Breathe Healthier, Cleaner Air in Your Maryland Heights Home
The air inside your Maryland Heights home can be significantly different from the air outside, and not always for the better. While you might see current air quality reports for the region, the air you breathe indoors can be up to five times more polluted than outdoor air. Dust, allergens, chemicals, and other microscopic particles can accumulate within your living spaces, impacting your health, comfort, and even the lifespan of your HVAC system. Addressing indoor air quality (IAQ) isn't just about comfort; it's about creating a healthier environment for you and your family.
At Hely Heating and Air Conditioning, we understand the unique challenges faced by homeowners in Maryland Heights when it comes to maintaining healthy indoor air. Our decades of experience serving the St. Louis and Jefferson Counties mean we're familiar with the local environment and the types of pollutants that commonly affect homes here. We specialize in identifying and implementing tailored indoor air quality solutions designed to create a cleaner, safer, and more comfortable living space for you.

Understanding Common Indoor Air Pollutants
Your home's air is a complex mix, and many things contribute to its quality. Common indoor air pollutants found in Maryland Heights homes can include:
- Dust and Particulates: Everyday dust contains skin flakes, pet dander, lint, and soil particles tracked in from outside. These microscopic particles are constant irritants.
- Pollen: While primarily an outdoor allergen, pollen easily finds its way indoors through open windows and doors, on clothing, and even carried in by your pets.
- Mold and Mildew: Excess moisture from humidity, leaks, or poor ventilation can lead to mold and mildew growth, releasing spores that trigger allergies and respiratory issues.
- Pet Dander: Tiny flakes of skin shed by cats, dogs, and other pets are a major allergen source.
- Volatile Organic Compounds (VOCs): Found in paints, cleaning supplies, furnishings, and building materials, VOCs off-gas into the air and can cause various health problems.
- Dust Mites: Microscopic creatures that thrive in dusty environments, feeding on skin flakes and leaving behind waste products that are potent allergens.
- Bacteria and Viruses: These pathogens can circulate through the air, contributing to the spread of illness.
These pollutants are often invisible to the naked eye but can have a noticeable impact on your daily life.

Signs Your Home's Air Quality Needs Attention
How can you tell if the air quality in your Maryland Heights home might be poor? Look for these common signs:
- Increased allergy symptoms, especially when indoors (sneezing, coughing, itchy eyes, runny nose).
- Worsening asthma or other respiratory conditions.
- Persistent cough or congestion unrelated to illness.
- Dry or irritated skin and eyes.
- Frequent headaches or fatigue when at home.
- Noticeable dust accumulation shortly after cleaning.
- Musty or stale odors.
- Visible mold or mildew growth.
- High humidity levels leading to condensation on windows or cold surfaces.
If you notice any of these indicators, it's a good idea to investigate the quality of your indoor air.
The Health Connection: Why Clean Air Matters
The pollutants in your home's air don't just cause discomfort; they can have significant long-term health effects. Exposure to poor indoor air quality is linked to:
- Exacerbated allergies and asthma symptoms.
- Development of respiratory infections.
- Increased risk of chronic respiratory diseases.
- Headaches, fatigue, and difficulty concentrating.
- Skin and eye irritation.
- Potential long-term health issues from prolonged exposure to certain chemicals.
Ensuring clean indoor air is an investment in the health and well-being of everyone living in your Maryland Heights home.
Our Comprehensive Indoor Air Quality Services
Hely Heating and Air Conditioning offers a range of proven solutions to address various indoor air quality issues in your Maryland Heights home. Our experienced technicians can help you identify the specific problems you're facing and recommend the most effective strategies. Our IAQ services include:
- Indoor Air Quality Assessment: The first step to solving an IAQ problem is understanding it. We can perform a thorough assessment to identify potential pollutants, sources, and areas of concern in your home's air. This helps us recommend targeted solutions rather than guesswork.
- Whole House Air Purifiers: These systems integrate with your existing HVAC system to filter and clean the air circulating throughout your entire home. Options include advanced media filters (much more effective than standard furnace filters), electronic air cleaners, and UV germicidal lights that kill airborne bacteria and viruses.
- Humidity Control Solutions: Both excessive humidity and air that is too dry can cause problems. High humidity encourages mold growth and attracts dust mites, while low humidity can cause dry skin, irritate nasal passages, and damage wood furnishings. We offer solutions like Whole House Humidifiers to add moisture in dry winter months and dehumidifiers to remove excess moisture during humid periods.
- Advanced Filtration: Upgrading your HVAC system's air filter is a simple yet effective way to improve air quality. We can advise on and install high-efficiency filters that capture a much larger percentage of airborne particles than standard filters.
- Ventilation Strategies: Proper ventilation exchanges stale indoor air with fresh outdoor air, diluting pollutants. We can assess your home's ventilation and recommend improvements or systems like energy recovery ventilators (ERVs) that bring in fresh air efficiently.
- Duct Cleaning: Over time, dust, debris, allergens, and even mold can accumulate in your HVAC ductwork. When your system runs, it can blow these contaminants into your living spaces. Professional duct cleaning removes this buildup, contributing to cleaner, healthier air.
How Our IAQ Solutions Work
Each IAQ solution targets specific types of pollutants:
- Filtration systems physically capture particles as air passes through them. Higher Minimum Efficiency Reporting Value (MERV) ratings indicate filters that capture smaller particles, including many allergens.
- Electronic air cleaners use an electrostatic charge to attract and trap particles.
- UV germicidal lights (often installed within ductwork or near the air handler coil) use ultraviolet light to neutralize or kill microorganisms like bacteria, viruses, and mold spores as they pass by.
- Humidifiers add moisture vapor to dry air, while dehumidifiers remove excess moisture.
- Ventilation systems introduce fresh, filtered outdoor air while exhausting stale indoor air.
Combining solutions often provides the most comprehensive approach to improving your home's air quality profile.
