Suddenly, our hot water stopped and nothing came out from that side. The cold side worked, though. I called Hot Water Guys at 1:00 on Tuesday and was able to schedule for the next day. Sam arrived and got right to work. He did our annual maintenance and fixed our problem. Before leaving, he made sure that the water heater was connected and working properly on the controller app. It was a bit tricky and Sam had to return to the attic several times, but was patient in helping me with reconnecting the unit to our WiFi. Hot Water Guys installed our unit and we only have them work on it bc we trust their knowledgeable service technicians. We will continue to recommend them. read more

I have used these guys before. I reached out to them at 10pm via website form and asked them to call me in the morning. They called me at 7am. Scheduled a same day appointment for later in the afternoon. The technician, Sam, was running behind from his appointment before my service window but he kept me informed of his timing. As he was about to head to my house, he called me and we talked about the issue I was having. I told him the fault code and sent him a picture via text. He immediately knew what parts were going to be needed to fix the issue. He swung by the office to make sure he had the right parts before arriving at my house. I will for sure be using HWG for all my service needs! Sam is the best tech hands down! read more

Professional crew. Replaced 2 tanks from the attic with a Rinnai with thermal bypass for $5k. Fast and exactly what you need to answer questions you have. Kind of wish some of the office staff on the phone had some more of that due care though. read more

My tankless water heater went out so I called the local "do it all" outfit (plumbing, HVAC, electrical) where I had a service contract. Not only did it take them over 24 hours to get to my house their quote was double what I expected to pay. I thanked the do it all company for their time and called Hot Water Guys around noon. I explained my situation to the lady who answered my call and asked if she could give me a rough estimate over the phone. She quickly provided an estimate that was 35% less than the do it all outfit. So naturally, I asked to get on their schedule for a complete quote. Wayne was able to get to my house about 2 hours later to look at the job and firm up the quote. His actual cost with some upgrades, was within 1% of the phone quote. You can imagine that I was pretty happy to see this so we booked it. The install crew came out 2 days later to put in the new unit. The installers were very courteous and took a little bit of time to educate me on some additional maintenance items for the heater plus run through a few install options for my house. The guys worked quickly and within a matter of about 3 hours had fully replaced the unit, installed new service valves, ran a new condensate drain line, new expansion tank framed out and fully supported, added a drain valve for the recirculation loop in my house, and connected an external controller. The install in my garage is a basically a work of art. My home has a hybrid manablock plus a circulation loop to the master bath. The circulation loop never worked with the old unit and three different plumbers (including the original installer) never could get it to work, even after calls to the manufacturer. The best part of the replacement, other than the fantastic price, is that The Hot Water Guys were able to get the circulation loop working with the new heater. Now I don't have to run water in the master bath for 3 minutes before the hot water arrives. I walk in the bathroom, press a button on the wall and within about 90 seconds both sinks and showers have hot water ready to go. No more wasted water. Overall I am a very happy customer and would recommend them to anyone needing a new water heater. Plus the logo is pretty cool too! read more

Hot Water Guys is perhaps the most professional service provider I've worked with as a homeowner, maybe ever. I am a retired professional engineer so know something about the providing of professional services. These folks nailed it. From the first person I communicated with, to the scheduler, to the service technician who diagnose the problem, to the estimator who came out to size up the job (which was ultimately approved and finalized by their master plumber), to the team of three guys who installed the new machine, everyone was cordial, responsive, knowledgeable, and went out of their way to make sure all of my questions were answered. They worked together in a seamless way with no wasted motion and nothing fell through the cracks. They kept me informed at every step including giving me a heads up when someone was on the way out, always at the scheduled time, when that service person arrived, and when that person left. They never left me guessing or wondering about anything, they did the agreed work in a very professional manner, cut no corners, left things spotless, and charged me the agreed price, which I found to be a very reasonable price, especially considering all of the accumulated knowledge I benefited from by hiring then. I couldn't have asked for more. I have dealt with many plumbing companies over the years who profess to know about tankless water heaters. Mostly they don't. These folks are by far the most knowledgeable about the topic, the technology in general, and the manufacturers they represent in particular. I highly recommend them to anyone who needs a properly designed, sized, and installed tankless water heater solution without any drama, hassle, flimflam, or other time and money wasters. read more

