Air Duct Sealing and Repair

Ductwork Sealing and Repair Services in Sterling

Our team responds quickly with a satisfaction guarantee

The ductwork in your home is an intricate system that includes supply ducts, which deliver conditioned air to different rooms, and return ducts, which transport air back to the HVAC system. Leaky ducts may lose so much air that air conditioner efficiency can be reduced by as much as 40%. Old ducts are most at risk, especially those in your attic or basement.

Cardinal Plumbing provides air duct sealing services in Northern Virginia to restore your ventilation system and A/C system efficiency. We serve customers in Sterling, Alexandria, Woodbridge, Lorton, Reston, Gainesville, Manassas, and other communities.

Common Problems with Air Ducts

The most common issues we see with duct systems include:

Leaky Ducts: It’s not uncommon for small cracks to develop in air ducts. These breaks can cause air to leak and draw in stale attic or crawlspace air, circulating it into the living space. A simple repair can resolve a musty smell or potential air quality issues.
Uninsulated or Poorly Insulated Ducts: With no/poor duct insulation, air can lose heat quickly as it passes through cold attic duct lines. Uninsulated ductwork can also quickly heat chilled air before it ever reaches your living space.
Imbalanced Ductwork: Poorly installed, improperly located, or misshapen ducts can affect air distribution. The result can be low temperature regulation, in which some rooms are too hot and others are too cold.
Safety: Air duct leakage can cause a pressure imbalance, which can push air from furnaces, gas ranges, wood stoves, and other combustion appliances back into your home. This can result in carbon monoxide exposure and general poor indoor air quality.

When Is It Time to Install New Air Ducts?

In terms of HVAC efficiency, sealing and repairing air ducts can improve performance. However, if your ductwork is more than 15 years old, replacing it can avoid issues such as pest infestations or collapsed ducts. If you have high energy bills and can’t explain why, leaks in ductwork may be causing you to lose energy. Small gaps or holes that allow air to leak can also let in dust, pollen, and other contaminants, which can trigger allergies, asthma, or other health problems. If you notice any of these signs, it may be time to install new air ducts.

See What Our Customers Have To Say

Christina Yount

“I was very happy with our service technician, Tommy. He sent us an e-mail & text (w/ his photo) before he arrived. He took off his shoes and wore disposable booties on his feet and was polite & respectful. He explained what we needed, in plain English, and patiently answered our many questions. He e-mailed me an estimate within 10 minutes of leaving our condo. He even paid some attention to our Cat ! My sister & I were very impressed.”

Ronnie Schulman

“I admit I had a little sticker shock when I was quoted $466 to snake a clogged kitchen drain. I did receive a $30 discount as a first time customer. That said, I was very happy with the service. They came the next day at the promised time and took the time and effort to do the job right and explain what they were doing and how to avoid future issues. They left me some solution to to pour down my drain. The plumber was professional and very courteous. I gave four stars instead of five only because I thought they were a little pricey. Nonetheless I’d use them again.”

Alison Stein

“Excellent service! I felt very well informed about all my options. The company calls, texts and emails when a service provider is on the way. I’ll absolutely recommend them and use them in the future.”

Penny Dunn

“Very pleasant experience. Shane was very nice. After I showed him what I needed, he gave me an estimated cost and after I approved the estimate, got to work. About two hours later, he was done. I was very pleased. If I hadn’t known someone had been there, I would never guessed. Very neat and tidy. Highly recommended.”

Air Duct Repair Services

A healthy HVAC unit includes having clean, properly functioning air ducts. If you have noticed a change in air quality or the efficiency of your HVAC unit, then your air ducts might be to blame.

While having clean air ducts can fix many air quality issues in your home, sometimes a damaged air duct is to blame for causing air flow problems.

Knowing how to identify issues and repair an air duct should be done by a professional. DIY work often leads to further problems down the road, and can result in a damaged HVAC unit that needs repairs or even replacement.

Benefits of Air Duct Repair

As air ducts age, they become more likely to require repairs. Poor air quality in air ducts can be a result of clogs or debris buildup.

Aside from cleaning air ducts frequently, it’s important to have them inspected for air leaks. Leaky ducts allow heated or cooled air to escape into unused spaces, and they have more entry points for dust and dirt. This can lead to faster and more frequent clogs.

Another issue of leaky ducts is poor airflow. Poor airflow in your HVAC unit can cause your unit to work harder than usual, resulting in premature HVAC repairs and replacements.

These issues can be avoided with outstanding air duct repair services from Cardinal Plumbing, Heating & Air.
