Air Duct Sealing Services in San Marcos, TX

Duct Sealing Without Cutting Corners

According to Energy Star, a typical home loses as much as 20%-30% of conditioned air due to leaks, holes and poorly connected ducts. That's a lot of hard-earned money going out the window, literally! At Reliable Air, we work hard to ensure every last bit of conditioned air stays where it belongs. And we do that by not cutting corners: using the absolute best sealant products, having the best-trained technicians and performing the most thorough job possible. Call us today for your duct sealing and get:

  • Reliable people—Since we constantly train our duct sealers, you can be 100% confident that your job will be done right the first time.
  • Reliable scheduling— With same-day service and 2-hour scheduling windows, you'll get your ducts sealed at a time that's convenient for you.
  • Reliable relationships—Many of our employees stay for 10+ years so you'll always hear a familiar voice on the phone or see a familiar face at your door.

How It works

How we work in 5 easy steps

  1. Schedule your duct sealing

    Schedule an appointment online or call us at 512–396–8183. We offer 2-hour scheduling windows to ensure the least amount of disruption to each customer's day.

  2. Notify you before we arrive

    One of our expert duct sealers will call you 30 minutes prior to their arrival. That way, you know exactly who'll be arriving at your door. And if you're out and about, you can get home in time for their arrival.

  3. Give you a price

    Once your duct sealer arrives, they’ll perform a preliminary inspection of your ductwork and give you an upfront quote before any work begins. No guessing. No surprises.

  4. Seal your ducts

    After you give us the green light, we'll get to work sealing your ducts. Our team of duct sealers follows the highest industry standards on every job. Most sealant jobs take around 4 hours depending on the home and the state of the ducts.

  5. Make sure you're happy

    We don't just dine and dash. After the work, we call to get your feedback so we can ensure you're 100% satisfied.

"They are highly recommended!"

"Reliable Air has been very accommodating to our church's schedule needs. They have also given us some business rewards for doing a maintenance contract with them. Super friendly too! They are highly recommended!"

-Carol J.

"Techs are always respectful"

"They’re just like the name: Reliable. Helps me keep my older unit working. Their response is always helpful and when they come, the tech is always respectful of having to invade my workspace in order to access the unit. Explain the problem clearly as well as the cost. Willing to come back if needed to make sure the problem is fixed. Thanks."

-Ann F.
