Air Balancing Myths and Facts

Have you ever scrolled through social media and seen people sharing “life hacks” that make you stop and think, “Wait, is that true?” But it’s not just the internet where these myths live, though. 

Our parents, and even friends, have passed down their little nuggets of advice over the years. Like when mom insists on turning off the Wi-Fi router before bed to “save power,” — sure, the Wi-Fi router could use a break, but does it really impact the electricity bill? Not so much. 

It’s just one of those habits that makes sense in theory… but doesn’t necessarily hold up in reality. 

Well, buckle up, because the same thing happens with your HVAC system. That’s right—air-balancing myths have been passed down like secret family recipes. We think we’re helping the system “breathe better” (or saving money), but most of us are just repeating things we think are true, but aren’t.

But here’s the kicker—these so-called “tricks” might actually be doing more harm than good to your HVAC system.

So, if you’ve ever wondered whether those tips and tricks are actually making a difference—or if they’re just another myth, stick around. We’re about to clear the air (pun intended) and bust some HVAC myths wide open.

Common Myths About Air Balancing

Unfortunately, many building owners and facility managers hold misconceptions that can lead to inefficiencies and higher HVAC operating costs. Spoiler alert: some of these might surprise you—and save you from wasting time, energy, and money in the future!

1. Air Balancing Solves All HVAC Problems

Well, the truth of the matter is that air balancing addresses airflow issues but doesn’t fix underlying problems like duct leaks, insulation issues, or faulty components. A comprehensive assessment may be needed for other HVAC problems.

2. Air Balancing is Too Expensive and Offers Minimal ROI

Commercial air balancing is an investment that offers significant returns by improving HVAC efficiency, reducing energy consumption, and preventing expensive equipment repairs. In fact, many building owners experience a measurable reduction in utility costs after balancing is completed, and it extends the lifespan of your HVAC system.

Air Balancing for Commercial Buildings

3. Air Balancing Only Affects Airflow

Air balancing impacts not only airflow but also indoor air quality and energy consumption. In commercial settings, improper balancing can lead to poor ventilation, which may affect air quality, productivity, and even violate building codes. Proper balancing ensures compliance with industry standards like SMACNA, which is critical for many commercial buildings.

4. Air Balancing is Not Relevant for Small or Older Buildings

Air balancing is important for buildings of all sizes and ages. Small buildings can also experience airflow issues that impact ventilation and energy efficiency.

Older buildings often have more complex and aging HVAC systems, which makes air balancing even more vital. Without proper airflow, older systems are more prone to inefficiencies, increasing energy bills and leading to more frequent breakdowns. Regular balancing ensures older systems operate at peak efficiency, extending their useful life.

5. Air Balancing is a One-Time Task

Commercial HVAC systems require regular monitoring and rebalancing, especially after renovations, tenant changes, or system upgrades. Continuous balancing ensures long-term efficiency and performance. Regular maintenance also helps identify and address issues before they escalate.

6. Bigger HVAC Units Mean Better Airflow

Some people believe that investing in a larger HVAC system automatically means better performance and airflow. In truth, an oversized system can short cycle, leading to poor humidity control, uneven cooling or heating, and unnecessary wear and tear. Air balancing ensures that airflow is appropriate for the size of the home and the unit.

7. Air Filters Only Need to be Changed Once a Year

While it’s often believed that air filters can last for a year, clogged or dirty filters can obstruct airflow, causing imbalances and reducing efficiency. Air balancing can only be effective when airflow isn’t being hindered by dirty filters. As HVAC experts, we recommend checking and changing filters every 1-3 months.

8. All Air Balancing Companies Provide the Same Results

The expertise and methodology of the balancing technician matter significantly. Commercial buildings often require highly customized solutions, especially when dealing with varied occupancy or advanced HVAC systems. It’s important to choose a reputable HVAC contractor with experience in commercial balancing to ensure the system is optimized for the specific building type.
