When summer arrives in East Tennessee, homeowners often focus on keeping their homes cool and comfortable. However, while your HVAC system works to regulate temperature, it also plays a major role in managing the air you breathe. During the summer, when windows are shut tight and AC units are running continuously, indoor air quality (IAQ) can suffer. Poor IAQ can lead to allergies, respiratory issues, and a generally unhealthy living environment.

At Advanced Heat, AC & Plumbing, we help homeowners across East Tennessee improve their indoor air quality through professional HVAC services, upgrades, and expert advice. In this article, we’ll explore how your HVAC system can help you create cleaner, healthier air throughout the summer.

Why Indoor Air Quality Matters in Summer

In the warmer months, people spend more time indoors with closed windows and sealed homes to keep the cool air inside. Unfortunately, this traps pollutants like dust, pet dander, mold spores, and volatile organic compounds (VOCs) inside your living space. Without proper ventilation and filtration, these pollutants continuously circulate, impacting your health and comfort.

Poor indoor air quality can lead to:

  • Allergies and asthma flare-ups
  • Eye, nose, and throat irritation
  • Fatigue and headaches
  • Long-term respiratory issues

That’s why improving IAQ should be part of your summer home maintenance plan.

Key HVAC Strategies to Improve Indoor Air Quality

Your HVAC system isn’t just a cooling solution—it’s also your first line of defense against indoor air pollution. Let’s break down the most effective ways to use your HVAC system to boost IAQ this summer.

1. Regular HVAC Maintenance Is Essential

One of the most impactful ways to improve air quality is to schedule regular HVAC maintenance. Dirty coils, clogged filters, and poorly maintained equipment not only reduce cooling efficiency but also contribute to poor air circulation and the spread of pollutants.

During a professional tune-up, your technician will:

  • Clean or replace air filters
  • Inspect and clean coils
  • Check ductwork for dust buildup
  • Ensure the condensate drain is clear to prevent mold growth

Regular maintenance keeps your system running efficiently and minimizes the circulation of dust and contaminants.

2. Upgrade to High-Efficiency Air Filters

Standard air filters trap large particles like dust and debris but often miss smaller allergens, mold spores, and bacteria. To significantly improve indoor air quality, consider upgrading to high-efficiency filters with a higher Minimum Efficiency Reporting Value (MERV) rating.

Filters rated MERV 11 to 13 are ideal for most homes and can capture:

  • Pollen
  • Pet dander
  • Mold spores
  • Fine dust
  • Smoke particles

Be sure to check your HVAC system’s compatibility with high-MERV filters to avoid airflow restrictions. For assistance, you can always consult Advanced Heat, AC & Plumbing for expert recommendations.

3. Install a Whole-Home Air Purification System

While air filters handle many pollutants, a whole-home air purifier can provide an additional layer of protection. These systems work alongside your HVAC to neutralize airborne particles, odors, bacteria, and viruses.

Some popular options include:

  • HEPA filtration systems
  • UV light purifiers that kill bacteria and mold
  • Electronic air cleaners that trap ultra-fine particles

4. Control Humidity Levels

East Tennessee summers bring high humidity, which can make your home feel warmer and encourage mold and mildew growth. Mold spores not only damage your home but also trigger allergies and respiratory problems.

To maintain healthy indoor air quality:

  • Aim for indoor humidity levels between 30% and 50%.
  • Install a whole-home dehumidifier to regulate moisture.
  • Ensure your air conditioner’s condensate drain is clear to prevent standing water.

At Advanced Heat, AC & Plumbing, we offer HVAC system upgrades, including humidity control solutions that can be integrated seamlessly with your existing equipment.

5. Clean and Seal Ductwork

Over time, your home’s ductwork can accumulate dust, pet hair, mold, and even pests. When the air conditioner runs, it can circulate these contaminants throughout your home.

Benefits of professional duct cleaning include:

  • Improved airflow
  • Reduced dust buildup in living spaces
  • Fewer allergens circulating in the air

Additionally, leaky ducts can pull in unfiltered air from attics, crawl spaces, and basements, which may be filled with pollutants. Sealing your ductwork improves efficiency and prevents unwanted contaminants from entering your system.

If you notice signs of excessive dust, musty odors, or weak airflow, contact Advanced Heat, AC & Plumbing to schedule a duct inspection.

6. Use Ventilation Wisely

Proper ventilation is crucial for bringing fresh air into your home and pushing out stale, polluted air. However, relying solely on open windows isn’t always practical during East Tennessee’s hot summers.

Consider:

  • Installing energy recovery ventilators (ERVs) that exchange stale indoor air for fresh outdoor air without sacrificing cooling efficiency.
  • Running bathroom and kitchen exhaust fans regularly to remove moisture and odors.

Balanced ventilation supports better air circulation without overburdening your HVAC system.

7. Smart Thermostat Control for Air Quality

A smart thermostat not only improves cooling efficiency but can also help you manage air quality by:

  • Scheduling air circulation to prevent stagnation
  • Automating humidity control
  • Providing air quality alerts if your system includes compatible sensors

Smart thermostats allow you to monitor and adjust your indoor environment from your phone, giving you more control over both comfort and air quality.

Common Indoor Pollutants to Watch For

Understanding what’s in your indoor air can help you choose the right HVAC upgrades and maintenance strategies. Common summer pollutants include:

  • Pollen: Easily enters homes on clothing and pets.
  • Pet Dander: A frequent allergen that can linger in air ducts.
  • Dust Mites: Thrive in warm, humid environments.
  • Mold Spores: Flourish in high-humidity areas.
  • VOCs: Emitted by cleaning products, paint, and furniture.

Combatting these pollutants requires a combination of filtration, humidity control, and ventilation.
