"Very fast and professional service! I received a text just 5–7 minutes after submitting my request on Angi. Kati explained the process and quickly scheduled an appointment. Johny arrived within an hour, inspected the old heater, and although he suspected it needed replacement, he still contacted the manufacturer to explore repair options. The repair was estimated at $300–$400, but we chose to replace the unit instead. The replacement was completed within 5 hours of the initial visit. Kati and Johny were patient and informative, walking me through payment options and explaining the differences between heater models. Overall, excellent service and quick turnaround. I wish it had been a bit more affordable, but I couldn’t get quotes from other providers without a home visit. Highly recommended!"

Advanced Environment Solutions, Inc., is dedicated to providing our customers with the best quality and craftsmanship. We are here to build relationships with our customers and communities and to provide our employees with a great place to work. Advanced Environment Solutions, Inc., is a leader in providing our customers with the highest quality products and craftsmanship in an honest, efficient, and professional way. Our pledge is to create successful relationships with our customers, employees and community by building trust, treating every project with the utmost integrity and exceeding expectations.

"From the moment I received a call from Tammy at Advanced Environment Solutions Inc. (AES), I knew I was dealing with a company that stands out from the rest. We had been shopping around for HVAC replacement quotes, and to our surprise, AES offered an over-the-phone estimate that was a staggering $7,000 less than any other quote we had received. This wasn't just a promise; it was a reality that they delivered on with professionalism and integrity. The process was seamless. After a quick confirmation visit by their technician to verify our unit size, everything was set in motion. On the day of installation, despite the sweltering heat, AES's teams worked with remarkable efficiency. One team expertly removed our old unit, and almost immediately, another arrived with the new one. The entire replacement was completed in a single day, leaving us both amazed and immensely grateful. The staff at AES were not only professional but also incredibly courteous and knowledgeable. They explained each step of the process, ensuring we understood everything. The quality of the new HVAC unit they installed surpasses any expectations we had, offering superior performance and energy efficiency. What's most puzzling and impressive is how AES manages to undercut competitors by such a significant margin while providing top-notch service and quality. This is a testament to their business model, which prioritizes customer satisfaction and ethical pricing. We highly recommend Advanced Environment Solutions Inc. to anyone in need of HVAC services. Their commitment to excellence, combined with unbeatable pricing, makes them the go-to choice. Contact AES, and like us, you'll discover why they are simply awesome!"

KBA Kitchen and Bath: Transforming Homes with Excellence for Over 25 Years. Proudly Serving Fairfax County and Fauquier County.

"We would like to say thank you to KBA Kitchen & Bath Design & Build for a great job remodeling our two upstairs bathrooms. The two bathrooms were completely renovated in 5 weeks, but it could have been finished even sooner if we hadn’t selected a premium option for our shower glass enclosure. The entire project was started and finished between January 21, 2025 until February 28, 2025, which included the crew working two Saturdays, which shows their dedication in getting the job done. We were very impressed with KBA over the entire project! Specifically, we were impressed at how smooth and efficient the entire process was. It was seamless – from the initial consultation to the execution of the job. The designer, Anna, was very thorough and helpful in sketching the designs of new bathrooms and offering advice on recommended materials for the bathroom, to include going above and beyond in helping us choose just the right paint colors to perfectly blend with our newly installed bathroom accessories. Anna and Ervin both made after hour visits to provide their insight on color schemes and where bathroom accessories should be installed and look best. The lead project manager, Ervin, was always there to answer our questions, and he went out of his way to always ensure we were happy customers! Ervin also visited on many occasions to give us updates on project progress and keeping his crew updated on any changes. The installation team always showed up on time, left the work area clean, and went above and beyond to make our design a reality. Anna, Ervin and the crew were always very friendly, professional, and helpful throughout this project. We couldn’t be happier with the outcome as we absolutely love our bathrooms! We highly recommend choosing KBA for your next home project!"

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
