Air Quality and Your Health

Air quality is an important issue for many people simply because of the negative health effects associated with breathing dirty air. In many cases, indoor air that is contaminated can irritate your eyes, nose and throat or cause headaches and fatigue. Long-term exposure to dirty indoor air can cause respiratory disease, heart disease and even cancer. Indoor air pollutants affect everyone differently, making it difficult to identify and eliminate the specific source. Professional air quality testing can help uncover pollutants in your home or business.

Sources of Indoor Air Pollution

Most people correctly identify indoor air pollution with tobacco smoke or pet dander, but there are also harmful chemicals and gases that are released from common household cleaners and spray fresheners. In addition, some building materials or insulation can be dangerous and outdoor sources like radon or pesticides can leave harmful residue behind. Learn more about common indoor air pollutants and how they impact your health.

Mold and Mildew

Mold and mildew grow in overly-humid environments. Because we have a tendency to keep our homes tightly sealed, places like basements and cellars are all prone to mold infestation. Mold is an allergen that aggravates many people, causing eye, nose and throat irritation, shortness of breath, coughing and asthma attacks.

Particularly in the spring and summer, pollen is a serious problem for many allergy sufferers. Symptoms of a pollen reaction include sneezing, watery eyes, congestion and coughing. Pay attention to the pollen count in your area, and take extra precautions at home when levels are high.

Pet Dander

Pet dander is a particularly tricky problem in many homes because its small size makes it very hard to filter out effectively. For people with sensitivities to it, pet dander can cause home comfort problems including respiratory infections, eczema, and itchy and watery eyes.

Dust Mites

Where there’s dust, there are dust mites. Invisible to the naked eye, dust mites that thrive in humid environments can cause runny noses and itchy eyes, and can also trigger asthma attacks.

Volatile organic compounds (VOCs) are present in paints, pesticides, certain cleaning products and other household items. VOCs evaporate in water and can cause symptoms ranging from mild irritation to kidney failure.

These indoor air pollutants are all common substances that are likely present in the majority of homes. While you may not be able to eliminate all sources of air pollution, you can take steps to reduce their impact.

Our air quality experts take steps to remove pollutants from your home and purify indoor air. We make it healthier and more comfortable to breathe with solutions like air filters and cleaners. RSC offers the following air quality services for residential customers.


Once we have determined the source of your home’s high humidity levels, we will make recommendations to bring this property-damaging health hazard under control. Our solutions may include:

  • Dry itchy skin
  • Dry eyes
  • Nose bleeds
  • Cold and sinus issues
  • Lack of comfort
  • Static electric shock
  • Damaged trim and woodwork

We can help reduce these issues by installing a whole house humidifier to automatically bring your humidity to the perfect level. Our home comfort experts will evaluate your house to determine the appropriate type and size of humidifier.

Particulate Reduction

The average person spends about 90% of their time indoors and inhales about eight thousand liters (or about 2,100 gallons) of air per day. At that rate, we breathe about seven million particles, twenty-eight million bacteria, and countless gas molecules every hour! Those particles, biologicals and gases can promote allergies, asthma, and more serious illness if not prevented, diluted or filtered.

At RSC Heating & Air Conditioning, we offer air filtration units that remove up to 95% of particulates 0.3 microns and larger. To give you some perspective as to the efficiency of our systems, the dust you can see floating in the air is larger than 10.0 microns.

Commercial Humidifiers and Dehumidifiers

Dry office air can cause discomfort and even make it harder to breathe, especially for employees with conditions such as asthma. Invest in a commercial humidifier to balance the humidity levels throughout your entire building.

Overly humid air can cause as many issues as dry air since it encourages mold and mildew growth. If you are experiencing high humidity levels, we can recommend a dehumidifier to remedy this issue.

RSC Heating & Air Conditioning is a Carrier Factory Authorized Dealer. We primarily sell Carrier humidifiers and dehumidifiers for commercial buildings, but we can also service and repair any brand of HVAC equipment.

Commercial Indoor Air Quality Testing

There are many potential contaminants that could impact your commercial building’s air quality. These include mold, bacteria, pests, radon and volatile organic compounds (VOCs). Any combination of these may result in “sick building syndrome” where the air quality is so poor, it causes health issues for employees.

If your employees are getting sick or you want to be sure there are no hidden health risks in your building, commercial indoor air quality testing is the solution you need. We can test for a wide variety of pollutants and provide a comprehensive report on air quality. Our technicians will recommend the best solutions for any issues we identify.
