What is Air Duct Sealing?

At Reliable Air, we often get questions from San Marcos homeowners about air duct sealing and its benefits. Air duct sealing is a professional process that involves locating and sealing any leaks, gaps, or holes in your home’s ductwork. This ensures that your HVAC system operates efficiently, keeping your home comfortable and reducing energy waste.

Over time, ducts can develop small cracks or separations due to wear, settling, or even construction issues. These leaks allow conditioned air to escape before it reaches the rooms in your home, forcing your HVAC system to work harder to maintain the desired temperature. 

Signs you Need Duct Sealing

Here are some signs that you need air duct sealing in your San Marcos home: 

  • Higher-than-Normal Energy Bills: Leaks in the ducts cause conditioned air to escape, forcing your HVAC system to work harder to maintain temperatures, which significantly increases energy consumption and costs.
  • Uneven Temperatures in the Home: When conditioned air escapes through leaks, it doesn’t reach all rooms evenly, creating hot or cold spots and making some areas of your home uncomfortable.
  • Rooms Feel Stuffy or Humid: Air leaks prevent the proper circulation of cool or warm air, leading to inadequate ventilation, causing some rooms to feel more humid or less comfortable.
  • Poor Indoor Air Quality: Gaps in ductwork can pull in dust, allergens, and contaminants from areas like attics or crawl spaces, circulating them through your home.
