How Air Balancing Can Help Your HVAC System Run Smoothly


How can air balancing benefit your HVAC system?

You might have heard of air balancing if you received annual maintenance recently. Air balancing is when an HVAC technician uses special equipment to fix inconsistent temperatures throughout your home or business. For example, you may feel like you need a jacket in one room while burning up in another.

These temperature imbalances may cause you to struggle with setting the thermostat. Frequent thermostat adjustments are inefficient and cause your HVAC system to work harder to maintain a consistent temperature.

If you are feeling imbalanced temperatures in your house, it’s time to request an air-balancing procedure. 

Air balancing is a confusing and involved topic, so we have prepared the basics of air balancing for you. In this blog, you will learn:

  • The definition of air-balancing 
  • What happens during air balancing.
  • Why air-balancing is beneficial  
  • How you can request air balancing maintenance with us. 

If you feel imbalanced temperatures in your home, don’t let your HVAC system work overtime. Call Cardinal today for the best HVAC maintenance in Alexandria, VA.

What is Air Balancing?

Air balancing tests your HVAC system for uneven airflow or negative air pressure areas. Not only does air balancing even out the airflow in your home, but it can also spot potential problems with your system before they become costly repairs. 

The ultimate goal is to provide airflow balancing throughout all areas of your home. There are many methods of air-balancing, including ones you can DIY at home!

What Happens During Air Balancing?

Air balancing tests your system’s air pressure from all openings, including vents and registers. A technician will then use paperwork such as ductwork maps and airflow charts to balance your HVAC system through every opening.

It is a complicated and time-consuming process; however, if done correctly, it can significantly affect your home’s air quality. 

Air balancing cannot fix issues such as improperly sized ductwork and poor equipment.

What Are the Benefits of Balancing for Air Conditioning Systems?

1. Increases efficiency

Several things can cause your HVAC system to decrease in efficiency. Imbalanced air is one of them. Whenever you have to adjust the thermostat frequently to feel the correct temperature, it causes the system to work twice as hard to maintain temperatures. 

When your air is balanced, the system can keep the entire house at a consistent temperature without frequent thermostat changes.

2. Saves Money

If the temperature in your house is unbalanced, it’s usually because there is an underlying issue with your HVAC system. Imbalanced temperature also leads to further wear and tear on your HVAC system. 

When you balance your air, you can catch many expensive issues early and prevent unneeded wear and tear on your HVAC system. Air balancing your HVAC system may seem like a huge investment, but it is worth considering how much money you’ll be saving on repairs in the future.

3. Aids in your comfort

Nobody wants to be in a home where it’s hot and run one room and freezing in another. You can be sure that your home’s temperature is always comfortable when you get an air balancing. You can also have peace of mind that your HVAC system is not running up your utility bills due to temperature and pressure imbalances.

4. Aids in finding damages

Air balancing is less of a repair and more of testing on your HVAC system. When technicians conduct air balancing, they often encounter underlying issues causing temperature or pressure imbalances. 

Often, they find these issues before they become expensive damages. These underlying issues may have been causing devastating problems to your HVAC system that you didn’t even know about.

5. Increases your HVAC system’s lifespan.

Needless to say, your HVAC system will experience a longer and healthier life if it receives air balancing. With balanced air, your HVAC system runs smoothly and more efficiently to minimize repairs and perform better longer.

1. Do I need to specifically ask for air balancing as a part of my annual maintenance?

Not all HVAC companies will include air balancing as a part of annual maintenance, so it’s important to check with them that they include it. 

Air balancing can be expensive depending on which procedures they conduct, so be prepared for a larger maintenance bill after adding air balancing. 

2. How do I know when I need air-balancing?

You can tell when you need air-balancing when you feel inconsistent temperature throughout your home or business. Your HVAC system should be able to heat or cool all the rooms in your building equally. 

You may also need to consider air balancing if you have weak airflow or during any of the following.

  • After installation
  • After any repairs to the HVAC system
  • After upgrades to the HVAC system
  • After large home renovations
  • When you move into a new home

3. Can I balance my air at home? 

The best way to balance your air is by contacting an HVAC technician. However, there are some things you can do to improve the airflow in your home. 

Here are a few tricks to try to balance your air:

  • Open or close your vents. 
  • Clean your air filters.
  • Check for drafts
  • Remove any items blocking registers.

If none of these methods work, call one of our expert technicians! A professional will need to balance the air in your home. Air balancing is a complicated process that requires certain documentation and training.