NON RESPONSIVE! My hot water heater went out. It was under warranty and the manufacturer recommended this plumber. I called and explained the situation and had a case number from the manufacturer. The woman who answered, Carrie, wouldn't even set up appt without an authorization code. She wouldn't take the serial number the manufacturer gave me, repeatedly interrupting me. I offered to get the manufacturer on the line and she said that was my issue. RUDE. Found out from the manufacturer that an authorization code is given to the plumber once the plumber determines the damage and the manufacturer AUTHORIZES repairs - thus, an authorization code. The plumber came out and said the pictures the manufacturer needed he couldn't get unless he damaged the unit. I called the manufacturer - then called Carrie- another rude woman answered - and she said she didn't want to talk to the manufacturer - but he was on the line and said it was ok to damage the unit to get the pictures. She said the plumber would come back out either this afternoon or the next morning. She will call me back in 5 minutes. I called 6 hours later and was told he would have to come out in the morning. NON RESPONSIVE. I called at 8:30am the next morning for ETA and was told they weren't coming because they didn't want to work on the unit even though the manufacturer authorized it. NON COMMUNICATIVE. Why did I have to chase them? I called another authorized plumber, he came, got the pictures the manufacturer needed and fixed the unit. He said the answer HOT WATER GUYs gave me was a cop out because they probably didn't have the expertise. I could of lived with that answer. NOT HONEST? read more

I didn't get service from these people, but whoever is driving their vans needs to get checked. Driving like absolute rude idiots and being aggressive on the road is not the best way to get customers :) read more

They were recommended by another plumber regarding the installation of a tankless water heater. The crew did a good job installing my tankless water heater, removed the old water heater, and provided a good explanation afterwards. Sam S. was very professional and courteous. I use them to do the annual maintenance of my tankless water heater. To date my experience with them has been good. read more

The water heater in my 4th floor attic was leaking. Sam came by the next day and did a temporary repair and worked with the manufacturer to honor my warranty and get a new one. Hot Water Guys was extremely easy to work with, professional, and nice. Highly recommended. read more

Hot Water Guys are the best! I had a problem and called another company before I knew about the Hot Water Guys. When the technician arrived he could not answer my questions about the error codes on the unit I was having problems with, just wanted to sell me a new unit. I called Hot Water Guys and Sam came out and found I was having problems with the venting on and through the roof and he scheduled repairs for the following day. Problem fixed, and very reasonably charged. I also used them when my mothers tankless heater went out and Tom came out, looked at the unit and sold me a new unit well below market value. I won't ever use anyone else. It is nice that all their employees are very professional and only sell and service tankless water heaters. I will be only calling Hot Water Guys for my hot water needs. read more

Sam came out to help repair my hot water heater today after it would only stay hot for 10 mins and only go up to a lukewarm temp. Sam was on time, professional, and efficient with his visit. He was obviously very knowledgeable about my tankless water heater, and walked me through the possible problems. Sam also told me the different items I'll need reviewed in the future and at what frequency so that I could make sure everything continues to work smoothly. He fixed everything in about an hour and the price was very fair and exactly what I was estimated over the phone. I would highly recommend that you request Sam if you ever need help! read more

The awesome plumbers at Hot Water Guys provide fantastic, friendly service. They have installed two different tankless water heaters at homes I've have owned, and I couldn't be happier with the results. They were also very helpful in diagnosing and fixing other plumbing issues in my 100-year-old Heights home. The whole team is kind, clean, and hardworking. Can't recommend them enough. Thanks, Hot Water Guys! read more

After the freeze several of my neighbors had to replace their Rheem Tankless water heaters, that is the first time I saw trucks for Hot Water Guys. I decided my 8 year old Rheem Tankless Water heater needed service, so I called them. Brian came out and he was just great, he really knew his stuff and Brian told me of the constant training that they have to attend. I will call them again for sure. I highly recommend them to anyone. read more

called to get an estimate for a tankless water heater in our very standard one story house in Katy Texas master plan community. I was told on the phone be between $3400 and $4200. When the guy showed up he said it was gonna be $5000 and a smaller unit than what I wanted. On top of that he said there was going be disclaimer because my gas meter wasn't big enough but that was the whole reason he said why he gave me the smaller unit which didn't make sense. Classic bait and switch. read more

