Indoor Air Quality 101: Protecting Your Family at Home

The air inside your home is invisible, but it’s one of the biggest factors in your family’s health and happiness. If you’ve ever noticed a lingering smell, felt stuffy or sneezy indoors, or worried about allergies, you’re not alone. At Platts Heating & Air, we work with families every day who want to breathe easier and live better.

Indoor air quality (IAQ) isn’t just a comfort issue. It can impact sleep, trigger asthma, and even drive up your energy bills. Let’s break down the biggest threats, how to spot them, and what you can do—right now—to make your home safer.

The Most Common Indoor Air Quality Threats 🏠

Dust: Not Just a Nuisance

Dust is like glitter—it gets everywhere, hides in corners, and is almost impossible to get rid of completely. But dust isn’t just dirt. It’s a mix of dead skin, pet dander, pollen, tiny fabric fibers, and even dust mites. Breathing it in can irritate your lungs, especially for kids or anyone with asthma.

Where does dust come from?

• Carpets and rugs
• Bedding and furniture
• Heating and cooling vents
• Shoes tracking in dirt

Regular vacuuming helps, but if dust keeps coming back fast, it’s time to check your HVAC filters and ductwork.

Volatile Organic Compounds (VOCs): The Invisible Invader

VOCs are gases released by everyday items—like paint, cleaning sprays, air fresheners, and even new furniture. They can make your home smell “chemical” and, over time, can lead to headaches or other health issues.

Common sources:

• Freshly painted rooms
• New carpets or flooring
• Scented candles and air fresheners
• Household cleaners

The EPA warns that VOCs build up fast in closed spaces. Good airflow and choosing low-VOC products help keep levels down.

Humidity: Too High or Too Low

Humidity is the Goldilocks of home comfort—not too high, not too low. If air is damp, mold and dust mites thrive. Too dry? You’ll notice dry skin, irritated sinuses, and static shocks.

Warning signs:

• Condensation on windows (too humid)

Is the air inside your home truly safe to breathe? Most of us never think twice about indoor air quality—until a family member starts sneezing, coughing, or feeling groggy for no reason. At Platts Heating & Air, we see firsthand how the air you can’t see can affect the people you love.

Protecting your family means understanding what’s floating around indoors, how it gets there, and what you can do to improve it. Indoor air quality (IAQ) shapes your health, comfort, and even your energy bills. Let’s break it down together.

The Most Common Indoor Air Quality Threats 🛑

Dust: More Than Just a Chore

Dust is a silent traveler. It settles on your shelves, sneaks into air vents, and clings to every surface. But it’s more than an annoyance—it’s made up of pollen, skin flakes, pet dander, fabric fibers, and even bits of insects. If you find yourself dusting nonstop, your home’s air circulation or filtration might need attention.

• Why it matters: Dust can trigger allergies, worsen asthma, and clog HVAC systems.
• Where it hides: Carpets, bedding, vents, and behind furniture.

VOCs: The Unseen Chemicals

Volatile Organic Compounds (VOCs) are chemicals released as gases from common household products. Think of that “new paint” smell or fresh furniture scent. While some VOCs are harmless, others (like formaldehyde or benzene) can irritate your lungs and eyes or cause headaches.

• Where they come from: Paints, cleaning sprays, building materials, air fresheners.
• Why worry? High VOC levels can impact indoor air for months after renovations or deep cleans.

Humidity: The Balancing Act

Too much moisture feels sticky and breeds mold. Too little, and your skin dries out and your nose gets stuffy. The ideal indoor humidity sits between 30–50%, according to the EPA.

• High humidity: Can boost mold, dust mites, and bacteria growth.
• Low humidity: Triggers dry skin, static shocks, and breathing discomfort.

Allergens: Invisible Trouble

Pollen, pet dander, and mold spores are masters of disguise. They sneak through open windows, ride in on shoes, or drift from attic spaces. For allergy sufferers, these invisible intruders can make home life miserable.

• Signs of trouble: Sneezing, itchy eyes, frequent coughing, or unexplained fatigue.

Quick Safety Checklist: Is Your Home’s Air at Risk? ✅

• Do you notice lingering odors or musty smells?
• Are allergy symptoms worse at home than outside?
• Is there visible dust buildup on vents or furniture?
• Do you see condensation on windows or walls?
• Has it been over a year since your last HVAC filter change or duct cleaning?
• Are there pets, smokers, or recent renovations in your home?

If you answered “yes” to two or more, it’s time to take a closer look at your indoor air.

How to Test Indoor Air Quality: DIY vs. Professional

DIY Steps You Can Take

• Monitor humidity: Use an inexpensive digital hygrometer to check moisture levels.
• Check filters: Hold HVAC filters up to the light—if you can’t see through, it’s time to replace.
• Look for mold: Check around windows, bathrooms, and under sinks for spots or odors.
• Note symptoms: Keep a diary of allergy or asthma flare-ups and where they happen most.

When to Call a Pro

Some problems hide deep in your ducts or behind walls—places only trained eyes (and tools) can reach. If you suspect mold, have unexplained health issues, or want a thorough indoor air evaluation, call a certified HVAC technician. Emergency hvac services are available 24/7 for urgent issues.

What Pros Do On Arrival: The Platts Approach

When Platts Heating & Air comes to your home, we bring more than a toolbox. We use advanced testing equipment—like laser particle counters and VOC sensors—to identify hidden threats. Here’s what to expect:

• Visual inspection of your HVAC system, ductwork, and vents
• Air sampling and particle count analysis
• Humidity and temperature checks
• Filter and equipment review
• Clear, easy-to-understand explanations of your home’s air quality

Our technicians hold certifications in IAQ testing and follow EPA and ASHRAE guidelines for safety and accuracy.

Solutions: Clean, Fresh Air—Room by Room

High-Efficiency Filtration

A good filter is your first line of defense—like a catcher’s mitt for dust, pollen, and dander. Upgrading to HEPA or MERV 13 filters captures more particles and keeps your air cleaner.

• Change filters every 1–3 months (more often with pets or allergies)
• Ask about whole-home filtration for even greater protection

Air Scrubbers and Purifiers

Air scrubbers use UV light or special filters to “scrub” the air of bacteria, viruses, and VOCs. These systems are especially helpful for families with allergies, asthma, or chemical sensitivities.

• Install in your HVAC system for whole-home coverage
• Portable units available for bedrooms or nurseries

Humidifiers and Dehumidifiers

Balance is key. Whole-house humidifiers add moisture during dry winter months. Dehumidifiers pull excess water from the air in basements, bathrooms, or muggy climates.

• Maintain 30–50% indoor humidity year-round
• Prevent mold, static shock, and sinus discomfort

Duct Cleaning

Think of your ducts like lungs for your home. Over time, they can collect dust, mold, and debris. Professional duct cleaning can remove years of buildup and improve airflow.

• Recommended every 3–5 years, or after renovations or wildfires
• Reduces allergy symptoms and HVAC strain

Regular HVAC Maintenance

A well-maintained system does more than heat or cool—it helps filter and circulate fresher air. Schedule seasonal tune-ups with an emergency hvac provider like Platts Heating & Air to keep everything running smoothly.

Local & Seasonal Considerations

Your region and the season shape your IAQ needs. Pollen counts spike in spring and fall. Winters bring dry air and more time indoors. Summer storms or wildfires add challenges. Platts Heating & Air has experience addressing these seasonal shifts and can recommend the right mix of filtration, humidity control, and maintenance—wherever you live.

Clean air is a foundation for a healthy, happy family. Don’t wait for a sneeze or stuffy nose to take action.
