How to Improve Indoor Air Quality in Your Home

Introduction

Indoor air quality (IAQ) plays a critical role in your health and overall comfort. Poor air quality can exacerbate allergies, asthma, and other respiratory issues, while clean air can promote a healthier home environment. Fortunately, there are many ways to improve the air you breathe inside your home, from simple DIY solutions to professional HVAC upgrades. Here’s how you can enhance indoor air quality and create a cleaner, healthier living space.

1. Keep Your Home Clean

Regular cleaning reduces the accumulation of dust, pet dander, mold, and other allergens that can circulate through the air.

  • Vacuum Frequently: Use a vacuum with a HEPA filter to trap small particles, and vacuum carpets, rugs, and upholstered furniture regularly.

  • Dust and Mop: Dust surfaces with a damp cloth and mop floors to remove fine particles.

  • Wash Bedding: Wash bed linens, curtains, and other fabrics that collect dust in hot water weekly.

2. Change HVAC Air Filters Regularly

Your HVAC system’s air filters trap dust, pollen, pet dander, and other particles, preventing them from circulating in your home. Over time, these filters can become clogged and less effective, reducing air quality.

  • Frequency: Check and replace air filters every 1-3 months or as recommended by your manufacturer.

  • Upgrade Filters: Consider using high-efficiency filters, such as HEPA or pleated filters, for improved air filtration.

3. Invest in a Whole-Home Air Purifier

A whole-home air purifier can significantly improve air quality by removing allergens, bacteria, viruses, and other pollutants from the air.

  • How It Works: These systems work alongside your HVAC system to filter air as it circulates through your home.

  • Types: Options include UV air purifiers, activated carbon filters, and ionizers.

4. Control Humidity Levels

High humidity can create a breeding ground for mold, mildew, and dust mites, which can worsen allergies and asthma symptoms.

  • Ideal Humidity: Maintain indoor humidity levels between 30-50%.

  • Use a Dehumidifier: Consider using a dehumidifier to reduce moisture levels, especially in humid climates.

  • Ventilate Bathrooms and Kitchens: Use exhaust fans to remove moisture from the air after showers and cooking.

5. Improve Ventilation

Proper ventilation can help reduce indoor air pollutants by bringing in fresh outdoor air and reducing the concentration of contaminants.

  • Open Windows: When weather permits, open windows and doors to allow fresh air to circulate.

  • Use Exhaust Fans: Run exhaust fans in kitchens and bathrooms to expel moisture, smoke, and odors.

  • Energy Recovery Ventilators (ERVs): ERVs exchange stale indoor air with fresh outdoor air while maintaining energy efficiency.

6. Keep Ducts Clean

Dust, allergens, and mold can accumulate in your ductwork over time, affecting air quality and HVAC efficiency.

  • Schedule Regular Cleaning: Have your ducts inspected and cleaned by a professional if you suspect dust buildup or mold.

  • Check for Leaks: Ensure ducts are sealed properly to prevent contaminants from entering and circulating through your home.

7. Control Allergens with HEPA Filters

High-Efficiency Particulate Air (HEPA) filters are designed to trap 99.97% of particles as small as 0.3 microns, including dust, pollen, and pet dander.

  • Portable HEPA Air Purifiers: Use portable HEPA purifiers in high-traffic areas like bedrooms and living rooms.

  • Vacuum with a HEPA Filter: As mentioned earlier, using a vacuum with a HEPA filter further reduces allergens.

8. Minimize Indoor Pollutants

Reducing sources of indoor pollution can significantly improve air quality.

  • Avoid Smoking Indoors: Cigarette smoke contains harmful chemicals that can linger in the air and on surfaces.

  • Use Low-VOC Products: Choose paints, cleaning supplies, and building materials labeled as low in volatile organic compounds (VOCs).

  • Limit Use of Air Fresheners: Synthetic air fresheners can release harmful chemicals. Consider natural alternatives like essential oils.

9. Maintain Your HVAC System

Regular maintenance ensures that your HVAC system runs efficiently and effectively, contributing to better indoor air quality.

  • Schedule Annual Inspections: Have a professional HVAC technician inspect and maintain your system yearly.

  • Clean Coils and Components: Dirty coils and components can reduce airflow and contribute to poor air quality.

10. Test for Radon

Radon is a naturally occurring radioactive gas that can enter your home through cracks in the foundation. It’s odorless and invisible but can pose serious health risks.

