Al is a standup, honest guy, his work is good, and his price is fair. Seriously, everything you want in someone you're entrusting a big decision to. We had him here to replace our radiant heat boiler in our Eichler. Starts with Al being very responsive when scoping the work. (Compared to another company who sent a tech to see if they could repair it, then I had to ping them a few times to get a quote.) Al obviously knows his specialty, was able to give me a quote quickly based on some photos of the current boiler he would be replacing. And his pricing is very reasonable. Then during the job Al is capable and communicating, like when the heater was late in arriving, or when our ancient wiring and the new thermostat were not playing nice and we needed to think of a new plan. This was especially challenging in an Eichler, where running new wiring is nontrivial, so I'm glad after a few other options, Al had the idea to use a wireless thermostat. It's been a couple months now, and everything has worked thru the winter, and I'm really happy about it! Thanks Al! read more

If you're looking for someone knowledgeable, reliable, and genuinely professional when it comes to tankless water heaters--look no further than Al at Just Tankless. My 84 year old father had a defective Rinnai unit that was giving him endless headaches, and Al was a total lifesaver. From the moment he got in touch, he was incredibly communicative and timely. He explained exactly what the issue was, what needed to be done, and patiently answered all of our questions. It's rare to find someone who is not only highly skilled but also so patient and informative throughout the entire process. It was clear from the start that he genuinely cares about doing the job right and making sure his customers feel taken care of. We are beyond relieved to have found him and would absolutely recommend Just Tankless to anyone dealing with tankless water heater issues. Five stars all the way! read more

I HIGHLY recommend Al. I was impressed with the knowledge he has. He came over, removed our tank water heater, and installed a tankless water heater. His price was very reasonable. All work was done in about 5 hours. read more

We HIGHLY recommend Al. I can't begin to tell you what a knowledgeable, professional, kind man he is. We called 5 plumbers and he is the only one who called us back. He also took the time to help us with our tankless hot water heater issue. We were able to fix the problem with his instructions and he refused to bill us. I appreciate his professionalism and highly recommend Just Tankless for all your tankless hot water heater needs. read more

Wow, I just called to get a quote about upgrading my tank water heater, to tankless... and what a horrible experience. He gave me a quote over the phone without seeing any pictures or anything (just answered some questions), and I asked if venting for a condensing unit would be a problem and if it was apart of the quote he gave me. And Al literally blew up, "where did you hear it was difficult, that's BS", and then "if you want to argue go find someone else".. I'm just in shock, I was just asking if it was apart of the quote to do any of the ventilation needed for the new unit, especially since he hasn't even seen any pictures of my garage or the current tank. He didn't even answer my question, he got so triggered by my question, he became extremely rude and started yelling at me. I was so in shock, I hung up while he was yelling, like why am I getting yelled at for asking a question about the quote. What's crazy is, I was really excited to go with someone who specializes in tankless, but wow. If you're getting a quote from him, make sure you stay silent, don't ask any questions about it. He's the expert EDIT: After leaving my honest review, the business owner contacted me with legal threats, demanding that I remove it. They also reached out to my employer in an apparent attempt to pressure me, despite my inquiry being for personal, residential use. This ongoing behavior constitutes harassment (colloquially speaking) and has only reinforced my concerns about their professionalism. I stand by my review, which is based on my firsthand experience. Consumers have the right to share their interactions with businesses without facing intimidation or harassment, and prospective customers should be aware of how this business responds to feedback. read more

Hello Al, I wanted to say thanks for helping me out yesterday. My Water heater was not working for two days and this happened on the weekend between Christmas and New Years. Fortunately I was lucky enough to find the Phone number to Just Tankless and it was open on that Sunday. You were very professional and friendly plus you had the parts I needed and traveled to my home to install them and within 30 minutes I had hot water. I felt the price was very reasonable as well given this happened on the weekend and during the Holiday Season plus you had the parts. Thanks again Happy New Year read more

. We were not getting any hot water for my 2-year-old Navien Tankless water heater. I called and spoke to Al at 1 pm, and he said he could come check it out at 4:00 pm later that day. Al showed up on time and went to work. He made a few calls, figured out the issue, and showed me the problem, which was a stuck sensor valve in my Navien. He had the replacement part in his truck. He was done in less than an hour. Great service, and iI would definitely use them again if needed!!! read more

This company is amazing. I was able to talk with Al over the phone. He knew exactly what needed to be done in replacing an old existing flash water heater. He was out within the week, VERY REASONABLE charges and was done within less than two hours. I had another estimate from another local company in Santa Cruz that was over double what Just Tankless charged me. This is the company to go with. read more

Great to schedule and level of technical knowledge of job is amazing. I highly recommend.

