Replacing old, drafty windows is one of the smartest home improvement investments you can make in Central Texas. During our long, scorching summer heatwaves, up to 30% of a home's cooling energy is lost through inefficient windows. Upgrading to modern, energy-efficient windows can slash your Austin Energy cooling bills, reduce strain on your AC system, and quiet the noise of busy city streets.
However, window shopping in Texas is unique. Because our primary climate challenge is extreme heat rather than freezing cold, the type of glass and coatings you choose is critical.
This guide details the best window replacement services in Austin, TX, local pricing, Austin Energy rebates, and how to choose the right glass for the Texas sun.
The Key to Texas Windows: Low SHGC
When evaluating windows in Austin, the most important metric is SHGC (Solar Heat Gain Coefficient). This rating measures how much solar radiation passes through the window, heating your home.
- Northern Climate Rule: High SHGC is preferred to let winter sun warm the home.
- Austin, Texas Rule: You need a very LOW SHGC (typically 0.22 or lower).
- Low-E Glass is Essential: Look for double-pane windows treated with advanced Low-Emissivity (Low-E) coatings, such as Cardinal LoE-366. This microscopically thin metallic layer reflects infrared heat away from your home while allowing visible light to pass through, preventing your home from acting like a greenhouse.
