A properly functioning HVAC system does more than just heat or cool air; it also circulates that air throughout a building via undersized ductwork. To do this effectively, the ductwork in a place must be correctly designed and fitted based on the HVAC system’s requirements.
But how does one go about ductwork sizing? How do you determine the correct ductwork size for a given space? Allow the undersized ductwork experts at dryer vent cleaning Atlanta to assist you!
The right quantity of heating or cooling for a particular room is essential for an efficient HVAC system. This translates to a room or a whole house that is comfortable to live in without consuming more energy than necessary.
HVAC repair specialists use load calculations to calculate how much heat or air conditioning a home actually needs.
Let’s take a look at the steps involved in this procedure:
What Is A Load Calculation And How Does It Work?
A load calculation, in essence, determines how much heat (or air conditioning) a space will need. Technicians use the term cubic feet per minute of airflow (CFM) to express it.
What Factors Go Into Load Calculation?
An HVAC service technician will perform room-by-room load calculation of the entire residence or space. This data is fed into the Manual J protocol, which determines the load for the entire space.
What Does Duct Size Have To Do With Load Calculation?
After that, the technician compares the load calculation (space heating need) to the furnace or air conditioner’s output capability.
Moreover, he may also use char to determine the proper duct size for the space using this “output versus requirement” calculation.
Hopefully, everything goes as planned and the calculations are accurate. But what if the undersized ductwork is sized incorrectly, for example, too small?
Here are a few scenarios to consider:
Call For The Duct Inspection
Undersized ducts will raise static pressure, resulting in excessive noise as the air travels through the system. It is often loud enough to be distracting, so it will be easy to overlook. However, undersized ducts overwork the heating unit and should be rectified.
The undersized ductwork That Is Too Big
A duct that is excessively large, on the other hand, will result in less warm or cooled air reaching the targeted location. This could suggest that the rooms aren’t properly cooled. This puts a strain on the heating or cooling system, which must work overtime to meet the unmet demand.
Inadequate returns could also be caused by incorrect duct sizing or layout. Not enough air is taken from the room back into the HVAC system due to improper duct architecture or insufficient return vents. The result is uneven air pressure and stuffy, inadequately ventilated spaces.
How To Identify Bad Ductwork | Signs Of Poorly Installed Air Ducts
Air comes in through supply ducts and out through return ducts every time you turn on the heating or air conditioning system. Supply ducts are the arteries (bringing blood to the heart) and return ducts are the veins if your HVAC unit is a heart (carrying blood back to the heart).
The air ducts that run throughout your house are an important part of your HVAC system. Unfortunately, you might be shocked by how many HVAC and ducting systems are installed incorrectly.
“More than half of new systems in U.S. homes do not operate to their rated efficiency as a result of faulty installation,” according to Experts. High energy expenditures, reduced performance, poor indoor air quality, and poor air distribution are all consequences of improper HVAC sizing and installation. You will surely have inferior indoor air quality and higher energy expenses if your ductwork has a lot of air leaks and poorly designed duct systems than those who have sealed and insulated ducts.
Signs Of A Wrongly Installed Duct
The following are some of the most prevalent indications of faulty ducting installation. To remedy any of the duct issues listed below, contact a skilled HVAC provider.
Leaks In The Air Ducts
“About 20% of the air that passes through the duct system is lost owing to leaks, gaps, and improperly linked ducts,” according to experts. Your HVAC system has to work harder because of ductwork leaks. Negative air pressure can draw in dirty air as well as clean air if you have not sealed tha ducts properly.
Basements, crawlspaces, garages, and attics are particularly vulnerable to air duct leakage.
Examine all of your air duct seams for cracks, gaps, and weak connections. If you fear your ducts are leaking, consider hiring a professional to seal them.
You may have ductwork with significant leaks if you have allergies or other problems related to an excessive amount of dust. Your ductwork leaks not only let conditioned air out, but also let air, dust, and debris in.
Signs Of Leaking Air Ducts:
The following are signs of leaking air ducts:
- Energy bills that are too high
- It’s difficult to heat or cool a room.
- Rooms appear stuffy and unwelcoming.
- Basements, attics, crawlspaces, and garages all have ductwork.
- You detect ducts that are twisted, loose, collapsed, or broken.
Schedule duct testing if you observe any leaking air ducts. Your HVAC specialist will compress the duct system in order to find any leaks.

Inconsistent Room Temperatures, Hot And Cold Spots
You may have inadequately sized ductwork or airflow issues if you are having hot and cold patches and other comfort issues.
Undersized ducts and grilles may restrict airflow, which could be the source of your comfort and temperature issues. You may have incorrectly sized ducts or blocked vents and registers if you notice noisy airflow and odd noises like whistling and popping.
Contact air duct cleaning Atlanta if you notice any drooping flex ducts and want to make sure everything is stable and working properly.
Check the following in addition to the air ducts for kinks and damage:
- The air filter should be clean.
- You may require a 2-foot clearance around the exterior condenser unit.
- Vents and registers that are open and unhindered
- Flex ducts require at least one support every 4 feet.
Experts recommend Professional heating and air conditioning maintenance once a year.
In conclusion, we can say that undersized ducts pose a serious threat to your HVAC system. Therefore, you need to detect them and repair them as soon as possible.
