"Needed to repair or replace my tankless electric water heater. Many other companies refused to even take a look. Worked with Andy, had to get mine replaced but did it quick and very professional."

"During an intense heatwave, Moises provided exceptional emergency service for our aging commercial HVAC units at the church, ensuring they kept running through the hottest days of the summer. Their prompt response, expert repairs, dedication to quality, and fair pricing were truly impressive. For reliable and top-tier HVAC services, Moises is a standout choice. I highly recommend Tyler, Moises, and the entire team at SwiftPro for all your commercial or residential HVAC needs!"

"I can't say enough about DB's Plumbing. I called in the morning, had a return call within hours and they were at my house that night. 24 hours later, the new hot water heater was installed! Price beat all others. Duncan was professional and knew exactly what he was doing. DB Plumbing is now my GO TO PLUMBER!"

"Excellent service. We have had both Kevin and John out to service one of our units. Both have been extremely professional, helpful and fair. Kat in the office is a great help, too. I had forgotten to respond to her message before the office closed (something came up in the family) and she called me back to offer to help. Most people on a Friday night are rushing to get out and won't take the extra time to follow-up like that. She also helped a friend of mine (not an Angie's List subscriber or she would leave a review) arrange emergency service and she and John spent 15 minutes on the phone with her answering her questions. Very impressed by this considering she was not a client (yet) at the time. THAT is how you run a business. A lot of companies out there could learn from them. <br />"

"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"I had to replace a water heater quickly. Gave me a competitive quote with a water heater with desirable specs within a day and scheduled me the day after. Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"Oullette's team was able to complete the installation in two days and haul away the old units. The new system is much more effective with consistent temperatures throughout our home. As well, it is much more efficient with demonstrably lower electric bills. We wholeheartedly recommend this company."

FAQs for water heater repair or service projects in Ashburn, VA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
