Indoor Air Quality

Indoor air quality has always been central to occupant health, comfort, and productivity. Poorly managed HVAC systems can circulate pollutants, allergens, and airborne pathogens, putting both people and equipment at risk.

With GDI Ainsworth, you gain proven strategies and technologies that ensure safer, healthier indoor environments while maintaining energy efficiency and compliance.

Indoor Air Quality Calculator

Making informed decisions about healthy air shouldn’t be complicated. That’s why GDI Ainsworth developed the Healthy Ventilation Planner, a quick tool designed for facilities under 50,000 square feet. In just a few questions, you’ll get a tailored budget and clear performance benchmarks, including:

Give it a try! It will only take you a minute!

Air Quality Testing

Our advanced pathogen and particulate sensing provides visibility into what’s circulating in your facility. Regular air quality testing reduces blind spots and confirms whether your air quality strategies, like filtration, ventilation, purification, and occupancy management, are performing as intended.

Dynamic dashboards give you spatially mapped views of conditions across your building, so you can act quickly and confidently. Early alerts highlight when harmful particulates exceed healthy thresholds, and our experts build actionable response plans that help you maintain a safe, productive indoor environment.

Smart IAQ: A Four-Step Approach to Healthier Air

Our SmartIAQ program uses advanced technology to measure, monitor, and control HVAC performance, reducing airborne viruses, bacteria, and allergens.

As part of our Clean for Health program, we integrate with facility cleaning teams to deliver a complete, building-wide approach to healthier indoor environments.

Enhanced Filtration

We assess your HVAC system and upgrade to MERV-13 filtration wherever possible. Regular maintenance and timely replacements ensure filters perform as designed and capture harmful particulates effectively.

Dilution Ventilation
Bringing more outdoor air indoors improves occupant health and comfort. Our cloud-based BAS programs help your HVAC system to increase fresh air circulation and let you adjust ventilation modes in real time.
Air Purification & Surface Conditioning
Using ultraviolet lights (UVGI) within the HVAC system, we can sanitize the coil surface and purify indoor air.
Occupancy Management
Our smart technologies give you real-time visibility into how spaces are being used. These systems track occupancy levels, traffic patterns, and environmental conditions, helping you optimize ventilation, energy use, and space management.

Air Purification

GDI Ainsworth installs advanced purification systems within commercial HVAC units, removing mold, bacteria, and viruses directly from ductwork and coils. These solutions improve indoor air quality in facilities of all sizes, creating environments that support both well-being and operational performance.

Sanitizing Evaporator
We apply Evap-Fresh Spray, an EPA-registered antimicrobial odorless product, to remove and kill bacteria and restore HVAC unit sanitization.
High Efficiency Filters
Our team will upgrade existing HVAC air filters to a higher MERV (Minimum Efficiency Reporting Value) to decrease contaminants in air circulation.
Bipolar Ionization
We can install air purification devices to deliver ionized air molecules that can attach to airborne pollutants and remove 95% of them from breathable air.
UV Air Purifier
Installing a UV light air purifier in the air conditioning ductwork or an evaporator coil stops microbiological growth and destroys up to 85% of pathogens.
