Air Balancing: How to Balance AC Vents?

Do you know what the best way to enjoy a clean and comfortable indoor environment is? The answer is simple. A clean and proper working HVAC system can ensure this. The HVAC units are available in varied shapes and sizes and use a complicated ventilation system to regulate temperature and ascertain the right amount of pumped air in the home. Unfortunately, though, sometimes the temperature and air quality balance between different house areas gets disturbed. So when this happens, you must know the way out. Hence, this article will be a complete guide on air balancing and how to balance AC vents. 

What is Air Balancing?

So, one excellent method is air balancing. But, you might wonder what it is? It is a procedure of adjusting and fixing an HVAC unit to circulate air across the home evenly. Machines can get out of order, so HVAC air harmonizing is crucial to ensure high operational efficiency. Therefore, this method improves airflow within the home, provides optimum temperature, and increases energy efficiency.

What are the Tips to Balance Air?

If you want to know how to balance air conditioning vents, you should read below:

Opening and Closing Vents

If you feel that your property floor temperature varies, you should partially close vents of the lower floor and open the ducts of the upper floor. It will help maintain a steady temperature.

Clean Air Filters

You should regularly clean the air filters that trap dust, dirt, and filth to improve air quality, reduce utility bills, and improve HVAC lifespan. However, if the system is completely clogged, you may hire Air Duct Sanitizing in Smyrna, GA.

Keep Your Surroundings Clean

An easy method to improve the air balance of your home is to relocate the furniture and devices blocking your HVAC unit. However, these items may create unnecessary heat and block the airflow.

What are the Professional Techniques to Balance Air?

If the above DIY techniques are not effective in fixing the air problems, you may seek the assistance of a Commercial air duct and dryer vent cleaning in Smyrna, GA. They might examine your system for particular checks:

  • Examine and Regulate Fan Speed
  • Inspect and Repair Ductwork

How to Balance the Air Vent?

Get Your System’s Design Info

Only a handful of homes have mechanical plans or particulars to follow. However, you can converse with the engineer about the appropriate info to balance your system. For this, you need to find the model number and search engineering info on the manufacturer’s website. You may also know the tonnage or heating output to calculate the required airflow, external stationary pressure rating, blower motor horsepower, and other important info for the report.

Examine and Start the HVAC Unit

Move through the system to identify any defects that are contributing to its unbalanced airflow. If you repair the defects, your system will run efficiently. For example, you may connect the detached ducts, uncover dampers, and improve duct suspension in some regions.

So, when you examine the system, enlist the nameplate data, then validate both fan horsepower and speed. Also, you must inspect air filters for any blockage.

Begin by shifting the thermostat to heat mode from cooling mode. After this, regulate the temperature setting to initiate the whole system operation. Then drill static pressure and temperature test docks before and after the air moving devices and a test dock five feet after the chilling coil for temperature measurement.

Note Down Initial Airflow Readings

When using a commercial balancing hood, measure and list the airflow from each supply register in the order you figured out on your floor plan and the balancing report. After that, calculate and note down the airflow of each return grille. If the hood does not fit on the grill, carry out an airflow transverse of the duct as per the ASHRAE Standard 111. Next, add and compute the total airflow from each supply register. And repeat the same for return grills.

Contrast Design to Real Airflows

You need to contrast your original airflow readings to the design register, grill, and system airflow. Then, adjust the fan to acquire the required system CFM. The average air harmonizing specifications should be below 10% of the design airflow.  

After this, contrast each supply and return grills to its normal airflow and identify registers where the airflow surpasses 110% of the design. Then, shut the dampers to the high airflow registers unless you attain the design airflow.

This way, you will identify the low airflow registers with improvement. After this, re-test the low registers and regulate dampers unless all supply registers are more significant or less than 10% of the design airflow.

Next, contrast return grill airflows to each grill design. Then, regulate return balancing dampers as required unless each return is greater or less than 10% of the design airflow.  

Get through the system for one last time to ensure each register and design has an optimum airflow. Then, list down your final damper settings.

Final Test

Using only the air-balancing hood for measurement is not enough to balance the HVAC unit. However, you need to do additional testing for each air balance task. Hence, many sizes must match each other.

As the air balance report offers space to list each measurement, the tests include total exterior static compression, fan speed, temperature disparity, and electrical measurement.

Each reading is contrasted to the manufacturer’s stipulations and regulated for particular part-load conditions. Hence, using equipment particulars and fan laws can be determined against airflow data to validate overall precision. Now complete the report with your derived conclusions and recommendations for better system performance.

Extra Testing and Computations

The HVAC unit performance and energy evaluation have far hidden essential balancing in recent years. Hence, you may include apparatus and system BTU measurement, system contracting steps, static pressure and temperature summaries, live duct seepage, refrigerant, and ignition tuning, building pressure examination, and many other tests to the air balance report. So, an air harmonizing report is a recommended verification test for the HVAC performance that promises comfort and peace of mind.
