Air balancing is critical to the proper operation of a forced-air system, such as a furnace, heat pump, or central air conditioner.
Many homeowners believe that their HVAC system covers their entire house consistently with cool or warm air as required. That is not true. Any forced-air system consists of several distinct components and controls. And when those elements become out of sync, your energy bills can skyrocket, and your home becomes less pleasant. Air duct balancing services may be beneficial in this case. If you’re wondering what it is exactly and how to balance air ducts, keep reading.
What Is Air Duct Balancing
Duct flow balancing is the process of modifying an HVAC system so that each room in the house receives the appropriate quantity of conditioned air (hot or cold, depending on the season). When installed, all residential HVAC systems should be balanced. It is not unusual for them to require adjustment on occasion.
In an ideal world, if you set your thermostat to 72 degrees Fahrenheit, every room in your home should be warmed or chilled to 72 degrees Fahrenheit. Unfortunately, this is not always true! Many homeowners discover that heating or cooling one floor results in the other floors being overly hot or cold. At times, specific rooms never seem to match the rest of the house’s temperature.
Why They Need To Be Balanced
This may come as no surprise, but there are significant benefits to air duct balancing services. The following are the primary advantages:
Reliable Temperatures: Yes, this is self-evident, but it is the most critical reason. As previously said, air balancing guarantees a steady flow of air into each space within a house.
Enhanced Comfort: To maintain a comfortable temperature within your home, the temperatures in each room should be consistent with the thermostat settings. Air balancing ensures that the appropriate quantity of airflow enters and exits those rooms, preventing your loved ones from becoming overly hot or chilly.
Improved Air Quality: A balanced HVAC system helps safeguard against the unexpected inflow of outdoor air, which is frequently contaminated with allergens and contaminants. A properly sealed building protects the filtered air contained within, which is just as critical for your health as purifying your drinking water.
Boosted Energy Efficiency: A properly configured HVAC system ensures even airflow throughout your home. When consistent temperatures are easily maintained, HVAC systems do not have to work as hard by operating for extended periods of time, saving you money while also helping the environment.
Longer HVAC Lifespan: HVAC units are not given an easy ride. They are always up against the extremes of hot and cold weather, and the extremes take a toll on them. To keep your HVAC system in good working order, balancing duct system should be a primary priority.
How To Determine If Your Home Needs Air Balancing
Balancing airflow in ducts is beneficial because it provides a more comfortable living environment and operates more effectively than one that is unbalanced. The following are four indicators that you require air duct balancing services:
- Hot or cold spots that persist in specific rooms
- Heating and cooling bills that continue to rise
- Individual vents that have difficulty supplying air, even with the vent damper open
- Temperature differences between floors of greater than two degrees
How To Balance HVAC Ducts
To guarantee that your HVAC duct balancing goes as smoothly as possible, the professional airflow technician should perform the following:
- Calculate the tonnage or heating output of the system, which provides the required total system airflow.
- Distribute that number among the total number of rooms using complex engineering calculations that consider the room’s size, location, and furnishings. This provides them with information on the airflow in each room.
- Examine the building’s design to gain a better understanding of the room placement and airflow path.
- Conduct an inspection and start-up of the HVAC system to verify that it operates at peak efficiency.
- Take readings of the delivered airflow using specialized equipment — first for the entire system and then for each room in the house — and compare them to the needed airflow calculations to determine whether there are any discrepancies.
