Leaky ducts, especially near water, raise humidity and make your home feel damp and uncomfortable.

Leaky air ducts are a common issue that can raise indoor humidity and increase energy costs—especially in homes near the water. When ducts leak, cooled air escapes into attics or walls, and warm, moist air enters your home, making it feel damp and uncomfortable.

In coastal areas, even small duct leaks can lead to big problems like mold growth, damage to furniture, and extra strain on your A/C system. This not only affects comfort but also drives up your energy bills.

At Annaville Air Conditioning, we use tools like the Minneapolis Duct Blaster to locate hidden leaks and measure air loss. Most homes we test show significant leakage, costing homeowners money and comfort.

Sealing or replacing leaky ducts can reduce humidity, improve indoor air quality, and help your system run more efficiently. It’s a smart investment that can make a noticeable difference in how your home feels.

From minor repairs to full replacements, Annaville A/C has your air duct needs covered.

The City of Corpus Christi is enforcing the code, stating that all new homes built today have their ducts tested by an independent 3rd party tester. We are learning that homes with tight, non-leaking ducts require much lower capacity air conditioning to stay comfortable.

This saves the consumer money because they can purchase a smaller A/C and save thousands of dollars in wasted energy over the lifespan of the home. It is also good for the environment to not waste electricity and fuel required to heat and cool our homes and business. We recommend a duct pressure test and visual inspection for all homes that have ducts in an unconditioned attic at least once every 5 years. Ducts located in these extreme conditions can test OK for now, but 5 years from now may develop serious leakage.

In addition to offering “duct pressure testing” to residents of Corpus Christi we extend this service to residents of Robstown, Sinton, Odem, Banquette, Bishop, Orange Grove, Driscoll, Sandia, Mathis, San Patricio.
