Common Types of Air Ducts

Before addressing any issues with your air duct system, it’s essential to understand the different types of air ducts commonly found in residential HVAC systems

Flexible Air Duct(supply/return)

This type of duct consists of a flexible tube made of round wire coil, wrapped with fiberglass insulation, and covered with polymer plastic. It comes pre-insulated and ready to install as one piece, offering flexibility in routing through tight spaces.

Hard supply air ducts are primarily constructed of aluminum. Unlike flexible ducts, these rigid tubes require manual insulation after installation. They offer durability and longevity, especially in areas with higher air pressure requirements.

The main trunk serves as the primary air distribution pipe, connecting directly to the furnace or air handler. It distributes air to supply ducts that feed registers throughout the house. Main trunk ducts are typically larger in diameter than supply ducts and are commonly made of metal, although flexible options are also available.

Dryer vent ducts are solid 4-inch rigid pipes that extend from the dryer through crawl spaces or attics to exhaust heat and moisture outside the house. Proper installation and maintenance of dryer vent ducts are crucial for fire safety and efficient dryer operation.

These ducts are dedicated to venting air from bathroom and kitchen exhaust fans to the outside of the house. They typically consist of rigid or flexible ducting material and help remove excess moisture, odors, and airborne contaminants from these areas, improving indoor air quality and preventing mold and mildew growth.

Common Issues with Air Ducts

Leaky Ducts

Leaks in air ducts are a common problem that can result in significant energy loss. These leaks allow conditioned air to escape into unconditioned spaces such as attics or crawl spaces, leading to higher energy bills and reduced comfort levels.

Mold and Mildew Growth

Moisture buildup within air ducts can create an ideal environment for mold and mildew growth. Not only can this impact indoor air quality, but it can also pose health risks to you and your family, especially for those with respiratory issues or allergies.

Energy Inefficiency

Inefficient air ducts can lead to wasted energy and increased utility costs. When ducts are poorly insulated or improperly sealed, conditioned air may not reach its intended destination, resulting in overworking of the HVAC system to maintain desired temperatures.

We recently hired Northwest Crawl Space Services to perform a complete remediation of our crawl space which had a rodent infestation. Lior initially came out and did a thorough assessment and explanation of what work needed to be done. He was very detailed in explaining all work that they would do and the subsequent follow up visits and warranty that was included in the price. The following week Robert and his crew came out to perform the work. They were punctual, courteous and extremely professional in every way. They took caution and care to make sure that the inside of our house was properly masked off and protected as they removed the entirety of the contaminated crawl space insulation etc. Robert provided me with detailed pictures of the finished work and as well as pictures of a couple water pipes that had very small leaks, which I greatly appreciated. As promised, Lior came back out two weeks later to inspect all work and make sure that there were no problems. I highly recommend Northwest Crawl Space Services!

Lior and his team were fantastic. They were cheaper than the big name companies and didn't try to upsell me to repairs that didn't need to be done. They took care of the problem quickly and were great with communication and photos of the project as it was being completed. They owner even did a follow up the next day to make sure the job was done correctly. I had a list of questions when the job was done and he already had them all addressed with pictures and videos of everything. They are locally owned and operated which is very important to me. Would highly recommend

NW Crawlspace is an exceptional company. Matan and his team are experts at repairing Crawlspaces and protecting you from rodent and water Intrusion.. Rob and Leonardo and the team take the quality of their work personally. They are going to do it right and come back to check it for you. We needed a total clean out and sump pump system installed.They worked super hard to have it done by Thanksgiving. We feel like we got a bargain after seeing all that was done. I recommend them if you want your crawlspace worked on or inspected. You will be glad you called them.

We had a sump pump fail and ended up with a crawlspace that had at least two feet of standing water. Matan of Northwest Crawlspace Services came out to inspect. After examination, he carefully explained our problem and his proposed solution using easy-to-understand, non-technical language, and then gave us a firm price quote. His professionalism made us feel very much at ease and gave us assurance that we were in good hands. The very next day, a worker was sent to pump the water out of the crawlspace so that work could begin. After the water was gone, a crew of three workers was dispatched to begin the work. Before doing anything, they took great care to install plastic sheeting to protect all of the walls and floors leading up to the crawl space access door. The crew worked diligently throughout the day and completed most of the work. Afterwards, they thoroughly cleaned up, leaving little sign that they had even been there. The following day, they came back to finish the work and replace some duct work that had been damaged by the flooding. A little later, a separate person (presumably a supervisor) came by to inspect the job. We are thoroughly satisfied by the work of Northwest Crawlspace Services and would highly recommend them to other homeowners.
