We fix no-heat, error codes, and flow problems fast so your hot water gets back to normal.
When your tankless water heater stops working the way it should, you need fast help from a plumber who knows these systems inside and out. At Byron Plumbing Services, we provide professional tankless water heater repair for homeowners in Sugar Land, TX and nearby areas. With nearly 20 years of hands-on plumbing experience, we know how to find the real cause of the problem, explain it clearly, and make the right repair to get your hot water back.
Tankless units are efficient and reliable, but they are more complex than standard tank water heaters. These systems rely on sensors, burners or heating elements, venting, gas or electrical connections, water flow, and control boards all working together. When one part is off, you may notice no hot water, water that turns cold too fast, low water temperature, error codes, ignition failure, strange noises, reduced water pressure, leaks, or mineral buildup. We repair both gas tankless water heaters and electric tankless water heaters, and we work on many common makes and models.
We start with a full inspection and system diagnosis. Instead of guessing, we check the unit carefully so we can identify the source of the issue. Our repair service may include:
Once we know what is wrong, we explain the repair in simple terms and let you know what to expect. Our goal is to restore safe, steady hot water with a repair that lasts.
Tankless water heaters can show symptoms in different ways. Some issues are easy to spot, while others need a trained plumber to diagnose properly. We regularly help customers with problems such as:
In many cases, these problems are caused by scale buildup, dirty filters, worn parts, failed sensors, blocked venting, gas supply issues, or lack of routine maintenance. Because tankless systems heat water on demand, even a small issue can affect performance quickly. That is why timely repair matters.
Putting off repair can lead to bigger problems and more costly damage. A struggling unit may use more energy, deliver poor performance, or wear down important parts faster. In some cases, leaks can damage surrounding walls or flooring. Gas and venting issues can also create safety concerns if not handled correctly. Our team is licensed and insured, and we take every repair seriously. We focus on safe operation, code-conscious work, and dependable results.
Fast repair also helps protect the efficiency that made you choose a tankless water heater in the first place. A properly working unit gives you reliable hot water, saves space, and can help lower energy use compared to older storage tank systems. When problems start, professional service helps your system perform the way it should.
If you notice any of the following, it is a good time to schedule service:
Calling early can often prevent a complete breakdown and help avoid a more expensive repair later.

"I have been using Byron Plumbing Services, inc. for approximately 7 years or more. Not sure how I got connected with them but they have all my residential plumbing business since their first visit. They have performed routine drain clogs to complete under slab excavations for pipe replacement. Recently on a call to unclog a drain, they found the drain line in one of my rent properties was still connected to the old septic system via a camera and radio tracking device while another drain connected to city sewer. A few days later the work was completed. The work consisted of digging up about 100' of my front yard and replacing the entire tie into the city sewer. I paid them in full, then later went and looked at the work (not normal but I do this for them). You would expect a mess of dirt and dead grass but they carefully cut out the sod, did the work and put the sod back and watered it so you could hardly tell work was just completed. From call to completion, 4 days. The property was in a rural community 75 miles from Houston. Not sure they travel like this for everyone, but if they know you, they will. The price is reasonable but the quality and care to the homeowner is exceptional. The first time they dug a hole under a house slab to show me the rusted old pipe, they cut stairs into the perfect excavation so I could step down and see what needed to be done to understand the cost, with out having to crawl under the house. I told them I did not need steps anymore and they assured me it was not an extra cost. I do not look forward to plumbing issues, but I also have a go to company that I know is the best so I do not really have any plumbing worries anymore. I text them, they come and fix. I have a lot of experience with contractors as a rental property and home owner. They are exceptional workers and deserve your business."

"Byron was Amazing, Super Friendly, I would Highly Recommend him."
"Byron Plumbing did an excellent job in replacing an old bathroom faucet and the old, leaky plumbing underneath. Byron Jr. did not rush and was meticulous in his work. He even cleaned up the area afterwards! His company truly deserves a five star rating!"

"When a pipe started leaking again that I already had an appointment with Byron to repair at a later date, he rearranged his busy schedule to fit me in within a couple of hours, and did a very thorough job identifying and repairing what turned out not to be just one break area but about 6. It's obvious both Byron and his son take great pride in their work and stand behind it, and I appreciate their responsiveness, thoroughness, and desire to truly perform good service for their customers. My neighbors had recommended them to me, and I totally understand now why they use them for both their house and rental property. Don't call these guys if you're just looking for the quickest, cheapest fix that might create a bigger problem down the road. Instead, these are the people to call if you want quality, guaranteed solutions done right the first time, and to know in the unlikely event they do need to come back to redo something, that there's absolutely no doubt that they will."

"Byron was referred to us through a family friend. Byron is very personable, comfortable to be around, and takes a genuine interest in resolving your problem as if it were his own. So does his son and employees. Half of the battle is finding someone who is knowledgeable, someone you can trust, and who does a quality job at the right price. I highly recommend Byron Plumbing Services. I called Byron initially to clear out a sewage line from a backed-up toilet which required removal of the toilet and use of a snake followed by camera to ensure the line was clean. It was done quickly that day at a great price. I was so impressed with Byron that I had him install all new pex water lines in place of the old, galvanized pipes in our house which is something I needed to do for some time. The work also included a new hot water heater, home water filtration, insulation of all piping, and a couple new electrical outlets for the disposal and dishwasher. The whole job was completed in 3-4 days including obtaining the city permits. They did quality work at a great price. He recommended some great drywall guys too and kept the whole project on schedule. My next project with Byron will be fixing a shower leak and eventually replacement of the underground sewage pipes. I highly recommend Byron Plumbing Services for all your plumbing needs!"
"Delivered fast, professional service with clear communication and expert care! We needed our tankless water heater replaced and Byron Jr was able to get us a quote for two great options. Then our heater went out and he was able to replace it that day! We have used them several times in the past, including at my in-laws house. They are always friendly, knowledgeable, and quick to provide us service. We will definitely keep using them for our plumbing needs and future plumbing projects!!"
"Byron was the first of three plumbers to respond to my call. He fit me in his service calls the next morning, gave a quote, and replaced two corroded valves for a new washing machine installation. He had to remove sheetrock, but replaced the piece with screws and even cleaned the lint and crud from the floor. Byron is a pleasure to talk to, knowledgeable, and to be trusted."
