How to Tell You Need Air Duct Sealing
With the ductwork hidden from sight, how can you know to call for duct sealing? Here are a few signs to watch for that will give you a heads up that it is time to call HVAC professionals to investigate the ducts:
- A drop in airflow from the vents: Even a small leak along the ducts will cause a decline in the air pressure inside them, and this will cause a drop in the amount of airflow coming from the room vents. Call for duct specialists if you notice weak airflow when the heater or AC is on.
- Musty smells from the vents: Because ductwork runs through closed–in areas of a house that often contain large amounts of dust and dirt, they will pick up a distinct odor through any air leaks. Have strange smells from the vents looked into right away.
- High energy bills: When you notice a spike in your energy bills during a time when either the heater or the AC is running on a regular basis, the cause may be that the loss in air pressure from leaky ducts is forcing the system to work harder. Any sudden increase in your energy bill is a reason to call HVAC experts, since other problems could lie behind it.
Why You Need Professionals for Duct Sealing
No, you cannot use duct tape to seal ducts on your own. For one, it is difficult to access the ducts without training and the right equipment. For another, standard cloth–backed duct tape isn’t even useful for ducts, since it cannot stand the temperature changes that happen inside them. You must call for duct sealing technicians to handle the job. Professionals use tools such as mastic sealant and metallic tapes to provide durable sealing. They can also reach your ducts without risk of causing additional damage.
