Why Ductwork Repair Matters
Ductwork is the silent workhorse of your HVAC system. It is responsible for transporting heated or cooled air from your furnace or air conditioner to the various rooms in your home. When ductwork is functioning properly, it ensures that your HVAC system operates efficiently, providing consistent temperatures and optimal air quality. However, when ductwork is damaged or poorly maintained, it can lead to a host of problems, including:
Energy Waste: Leaky ductwork is a major source of energy waste. According to the U.S. Department of Energy, duct leakage can account for as much as 30% of a home’s total energy loss. This means that you are paying to heat or cool air that is escaping into unconditioned spaces, such as attics, crawl spaces, and wall cavities. Repairing ductwork leaks can significantly reduce your energy bills and lower your carbon footprint.
Uneven Temperatures: Leaks and blockages in ductwork can cause uneven temperatures throughout your home. Some rooms may be too hot or too cold, while others may be just right. This can be uncomfortable and frustrating, especially during extreme weather conditions. Ductwork repair can help to ensure that all rooms receive the proper amount of conditioned air, creating a more consistent and comfortable indoor environment.
Poor Air Quality: Damaged ductwork can allow dust, pollen, mold spores, and other contaminants to enter your home’s air supply. This can trigger allergies, asthma, and other respiratory problems. Additionally, leaky ductwork can draw in air from unconditioned spaces, which may contain harmful pollutants. Repairing ductwork can help to improve indoor air quality and protect your family’s health.
HVAC System Strain: When ductwork is leaky or blocked, your HVAC system has to work harder to maintain the desired temperature. This can put a strain on the system, leading to premature wear and tear and a shorter lifespan. Repairing ductwork can help to extend the life of your HVAC system and prevent costly repairs or replacements.
Increased Humidity: Leaky ductwork can also contribute to increased humidity levels in your home. This can create a breeding ground for mold and mildew, which can damage your property and pose health risks. Repairing ductwork can help to control humidity levels and prevent mold growth.
Common Ductwork Problems
Ductwork can experience a variety of problems over time. Some of the most common issues include:
Leaks: Leaks are the most common ductwork problem. They can occur at joints, seams, and connections. Leaks can be caused by age, wear and tear, poor installation, or damage from rodents or insects.
Cracks: Cracks can develop in ductwork due to age, temperature fluctuations, or physical damage. Cracks can allow air to escape and contaminants to enter the air supply.
Disconnections: Ductwork sections can become disconnected over time, especially in areas with poor support or high vibration. Disconnections can cause significant air leaks and reduce the efficiency of the HVAC system.
Blockages: Ductwork can become blocked by dust, debris, or rodent nests. Blockages can restrict airflow and cause the HVAC system to work harder.
Improper Insulation: Ductwork that is not properly insulated can lose heat in the winter and gain heat in the summer. This can increase energy bills and reduce the efficiency of the HVAC system.
Sagging or Collapsed Ducts: Over time, ducts can sag or collapse, especially if they are not properly supported. This can restrict airflow and reduce the efficiency of the HVAC system.
Mold Growth: Mold can grow in ductwork if there is moisture present. Mold growth can contaminate the air supply and pose health risks.
Signs You Need Ductwork Repair
It is important to be aware of the signs that your ductwork may need repair. Some common indicators include:
Increased Energy Bills: If your energy bills are higher than usual, it could be a sign that your ductwork is leaking air.
Uneven Temperatures: If some rooms in your home are too hot or too cold, it could be a sign that your ductwork is not distributing air properly.
Dusty Air: If your home is unusually dusty, it could be a sign that your ductwork is leaking air and drawing in dust from unconditioned spaces.
Allergy Symptoms: If you or your family members are experiencing increased allergy symptoms, it could be a sign that your ductwork is contaminated with dust, pollen, or mold spores.
Strange Noises: If you hear strange noises coming from your ductwork, such as whistling, banging, or rattling, it could be a sign that there is a problem.
Visible Damage: If you can see visible damage to your ductwork, such as leaks, cracks, or disconnections, it is important to have it repaired promptly.

The Ductwork Repair Process
The ductwork repair process typically involves the following steps:
Inspection: A qualified HVAC technician will inspect your ductwork to identify any leaks, cracks, disconnections, or other problems. They may use specialized equipment, such as a duct leakage tester, to measure the amount of air leaking from your ductwork.
Cleaning: Before making any repairs, the technician may clean your ductwork to remove dust, debris, and other contaminants. This can help to improve air quality and ensure that the repairs are effective.
Sealing: The technician will seal any leaks or cracks in your ductwork using a variety of methods, such as duct tape, mastic sealant, or aerosol sealant.
Insulation: If your ductwork is not properly insulated, the technician may add insulation to help prevent heat loss or gain.
Repairing or Replacing: If any sections of your ductwork are severely damaged, the technician may need to repair or replace them.
Testing: After making the repairs, the technician will test your ductwork to ensure that it is properly sealed and that the HVAC system is operating efficiently.
Types of Ductwork Repair Techniques
Several techniques are used in ductwork repair, each suited to different types of problems and duct materials:
Sealing with Mastic: Mastic sealant is a thick, paint-like substance that is applied to joints and seams to create an airtight seal. It is one of the most effective methods for sealing ductwork leaks. Mastic is flexible and durable, making it ideal for sealing gaps and cracks in metal ductwork.
Using Metal Tape: Metal tape, also known as foil tape, is a strong, heat-resistant tape that can be used to seal small leaks and cracks in metal ductwork. It is important to use metal tape specifically designed for ductwork, as regular duct tape is not as effective and can deteriorate over time.
Aeroseal Technology: Aeroseal is a patented technology that seals ductwork leaks from the inside out. It involves injecting a non-toxic aerosol sealant into the ductwork system. The sealant particles are attracted to the edges of leaks, where they accumulate and form a seal. Aeroseal is a highly effective method for sealing hard-to-reach leaks.
Duct Replacement: In cases where ductwork is severely damaged or deteriorated, replacement may be necessary. This involves removing the old ductwork and installing new ductwork in its place. Duct replacement is a more extensive and costly repair, but it can be the most effective solution for ensuring optimal airflow and air quality.
