How Ductworks Work
Ducts are a critical part of your heating and cooling delivery system and should be well-considered during construction. We see many systems with 90% efficient furnaces and 50% efficient duct systems. There are a few do’s and don’ts that you need to know for proper work of the duct system
Heat loss calculation determines proper duct size of the entire house and individually for “problem areas”. Problem areas include rooms over garages, knee wall rooms, rooms with high ceilings, rooms built over vented crawlspace, or any room configuration that have high exposure to elements. It is a good idea to slightly oversize ducts for problem areas.
As much as possible, ductwork must be inside! It is best to keep ducts out of the attic, but if a short attic run is essential, this run should be low on attic floor, with proper insulation over the duct after sealing all joints and seams with high-quality sealant.
In situations where ductwork must be located in an exterior cavity such as garage ceiling or exterior wall, it is best to have rectangular or oval duct to make physical contact with the interior, heated surface. This way maximum amount of insulation is installed on cold side of duct keeping it as warm as possible, like for water pipes to prevent freezing.
Causes of Faulty Ductwork
There may be many causes for leaky or cracked air ducts. Most common cause is exposure to regular temperature extremes. Air ducts are concealed within walls and tucked into other inaccessible spaces within your home. Ducts are usually not covered with insulation or protected by other barriers that shield most of your house from outside elements.
The older ductwork gets, the more likely it is to suffer fissures, leaks and small cracks. Duct leakage can be responsible for up to 30% of air lost in your ducts. Duct leakage is a significant drain on your expenses and causes uneven heating and cooling throughout your home.
Signs of Needing Air Leak Test
Damaged ductwork can be difficult to detect. Most of the ductwork is in fact hidden behind walls, under floors or in attic crawl spaces. There is no practical way to visually inspect entire duct network to identify tears, corrosion or other problems with the system.
There are, however, a few technical indicators that can alert about damaged air ducts:
- Fallen duct insulation
- Furniture blocking register
- Furnace and filter slot duct failure
- Kinks in ductwork restrict airflow
- Leaky duct connection
- Supply leaks
- Return leaks
In addition, there are also some non-technical signs that will help you determine the need for air leak test. When your home seems particularly dusty, smells musty, or has unusually high energy bills, it is good time to undergo air leak test, clean the air ducts and seal off any leaks or openings in them.
Do any of these seem familiar?
- Airborne pollutants
- Cold symptoms
- Flu symptoms
- Dust coming from vents
- Itchy eyes
- High humidity
- High energy bills
- Musty smell
- Respiratory problems
- Sore throat
- Stuffy rooms
- Temperature and air flow variations
Our state-of-the art equipment will detect even the smallest cracks. Call us (702) 518-4720 for a professional air leak test.

Benefits of Duct Sealing
There are many benefits of duct sealing. Most important is that your family will be breathing healthier air. Another benefit is that your energy bill will be reduced
Here are reasons to seal ductwork when it is faulty:
- Equipment longevity – when AC system works in a strained manner for a long period of time, AC unit suffers from excessive wear and tear, increase chances for breakdown and malfunction.
- Even heating and cooling – when the air coming from AC system flows without leaking, you will feel more even distribution of cooled or heated air throughout your home.
- Improved air quality – air escapes from faulty ductwork, outside pollution, odors, moisture and contaminants get in, significantly decreasing your home’s indoor air quality and protecting you from toxic airborne particles.
- Increased energy efficiency – significant air loss puts stress on AC system by forcing it to compensate for the air loss while fighting to achieve temperature set on thermostat. Sealed ductwork means more heated and cooled air getting into your rooms and reduces energy use.
- Odor elimination – when cracks in duct system are near any of plumbing vents or garage, they will pull in those unwelcome odors.
By eliminating leaks and maintaining ducts will make your ductwork and equipment last longer. This can save you time and money in the future. You want to ensure that your family is breathing in safe, clean air.
