Understanding Indoor Air Quality and Why It Matters

Most people spend approximately 90% of their time indoors, yet the air inside our homes can be two to five times more polluted than outdoor air, according to the Environmental Protection Agency. At R. H. Witt Heating & Sheet Metal, we take indoor air quality seriously because it directly impacts your health, comfort, and overall well-being. As a family-owned and operated business located in Glenview, IL, founded by Richard H. Witt Jr. in 1966, we have spent decades helping homeowners throughout North Shore and Northwest Suburbs breathe cleaner, healthier air. Our approach goes beyond simply installing equipment. We specialize in designing comfort solutions that address not only your HVAC system but also analyze whether there are potential problems with the building envelope that could impact your comfort or indoor air quality.

Poor indoor air quality contributes to allergies, asthma flare-ups, respiratory infections, headaches, and fatigue. Contaminants such as dust mites, pet dander, mold spores, volatile organic compounds, and even carbon monoxide can circulate through your ductwork if left unchecked. Children, elderly individuals, and those with compromised immune systems are especially vulnerable to these airborne pollutants. Understanding the sources and solutions for indoor air contamination is the first step toward creating a healthier home environment.

Our Comprehensive Indoor Air Quality Assessment

We use state-of-the-art computerized diagnostic equipment to identify comfort issues, unhealthy air conditions, and high utility bill problems. Our assessment process begins with a thorough evaluation of your existing HVAC system, ductwork integrity, ventilation rates, and humidity levels. We measure airborne particulate counts and check for carbon monoxide and other harmful gases that may be present in your living spaces. This diagnostic approach allows us to pinpoint exact problem areas rather than guessing at solutions.

Beyond the mechanical systems, we examine the building envelope itself. Gaps around windows, insufficient insulation, and air leaks in the attic or crawl space can introduce outdoor pollutants while also allowing conditioned air to escape. Homes in Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL face unique seasonal challenges, from frigid winter air that dries out interiors to humid summer conditions that encourage mold growth. Our technicians are trained to account for these regional factors when recommending solutions tailored to your specific situation.

Solutions We Provide for Healthier Air

Once we complete our assessment, we develop a customized plan that may include one or more of the following indoor air quality solutions:

  • High-efficiency air filtration systems that capture particles as small as 0.3 microns, including bacteria, pollen, and smoke particles that standard filters miss
  • Whole-home humidifiers and dehumidifiers that maintain optimal humidity levels between 30% and 50%, reducing mold growth while preventing the dry air that leads to cracked skin and respiratory irritation
  • UV germicidal lamps are installed within the ductwork to neutralize bacteria, viruses, and mold spores as air passes through your HVAC system
  • Energy recovery ventilators that bring fresh outdoor air into your home while recovering energy from exhaust air to maintain efficiency
  • Duct sealing and cleaning services that eliminate accumulated dust, debris, and potential microbial growth inside your air distribution system

As a Carrier Distinguished Dealer, we have access to advanced product lines engineered for superior air quality performance. Every installation comes with our lifetime warranty on workmanship, and we back our services with a 100% satisfaction guarantee. Our customer satisfaction rating of 99% reflects the commitment our experienced management team and involved ownership bring to every project.

The Connection Between HVAC Performance and Air Quality

Your heating and cooling system is the lungs of your home. When it operates efficiently, it filters, circulates, and conditions air effectively. When it struggles due to aging components, dirty coils, or improperly sized ductwork, air quality suffers dramatically. A system that short-cycles or runs continuously cannot properly dehumidify or filter air, creating conditions where pollutants accumulate. As a full-service heating and air conditioning contractor serving homeowners in Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL, we ensure your entire system works in harmony to deliver both comfort and clean air.

Our technicians are always respectful of your home and make sure they leave your property as clean as when they arrived. We also provide 24/7 emergency service because air quality emergencies such as carbon monoxide detection or complete system failures do not follow business hours. Ongoing safety training and safety programs ensure both employee and customer safety during every service call.

Taking the Next Step Toward Better Air

Whether you are noticing increased allergy symptoms, musty odors, or excessive dust on surfaces, these are signals that your indoor environment needs attention. Contact R. H.
