At GreenWorks, we know that buying, building, or investing in property is one of the biggest decisions of your life. You deserve absolute peace of mind and confidence in your investment. That’s why we’ve built the nation’s largest privately owned, non-franchise inspection and engineering company—serving with unmatched quality, speed, and care. Unlike most inspectors who only point out problems, GreenWorks provides clear answers, proactive solutions, and cost transparency. Every inspection includes a detailed walkthrough, a comprehensive report with photos, and a free repair estimator so you know exactly what deficiencies mean and how much they will cost to fix. From foundation mapping, plumbing, and HVAC checks to mold, asbestos, radon, and lead testing, our comprehensive services ensure no detail is missed. For homeowners, we are your go-to partner from the first pre-pour on new construction to warranty inspections years later. For realtors, we keep deals moving forward with fast, accurate reports and communication your clients can trust. For commercial investors, we can inspect up to 900 units a day, delivering thorough PCAs, ESAs, and structural plans that keep feasibility studies on schedule. And for builders, we provide engineering-led quality assurance to make sure projects are built right the first time. Founded nearly two decades ago by CEO Harmony Brownwood, GreenWorks was created to raise the bar in an industry that too often settles for the bare minimum. Every inspector completes a rigorous training program—including structural engineering—before serving clients. Our team is backed by licensed engineers, cutting-edge technology, and a full support staff available 365 days a year. When you choose GreenWorks, you’re choosing more than an inspection. You’re choosing a long-term partner committed to safeguarding your property, protecting your investment, and giving you clarity at every step.

"No one ever contacted me about me."

As the nation’s largest full-service exterior home remodeler, we are backed by over 1,000+ Angi Super Service awards and more than one million happy customers. Why? Because we treat each job as an audition. An opportunity to prove ourselves to you. And the results speak for themselves. So make your home all it was meant to be with our unrivaled exterior services. Contact us today for a free, no obligation estimate on replacement windows, roofing, doors, attic insulation, or solar.

"We had an absolutely terrible experience with Power Remodeling. My husband scheduled what was supposed to be a “free estimate” after speaking with a representative named Alfonso. Instead, we ended up with a sales representative (Tara) who turned the visit into an hours-long, extremely pushy sales pitch. She would not take “no” for an answer, ignored my repeated requests to wrap things up, and even told me she would wait at my dining room table until my husband (who had excused himself to take a shower to escape the presentation) came back. I had to firmly ask her to leave multiple times before she finally left — it was incredibly stressful and completely unprofessional. No homeowner should feel pressured or trapped in their own home by a salesperson. This experience has ensured that we will never purchase from this company, and we will warn others to avoid them as well. I am reporting this incident to the BBB, Yelp, Google and other consumer complaint platforms so that other families are aware of these aggressive tactics."

FAQs for home energy audit projects in San Antonio, TX

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
