Indoor Air Quality (IAQ) Solutions

Expertise, services and solutions to improve your building’s air quality and achieve a healthier, more viable space for those inside.


What is Indoor Air Quality?

Indoor air quality refers to the quality of air circulating in and around your building. While often invisible to the naked eye, there are many airborne pollutants and other health risks in the built environment. Understanding what’s in the air you breathe and taking measures to improve your indoor air quality can have a profound impact on the health of your building and those inside it.

How to Improve Indoor Air Quality

The most effective way to improve your indoor air quality is to implement personalized solutions that balance the well-being of your occupants with your business and energy goals. That’s why our process begins with an IAQ assessment to understand your operational challenges, evaluate your current air quality and provide recommendations for improving it. From there, your dedicated Trane expert will create a portfolio of solutions backed by ASHRAE® and REHVA® guidelines and designed to dilute, exhaust, contain and clean the air in your building. By aligning our building expertise with your business realities, we’re able to provide individualized strategies that help you make the right IAQ investment and add value to your building for years to come.

How do you Monitor Indoor Air Quality?

In order to effectively monitor indoor air quality, you need to be able to visualize your building data and make changes in real-time. Trane’s integrated monitoring and controls solutions make that possible. Complete with remote connectivity and up-to-the-second dashboard reporting, our app-based technology gives you 24/7 visibility into your air quality to make precise optimizations and share status updates with stakeholders from anywhere in the world. This allows you to monitor performance with confidence and take control of your investment.

What are the Benefits of Improving Indoor Air Quality?

Improving your indoor air quality is one of the most effective ways to address airborne health risks in your building. According to the Center for Disease Control, infectious germs are commonly spread through respiratory droplets1. That makes air quality a primary factor for human wellness. Not only that, clean, well-optimized air can boost productivity levels and potentially reduce your energy costs as well. While its impact on your facility ultimately depends on a variety of factors unique to your business, there are some common ways you stand to benefit from IAQ :

  • Mitigate airborne pollutants in your building
  • Protect the health and well-being of your occupants
  • Maintain comfortable humidity levels year-round
  • Reduce energy costs with improved air flow
  • Achieve a more energy-efficient and sustainable operation

Synexis® is a bio-defense firm behind a new and innovative technology that takes humidity (H2O) and Oxygen (O2) from the air and converts it into Dry Hydrogen Peroxide (DHP) to reduce the presence of unwanted microbes from the air and surfaces in your building. To help you maximize the impact of DHP on your building, Trane uses a unique 3-step process to confirm how DHP fits as part of your greater IAQ solution to optimize performance and identify the key metrics and targets to help manage goals. Learn more about how Trane can help you take advantage of DHP technology from Synexis.

Trane® Catalytic Air Cleaning System (TCACS)

The Trane® Catalytic Air Cleaning System is a powerful three-in-one application that eliminates organic contaminants from the outside air before they enter your building. When external airflow finds the TCACS, it passes through an innovative blend of filtration, UVGI and photocatalytic oxidation barriers designed to capture large contaminants like mold spores and pollen, then neutralize and decompose smaller microorganisms such as viruses, VOC’s and odors. The end result is clean, sterile air by the time it reaches your space. Click to learn more about TCACS today!

Filter Solutions

In accordance with the latest CDC and ASHRAE® guidance, Trane offers a broad portfolio of High-Efficiency filters including MERV 13 filters designed to capture many of the larger biological contaminants and particles in the air, such as mold spores and pollen. But not all HVAC units are big enough to install MERV filters, in which case you may require a combination of technologies to achieve your IAQ goals.


HVAC filters deter large organic compounds like mold spores and pollen. That’s why more and more buildings are turning to a purification technology called UVGI as a way to mitigate smaller microorganisms, such as fungi, bacteria, viruses and more. UVGI, or Ultraviolet Germicidal Irradiation, uses short wavelength ultraviolet light (UV-C) to sterilize the microscopic contaminants that filtration systems miss. Designed to operate in both unoccupied spaces and in-duct environments, UVGI is a versatile extra layer of protection against airborne health risks in your building.
