"Service was completed as expected. Fred came with his son promptly in the morning. He first assessed the issue and made a recommendation for the repair. The work seems to be of good quality. Final price was just as quoted. Fred was very professional and quite personable. Overall I’m happy with their work and excellent customer service. Highly recommended! I will going to Fred for my future plumbing needs."

"Our furnace finally bit the dust after 25 years of faithful service. I had TriState do several small repairs and maintenance on it over the years, and they always did a good job. So, when the last service rep told me it was finally beyond repair, we consulted with Comfort Specialist, Darren, who isn't just a salesman, but previously installed and repaired HVAC systems. He took lots of measurements, inspected the old unit and the runs to the outside and upstairs. He took his time making calculations and offered us several options on a new system. TriState uses Daikin furnaces, which are rated in the top 5 furnaces for dependability and efficiency. The price, I thought, compared to my two other neighbors, who also recently purchased new systems, was even lower than I thought it going to be. In fact, my neighbors paid more (by thousands) and have a smaller square footage footprint than my house. We've had the unit now for over a month, and so far, it's great. It is a one-zone system, yet the upstairs will only vary by one or two degrees. This is much better than the old unit. We're hoping this small variance in temperature will also apply when the AC is on in the summer. The installers were very professional, arrived on time and completed the work in a timely manner. I would definitely use TriState again, and will rely on them whenever I need service."

"My Remedy Plumber arrived on time and didn’t really charge me for his service because he stated what he needed to do may not fix my problem because I needed a new faucet which he did not have. Water was running from both the tub’s faucet and the shower head. After pulling off the faucet and making a minor adjustment to a washer within the faucet the problem was "temporary" fixed, the washer was damaged. He stated that a new faucet was needed and that I could call back to have that installed. I thanked him, gave him a small thank you gift, and he was on his way. I was thankful that this plumber had "integrity" and did not try to overcharge me for work that did not fix my problem. I would surly hire this company again!!"

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"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."

"The repair man was a Burmese guy, Joe, and he did an outstanding job changing the anode bar and removing the sediment from my water heater. This should extend the life of the tank. Joe showed up 10 minutes early and finished promptly. He worked hard and had the necessary supplies and tools. He knew what he was doing. I would glad to use Joe again in the future!"

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