Duct Sealing

Duct Sealing in Raleigh, NC

If your house is like most, it has a ventilation network that’s hooked up to the heater and air conditioner. A blower fan sends out the conditioned air from these comfort systems and into a series of ducts. The ducts branch out to the various room vents, distributing comfort around the building. It seems quite simple—until trouble with the ducts causes them to lose their airtight seal. Leaking air ducts will create multiple issues that will affect the comfort of your home and lower its energy efficiency.

Solving leaking air ducts takes the work of professionals to seal the holes and breaks. When you notice signs that your ventilation system is losing air, such as hot/cold spots around the house and a spike in your utility bills, call on the people who can help: Comfort Master Heating & Air Conditioning, Inc.. We’ve offered skilled work and excellent customer service to the Raleigh, NC area for more than 20 years—comfort from our family to yours!

How Bad Are Air Duct Leaks, Really?

A small leak along a stretch of metal or plastic ductwork doesn’t sound too bad. Does it really make that much of a difference to your HVAC system?

The answer is: absolutely. According to the U.S. Department of Energy’s ENERGY STAR program, air leaks in ductwork can account for a loss of up to 30% of the air circulating through the ventilation system. Think of how much that is: nearly a third of the air that you pay to either heat or cool. And it just goes to waste through these air leaks.

Furthermore, leaks in the ducts cause a drop in the air pressure throughout the ventilation system. Ducts are designed and sized to maintain specific air pressure that allows the HVAC system to work correctly. When this pressure drops, it negatively affects the entire comfort system. Airflow from the vents will start to drop and cooling/heating around the house will suffer. The holes in the vents may even start to draw in dust and other debris, which will lower indoor air quality.

The short version: If you have leaks in your ducts, you need them professionally sealed!

Why Sealing Ductwork Is a Professional Job

Wait, we know what you’re thinking: "Professionals? Why can’t I just take care of this on my own? I have the duct tape here and everything."

First, duct tape—despite the name—isn’t used for ducts. (It’s a long story, but it comes down to a naming mistake from duck to duct.) It doesn’t hold up under the temperature changes that occur within ventilation systems.

Second, unless you are a trained HVAC technician, it’s almost impossible to locate the leaks and access the ducts to fix them. Professionals use special duct testing equipment to find where the leaks are. One they’ve done that, they use tools such as mastic sealant and special metallic tapes to securely close off all the leaks so they stay closed.
