What is Indoor Air Quality?

Indoor air quality or IAQ is a term which refers to the quality of air inside your home or office.

You can no longer assume that indoor air is safe, clean or healthy. In fact, the Environmental Protection Agency reports that poor indoor air quality is one of the top five health risks in America and can be dramatically more polluted than outdoor air.

The primary factors affecting indoor air quality are:

  • Freshness – a building needs a reliable source of fresh air or it becomes stale. The solution to indoor pollution is “dilution”.
  • Dust, dander, pollen – air must be thoroughly and constantly filtered to remove these particles
  • Bacteria, viruses, mold, fungi – These “living” microbes can thrive in your home unless controlled and eliminated.

Poor indoor air quality can cause or contribute to the following:

  • Health issues
  • Aggravate allergies and asthma
  • Can cause structural damage to dwellings
  • Can decrease energy efficiency within the home

The American Lung Association recommends that the first line of defense against indoor air pollution is finding ways to keep the pollutants from being added to the air in the first place. This is known as source control. Appropriate ventilation with clean fresh air can also reduce levels of indoor air pollutants. Finally, while air cleaning devices can be useful, they are no substitute for preventing the air from getting dirty in the first place.

Indoor Air Quality Systems

Why are indoor air quality systems important?

The air inside the average home can be up to 100 times more polluted than outdoor air, according to the Environmental Protection Agency. Indoor air is literally filled with particles that can cause illness and aggravate asthma and other respiratory problems. Your entire home can be under attack by dust, pollen, animal dander, bacteria, viruses, fungi, and mold. These airborne invaders can actually live in your HVAC system, where they can multiply and cause damage to your family and your heating and cooling system.

Since we live in the whole house, it’s important that we work to keep all the air freshclean, and pure. The illustration below demonstrates how our Indoor Air Quality systems vastly improve the air quality of the whole house. Fresh air ventilationhigh efficiency filtrationUV light germicidal sanitation, and crawl space mold and moisture prevention are some of the indoor air quality systems that work to help protect the HVAC system, the entire home, and the family.

“Very easy to install, less than 30 minutes from start to finish. Customer’s sinus issues cleared up overnight.” – RJD Heating, MI

“The Duo-14 was very easy to install. It took about 20 minutes, give or take 5 minutes. What sparked my interest was not only the ease of installation, but the ease of bulb replacement. I have had one prior and it did keep smells down and kept my coil cleaner. I am sure this will do just the same or better.” — All Seasons Heating & A/C Inc., VA

“I am familiar with the technology that the Duo-2000 is using and I am very excited to experience the product’s performance. It was nice to feel the quality of the unit when I removed the unit from the package. The backer plate and cover are heavy gauge steel, (not a cheap plastic cover which is all too common these days). The installation was very simple, and took no time at all.” — Efficient Energy Enterprises Inc., MI

“The installation was very easy. It took about an hour or so to complete everything. My wife has asthma and also a bad cough for close to a month now and she has already started to notice an improvement in her breathing in the last week.” — P G Heating & Cooling, MI
