Question 3

What is the best window for Houston heat?

Accepted Answer

For Houston's climate, the best replacement windows feature Low-E glass coatings with argon gas fill, a Solar Heat Gain Coefficient (SHGC) of 0.25 or lower, and ENERGY STAR South-Central certification. Vinyl frames are the most practical choice — they handle Houston humidity and heat without rotting or warping.

Yes. The IRS Section 25C Energy Efficient Home Improvement Credit allows homeowners to claim 30% of the cost of qualifying replacement windows, up to $600 per year through 2032. Windows must meet ENERGY STAR South-Central requirements (U-factor ≤ 0.40, SHGC ≤ 0.25).
