"I will NEVER use ARS of Virginia again! ARS failed sales & installation. During sales pitch on 12/17, I was told install team would cover floors & anything else. 12/18- During HVAC installation, install team drilled into the brick wall to run the pvc piping outside. They did not cover anything so the brick dust went everywhere! They also failed to seal around the pvc piping hole indoors so cold air was seeping in. Lastly, they spilled pvc primer that is not removable all over my white floors. 12/21- Called ARS b/c house was filled w/ a plastic burning smell. ARS sent tech who said he could not smell anything due to his nasal congestion. He explained that new HVAC may need to ?air out?. 12/23- Heat stopped working in middle of night. Called ARS tech discovered that the air handler burned out b/c it was improperly installed. Plastic condensation tubing was installed outside so it froze & led to heat failure. That explained burning plastic smell b/c air handler was working overtime."

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!"

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

"Needed to replace a 25+ year old HVAC system in the coldest months of the year, so I contacted Advanced Environment Solutions for a bid. I worked with Tammy at AES to schedule the inspection, follow-up, etc. - a fantastic employee. Courteous, professional, and really knows her stuff when it comes to HVAC. Unfortunately, I live in a condo with a tricky indoor/outdoor HVAC set-up that ended up requiring a fairly specific indoor unit that AES did not offer, so I had to go with another company. Still I felt compelled to leave a review for AES and Tammy to highlight their professionalism and service-oriented approach. WiIll absolutely consider AES for future projects."

FAQs for tankless water heater installation projects in Winchester, VA

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.
