"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."

"We had a problem with a drain from a window well that would result in continuous flooding in our basement. We were finally able to fix the problem with the drain and hopefully prevent further flooding. So we contacted two businesses about mold remediation and removal of the damaged drywall and paneling. The first company, provided a good estimate but they were not as professional or reliable as we wanted. After searching online we were able to located American Home Services and then used Angie's List and saw they had great reviews. I immediately called them about receiving a free estimate and they offered to be out at my house the next day to give us an estimate. The President of the company was the person who came out to give us our estimate. He was able to explain everything that would need to be done a reasonable time frame (2 days). I received the completed estimate within 24 hours and scheduled the appointment shortly there after. American Home Services responded on time and placed plastic down in the hallway that leads to our basement to prevent any damage to our floors. My wife and I then waited as they worked for the day and after they completed the days work, they then showed us the basement and what they completed. Overnight they left a dehumidifier and other equipment to complete the work. The next day they came back and hand cleaned any spots that weren't completely cleaned within the first day's work. After they were done, I was then shown the basement and the work that was done. I then received a receipt for the services and a print out of all the work/chemicals that were used in the basement during the repair. American Home Services then provided us with a warranty to come back and fix any problems within the first year. Overall American Home Services is a great business that is willing to work with their clients and make sure that their needs and concerns are met.

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."

"Excellent company! My water heater stopped working on New Years Eve. Unfortunately, the water heater is behind my HVAC, so they had to remove the HVAC, remove the old water heater, install the new heater, and replace the HVAC. They did a perfect job. They also replaced the freon in my HVAC, because the prior repairmen didn’t add freon. In addition, they fixed the jets in my spa. The team arrived on time, displayed professionalism, and cleaned up afterwards. I would definitely hire them again."

"The valve started spraying water all inside the cabinet last night around 9 pm. Called Magnolia in the morning and was given an appointment from 2-4. Dispatch called me at 3:30 to tell me that the technician was running very late and it would be at least another hour. I was given the choice to wait or to reschedule. I had waited this long so I choose to wait. The tech arrived approximately around 7 p.m. The whole job took 30 minutes, only about 10 of which were actually replacing the valve. So given the time I feel the price was extreme. I've used Magnolia in the past and they have always been expensive, but this seemed a little higher than normal. I had waited this long, though, so I wasn't going to try and get another plumber and miss more work so I let them perform the switch. I would use them again if I had an emergency, since they have always been responsive, but I'll think twice given the prices they are charging."

FAQs for water heater repair or service projects in Marbury, MD

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.
