Ductwork Replacement in Jacksonville, FL

Ductwork helps to distribute airflow from your HVAC system throughout your home. The quality of your ductwork will affect the efficiency of your system and your comfort. Your ducts are an essential part of your HVAC system, even though most people do not pay attention to them. There are three types of duct systems, including rigid ductwork, semi-rigid ductwork, and flexible ductwork.

Flexible Ductwork

Flexible ductworks usually have a tube-like shape and consist of a wire coil covered with flexible and sturdy plastic. It is also surrounded by a layer of insulation. Flexible ductwork is best suited for tricky spaces where you can’t install rigid ducts.
Flexible ductwork has certain requirements for installation. For example, you have to secure and support the ducts sufficiently to prevent snaking or sagging. You also have to avoid kinks and turns as this can constrict airflow and lower the efficiency of your HVAC system. On the other hand, flexible ductwork is easy to install and cheaper than rigid ductwork.

Rigid Ductwork

Rigid ductwork is available in various sizes and materials. It is usually insulated and can either be cylindrical or rectangular. These ducts are commonly used since they are durable, reliable, and long-lasting. There are three types of rigid ducts, including sheet metal ducts, fiberglass-lined ducts, and fiberboard ducts.

Sheet metal ducts are mostly made of galvanized steel and aluminum. Aluminum is used since its lightweight and has easy installation. These materials have non-porous surfaces making them impervious to mold growth.

Fiberglass-lined ducts have internal fiberglass lining. They are similar to sheet metal ducts except for fiberglass, which can dampen noise from the air conditioner. However, the lining can deteriorate over time, releasing fiberglass particles. These particles pose a health risk when exposed for a long period. The lining also makes it harder to clean the ducts as you can release the fibers. Fiberglass-lined ducts are susceptible to mold and bacteria, which can lower your indoor air quality.

Fiberboard ducts use resin to compress and bond fiberglass strands. A foil laminate sheet covers the strands to protect them from moisture. These ducts are well insulated and can be used for both heating and cooling. However, they are prone to mold growth, which can affect your indoor air quality. Additionally, their rough surface can restrict airflow and the efficiency of your system.

Semi-rigid Ducts

Semi-duct ducts have numerous benefits and are considered the best ventilation ducts. They enhance the efficiency of your ventilation system and do not have any leakages. They are also sturdy and cannot be crushed easily. Some semi-rigid ducts are versatile and can switch between oval and round ducting while preserving hydraulic pressure loss and maintaining system performance. Additionally, they are easy to maintain since they have anti-static and anti-bacterial linings.

Benefits of Efficient Ductwork

When your home has efficient ductwork, you will enjoy uncompromised comfort. It will provide the right amount of conditioned air. When your ducts are properly sealed, they maximize airflow and prevent outdoor air from entering your indoor air.

Your ducts should have a proper balance between the supply and return airflow to maintain the indoor pressure. They should also be properly designed and sized to circulate air efficiently.

Signs Your Air Ducts May Need Replacing

Proper airflow ensures that all rooms are sufficiently cooled or heated. If your ductwork is faulty, then you will experience poor airflow. Some rooms will be cooler or warmer than others. These cold and hot spots can lead to mold growth and discomfort. Your AC will also strain to heat or cool your home leading to high energy bills.

Dirt, debris, and clogging in your ductwork can constrict your airflow, making it difficult for air to circulate to all the spaces. If you notice this, you may have to replace your ductwork to restore efficiency and comfort.

Inadequate Heating or Cooling

If your AC is having trouble heating or cooling your home, you may have to get your ducts inspected. Leaks in your ductwork and poor insulation can lower the efficiency of your HVAC system. You can have a licensed technician inspect your ducts to find and fix the problem. The technician may recommend that you replace your ductwork for proper heating and cooling.

Dents and Punctures

Your ducts are strategically placed and hidden from view to protect them from physical damage. Over time, the ducts can suffer from damage and punctures that may lead to leakages. This also lowers the efficiency of your HVAC system.

Damages to your ducts can happen when undertaking home projects or when you exert pressure on the ducts. Pests can also find their way into the ducts and puncture holes. An HVAC technician can conduct repairs to your ducts, but eventually, you may have to replace your ducts.

Molds and Odors

Molds can cause serious health issues, especially to family members who suffer from allergies and asthma attacks. If you notice mold growth in your home, your ductwork may have issues. The molds also produce a foul odor that can affect your comfort at home. When ducts are not supplying adequate air, some rooms will experience condensation, which encourages mold growth. You should get the mold removed and replace your air ducts to prevent further growth.

High Energy Bills

When your HVAC system is overworking to cool your home, it uses more energy, which is reflected in your electricity bill. Faulty ductwork can make your system strain to cool or heat your home. Replacing your ducts will save you money in the long run by lowering your energy bills.

Noisy Operation

Your ducts do not usually produce noise while operating. However, if your ducts have problems such as clogs or damaged components, they may produce noise while they operate. The ducts may also vibrate too much as they circulate the air. If your air ducts are making odd noises, you may need to replace them.

Increased Dust

You may notice that your house is becoming increasingly dusty. When your ducts are clogged, they may circulate dust through your home. Dust can also enter your ducts through holes and gaps. Repairing your ducts can prevent the issue, but replacing them will ensure you eliminate the issue entirely.


Air ducts can last to about 10 years with proper care. After this time, their efficiency may decrease, and they may start developing problems such as broken seals, poor insulation, and reduced airflow. These problems will affect your health and comfort at home. Increased wear and tear in your ducts will also lead to high energy bills and frequent repairs. It’s crucial that you have your ducts replaced every 10 years.
