You may already know where some air leakage occurs in your home, such as an under-the-door draft, but you'll need to find the less obvious gaps to properly air seal your home.

For a thorough and accurate measurement of air leakage in your home, hire a qualified technician to conduct an energy audit, particularly a blower door test. A blower door test, which depressurizes a home, can reveal the location of many leaks. A complete energy assessment will also help determine areas in your home that need more insulation.

Without a blower door test, there are ways to find some air leaks yourself.

Maximize your HVAC system's efficiency to stay comfortable during any season.

Controlling your electricity usage and home temperature is easier than you may think.

The electricity usage in your home is affected by the type of windows you have. Learn how you can maximize savings and lessen your energy use. Whether you would like to replace or keep your current windows, you have options.

You can use weatherstripping in your home to seal air leaks around movable building components, such as doors or operable windows. For stationary components, caulk is the appropriate material for filling cracks and gaps.

Before applying weatherstripping in an existing home, you will need to detect the air leaks and assess your ventilation needs to ensure adequate indoor air quality.

Caulk is a flexible material used to seal air leaks through cracks, gaps, or joints less than 1-quarter-inch wide between stationary building components and materials. For components that move -- doors and operable windows, for example -- weatherstripping is the appropriate material.

Before caulking air leaks in an existing home, you will need to detect the leaks and assess your ventilation needs to ensure adequate indoor air quality. In addition to sealing air leaks, caulking can also prevent water damage inside and outside of the home when applied around faucets, ceiling fixtures, water pipes, drains, bathtubs, and other plumbing fixtures.
