What is Air Balancing and Why Does It Matter?

Commercial Air Balancing

Man working on air balancing an HVAC system

No matter the temperature outside, you want to be comfortable inside. When your HVAC system is properly balanced — with all of its components working together efficiently — that means a steady year-round temperature in every room, the right amount of airflow, and predictable energy bills.


But what happens when your HVAC is out of whack? You may notice fluctuating temperatures between rooms, drafts or hot spots, too-high humidity, and other issues that lead to discomfort. Unfortunately, an unbalanced system can also create safety risks.


The solution lies in commercial air balancing.


Why Air Balancing Matters?


An unbalanced HVAC system leads to positive or negative air pressure issues. It's all about achieving even airflow throughout the building... but even well-maintained systems can experience pressure issues.

How do you know if your system is off-balance? Along with drafts, hot or cold spots, and increasing humidity, you may notice:


  • Whistling sounds
  • Doors that open and shut by themselves
  • Doors that are difficult to close
  • Condensation on the inside of windows
  • Rooms that feel stuffy or stale
  • Rising energy bills
  • Frequent hot and cold cycling


Uneven air flow can lead to uncomfortable conditions. But an unbalanced system can also increase risk to both property and health. High humidity levels encourage mold and mildew growth, and can lead to pollen and dust build-up, all of which can negatively impact respiratory health.


Benefits of Commercial Air Balancing


Commercial air balancing will allow your HVAC system to distribute air effectively and evenly throughout the building. This eliminates negative or positive pressure spots — and that means greater comfort. In other words, no more hot spots in summer, no more unpleasant drafts that lead to mysteriously closing doors, and no more chilly rooms in winter.


A balanced system also means better indoor air quality. Reduced humidity levels don't just result in a fresher, more pleasant atmosphere (although that's another benefit of commercial air balancing). A balanced system also means fewer containments, like mold spores, pollen, or dust to trigger allergies and respiratory issues.


Finally, a commercial air balancing service will help lower energy bills. A balanced system means consistent temperatures throughout the building, so your HVAC system will cycle less. Plus, no one will need to crank the A/C or heat to compensate for fluctuating temperatures.


Commercial Air Balancing Explained

The commercial air balancing process incorporates three components that incorporate testing, adjustment and balancing:


  • Testing assesses HVAC performance by measuring temperature, pressure, velocity, rotational speed, electrical characteristics, and air and water quality
  • Adjustment achieves the best possible efficiency by optimizing device performance
  • Balancing regulates optimal air flow by correlating all components of the HVAC system, so they work in harmony
