"My experience was literally a nightmare. We have been out of AC since 7/15 and just got it back on 8/18 no thanks to Jason. I had to hire someone else. When it first went out he came over and cleaned out the drains but then we still continued to have the same issue the next day. When I texted him there was no response or an eta when he could come two days went buy and nothing. Finally he sent his other worker to come but I had already called a different company. They diagnosed the issue and Jason ordered the part because it was still under warranty. Took the weekend for the part to come in. He sent Scott to put it in and it still didn’t solve the issue. Jason didn’t even look at it but based on what Scott told him he ordered a new circuit board. Told me he was out of town when I asked him about the part and said it was going to be back ordered two weeks. Waited two weeks reached out Jason and the part was delayed another three days. Then it took him an extra three days to actually come install it even though he kept promising me tomorrow. Tomorrow. Came finally installed the part then said it was the thermostat so I bought a new thermostat. That didn’t work so he said he had to call tech support the next day. Said that tech support said it was my nest and he would come by the next day to install my old thermostat. He didn’t show up for three more days and his response was. “I’ve been in an attic all day. “ or he simply wouldn’t respond. Sent Scott over to install thermostat and it still didn’t work so they took apart and left my machine we wires everywhere and said it needed another part and would be back in the morning. We told him don’t bother coming back. I hired someone else who stayed all day until the job was done. Turns out it was a sensor and had he actually not done a half a**job he would have been able to diagnosis it. The new guy said they messes up things so bad it took him twice the amount of time. I have used Jason for years and will never call him again."

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

FAQs for energy efficiency auditing projects in Gonzales, TX
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
