"My experience with Standard Renewable Energy was fantastic in every way. I got an amazing insulation job for the price and now my house is so warm! Everyone I dealt with from SRE (from the salesperson to the technician) was so nice and professional. I have already told all my friends and neighbors about this company...outstanding customer service!!!"

Forrest was extremely responsive. I called and he was able to come by, I believe, the next day to an energy audit to determine why my electric bill was outrageous and the temperature varied throughout the house. Right away he determined there was virtually no insulation in the attic (easier said than done considering the dark,  3 ft crawl space filled with giant metal ducts) except what was left from the original install in 1975. I was able to schedule to have the work done in about 5 days. I'm not sure if the price was good or not but I really liked Forrest and he was available to get the work done ASAP...that made it the right price!  He and his crew arrived when they said they would, blew in the insulation, mended ducts, expelled all the critters in the attic, and replaced the broken booster fan blocking the air going to the opposite end of the house.

I also texted Forrest Friday with concerns that there was hot air coming out of the vent when the AC wasn't on, he said he could be there the next day to check it out. He showed up when he said he would, determined that coincidently, I walked under the vent right when the AC turned on and all the hot air was being pushed from the duct.  There was no issues other than my bad timing.

I will continue to use this company for everything and anything they can provide that I need in the future.

"Easily the best experience I have had with any contractor in this area after one year of maintaining a 100 year old home! They were punctual and accommodating and went out of their way to ensure complete, quality work at fair prices. I was ready to do a much larger project but found it was unnecessary with their assistance. Highly recommend Insulation Works for any home energy needs."

"From start to completion everything for the initial quote, to showing up on time, to completing the job quickly and cleaning up was absolute professionalism. Kent , the owner, was great and everything he told me was correct. I have waited to post my evalution because I wanted to receive my first utility bill after completion. My utility bills in the summer were ranging from $250-$300 a month. I have a 2267 square foot home with a pool. My first bill since my new installation was $200.00, a wonderful drop from last year. The pool uses a lot of energy. Before, my garage was incredibly hot in the summer and I can really tell the difference. I leave my thermostat on 78 and it is actually cold at night. I highly recommend them.

"I was totally satisfied and impressed with the Annual Maintenance tune-up of our HVAC system. Their technician, Mr. Javier Vasquez exemplified the highest standard in customer service and professionalism. He made us aware his main task was to complete the annual HVAC system service, but offered, up front, to let us take him around to other areas of our home and show him any other concerns we might have, i.e., electrical, plumbing, etc. We took him around and he made notes of our concerns, explaining that he would notate those on the invoice so that we and they had record of it, and, when we were ready, we could call them for needed services, at our convenience. And, to top it off, Mr. Vasquez took time to help me reboot my Smart Home Ap. My hat's off to Mr. Javier Vasquez and to the Jon Wayne Team."

"My husband worked primarily with Laine Houston during the entire process.  Laine was professional and spent a great deal of time working out the plan for our home.  He personally designed the new duct work for better air flow which enabled us to receive a total of $3.800 in rebates from CPS Energy.  Needless to say we are extremely happy with the new HVAC unit and the service Tasco provided.

"This is the 4th unit we have replaced in our 35 year marriage. We both believe Henry Rodriguez is one of the most knowledgeable heating and air conditioning person we have ever met. He is the owner of the company and takes great pride in his work and the work done by his employees.
Our duct work was improperly installed and  had lots of holes in the ducts. Henry went over and beyond my husbands expectation. When they encountered something that was done improperly, he fixed it at no additional charge to us. He even found copper pipe that was improperly sized and replaced it.
His crew were very clean cut, professional, polite men.
We would absolutely hire them again and recommend that anyone in need of heating or air conditioning work call Texas Air for a free consultation.
This company is way beyond a 10.....we would give them a 20.

"I was considering 3 companies to do the work. They provided the best deal. The installation went very smoothly; finished in a day. Very happy with the process to that point. Had some problems with some logistics afterward. The papers weren't processed properly to iniitally run the solar panels (it took 2 months till we figured out the electric company hadn't 'turned on' the panels). There was also some problems with the paperwork for the tax rebates that slowed things down. I talked to the owner Mark, who was very sorry for the problems and offered a small refund, even though we don't really know what happened. He wanted to be sure I was a happy customer, which I am. I was impressed by his professionalism. However, I'm still not seeing the savings that I was told. I've had my house energy audited, installed Nest thermostats, and still not seeing a major decrease in my KWh usage. I can only assume that we are having a hotter season than last year; hoping to realize savings next year.

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.
