"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."

"Jimmy Gusky HVAC is truly as good as it gets. One of our AC units went down and through the warranty company found our way to Jimmy Gusky himself. Although out of their territory, Jimmy was willing to make the extra trip to diagnose the problem. He was very responsive to get our initial service call scheduled and determined the unit needed to be replaced, and we all know these units usually decide to break down only when pushed to the limit in the hottest summer months and we need AC the most. He did the legwork to get the warranty company to honor the recommendation and as you can see from the attached photo put in a much more substantial unit that is doing a fabulous job cooling the home. Add to that he actually had the unit and scheduled the install even before the warranty company approved the swap out. I that isn't one of the greatest examples of outstanding customer service and going above and beyond to exceed expectations, I don't know what is. Big thanks to Jimmy and team for their commitment to excellence!"

"Being a MVP customer was time for Heating/Cooling safety inspections. Kevin Stanley was the HVAC Service Tech assigned to the job. He went over a few issues on our older unit he found during his inspection. I never felt pressured to have the work done and so glad he resolved them on the same day. He definitely went out of his way doing a great job. He explained everything to me that he was doing and also answering all the questions I had. The price was reasonable. Will definitely call Appleton Campbell when needing home repairs, this is our 3rd project they’ve taken care of. Thanks again"

"SwiftPro was excellent. When our hot water heater went out (at nearly 20 years old, we were neither upset nor surprised!) we reached out to a few places but SwiftPro was the most responsive and had the price was fair. Zabi, the service technician was fantastic. I can’t say enough good things about him. He was prompt, provided excellent communication, took meticulous care with the work and work space, and was just a great person to talk to. The install went great and there was no aggressive sales tactics or upselling. Just a genuine cut and dry hot water heater removal and install experience. I highly recommend SwiftPro. Thanks Zabi!"

"Had a surprise when workmen showed up unannounced the day after I signed the contract. Once we rescheduled the installation date and time, things went very smoothly. The installation of the furnace, AC, and hot water heater took less than a day. I'm very happy with the results."

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"Our water heater stopped working overnight and we contacted Done Rite Services in the early morning to diagnose the issue. They immediately responded and said someone would be out to the house later that afternoon/evening. Edgardo called later in the day and asked if he could come out earlier. Upon arrival he took the proper COVID precautions and wore and mask and also ensured he covered his shoes to protect our floors. After diagnosing the problem and considering the age of the water heater and the overall installation not being up to code, we decided a replacement was needed. Edgardo thoroughly and patiently described the options for a replacement water heater and quickly checked if they were result in stock. After deciding on a model, he was able to schedule an installation in about 24 hours! During the replacement, Edgardo and Ethan were very thoughtful, respectful, and thorough, ensuring they took care to install the water heater correctly and to code. They were both wonderful to work with, very professional, and caring to make sure the installation was correct. We will definitely consider them for future plumbing work!!!"

FAQs for water heater repair or service projects in Sterling, 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.
