The quality of the air you breathe inside your home has a direct and significant impact on your family's health, comfort, and overall well-being. While we often think about outdoor pollution, the U.S. Environmental Protection Agency (EPA) reports that indoor air can be two to five times more polluted than the air outside. In Wellesley, MA, homes can trap a variety of contaminants, from seasonal allergens like pollen and mold spores to dust, pet dander, and chemical off-gassing from furniture and cleaning products. These invisible particles circulate through your HVAC system, potentially triggering allergies, asthma, and other respiratory issues.
At Lavallee Systems, we provide comprehensive indoor air quality (IAQ) solutions designed to address the specific challenges faced by Wellesley homeowners. We don’t just treat symptoms—we create a healthier indoor environment by identifying the root cause of air quality issues and implementing targeted, effective systems. Our goal is to ensure that every breath you take in your home is fresh, clean, and pure.
We offer a suite of advanced services and systems, each designed to combat different types of airborne pollutants and create a perfectly balanced indoor atmosphere. Our experts at Lavallee Systems will help you determine the right combination of solutions for your home’s unique needs.

Everyday life introduces a host of microscopic pollutants into your air. Dust mites, pet dander, viruses, bacteria, and volatile organic compounds (VOCs) can circulate freely, diminishing your air quality. Our whole-home air purification systems integrate directly with your existing HVAC system to capture and eliminate these threats before they reach your living spaces. Using technologies like high-efficiency HEPA filters, which capture 99.97% of airborne particles, and UV germicidal lamps that neutralize viruses and bacteria, Lavallee Systems can dramatically reduce contaminants in your home, providing powerful relief for allergy and asthma sufferers.
The long, dry winters in Wellesley can wreak havoc on your home’s indoor environment. Insufficient humidity leads to dry skin, irritated sinuses, scratchy throats, and an increased susceptibility to colds and infections. It can also damage your home's wood floors, furniture, and structural elements. A whole-home humidifier from Lavallee Systems works in tandem with your furnace to add the perfect amount of moisture to the air. This balanced humidity not only improves comfort and health but also helps your home feel warmer at lower temperatures—potentially reducing your heating costs.
Modern homes in Wellesley are built to be airtight for energy efficiency, but this can lead to a buildup of stale air, odors, and pollutants. Without proper ventilation, carbon dioxide, moisture, and VOCs become trapped inside. Lavallee Systems installs advanced ventilation systems like Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) to solve this issue. These systems continuously exchange stale indoor air with fresh, filtered outdoor air—while recovering a significant portion of the heating or cooling energy—keeping your home both fresh and energy-efficient.
Your ductwork is the respiratory system of your home, but over time, it can accumulate layers of dust, debris, mold, and other allergens. Every time your HVAC system runs, it can push these contaminants into your living spaces. The professional duct cleaning service from Lavallee Systems uses powerful, specialized equipment to thoroughly scrub and sanitize your entire duct system. This process removes years of buildup, improves airflow, boosts HVAC efficiency, and eliminates a major source of indoor air pollution—resulting in an immediate and noticeable improvement in the air you breathe.