I had called to schedule service and a likely replacement. Unfortunately due to an unforseen medical emergency I had to call and cancel twice over two days (due to the medical issues). I just called again to reschedule now that my health situation is stable and they told me that it was policy to charge me for $25 dollars because I had cancelled last week. I even explained my health situation (very private information) and she said "I am really sorry but it is company policy." Lack of compassion and humanity changed my mind about even trying to work with this company. I will gladly spend my money elsewhere. read more

Thank you Tankless Hot Water Guys! You guys where very professional and the installation was fast! I look forward to having constant HOT water to doing dishes, laundry and hot showers. It's a pretty machine. Thanks again. read more

Outstanding! Dealing with repairs is tough and I dread it. Finding a good company, talking to receptionists, trying to get information, waiting for guy who may or may not show up, shows up later.....so when I set out to get my tankless hot water heater cleaned...I geared up for battle. I LOVE the Hot Water Guys! Why? Because they made my task easy, did a great, great, great job and at a great price. 1. Lauren, in their office, took my call and SHE KNEW what I was talking about. She requested I send her a photo of the tank and then she could give me more specifics...and I sent her the photo and she IMMEDIATELY called me back and YES she knew the answers to my questions. I had called several companies and one company had the owner answer and he told me he didn't know if they worked on Takagi water heaters, he would have to ask his plumber and call me back. ARE YOU KIDDING ME? The receptionist at Hot Water Guys knew so much I think she could do the job herself! 2. She explained my options and spoke in human words, not plumbish words that would confuse me. She recognized that the people we bought the tankless water heater from had not installed a release valve but she did not "bad mouth" them - just told me that was something we could install now or later if we ever wanted to and how to handle the tank without it. I admired her truthfulness as well as her professionalism. 3. The Hot Water Guys do Hot Water and they KNOW what they are doing! Brian was supposed to be at my house between 11 and 1 and at 12:36, he wasn't there. I began to worry ... and get smiffed...I called and Carrie (Lauren on the other line) and asked about arrival. She called Brian, found him in a hot attic at a commercial site and found he was tied up with solving a difficult problem. She called me back and apologized and then Brian called and apologized and once he had fixed their problem he came to my house quickly and fixed mine. He wasn't on time and I don't care. As long as he does a great job, which he did, and takes as much time on my problem as it needs so that I don't have a problem later --- I understand. I'd rather wait for someone who does a terrific job. Brian explained what he was going to do, did just that, kept me informed and made my tank hum like new! I am a customer for life. These guys (and gals) were GREAT! read more

Right price, Right product, Great Service Hot Water Guys replaced two 40 gallon tanks in my attic with one Rinnai RL75in for a 3 1/2 bath home. Between doing a ton of reading/research and getting three quotes, these are my conclusions: - Rinnai is the most dependable brand - Hot Water Guys' quote best fit my needs - My other quotes leaned toward larger or more complicated units. - Apples to apples, their quote was 10% below the closest quote. - In the end I spent about 20% less by taking their recommendation - The installation was neat and clean from start to finish. - The installers were nice, professional and thorough. Based on my reading and research, I would have over spent on a bigger or more complicated unit. In the end I chose to go with Tom's recommendation since they install these every day. After a couple weeks of use, I can say his recommendation fit our needs. read more

Sam from Hot Water Guys actually called to see if he could come early! He got here an hour before the appointed time and worked on my dreaded Bosch water heater. He diagnosed the problem and changed out the part but it still didn't work good enough, so he went back to to his company, got another part and came back to finish the job. Sam was determined to fix the problem and he did. We have hot water again, just in time for the cold weather. Thanks Sam! read more

I cannot recommend these guys enough. I had 3 different plumbers come to my house to address my water heater issues, and none of them knew what was going on. One told me I would need to replace the heater for $1800. The next told me he fixed the problem and the pilot light went out again immediately. Hot Water Guys showed up and were amazing. They ordered all the parts I needed on warranty, and they showed up on my doorstep free of charge the next day. He replaced the parts and only charged me for his labor, which was extremely reasonable. The best part about this experience is that they actually showed up on time! I highly recommend these guys. They know what they're doing, they're professional, and they are fair. read more

