Air Duct Sealing Services in San Marcos, TX

Cost of Duct Sealing in San Marcos, TX

Factors that affect the cost of duct sealing:

  • Amount of ductwork in the home: Larger homes, homes with multiple HVAC systems, and other factors tend to increase the amount of ductwork that needs to be assessed for leaks and damage. Paying a little extra for a thorough job matters here, because the alternative is a company that cuts corners and leaves your ducts just as leaky as they found them.
  • The accessibility of the ducts: Sealing exposed ductwork found in attics or basements tends to cost less than ductwork that's tucked away behind walls, simply because it's easier to reach.
  • Combining a sealant with insulation: If your home's ductwork is exposed (i.e. found in a basement or attic), its ability to retain conditioned air could be significantly improved by surrounding it with insulation (foam or plywood, primarily). This isn't required and costs a bit extra, but gives your ducts even greater sealed protection.

Signs you Need Duct Sealing

You may want to consider having your ducts assessed for leaks if...

  • Your energy bills are higher than normal
  • Rooms feel stuffy or humid
  • Some parts of your home feel hotter/colder than other parts

    As a contractor myself, I’ve worked with Reliable on several projects in the past. Knowing their quality of work, when I needed work on my own home I knew who to call. Arrived on schedule. Diagnosed to problem and fixed it quickly. Travis was friendly and helpful and answered my questions. I would recommend them to anyone.

    When I called to request service they were able to send someone out that same day. When Edgar arrived he was polite and courteous. He explained what he was going to complete the diagnostics first. He then explained what needed to be done and made sure I understood. It was very appreciated that he gave me time to decide on my repair because it was going to cost a bit of money. He finished quickly and explained the invoice. Great job!

    Joseph was very knowledgeable and quick to respond. He knew exactly what needed to be fixed and he was right on it. I thank you all for the quick, fast and in a hurry respond you did for my family and I. Especially during this freezing weather. Thank you Joseph for being so kind and understanding. I will use you guys again in the near future!
