Cheaper Bills, More Comfort, Real Results.
Texas Home & Commercial Energy Audits
Do you find your energy bills soaring in the hot Texas summers or the cold winters? Is your air conditioner unable to heat or cool your home? Do certain rooms always feel warmer or cooler than the rest?
GBES has some answers to those questions.
Our Home Energy Audits (HEP) for residential properties and Total Energy Performance (TEP) audits for commercial buildings help find out precisely where energy is being wasted — and how to rectify it. Such broad energy-efficiency inspections are designed to help homeowners and businesspeople minimize utility bills, enhance indoor comfort, and improve a building’s thermal envelope.
Who Should Get a Home Energy Audit?
Home Energy Audits help homeowners reduce monthly energy costs and boost their comfort. Older properties benefit the most, but even the newest homes can harbor hidden efficiency problems that can drive up costs. Properties developed more than 30 years ago typically have:
- Poor insulation levels.
- Air leaks in ceilings, walls, and attics.
- Outdated sealing techniques.
- Lack of proper ductwork and HVAC systems.
Your building envelope — the layer of insulation and air sealing that protects your home — is instrumental in your energy performance. Low insulation R-values and air leaks allow energy and conditioned air to escape 24 hours a day, putting strain on your Heating, Ventilation, and Air Conditioning (HVAC) system and increasing your utility bills. GBES also evaluates:
✔ Duct condition and air leakage.
✔ Efficiency and performance of HVAC.
✔ Water heater efficiency.
What is a Home Energy Performance (HEP) Audit?
An HEP Audit is a professional energy efficiency assessment of the home-based energy efficiency system based on a professional examination of air leaks and insulation performance, and building performance from the most modern diagnostic equipment. It pinpoints:
- Where energy is escaping.
- Why some rooms are uncomfortable
- How much efficiency enhancements save you.
These results enable you to smartly upgrade your home to reduce energy costs and increase comfort.
When to Schedule an Energy Audit?
Energy audits are performed year-round, and they can be done any time, but are especially worthwhile in the following situations:
- Your energy bills keep increasing.
- Your home feels drafty or cooled unevenly.
- You’re in the process of renovating or upgrading your insulation.
- Your HVAC runs all the time.
How GBES Performs Professional Energy Audits.
Blower door testing — Finds hidden air leaks.
A blower door test is one of the best ways to determine energy loss in a home. We place a high-powered fan inside an exterior doorway to depressurize the house by 50 Pascals—the same pressure as would be expected with strong outside wind. This forces outside air into the building through leaks in the building envelope. With a precision manometer, we measure:
- Air infiltration rates.
- Cubic Feet Per Minute (CFM).
- Air Changes Per Hour (ACH).
This shows just how much air leakage your house has.
Why Choose GBES for Energy Audits?
✔ Residential & commercial energy audit experts.
✔ Blower door testing & infrared thermal inspections.
✔ Actionable reports with real savings solutions.
✔ Improved comfort & indoor air quality.
✔ Proven energy efficiency results.
Infrared Thermal Imaging – See Energy Waste in Real Time.
In addition to blower door testing, GBES uses a high-resolution FLIR infrared thermal camera to detect temperature discrepancies as small as 0.1°F, allowing us to:
- Identify air leak sources.
- Find missing or damaged insulation.
- Look for hidden moisture or thermal weak points.
You’ll actually have visibility into where you are losing energy in your home — something the naked eye can’t see.