The office staff was very courteous and responsive to our water heater issues. Sam S. came by the same day, after hours to repair it. He replaced a broken part and even drained and flushed it. I would highly recommend Hot Water Guys! read more

We had them install an expensive unit. (almost $6k) We also paid additional for the kitchen sink to get hot quickly. After they left, we called and left a message because it was taking forever to get hot water in the kitchen. They never called back. When I followed up, they were very condescending and asked if I had reviewed the book of information they had left with me. Come to find out, I needed to download an app and call someone else to help. This became a time consuming ordeal to find out that the installer, Hot Water Guys, had not set up the "parameters". This involves going to the unit in the attic and removing the panel. I was unable to do that because the screws are so tight and will need further help to get started on "setting the parameters". Many details I won't include, but not happy with the customer service!! read more

These guys were awesome, and we couldn't have asked for better service. We called in the morning and by 1pm the tech was at our door. Sam was wonderful. He was very professional, extremely knowledgeable, and had us all fixed up in no time. Our heater broke as a result of the winter storm, and we were so appreciative and grateful that they made every effort to get out to us as quickly as they did. We highly recommend these guys for any of your hot water heater needs. read more

They are the warranty service for AO Smith water heaters. My unit installed 5/30/20 began going out in September. After a big hassle with AO Smith, I was referred to Hot Water Guys. Seemingly nice people but they charged me $35 as I am "not in their service area"( 44 miles per mapquest). Pleasant tech shows up with a new gas valve under his arm and installs it saying" they go bad all of the time ". A couple weeks later, same problem, cold shower. They come back and change pilot assembly and charge another $35, even though they didn't fix it the first time. Well a couple of weeks go by and cold shower again. By this time I'm dealing with the service manager, Carrie. Nice lady that says she will get AO Smith to send a new main burner. That gets replaced (fortunately no $35 fee this time). Two weeks later, no hot water only this time heater won't relight. I call Carrie, she returns my call Telling me she's done and it's up to AO Smith. So I paid $70 for nothing and they leave me twisting in the breeze. Lowe's won't take it back without an RA number from AO Smith which isn't likley, so I guess I dump the $600 junker, buy another brand and never consider either company again.HOT WATER GUYS, nice people that charged me $70 for what turned out to be nothing. I own a service company. I've been in my industry 60 years. I don't treat my customers like HOT WATER GUYS have treated me. " jus sayin" Tom Walne Fulshear,Texas read more

Brittany and Brian took care of my problem with a Rinnai tankless as quick as the part could arrive, when another firm let me go all weekend without hot water. Great, knowledgeable work, and very kind and responsive on the phone. Very reasonable on price and quick when it's an hourly job!! read more

Hot Water Guys​ http://www.hotwaterguys.com/ or call them at 832.673.0909. I strongly recommended them! Both my State Water Heaters stopped working on July 3, 2014 (Friday). They are both 2.5 years old and still under manufacturer's warranty. We troubleshooted according to the owner's manuals and although we got the Pilot lit, it wouldn't stay lit. And after a few tries, the status on the gas valve would not even flash. We called 2 plumbers on Saturday, 1 did not call back. The other said that since they were under warranty, the manufacturer would send someone to address the issue. I called State first thing Monday morning and they told me that Labor would not be covered and I should call a plumber. 1 plumber called me back and said I would have to pay $250 each for each gas valve upfront, and that to replace them both would be $200. So he quoted me $850 before he even came to diagnose my problem. When I called State to confirm this, they told me that they would reimburse me up to $186 for each gas valve because that was the list price...so I would have been out $128 for the plumber's markup. The other plumber didn't bother to call back. I got Hot Water's number from the list of preferred service providers from State. I told them my water heater symptoms and they told me it was probably the gas valve and / or burner assembly. They told me not worry because once they diagnosed the problem, they had ALL THE PARTS IN THE TRUCK! So I would not have to pay upfront for any parts and I would not have to wait for parts to be shipped! They explained that they charged the $145 for the first hour, and $100 for each hour after that. I was concerned about how much time this would take and they asked the technician (Kurt) right there and he said 1.5 hrs ($195). I booked my appt, they were at my house in less than 2 hrs! They called ahead to let me know they would be early. The actual work took a bit longer than 2 hrs, but they still charged me the promised rate of $195. My water heaters are up and running and I am so thankful for great companies like Hot Water Guys read more

