Leaky ducts can lead to wasted energy and uneven heating or cooling. This post explains why sealing ducts matters and how to do it.

How Duct Leaks Impact Energy Use

Air leaks in ducts cause conditioned air to escape before reaching living spaces.

This increases system workload, energy usage, and utility bills.

Signs of Leaky Ducts

Noticeable airflow issues, hot/cold spots, or higher than normal bills may indicate leaks.

Visual inspections and professional testing can locate leaks accurately.

Sealing Methods

Mastic sealant and metal tape are common materials used to close duct gaps.

Proper sealing requires cleaning the duct surface and applying sealant carefully for lasting results.

Benefits of Duct Sealing

Improved airflow and system efficiency leads to lower energy costs and enhanced comfort.

Sealing also keeps dust and allergens out of your ducts, improving indoor air quality.
