The air inside your home might feel comfortable, but is it truly clean? In today’s well-sealed and energy-efficient houses, the air you breathe every day can be up to five times more polluted than the air outside. Contaminants like dust, pollen, pet dander, mold spores, and chemical vapors from cleaning products and furnishings get trapped, endlessly circulating through your living spaces. This can lead to a host of issues, from persistent allergies and asthma flare-ups to headaches and general fatigue.
For homeowners in Weston, MA, creating a healthy indoor environment is a top priority. You deserve a home that is a true sanctuary, free from invisible airborne threats. Lavallee Systems specializes in providing comprehensive indoor air quality (IAQ) solutions designed to purify, balance, and refresh the air your family breathes, transforming your home into a haven of health and comfort.
Many factors contribute to poor indoor air quality. Without proper filtration and ventilation, your home’s HVAC system can inadvertently spread microscopic particles that impact your well-being. Common culprits include:
Ignoring these issues means allowing your family to be constantly exposed to pollutants. At Lavallee Systems, our mission is to provide effective, integrated solutions that address these problems at the source.

We don’t believe in one-size-fits-all fixes. We assess your home’s unique environment and your family’s specific needs to recommend a tailored strategy. Our suite of advanced IAQ systems works in harmony with your existing heating and cooling equipment to deliver clean, healthy air to every room:
Standard furnace filters are designed to protect your HVAC equipment, not your lungs. They only trap the largest dust particles. A whole-home air purifier, installed directly into your ductwork, removes microscopic contaminants before they ever enter your living spaces. Lavallee Systems installs high-efficiency purification systems capable of capturing up to 99% of airborne particles, including pollen, mold spores, bacteria, and viruses — providing significant relief for allergy and asthma sufferers.
The moisture level in your home’s air is critical for both comfort and health. The dramatic seasonal shifts in Weston demand a solution that can manage both dry winter air and humid summer conditions:
Whole-Home Humidifiers: Cold New England winters strip moisture from the air, leading to dry skin, irritated sinuses, static shock, and even damage to hardwood floors and furniture. A whole-home humidifier integrates with your furnace to add the perfect amount of moisture, maintaining optimal humidity for comfort and health.
Whole-Home Dehumidifiers: Sticky, humid summers can make your home feel uncomfortable and create an environment where mold and dust mites thrive. A whole-home dehumidifier from Lavallee Systems works with your air conditioner to remove excess moisture, preventing mold growth, eliminating musty odors, and allowing you to feel more comfortable at a higher thermostat setting.
Modern homes in Weston are built to be airtight for energy efficiency. While this helps with energy savings, it can trap stale air inside. A Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) from Lavallee Systems continuously exhausts stale indoor air while bringing in an equal amount of fresh, filtered outdoor air. In the winter, heat is transferred from the outgoing air to the incoming fresh air, and in summer, the process reverses — ensuring fresh air circulation without wasting energy.