Hot Water Guys congrats and thank you for being the only company that did what I asked without trying to lie, cheat and steal. Integrity goes a long way and you have earned yourselves a loyal customer. I called several other service providers who turned out to be complete liars, con artists or didn't bother to even call back. Thank you for a job well done. I highly recommend you!!! read more

Unreliable and unprofessional - even the lady that answers the phone is rude. Our hot water hasn't been working for over a week now. We have called multiple times and have been pretty patient with hearing back - but never get a call back. Used to think it was a great company, but then I realized they don't really care about their customers (or are too busy) read more

I had warranty work to be done on a hot water heater and everyone was great from the get go. Lauren called because there had been a cancellation and the tech was able to come our earlier than planned. She was super sweet and very personable every call. Sam came out in the nastiness of rain, thunder and lightning and took care of us. He diagnosed the problem, took care of it and was on his way. I will definitely use them again warranty work or not!!! Thank you for being quick, efficient and getting our hot water back to us! read more

Excellent service, reliable and honest..a rarity nowadays! You won't be disappointed!!

Sam our special thanks to you for the wonderful job you did on our brand new water heater. Your knowledge, professionalism, expertise and dedication to get the job done is very much appreciated. Cold shower are a thing of the past for this family. "Ruth Hill & Family". We highly recommend Sam. He gets the job done. !!! read more

Sam = awesome. Nice guy who wants to get your water heater working again. I have a new property with Stiebel Eltron tankless water heaters. When the hot water was not working, I spoke to a representative from Stiebel Eltron who referred me to Hot Water Guys. Sam came out the same day and replaced the water filter but it did not solve the problem. After trouble shooting for a while, he then spoke to a representative from Stiebel Eltron and learned that the prior installer did not hook up the wiring properly. Although a simple fix, I am relieved that Sam was able to locate the issue and provide me hot water again. Thank you Sam! read more

From the start, they were great. Very accommodating: I called on a Sat AM after having been told by a few other local plumbing companies that I had to wait over 2 weeks to have someone service my tankless water heater. Brittany (sp?) was incredibly helpful and resourceful over the phone and Brian arrived at the appointed time (within 2 hours), efficiently cleaned/flushed my heater and took time to answer all of my questions. Overall very positive and professional experience. Problem solved, great experience. read more

My family has had an ongoing business relationship with Hot Water Guys for over a decade. We keep coming back for their professionalism, expertise, and outstanding service. Their price for service calls are more than reasonable. When I call for either repair or service to my aging tankless water heater, I ONLY ask for Brian. My family even went without hot water for over a day last week while we waited to be able to schedule Brian. He's patient, extremely knowledgeable and great at communicating in layman's terms what I need to understand about my tankless system. I highly recommend Hot Water Guys, and in particular, BRIAN! read more

Amazing customer service from beginning to end. Our hot water froze overnight & the kind woman I spoke to was able to squeeze us in on a full day. When Sam showed up right on time, he found that the situation had actually resolved itself & the hot water was running again...He gave me some tips on how to solve the problem in the future & didn't even charge us for the trip. Truly a pleasure to find such a top notch & honest company! And thank you Sam for not making me feel silly wasting your time & for your expert advice! read more

Hot Water Guys - this is the new sexy! my tankless hot water heater. saves space! on demand hot water! i love it! thank you! - Plumbing Near Me - Houston, Texas

I had a defective Honeywell Gas Valve replaced by the Hot Water Guys under warranty from State Water Heaters on Oct 1. After the installation repair, my wife occasionally noticed the smell of the sulfur from the natural gas when she goes in the garage. On Oct 19 morning I was overwhelmed with the smell as I left for work. I did the soapy water test on all the connections around the water heater. The brass fitting that connects the pilot tubing to the Honeywell controller was loose. It took a 1/4 turn to tighten it. I contacted the Hot Water Guys asking for a partial refund. They have refunded the total cost of the service call and have made an adjustment to their employee roster. read more
