Breathing Easy: Understanding the Role of Ductwork in Air Quality

What is Ductwork?

Ductwork is a pivotal part of a home’s heating, ventilation, and air conditioning (HVAC) system. Have you ever noticed the labyrinth of tubes on the ceilings and walls of your place of work or home? Well, that is known as ductwork, ducts, or ‘ducting.’ In other words, ductwork consists of the pipes and ducts used to carry air from the HVAC system to different rooms in a building. Thus, you can control temperature and humidity levels in different areas of your home. It is essential to maintain the ductwork in your home or workspace to keep the area safe, healthy, and comfortable.

Common Duct Problems that Can Occur at Home and Places of Work

• Leaking Ducts

It is one of the most common and pertinent problems plaguing ductwork. Leaking ducts can lead to energy loss. Leaks in the docs can occur because of poor installation of joints, which are not sealed properly with mastic sealant or aluminum foil tape. The situation can be especially problematic in unconditioned areas, such as attics and crawl spaces. To fix the issue of leaking ducts, you have to find the source of the leak and seal it up with mastic sealant or aluminum foil tape. However, if the holes and gaps are large, it is best to hire professional ductwork installation near Santa Rosa, CA.

• Long and Winding Ductwork

The second most common problem that ductwork of homes and workspaces experience is the presence of too many turns and twists. At times, the ductwork is longer than it should be, which can decrease the airflow in a residential or commercial premise. Thus, the ultimate conclusion is that the rooms in your home may not be getting enough heated or cooled air, resulting in uncomfortable temperatures.

One should consider the DIY route when dealing with long and winding ductwork. To deal with the problem, it is best to hire a professional HVAC contractor to inspect the ducts and reroute them to ensure that they are shorter and with less winding. Such assistance will ensure that your HVAC system is operating efficiently and that all the rooms in the residential or commercial premise are getting enough cooled or warm air. It is noteworthy to remember that there is no ‘one-size-fits-all’ solution when it comes to managing the issue of long and winding ductwork. For instance, the professional contractor might recommend a larger air handler.

• Improper Take-Off Placement

Takeoff is the point from where air enters the duct system from the plenum. The takeoff must be installed properly for your HVAC system to run efficiently. If not adequately placed, it can cause multiple problems such as inconsistent airflow in the room and make certain rooms too hot or cold. To deal with an improperly placed takeoff, the best solution is to call an HVAC contractor and get it relocated.

• Unsupported Ductwork Sections

Without proper support, sections of ductwork can sag and cause restrictions that impede or obstruct the airflow. The problem is all the more common in attics and basements where the ducts are not properly supported by rafters or joists. To cater to the issue of unsupported ductwork sections, opt for professional ductwork installation near Rohnert Park, CA. Expert ductwork contractors will add extra support to the sagging sections of the ductwork to ensure that the ducts are properly supported. Thus, the result is an improvement in airflow throughout your home.

• Blocked Airflow from Obstructions

The fifth problem plaguing air ducts of homes and commercial spaces is blocked airflow. Insulation and other airflow-blocking substances can cause uncomfortable temperatures in enclosed spaces. To deal with the problem, you have to remove all obstructions and make sure that your ventilation system is free of blockages. In addition, if required, you can also opt for professional assistance to inspect and get rid of blockages in the ductwork.

• Too Many Bends in the Ductwork

Too many bends in the ductwork can reduce airflow, thereby, causing the rooms to be too hot or too cold. The issue is especially common with older homes, as many of them were not designed to be compatible with efficient HVAC systems. To deal with the problem, you have to consult HVAC and ductwork professionals. They will inspect the ducts and reroute them to minimize the number of bends and ensure that the HVAC system is operating at its optimum. Thus, after the problem is solved, you will see that all rooms in your home or office are getting heated or cooled air.

• Not Enough Supplies or Return Registers per Room

Last but not least, overheated or chilly rooms can be the result of insufficient supply or return registers. This happens because the system may not be able to deliver enough air to multiple rooms, or it may not be able to draw enough air back into the return register for efficient and adequate operation. In such a context, adding extra supply and return registers is the best fix. However, such add-ons can be expensive and disruptive, as the contractor might have to remove the drywall.

Well, ductless mini-splits are another option for addressing insufficient supply and a lack of return registers, as they allow for zone-specific temperature regulation. These can be set up without requiring the demolition of walls.

Now that we have touched on the 7 common problems that ductwork in homes and offices faces, let us examine the importance of proper ductwork installation by professionals.

Importance of Proper Ductwork Installation

Ductwork installation should always be done by professionals, as it is a complex and time-consuming process. The installation crew must take precise measurements of the existing ducting, create new sections as needed, and secure all system components.

In addition, opting for professional ductwork installation near Cloverdale, CA, also means that local building codes that apply to your project will be taken care of. Thus, the culmination is a correctly installed ductwork and a safe environment. Some of the reasons why opting for professional assistance is mandatory for ductwork are –

• Proper Sizing

Sizing by rule-of-thumb results in poor HVAC performance, and professionals know this fact very well. For optimal comfort and stellar efficiency, the HVAC system must be designed keeping in mind ACCA Manual J load calculations, and the ductwork must be designed using ACCA Manual D procedures. These account for many more factors than just the size of the rooms and the square footage of the homes.

• Duct Sealing

Licensed ductwork specialists also guarantee that the connections between sections of ductwork are sealed with foil tape or mastic.

• Enhanced HVAC System Efficiency

When air ducts are blocked with dirt and debris, the efficiency of the HVAC system can be impeded to a considerable extent. Thus, the culmination will be reduced airflow and an increase in energy consumption. Professional ductwork contractors leverage specialized tools and techniques to eliminate obstructions and ensure optimal airflow, thereby improving the overall efficiency of the HVAC system.
