Services
Radiant Barrier
Radiant barrier insulation reflects up to 97% of attic heat, reducing cooling costs by up to 35% in warm climates. Installed under roofing, it prevents heat transfer into living spaces. Homeowners benefit from lower energy bills and improved HVAC efficiency.
Window Replacement
Double-pane window installations enhance thermal efficiency and reduce noise pollution. Our ENERGY STAR-rated windows lower energy bills and increase home value. Custom options include double-hung, casement, and sliding styles.
Attic Insulation
Blown-in fiberglass and radiant barrier combinations improve R-value and temperature regulation. Proper insulation reduces energy consumption and prevents mold growth from moisture buildup. Ideal for Texas climates.
Water Softeners
Salt-based systems remove calcium and magnesium to prevent scale buildup. Softened water extends appliance life and improves soap efficiency. Our NSF-certified models use 75% less salt than traditional systems.
Attic Ventilation
Soffit and ridge vent systems reduce attic temperatures by 70F, preventing roof damage and mold. Proper airflow extends shingle lifespan and maintains indoor air quality. Combines with insulation for optimal efficiency.

Jymi came out, where other companies didn't, and provided with knowledgeable information that could've cost us thousands from someone trying to rip us off. I am thankful for his honestly, promptness, and knowledge. Thank you Green Energy!

Green Energy gets an A+ from my husband and I. From beginning to end they were professional and honest when answering any and all questions. You can tell you're doing business with a family that values and takes pride in all they do. We had radiant barrier and windows installed. I am even impressed with the finance company Green Energy intrust to take care of their customers. Overall, I would highly recommend them to anyone.

What a great experience! We just replaced all of the windows and patio doors on our 35 year old home in Sonterra. Richard came out to give us a bid and demonstrate his product. We were expecting a much higher price for such high quality windows. We were so impressed that we signed up on the spot. Richard and his entire crew were absolutely wonderful to work with. His daughter Aimee runs the office and she made sure to keep us informed every step of the way. The installer's, Dave, his daughter, Carrie Ann and Dave's brother Jim, were so diligent ... showed up on time and always left the work space