  • Test Your Home: Use a radon testing kit or hire a professional to test for radon levels.

  • Mitigation Systems: If radon levels are high, a radon mitigation system can help reduce exposure.

11. Eliminate Mold and Mildew

Mold and mildew can contribute to poor indoor air quality and cause respiratory issues.

  • Fix Leaks Promptly: Address water leaks in roofs, walls, or pipes to prevent moisture buildup.

  • Clean with Mold-Resistant Products: Use mold-resistant paint and cleaning solutions in areas prone to moisture.

  • Remove Mold Safely: If mold is present, clean it with proper safety precautions, or call a professional for extensive infestations.

12. Add Indoor Plants

Certain indoor plants can help purify the air by absorbing toxins and releasing oxygen. However, be cautious as plants can also collect dust and contribute to indoor humidity.

  • Best Plants: Consider spider plants, peace lilies, and snake plants, which are known for their air-purifying properties.

  • Maintenance: Keep plant soil clean to prevent mold growth.

  • Why is water leaking from my indoor AC unit?
    Water leaks usually mean your drain line is clogged. In Fort Myers, algae builds up quickly due to humidity. We clear clogs and install float switches or access panels to prevent water damage in the future.
  • What should I check if my AC stops working?
    Start by checking your thermostat settings, breaker panel, and drain line. If everything looks normal and your AC still won’t turn on, call Big Air AC — we specialize in fast, reliable AC repair in Fort Myers.
  • Why does my AC blow warm air during the afternoon?
    This can happen when your AC is low on refrigerant, overheating, or undersized for your home. Fort Myers heat puts extreme stress on systems. We’ll diagnose the issue and recommend the best solution.
  • Why is my AC running but not cooling my house in Fort Myers?
    If your air conditioner is running but not cooling, it could be low on refrigerant, have a dirty coil, or a clogged drain line. These are common issues in Fort Myers due to heat, humidity, and algae buildup. We offer fast diagnostics to get your system cooling again.
  • What’s a normal AC temperature split in Fort Myers?
    A healthy system should have a temperature split (difference between return and supply air) of 18–22°F. If your TD is low, it could mean poor airflow, low refrigerant, or a dirty coil. We measure this on every call.
  • Can high humidity cause my AC to stop cooling?
    Yes. High humidity lowers your system’s ability to cool and dehumidify effectively. We measure the temperature differential (TD) and humidity levels at each call to catch this early.
  • Why does my AC blow warm air in the afternoon?
    If your AC works in the morning but blows warm later, it may be overheating, low on charge, or undersized for your home. Fort Myers afternoon heat puts massive strain on systems, especially older or improperly installed units.
  • Why is my AC running but not cooling the house?
    This is one of the most common issues in Fort Myers. It could be: Low refrigerant A dirty evaporator coil A clogged drain line tripping the float switch A failing capacitor or compressor We run full diagnostics and show you real-time readings so you know exactly what’s wrong.
  • Does the salt air near the coast wear out AC systems faster?
    Yes. Homes near the water often see corrosion on condenser coils and electrical components. Coastal homes benefit from protective coatings, routine rinsing, and more frequent inspections.
  • How long should an AC last in Fort Myers?
    Due to Florida’s heat, humidity, and salt in the air, most AC systems in Fort Myers last 10–15 years with regular maintenance. Without service, lifespan drops quickly. We help homeowners extend the life of their system with professional tune-ups and cleanings.
  • What can I do to make my AC last longer in Southwest Florida?
    The key is preventative maintenance. Clean filters, annual coil cleanings, and refrigerant checks reduce wear and tear. We also recommend installing surge protectors to protect electronics from Florida’s frequent lightning strikes.
  • What kind of warranty comes with a new AC installation?
    Every system we install includes a 1-year labor warranty and a 10-year parts warranty backed by the manufacturer. That means if anything goes wrong, you're covered — both for peace of mind and long-term protection. We handle the warranty registration for you, so you don’t have to lift a finger.
  • Do you offer financing or rebates for new HVAC systems?
    Yes! We offer affordable financing and can help you take advantage of utility rebates or manufacturer incentives when you upgrade to a high-efficiency AC system in Fort Myers.
  • Is it better to repair or replace my AC system?
    If your system is just old, but working fine, we would say just let it ride. If it needs frequent repairs, or struggles to keep up in the Fort Myers heat, replacement is often the smarter long-term move. We’ll walk you through your options and help you compare the cost of repairs vs. upgrading to a more efficient system.
