What We Offer

Our Indoor Air Quality Services in Marlborough, MA

A full-service approach to indoor air quality — from testing and diagnosis to installation and ongoing maintenance.

IAQ Testing & Analysis

Comprehensive air quality testing measures levels of VOCs, CO₂, particulate matter, humidity, and more — giving you a clear picture of your home's air.

Air Filtration Systems

Installation and maintenance of whole-home air filtration systems, including HEPA-rated media filters and electronic air cleaners that capture particles down to 0.3 microns.

UV Air Purifiers

UV germicidal irradiation systems installed in your HVAC system neutralise bacteria, viruses, mould spores, and other biological contaminants in the air stream.

Humidifiers & Dehumidifiers

Whole-home humidification and dehumidification solutions that maintain optimal indoor humidity (40–50%) — reducing respiratory irritation, static, and mould risk.

Ventilation Solutions

ERV and HRV systems that introduce fresh outdoor air while recovering heating or cooling energy — balancing air quality with efficiency.

Customised IAQ Plans

After IAQ testing, we develop a tailored plan recommending exactly the right combination of systems for your specific home and household health needs.

Common Questions

Indoor Air Quality FAQs — Marlborough, MA

Indoor air quality refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of occupants. The EPA estimates that indoor air can be 2–5 times more polluted than outdoor air — containing VOCs, particulate matter, allergens, mould spores, bacteria, and other contaminants. Poor IAQ is linked to respiratory conditions, allergies, headaches, and reduced cognitive performance.
Common signs include persistent allergy or asthma symptoms that are worse indoors, unexplained headaches or fatigue, musty or unusual odours, visible mould growth, excessive dust buildup, or high humidity and condensation. The only way to accurately measure IAQ is with professional testing.
Our comprehensive IAQ assessment measures VOC levels, CO₂ concentrations, particulate matter, humidity, temperature, and ventilation rates throughout your home using calibrated professional instruments. We provide a written report of all findings and clear recommendations.
We install whole-home air filtration systems, UV germicidal irradiation systems, whole-home humidifiers and dehumidifiers, energy recovery ventilators (ERV), and heat recovery ventilators (HRV). We also service and maintain existing IAQ systems of all brands.
Depending on the system type, some IAQ installations may qualify for utility rebates or energy efficiency incentives. We’ll identify any applicable incentives during your consultation.
Most residential IAQ installations are completed in a single day — often less. More complex whole-home systems, such as ERV/HRV installations requiring ductwork modifications, may take 1–2 days.
