Double-hung windows in San Angelo, Texas

Two vertically sliding sashes; both the top and bottom sash open. For San Angelo's mixed-age housing stock (54.9% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR South-Central zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.

Short answer

Double-hung windows in San Angelo typically cost $650–$2,945 installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Is a Double-hung window right for a San Angelo home?

Both sashes slide vertically and typically tilt inward for cleaning.

Where it fits:

  • Traditional and historic home styles
  • Rooms facing walkways, porches, or patios (no outward projection)
  • Easy cleaning from inside on upper floors

What to weigh:

  • More potential air-leakage paths than hinged styles at equal quality
  • Half the opening ventilates at any one time

Double-hung windows and San Angelo's climate

San Angelo sits in the ENERGY STAR South-Central zone (IECC zone 3B (warm, dry), Tom Green County), where the priority is a low SHGC (≤ 0.23) to block solar heat.

Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the South-Central zone, prioritize a well-built unit and low-SHGC glass (≤ 0.23) to offset that.

Rebates & incentives in Texas

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

Texas accepted IRA rebate funding but program rollout has lagged; check the State Energy Conservation Office for current status before counting on it. See our San Angelo guide for the full program list.
