Improve Indoor Air Quality with Professional Duct Cleaning

Let’s clear the air. Schedule professional air duct cleaning to improve your breathing, allergies, sleep, and asthma. We can remove up to 99.5% of the particles in your ventilation system, improving your HVAC system’s health as well as your own.

The Environmental Protection Agency reports that the concentration of pollutants inside of your home is often 2 to 5 times higher — and occasionally 100 times higher — than typical outdoor concentrations. And since we spend on average 90% of our time indoors, this is especially disconcerting.

The environmental condition inside of your home is probably the largest contributor to your health and wellbeing. A study by the IAQ Scientific Findings Resource Bank found:

In summary, building dampness and mold were determined to be associated with 30% to 50% increases in a variety of respiratory and asthma-related health outcomes and, for all health effects except development of the disease of asthma, the observed increases in these adverse health effects in damp or moldy homes were very unlikely to be the result of chance.

As new scientific studies and research comes out, we are becoming more and more aware of the harmful effects of indoor air pollution. A new study by the World Health Organization estimates that around 4.3 million people die a year from exposure to indoor air pollution.

“In particular, the new data reveal a stronger link between both indoor and outdoor air pollution exposure and cardiovascular diseases, such as strokes and ischaemic heart disease, as well as between air pollution and cancer.”

indoor air pollution-cause deaths.


Although many of these deaths are the result of poor ventilation and prolonged exposure to smoke and soot from leaky coal or wood cook stoves, poor indoor air quality affects us all.

Air Duct Cleaning

If you have a central air HVAC system, you will benefit from improved filtration and a professional duct cleaning every 7 years or so. Your air ducts are your home’s veins and arteries, with your HVAC system acting as the heart. As air passes through your dirty air ducts, dirt, dust, VOCs (volatile organic compounds), bacteria, viruses, and other indoor air pollutants get distributed throughout your home as well. Just imagine turning on your air conditioning and having dust and pet hair fall on your kitchen counter and food.

Test for Dirty Air Ducts:

To test if you need a duct cleaning, open up a vent/register and stick your flash camera in to take a picture. Then look to see if there is a lot of dust and dirt accumulation. If you are grossed out, you definitely need a duct cleaning.

For a more technical perspective on whether or not your home’s dirty air ducts need to be professionally cleaned, see this air duct guide by

By scheduling professional air duct cleaning, your system will run more efficiently and you and your family will feel a lot less sick.

Change Your Air Filter!

Many homeowners forget to clean or replace their air filters every 30-90 days. As a result, your air and air ducts get dirty, your HVAC system has to work harder, and your health and finances will suffer.

Solution: We recommend consulting this HVAC air filter guide to choose the best air filter for your home. The True HEPA filters generally provide the best filtration levels, claiming to remove up to 99.97% of airborne particles passing through the filter.

Don’t forget to vacuum and dust regularly, add a humidification system, and avoid household products that contain VOCs (volatile organic compounds). Always do your research before buying paint, cleaning products, craft supplies, beauty products, and air fresheners.

DIY Duct Cleaning

If you want to do some DIY improvements to your indoor air quality and airflow, you can go around to all your vents and registers and sponge them down and clean as far as you can reach. You can also use a vacuum hose to clean them even more. Even though this is better than nothing, a professional air duct cleaning takes 3-8 hours and uses industrial grade equipment to clean what you can’t see.
