The Impact of Poor Indoor Air on Your Health and Comfort

Indoor air quality is frequently a hidden issue that can have a notable impact on your health and comfort levels. The Environmental Protection Agency (EPA) states that indoor air may be up to five times more polluted than the air outside. Many homeowners and business owners unknowingly expose themselves to allergens, mold, bacteria, and airborne chemicals daily.

Common Indoor Air Contaminants Include:

  • Dust and Pet Dander: These are some of the most common household allergens, often found on furniture, carpets, and bedding. Dust mites thrive in dusty environments, while pet dander comes from the skin flakes and saliva of furry animals. Both can trigger sneezing, coughing, itchy eyes, and other respiratory issues, especially for those with allergies or asthma.
  • Mold Spores: Mold grows in warm, damp, and poorly ventilated areas such as bathrooms, basements, or near leaky windows. The spores released by mold can cause allergic reactions like a runny nose, itchy throat, or skin irritation. Prolonged exposure can result in more severe health problems, including respiratory infections or exacerbation of pre-existing conditions like asthma.  
  • Chemicals from Cleaning Products: Many commercial cleaning products are packed with harsh chemicals such as ammonia, bleach, and synthetic fragrances. These substances can irritate the skin, eyes, and respiratory system, especially when used in poorly ventilated areas. Extended exposure to these chemicals may also pose significant long-term health risks.
  • Volatile Organic Compounds (VOCs): VOCs are toxic chemicals that evaporate into the air from everyday items like paints, adhesives, furniture, and even air fresheners. Short-term exposure may result in symptoms like headaches, dizziness, and nausea, while prolonged exposure can lead to severe health complications, including liver, kidney, or central nervous system damage.  
  • Pollen and Outdoor Pollutants: Pollen, along with other outdoor pollutants like smog or vehicle emissions, can quickly enter your home through open windows, doors, or ventilation systems. Once inside, these particles can settle on surfaces and trigger allergic symptoms such as sneezing, congestion, or itchy eyes, particularly during peak allergy seasons.

Indicators of Poor Indoor Air Quality:

  • Persistent sneezing, coughing, or allergy symptoms indoors could signal the presence of allergens such as dust mites, mold, or pet dander.
  • Persistent musty or stale odors could be a sign of mold growth or poor ventilation within your home.  
  • Excessive dust accumulation on surfaces, furniture, or in the air indicates inadequate air filtration or cleaning.  
  • High or low indoor humidity levels, which can create uncomfortable living conditions and contribute to mold growth or dryness issues.  
  • Increased respiratory issues, headaches, or other health symptoms, potentially caused by poor air quality or exposure to harmful pollutants.

By addressing these air quality concerns, Hely Heating and Air Conditioning Co. helps protect your home or business from airborne threats, ensuring a healthier and more comfortable indoor environment.

Our Indoor Air Quality Services: Tailored to Your Needs

We provide a wide range of indoor air quality services designed to target common pollutants and create a healthier indoor environment. Our tailored solutions cater to residential and commercial properties alike, ensuring optimal air quality year-round.

Our Advanced Indoor Air Quality Solutions:

  • Air Cleaner: Using advanced technology, our air cleaners effectively remove dust, pollen, pet dander, and other common pollutants as small as 0.01 microns—18,000 times smaller than the head of a pin. Their efficiency is evaluated using the Minimum Efficiency Reporting Value (MERV) scale, where higher ratings indicate superior filtration performance. Designed to tackle even the finest particles, they are perfect for allergy sufferers and anyone looking to improve indoor air quality. Our cleaners range from MERV 10 to MERV 15 to fit various needs. For severe allergies, we also offer Whole House HEPA filtration systems for top-tier air purification.

  • Air Scrubber: This cutting-edge technology is designed to improve IAQ by using a combination of high-intensity UV light, activated carbon cells, and ozone. Together, these components work to remove and destroy harmful indoor air pollutants, ensuring a cleaner and healthier environment. Our air scrubbers are highly effective in eliminating mold spores, bacteria, volatile organic compounds (VOCs), and smoke particles. They not only reduce contaminants in the air but also help to minimize odors, making them an excellent solution for homes, offices, and other spaces where air quality is a priority.

  • Humidifiers & Dehumidifiers: Maintaining proper humidity levels is essential for a comfortable and healthy home. Humidifiers are designed to add moisture to the air, preventing issues caused by dryness, such as cracked skin, irritated eyes, and respiratory discomfort. They are particularly beneficial during colder months when indoor heating can lead to excessively dry air. On the other hand, dehumidifiers work to remove excess humidity, which can lead to dampness, musty odors, and the growth of mold and mildew. By reducing excess moisture, dehumidifiers also help protect your walls, ceilings, and wooden furniture from damage caused by humidity. Keeping humidity levels balanced enhances overall air quality, reduces allergens, and creates a healthier, cozier living environment for the entire household.

  • Ventilation Solutions: Proper ventilation is vital to maintaining a comfortable and healthy indoor environment by circulating fresh air and preventing stale or polluted air. Solutions like exhaust fans, air exchangers, and balanced ventilation systems remove odors, moisture, and harmful particles while replenishing oxygen. This improves air quality, controls humidity, reduces mold, and minimizes allergens. Good airflow enhances comfort, reduces pollutants, and creates a healthier space for homes, offices, and commercial buildings.  
  • Duct Cleaning & Sealing: Over time, air ducts collect dust, allergens, debris, and mold, which block airflow and reduce HVAC efficiency. Professional duct cleaning removes these contaminants, improving air quality and reducing health risks like allergies or respiratory issues. Sealing ducts eliminates energy-wasting leaks and ensures consistent heating or cooling. Clean, sealed ducts improve HVAC performance, lower energy costs, and extend system lifespan, ensuring comfort and efficiency year-round.

Our solutions are tailored to your needs, whether you're looking to combat seasonal allergies, improve your HVAC efficiency, or eliminate musty odors.
