What Causes Faulty Ductwork?
Ductwork is like a system of hallways where different doors lead to different parts of the building. In order to produce a comfortable indoor temperature, an HVAC unit needs to transfer both hot and cold air from the ventilation system. If the ductwork is damaged, cool air cannot travel throughout the building. During the spring, it is especially important to repair ductwork to prevent heat sickness and mold.
Does Dust Play a Role in Ductwork?
Dusty homes can lead to dusty vents. Since many older ducts have holes, what may seem like innocuous debris can form blockages inside the ductwork. Dust is known to obstruct these tunnels.
Dust occurs in every household and is not a sign of poor hygiene. It is usually made up of skin cells, hair, and clothing fibers. Even if particles are not immediately visible, it’s important to dust the windowsills, picture frames, and especially moving fans. Dusting on a weekly basis can keep ducts lasting longer.
The likelihood of damage increases with the age of the HVAC unit. Ductwork replacement is usually necessary after 10-15 years. Although ductwork may last longer, this does not mean it is cost-effective once dust has restricted the airflow.
Airflow Restriction
Airflow restriction causes the HVAC system to work harder. To tell if there is a problem, homeowners are encouraged to pay attention to household sounds. Air conditioners that constantly run in the background or operate on short cycles may be an indication of a clog.
A Total External Static Pressure Test measures the resistance to airflow. It also allows HVAC technicians to examine the static pressure found in the supply and return ductwork, air filters, and registers. If airflow is restricted, this is likely due to an air leak or hole in the ductwork.
Air leaks do not necessarily mean it is time for replacement ductwork. Depending on the age and condition of the ducts, many air gaps can be sealed. Most ductwork repairs are handled within a day using a specific metallic foil tape. This seals the gap for much longer than standard duct tape.
Dust Can Increase Utility Bills
If homeowners notice an increase in their monthly energy bill, it may be due to a large appliance. The air conditioner is often to blame. However, buying a new air conditioner will not fix the airflow if clogs are inside the ductwork.
Since air duct repair can be much less expensive than buying a brand-new air conditioning unit, dust should be considered first. Simple blockages can cause irreversible damage, but dust is easy to prevent.
When blockages form inside an air duct, air conditioners must use more energy to produce the same temperature as homes with properly functioning ACs. If the leak is big enough a home may never reach the desired temperature despite running the AC all day. To prevent poor ductwork from costing a fortune, homeowners are advised to maintain it annually. Fewer duct repair services are necessary when the insulation is regularly inspected.
