The average person spends 90% of their time indoors. And if you're one of millions of remote workers, that number may be even higher. What’s concerning isn't the time you spend in your home; it’s the poor air quality issues you may not even know you’re living with.

From microscopic dust mites and pet dander to mold, bacteria, and even viruses, poor air quality is a serious health and safety concern. Your HVAC system is your first line of defense. And with proper maintenance and upgrades, your system can help reduce air pollution in your home. Here’s how.

Common Home Air Quality Issues

Most indoor air is rife with invisible allergens that can put a damper on your health and comfort. Learning how HVAC systems reduce air pollution begins with understanding these common contaminants:

  • Dust mites are microscopic invaders that thrive in dust—particularly carpeting and upholstery. These unwelcome creatures can trigger asthma attacks and allergic reactions.
  • Pet dander doesn’t just stick to clothing and furniture. It’s an allergen that can circulate inside your HVAC system and spread throughout your home.
  • Mold can cause headaches, respiratory infections and more deadly health issues. Without proper HVAC system maintenance, mold can grow inside ductwork and spread throughout the home.
  • Pollen can sneak into your home and circulate through your HVAC system, triggering allergy symptoms year-round instead of just during peak seasons.

It's worth noting that this is not a comprehensive list. Other contaminants, including bacteria, viruses, and even smoke particles, can compromise indoor air quality.

The good news? Most modern HVAC systems are designed to combat these threats—you just need to keep up with maintenance and consider upgrading air quality features.

How HVAC Systems Reduce Allergens in the Home

Modern HVAC control systems are surprisingly good at fighting allergens. But to get the most out of your system, we recommend:

Keeping Up With Maintenance

Many homeowners put their HVAC systems on autopilot. However, to help you stay healthy and comfortable, your furnace and air conditioner need regular maintenance. Over time, filters accumulate pollutants, which not only compromises air quality but forces your system to work harder.

Multi-Stage Filtration Upgrades

Understanding how HVAC systems reduce air pollution starts with a quick lesson on filtration.

Most filters will capture large dust, lint, and pollen particles. However, many do not filter out smaller particles like mold spores, pet dander, and dust mites. Our air quality experts will help you select a filter that not only only improves air quality but also reduces energy consumption.

Humidity Control

When humidity is too high, your home can quickly become a breeding ground for bacteria. Too low, and it can irritate your respiratory system. Luckily, we offer a full line of HVAC control systems, including humidifiers and dehumidifiers, to balance your air quality and fight against pollutants.

Air Purification

While ongoing maintenance, a new filter, and humidity control will certainly improve air quality, sometimes homeowners need comprehensive protection. Our air purification systems integrate with your existing ductwork to filter out contaminants at a molecular level.

Duct Cleaning

Over time, your air ducts can become a breeding ground for dust, dander, mold, and mildew. Our duct cleaning will improve air quality, eliminate odors, protect your HVAC system, and lighten your cleaning load.
