How New Energy-Efficient Windows Can Lower Your Fall Utility Bills in Central Texas


Rising fall and winter bills hit Austin, Round Rock, Cedar Park, Pflugerville, and Georgetown every year. Cooler nights arrive, drafts show up, and HVAC runtimes creep higher. Here is the good news. Upgrading to modern, energy-efficient windows and tuning your exterior systems can cut waste and steady indoor temps.

JP Exteriors is your local contractor for energy-smart upgrades across Central Texas: window replacement, siding, roofing, gutters, decks, patio covers, and exterior finishes. We keep the process clear and pressure-free.

Why energy-efficient windows matter

  • Real savings. Replacing poor-performing windows with ENERGY STAR® certified models can reduce household energy costs by about 12% on average. Savings vary by region and by what you are upgrading from.

  • Know the numbers. Look for a low U-factor for better insulation and an SHGC that fits our warm climate to limit solar heat gain. The U.S. Department of Energy explains both ratings and why they matter.

  • Pick for our climate. ENERGY STAR climate guidance helps you select the right ratings for Central Texas.

We match products to the home and budget, then verify ratings.

  • Series 2000, Series 4000, Elite

    • ENERGY STAR options across the board.

    • Low-E coated, double-pane standard with triple-pane available on Elite. Low-E glass reduces unwanted heat gain while keeping winter heat indoors.

    • Frames offered in vinyl, composite, and fiberglass to balance cost, strength, and expansion in heat.

Smart exterior upgrades that support lower bills

Siding – James Hardie fiber cement

  • Built for Texas sun and storms. Stable panels help preserve weather-tight wall assemblies when paired with proper housewrap and insulation.

  • Low maintenance and strong curb appeal.

Roofing – cool roof choices

  • Light, reflective shingles or metal panels can lower roof temperatures and ease cooling loads. DOE and ENERGY STAR describe how “cool roofs” reflect more sunlight and absorb less heat.

Gutters

  • Seamless systems protect fascia, walls, and foundations so insulation and sheathing stay dry and effective. DOE’s building guides stress moving water away from the house.

Decks and patio covers

  • Shade reduces direct solar gain at large glass areas. DOE notes window shading can significantly cut heat gain, with awnings reducing summer solar gain up to 65% on south-facing and 77% on west-facing windows.

Paint and exterior finishes

  • UV-resistant coatings protect substrates and sealants, helping windows and trim maintain performance over time.

Main benefits you feel this fall

  • Better insulation at the glass. Lower U-factor limits heat loss on cool nights.

  • Fewer drafts and leaks. Tight frames and pro installation reduce infiltration.

  • Low-E stability. Coatings reflect infrared heat while admitting daylight, which helps hold steady indoor temperatures.

  • Lower HVAC strain. Shorter runtimes can extend equipment life.

  • Curb appeal and resale. Cleaner sightlines and fresh exteriors help value and show better.

Why act in the fall

  • Crews can work quickly before winter fronts bring wind and rain.

  • Cooler weather reveals weak seals and fogged units. Replacing now prevents comfort complaints in January.

  • Supply lines and lead times are favorable before peak winter service calls.
