Duct Sealing and Leak Repair

In many Addison homes, the HVAC system is located in a hot attic where duct leaks allow 120°F+ air to mix with your conditioned air before it reaches the upstairs vents. This 'stack effect' is worsened by duct leakage, as the coldest air often escapes at the highest pressure points near the furnace. Professional sealing ensures that the air reaching your upstairs bedrooms is as cold as the air on the ground floor.

Most Addison homes built since the 1980s utilize flexible 'flex' ductwork, which is cost-effective but prone to sagging, kinking, and tears from attic traffic or pests. Older homes in the area may have galvanized metal ducts, which are more durable but often have leaks at every joint and seam. Regardless of the material, all duct types in North Texas eventually require resealing as the original tapes and sealants degrade over time due to extreme attic heat.

Yes, local wildlife such as squirrels, raccoons, and rodents are a common cause of duct damage in Addison attics, often tearing through the outer insulation of flex ducts to build nests. These punctures create massive air leaks and can introduce animal dander and odors directly into your home's air supply. If you have recently had a pest issue, a thorough duct inspection and repair are essential to restore your system's efficiency and hygiene.
