"RightNow Plumbing reliably provides competent, scrupulous, trustworthy service. Recently I engaged Andy to service our well-water acid neutralizer tank, because I questioned the reliability of service by another company 13 months earlier. Andy tested our water and found that its pH value was 6.97, which was consistent with previous readings over the past six months when he did other work for us. Because our well-water pH is essentially neutral, Andy explained the acid neutralizer tank is not necessary. He offered two options: 1) remove the tank (thus leaving us with only the water softener tank) or 2) empty it, which option I selected. He also reduced the cost of the service call. Andy’s approach starkly contrasts with the other company that for years took advantage of an unsuspecting customer by charging almost $300 to “service” the tank and unnecessarily adding expensive calcite. For competent, scrupulous, trustworthy service, call RightNow Plumbing. Posted May 14, 2025"

The AES Team has 15 employees with 8 trucks to provide quality Heating/Cooling & Plumbing services 24/7. The AES team is committed to hiring and retaining some of the most qualified technicians in the area, with a minimum of 10 years experience. We make training a priority for our technicians and their helpers. We keep the vans stocked with many replacement parts to get you back up and running during our first visit.

"Unlike another provider whom I did not hire, arrived exactly on time for the site survey. Worksite in Spotslyvania, VA, and I live in Arnold, MD, so about a 2 hr drive for me. Had a firm proposal within 24 hours, install was scheduled that day. On install day, technician arrived exactly on time, following all COVID precautions. Work was completed in slightly less time than he projected. Quality of the work was first rate. Left the house and area surrounding the work - install new heat pump outdoor unit and indoor unit in attic - cleaner than when they started. All three technicians who worked the project were just terrific. Friendly, respectful of the property, very informative. They made sure I understood the improvements they'd made to the ancillary portions of the system (e.g. drain pan and condensate drains from the attic), and worked through the new thermostat details as well. Everyone I'm came in contact with from Advanced Environment Solutions was professional, responsive and were truly interested in making sure I got what I needed. There is one other reason why I would implicitly trust these folks. When the president of the company (John Smith) came out to do the estimate, he carefully explained the various levels of the systems that would match the house. He did NOT try to "upsell" me on a system that was more expensive than the property warranted. He carefully explained the technical benefits of proposed upgrades to the drain systems and the need to install a path from the attic entrance to the interior unit for safety (agreed immediately). I'm a licensed mechanical engineer, and his explanations were complete and accurate. In sum, a highly professional company, exacting standards of technical performance, they listen to their customers and their integrity is unmatched."

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

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
