Signs Your Home’s Air Ducts Need Attention

Dusty and Stuffy Rooms

If you find that certain rooms in your home consistently feel dusty or stuffy, it could be a sign that your air ducts are in need of attention. Dust and pollutants may be entering your living spaces through leaks or gaps in the ductwork. This not only affects the cleanliness of your home but also the quality of the air you breathe.

Inconsistent Temperature

Are some rooms too warm while others are too cold? You could have blockages or leaks in your ducts, disrupting airflow and causing uneven heating or cooling.

Noisy HVAC Unit

While some level of noise is expected from an HVAC system, excessively loud or unusual sounds could indicate underlying issues with the ductwork. Improperly sized ducts or obstructions within the duct system can cause airflow disruptions, leading to increased turbulence and noise during operation. Ignoring these noises can result in reduced efficiency and potentially costly repairs in the future. Having a professional HVAC technician inspect the ductwork can help identify and address any issues contributing to the noise.

Mold and Mildew Growth

The presence of mold and mildew in your air ducts is a serious concern. Excess humidity within the ducts, often due to insulation issues or leaks, creates an ideal environment for mold and mildew to thrive. Not only does this compromise the air quality in your home, but it can also pose health risks to you and your family. Addressing mold and mildew growth promptly may require professional duct cleaning or even replacement of the affected duct sections.

JWS Mechanical & Construction Reviews by Satisfied Customers

It was a great experience working with this team for a cottage build in 2022 and 2023. JWS helped us with the majority of the construction (foundation, in- floor heating, framing, roof, siding and windows/doors).

I was really impressed with the skill & craftsmanship and felt confident my project was in good hands, which means a lot when I couldn’t be on site.

These guys have a wealth of knowledge, and care about doing a job right.

I’m very happy with the results which we’ll be enjoying for generations!

I was recommended another company for a small garage furnace install, needless to say the other company wasted 5-6 weeks of my time.

I contacted JWS and within 2 weeks they were out to install the garage furnace.

They were honest, did a great job on the install, and very fair price wise. I will be contacting JWS for future HVAC projects!

Very happy with JWS. Quick to answer my call, when I needed an on-demand water heater on Dec 28th, 2023.

Julian and John were professional, and courteous and answered all questions about my new system. I highly recommend them.

Frequently Asked Questions About Ductwork Installation and Replacement

If your ducts are old, damaged, or improperly sealed, they can lead to energy loss, uneven heating or cooling, and poor indoor air quality. Replacing them can improve efficiency, comfort, and air quality in your home. A professional HVAC technician can inspect your ductwork and advise you on whether replacement is necessary.

The best type of ductwork depends on factors such as your budget, the layout of your home, and your heating and cooling needs. Flexible ducts are often easier to install in tight spaces, while rigid ducts are more durable and suitable for long runs. Semi-rigid ducts offer a balance of flexibility and durability. Consulting with an HVAC professional can help you choose the right type for your home.

While the frequency of duct cleaning can vary depending on factors such as indoor air quality, pet ownership, allergies, and environmental conditions, it’s generally recommended to have ducts cleaned every 3 to 5 years. Regular cleaning helps remove accumulated dust, debris, mold, and allergens from ductwork, improving airflow, efficiency, and indoor air quality. A professional duct cleaning service can assess your needs and recommend a suitable cleaning schedule.