Short but insightful story. Purchased an NORITZ tankless water heater last year. The highest heating temperature displayed 120% After exhaustive attempts to raise the temperature I believed I had to purchase a new tankless unit. Called around and was directed to Tankless.com. I called him, (owner) and was prepared to purchase a unit that would cost me in the neighborhood of 3K. TO MY AMAZEMENT THE OWNER OF TANKLESS WALKED ME THROUGH THE PROCESS (TWICE) SOLVES MY ISSUE AND AT NO COST. I will, and I suggest to you, to use this company. He was courteous, patient, and could easily have cost me $$$$. Super to find HONEST people in this world!!! read more

Al replaced our old tank heater with a Navien tankless just over a year ago. He's friendly and a very knowledgeable guy - it was pretty clear he had done this for a while, and was not someone who just could handle the easiest install jobs. AFAIK, this company is largely a one-man operation, Al will answer the phone/emails, come in his truck, and do the work himself. He spent a few hours and completed the job within a day. We had a couple issues with the heater since install. 1. The heater abruptly malfunctioned, and displayed an error while not outputting any warm water. Al responded at the end of the day and came out the next day to replace the PCB. He mentioned this was a known issue, but Navien was not proactively replacing PCBs on past installs. 2. The heater would very slowly drip water in certain conditions. Al came out and said it should be normal and resealed the connections, but I keep a drip tray under the heater now. Overall, a good company / individual to work with for tankless heating, it seems my issues were more likely due to Navien than the install, and Al was very responsive in helping evaluate them when they did come up. read more

Just Tankless - Navien PCB failure - Al replaced it the next day - Plumbing Near Me - Los Gatos, California

Like many on here, we had our water heater break after 17yrs. I decided to call the company (Just Tabkless) my neighbor used. I even asked my neighbor what he thought about the installer. He said Al is very knowledgeable and courteous. And did a great job at his place. I texted Al and he quickly gave me a quote on a Navian tankless, which is what I wanted. Al came over the next day, and in no time, he was finished and tidied up. I would not hesitate to contact him for future jobs. read more

Al fixed my 10 year old Navien combination boiler that started failing with a "loss of flame" error code. He asked me to do some experiments and had an idea what might be wrong even before he arrived at my place. In the end, he just had to replace the flame sensor that was badly worn. He knows Navien boilers well. read more

Things started off good. They gave me a reasonable estimate and offered to visit in person for no charge to write a detailed quote. They never confirmed that they were coming, and later sent me an email that they couldn't find the road that my house is on. I called them back a few minutes later, but they said that they were not interested in doing business with me. Very unprofessional. I got the impression that they decided they didn't want to do business with me for some other reason and made up the story about not finding the road as an excuse. Alternatively, if I take their story at face value, they are the kind of company that will abandon a project at the first sign of difficulty. I guess it is good that I found that out before any money changed hands. read more

I've never really dealt with such a proficient and expert company. When my old tankless water heater began leaking, I called Al at Tankless.com. This was on a Saturday. He was there in less that an hour. I was stunned. These guys are subject matter experts on all things tankless (as the name implies) But more than that they do what they are timely, honest and efficient. Within a 15 minutes, Al knew EXACTLY what the problem was and how to fix it. As soon as he left (within 30 minutes) he emailed me a quote, told me precisely how long it would take to fix and volunteered to come the next day (SUNDAY). I'm' still a bit taken back. He came, he fixed, he rocks. He even installed a water filtration system to soften the water. Amazing. \ Never been happier with a vendor. If you need/want a tankless water heater system, don't use anyone else, you'd be wasting your time and money. I know, I've been there, done that read more

Our old tank water heater stopped working in the morning. We called Just Tankless, and he said he could come out the same day. He took the old water heater and hooked up a Navien tankless water heater. We appreciated his ability to install the same day as well as his professionalism. The job was done well. read more

Al helped fix my Noritz Tankless this morning. The heater had been giving me issues over a few days and water was intermittently not getting hot. I called another company and they checked the error codes but couldn't fix the problem..and then yesterday, it just stopped turning on. Al was responsive and frank on the phone that he couldn't help me with an intermittent issue given there is no consistent repro. After I called him a second time when hester stopped working, he stopped by and diagnosed the flow sensor to be the issue in no time. He cleaned and everything was working again. He also commented on my pump and polyphosphate filter setup and gave tips on how I could flush the heater myself. You can tell he has a in-depth texhnical knowledge of this . I would highly recommend his services. Thanks. read more

