasons. Many homeowners who have indoor air quality issues, such as dry air in the winter, choose to install whole-home humidification systems. Air that is too dry within the home can cause the air to feel uncomfortable, and it may result in health issues, such as dry sinuses or breathing problems. Call us any time to learn more about how installing a humidifier can help improve the air quality inside your home.


UV Germicidal Lights

If you have already added an air cleaner and a whole-home humidifier to your HVAC system, you may want to think about a UV germicidal light installation to destroy harmful microorganisms. There are two main types of UV lights used with air cleaners, and they each use a separate type of technology to target different types of pollutants. Depending on the contaminants you wish to target, you may want to consider one or both types of UV light protection.

What Is Indoor Air Quality?

“Indoor air quality,” or IAQ, is a relatively new topic in environmental safety. While a lot of attention has been placed on outdoor pollution over the past few decades, the focus on indoor air quality is just beginning. The quality of a home’s air mainly has to do with the number of pollutants inside, but it’s also determined by humidity and ventilation levels. The U.S. Environmental Protection Agency has found that concentrations of pollutants can be up to 100 times higher indoors than outdoors. The American Lung Association estimates that most people spend 90% of their time indoors, so clean indoor air is very important.

How Can I Improve My Indoor Air Quality?

There are some basic strategies for outsmarting indoor air pollution:


The first step toward better indoor air is to identify the sources of air pollutants and remove as many as possible from your home. You can decrease the amount of dust and dirt in your home by cleaning and vacuuming at least once a week. You should also regularly wash bed linens and stuffed toys. If someone in your family is sensitive to fumes, you should safely store household products and use them only when necessary. If you need help determining if you have a problem with pollutants, contact your local Lennox dealer to evaluate your home and indoor comfort system.


Today’s modern homes are well-insulated and sealed to conserve energy, which means airborne pollutants have no way to escape. Healthy Climate® ventilation systems help remove allergy-aggravating particles and germs by exchanging stale, recirculated indoor air with fresh, filtered outside air.


Although cleaning and ventilating helps reduce indoor air pollutants, these simple fixes are not cure-alls. Some contaminants are so small that they may escape through the vacuum or never land on a surface. Healthy Climate® air cleaners and high-efficiency air filters capture even the smallest of particles and germs. Germicidal lights kill them. And a PureAir™ air purification system goes a step further; it removes particles, germs, and odors, and it destroys chemical vapors.


Improper humidity levels and high temperatures can actually increase concentrations of particles and germs. An icomfort Wi-Fi™ touchscreen thermostat or ComfortSense® programmable thermostat regulates moisture levels and temperatures to improve indoor air quality and enhance comfort.

What Are The Benefits of Clean Air?

Allergies and asthma are two health problems that can be helped with clean indoor air. When airborne irritants are removed, allergy and asthma sufferers often find relief from their symptoms. Even healthy people who have never suffered from allergies can benefit from clean air. Dust, smoke, and other particles float around in the air, causing your drapes and furniture to gather dust. By removing airborne dust particles, you reduce the amount of exposure your respiratory system has to them.

Can Indoor Air Be Hazardous To My Health?

Poor indoor air quality (IAQ) can be the cause of numerous health problems. Medical groups report that as many as half of all illnesses are caused or aggravated by indoor air pollution. Pollutants in your home’s air can cause dizziness, headaches, and nausea, plus aggravate allergies and asthma. Clean indoor air benefits everyone, even people who have never suffered from allergies. By removing airborne dust particles from the air, the amount of exposure the respiratory system has to them is greatly reduced.
