HVAC Ducts: Airflow, Efficiency, & Sanitation – Problems Solved



Air ducts are an essential part of the home’s HVAC system, acting as the transportation of conditioned air from the furnace or coil to the various rooms in the house. The design, size, and material of the ductwork can greatly affect the efficiency of the system. Air ducts can be made of metal, fiberglass, plastic, or a combination of materials, and may be either round or rectangular in shape. In order to ensure that air is evenly distributed to all parts of the home, air ducts must be properly insulated and sealed.

Unfortunately, air ducts can become damaged or worn over time, leading to poor airflow, higher energy costs, and air quality concerns. The good news is that Beluga Air can help you identify and address any issues with your air ducts, from duct sealing and modifications to installing zoning systems that can help you better control the amount of airflow in each room. With the right solutions, you can enjoy maximum comfort and efficiency in your home and save money on your electric bills.

How To Know If You’re Having Duct Issues?


Duct problems are usually relatively easy to diagnose. A telltale sign is that only certain vents will have low pressure, or the air coming out of certain vents won’t be cold like the rest. Another big giveaway is a change in airflow. If a certain room used to get great air and stay cool but isn’t anymore, you likely have a duct issue.


Air ducts can sometimes develop a smell, this issue can also be caused by an issue in the air handler, making this issue a little more difficult to diagnose.

Types of Air Ducts

Air ducts come in a variety of shapes and sizes, but the most common types are sheet metal, flexible, and fiberglass. Sheet metal ducts are used for larger applications such as commercial buildings, while flexible ducts are more suitable for smaller homes and apartments. Ducts can also be made from fiberglass, which is a lightweight and cost-effective option. Different types of ducts have different characteristics that must be taken into account when considering which type is best for the project. For example, sheet metal ducts are very durable and have a long life expectancy, but they are also more expensive and require specialized installation. Flexible ducts, on the other hand, are less expensive and easier to install, but they require more frequent maintenance. Choosing the right type of air duct is important to ensure the quality and performance of the HVAC system.

Beluga Air can assist you in selecting the right air ducts for your home or business, as well as properly installing them for optimal performance. Our team of experts has the experience and knowledge to help you make the best decision for your needs.

HVAC Zoning Systems

A zoning system is a great way to control the temperature of your home and ensure that each room is receiving the right amount of airflow. Zoning systems are designed to divide the home into different zones and each zone will have its own temperature control settings. This is ideal for homes that have multiple levels and rooms with different temperature needs. Beluga Air offers high-quality zoning systems that are designed to provide comfort and energy efficiency. Zoning systems allow you to save money on your energy bills by increasing airflow to the areas that need it the most and reducing airflow to areas that are already heated/cooled to the appropriate level.

Common Problems With HVAC Ducts


One of the most common issues homeowners can face with their HVAC ducts is leaks in the ductwork. An air leak can cause a loss of air pressure, which can lead to dust, dirt, and other pollutants entering your home. Leaks can also cause an increase in utility costs, as air is continuously escaping the system. Leaks happen when the air pressure inside the system is too much, or the ducts were damaged.

One of the most common causes of Duct damage is duct cleanout services. We get consistent calls from people who have recently hired a duct cleaning company and now have reduced airflow. Flex Ducts should never be cleaned because they are so soft and easy to puncture. Plus the cost of cleaning a flex duct is often almost equivalent to replacing one. If you have a leaky duct or suspect you have a leaky duct we can send someone out for free to assess the issues and get it patched up or replaced for you as soon as possible.


Another common issue is inadequate duct insulation, which can lead to poor air quality and increased energy costs. Ducts should be insulated properly to keep the air from your unit as cold as possible until it reaches its destination.

Installation & Age

Additionally, if the ducts are installed improperly, they can become noisy and reduce airflow.

Lastly, the wear and tear of everyday use can cause a buildup of dirt and debris in the ducts. This build-up is made worse by bacteria and viruses that will grow and create more blockages as well as make you sick and cause funky odors.