Very knowledgeable, responsive and honest. I had these guys check my Tankless and they repaired it after quickly diagnosing the problem. Another company I had called wanted to replace the tankless at a great expense. I highly recommend these guys. read more

Al Johnson is a pro. New homeowners and no experience with the 10+ year old tankless water heater that started leaking. Al responded to our call right away and recommended a new water heater which he had in stock and ready to install. After doing our homework on the Navian model he recommended, we proceeded with the new water heater and Al installed it during a storm. He was knowledgeable, efficient, tidy and pleasant to work with. He also disposed of a useless old water softener that was taking up a lot of space in the garage. Highly recommend Al! read more

Just Tankless - Plumbing Near Me - Los Gatos, California

My Takagi water heater stopped working and Al was able to fit me in soon and arrived promptly. Al quickly diagnosed the problem and had a replacement part with him. He made the repair in about a half hour and the water heater now works perfectly again. I had done some diagnostic work myself and, while I was unsuccessful in remedying the problem, Al suggested that I might have more luck with more detailed error codes that come with a remote control accessory. He thought he might have an extra one and he offered to bring it by. Two days later I found the remote control in my mailbox! Al definitely went above and beyond and I really appreciated his honesty, transparency. read more

Al does excellent work. He has installed two Rinnai tankless water heaters for me. No problems after five years on the first and 3 years on the second. He is also a great contracting resource. Upgraded old tile flooring with tile. read more

Our NAVIEN water heater went out a few weeks back. I thought the repair would be a pretty quick, straightforward process but I was wrong. I went online to find a group certified technicians that were qualified to work on our brand of water heater. I called the technician on the list which was closest to our home. It wasn't Just Tankless - it was a different company - Clap Construction in Mountain View. Phillip from CLAP Construction and his assistant came and spent an hour and a half poking around and said he wasn't able to finish, but that he would need to come back in the morning and finish up. He comes back in the morning for another hour and tells me the bad news... "you're going to need a new PCB board along with a new valve and igniters." It was going to be around $1500. He suggested we just get a brand new water heater since other parts were bound to go bad in the future...blah, blah, blah. After hanging up with him, I wanted a second opinion (I didn't trust this guy.). I called Just Tankless and spoke to the owner named Al. He was a really nice, honest guy. I told him the story and how I wanted a second opinion. It was a Saturday and he didn't have time but he said he would squeeze me in somehow later in the afternoon. He showed up, took a look at the water heater and told me that the other guy mis-diagnosed the problem. It was only the *valve* that needed replacing, everything else was fine. The valve was only a few hundred so Just Tankless saved me over a $1000, maybe more, since I was considering buying a brand new water heater. I had to order the valve and overnight it, but the water heater was fixed in no time, thanks to Al. The parts that Clap Construction deemed defective actually weren't bad. Al told me that they were perfectly fine, he just told me they were bad to make some money off me. Al is a professional in every sense of the word. He was knowledgeable, quick, efficient and on-time. He really saved us from being without hot water for days. I was very grateful to have found him especially after running into the scam artist from Clap Construction. If you're having water heater problems, Al is your man, 100 percent. Can't say enough good about Just Tankless. Avoid Phillip at Clap Construction - HUGE red flags. Avoid them like the plague. read more

Al fixed my tankless problem within 10 minutes. My 9 year old tankless quit working this morning, no hot water. I contacted the installer but they couldn't come out until Monday. I discovered Just Tankless on Yelp and spoke with Al. He asked a few questions, and although he was busy he said he'd be here in 30 minutes. Amazing! Problem solved! Just Tankless will be my first call from now on! read more

Wonderful work by Al. He was fast and worked hard. He was nice to my kids and treated us well. He was Safe and wore a mask. The unit is great and we would certainly call him for another project. read more

Just Tankless - New Gas Tankless with recirculating (WiFi) - Plumbing Near Me - Los Gatos, California

Recently I had a leak in my old 50 gallon hot water heater. I thought years ago that if I ever had to replace it, I would consider tankless. Unfortunately when your hot water heater breaks is not the time to start research on how to do that. I called my plumber who gave me an estimate on replacing the old dinosaur but on a whim I looked at the map near my home and saw 'Just Tankless' and called and spoke with Al. In that one conversation I heard everything I needed to and decided his company was the right one to use. I got lucky and Al had a cancellation and came that day and installed a Navien tankless system. Al was very professional, down to earth and extremely knowledgeable. Being an engineer myself, I enjoyed 'nerding out' a bit with him and his own engineering background and I had full faith I was making the right decision with this switch in technology and am very happy with the end result. 'Real people' who you believe in that run businesses seem to be more hard to find these days, Al is one of them. Thanks Al! read more

