Signs Your Home Has Poor Indoor Air Quality
Is your home healthy? It might not be as healthy as you think. Pollution can be two to five times more concentrated indoors compared to outdoors, as stated by the U.S. Environmental Protection Agency.
Indoor air pollutants moving with your home’s air will sometimes result in headaches and allergy symptoms. And mold and mildew can cause a host of health concerns.

Health Problems
While many of these symptoms can be a consequence of other issues, they can also be evidence your home is dealing with indoor air quality (IAQ) problems. This is particularly true if you feel normal again while you’re out of the house.
- Dry eyes, nose, throat or skin
- Headaches and sinus irritation
- Fatigue
- Allergies or asthma symptoms that are more intense than usual
- Coughing and sneezing
- Dizziness or nausea
Environmental Problems
A well-worn heating and cooling system can be a contributing factor in indoor air quality problems, particularly if it’s unable to filter air, regulate humidity or keep temperatures consistent.
Here are a few other signs you may need to improve your indoor air:
- Excess static or mold growth
- High quantities of dust
- Stuffy or musty odors

How Can I Prevent Indoor Air Quality Problems?

Combating indoor air quality problems is comparatively easy with the following 10 simple tips:
- Plan an indoor air quality audit with B & G HVAC. We’ll evaluate areas that impact air quality, such as humidity, carbon monoxide and volatile organic compounds (VOCs). Then we’ll go over whatever issues we find and how you can improve them.
- Clean consistently to reduce dust mites, which can aggravate allergies and asthma.
- Keep your home free of secondhand smoke.
- Use a whole-home filtration system to eliminate odors, instead of masking them with air fresheners or strong candles. The pollutants include chemicals that can cause headaches or irritate respiratory illness.
- Air out gas-burning appliances, such as stoves and water heaters, up and out.
- Keep your home’s humidity levels in check with a humidifier or dehumidifier, based on your needs. Adjust humidity under 50% to restrict mold and mildew spores.
- Check your home for radon. Long-term exposure to this invisible radioactive gas is the leading cause of lung cancer for nonsmokers, as stated by the EPA. You can buy a radon test kit online or contact your state radon program for information on discounted or free kits.
- Implement a ventilation system to exchange contaminated indoor air with fresh outdoor air.
- Choose natural cleaning and painting materials that are low in or free of VOCs. Elevated levels of VOCs can aggravate symptoms for family members with respiratory illnesses.
- Place carbon monoxide detectors right outside bedrooms.