Al and his colleague changed a defective tankless heater that was leaking water with a brand new Navien one. The problem did not go away and the new heater kept leaking. They both came back three more times and they did not fix the problem but rather rerouted the leakage to the drain rather than the floor. The heater had intermittent issues as well. Apart from not getting clear answers, Al did not provide a two-year warranty as he agreed to in the beginning, and took the job although it was far from his location, which I didn't know in the beginning. In conclusion, you need to hire a specialist and Al is not as knowledgable. read more

Al Johnson of Just Tankless embodies what good professional service is and should be. His care and workmanship comes through from start to finish. I recently had a tankless water heater installed by Just Tankless and am completely satisfied. I recommend this company. read more

Al is absolutely the BEST. He is very professional, he has outstanding communication and a he is a master craftsman of his trade. I should say tradeS because he is a jack of all trades. You don't need to look any further for your hot water heater issues because Al can take care of everything. My water heated died in the morning leaving me with a bunch of screaming women that needed to take showers. Rather than try to fix it (the water heater is about 11 years old and has never been serviced) I opted for a brand new unit. I called Al and boy am I glad that I did! He was kind, helpful and he understood the emergency that I was in. It turns out he is a rep for Takagi (my old dead water heater) and he had the new updated model in stock. He was able to move some of his current jobs around in order to accommodate my situation and he was at my house in about an hour. His work was quick and his installation was clean and professional. He is also a very nice person and interesting to talk to. I have already referred him to friends and family. I wish all contractors were like him he embodies true professionalism. read more

My tankless water heater stopped working and I called just tankless in the morning. They came the same day in the afternoon and fixed the issue quickly. I would recommend Just Tankless with their fast, friendly and professional service. read more

I have a 5 year old Noritz tankless water heater that was leaking on the inside and there isn't supposed to be water on the inside! I found Just Tankless on the Noritz website as a certified installer. I called them on Saturday morning (because all water leaks occur on Friday night after everyone is closed for the weekend). There are 3 numbers on their website, and Al picked the phone on one of them, thankfully! Al ended up coming out and was super knowledgeable and honest and gave great advice. He diagnosed it quickly as a faulty heat exchanger and called Noritz right there and texted them pictures and since it was under warranty (parts only, not labor), they sent me the parts for free. Al informed me that it would be about 5 hours to replace it. And in our area, the cost of living is so high that the going hourly rate for plumbers is so high. The part wouldn't arrive for another 2 or 3 days so I had to wait and Al said that he unfortunately didn't have the time in his schedule to replace it himself. It was difficult to find anybody to replace it, but I did find someone solid and I am grateful. But I would take Al and Just Tankless any day. He was kind, comfortable, took time with me, had true empathy, and dealt very honestly. He told me a very simple solution to something that I should add to my system to prevent this from happening again, which i now have added. This is a quality choice for a tankless system install and very knowledgeable about repairs. Thanks Al! You are awesome! read more

We had an issue with our existing tankless water heater, Rinnai, no hot water. Called a company that we have used previously for regular service. They came out out today, Saturday, and determined after calling Rinnai text support and reading the display on our control box that there was a flow issue. Technician says we would have to order a new part for replacement on Monday, wait for delivery and replace the new part. I assume this would take a week before completion and a week with no hot water. Decided to call Just Tankless for another opinion based on Yelp reviews. Al responded to my call and came at 5:30. After a couple of minutes, he knew exactly what was the issue and explained how he could service the problem. He removed the cover, took out the part and disassembled to remove the particles that were preventing flow. Replaced everything and we were in business again. What impressed me was that Al knew tankless water heaters thoroughly. When another was ready to order a new part and replace, Al fixed the issue for a service charge. The difference is that there are technicians that can follow the service manual and read the display. Then there are truly professional technicians who understand the total mechanics of a system and act accordingly. It was not just the cost difference. We were able to restore our hot water immediately and no longer had to anticipate cold showers for a week. Al is a true professional and highly recommend this company for your tankless water needs. Thanks Al! read more

I can echo the other reviews. Al came in to check my broken water heater within an hour of my call on Friday afternoon. By Sunday noon I had a new heater. I called around for a quote and Al was the least expensive. read more

I wanted to wait to see if everything was done properly with no leaks or issues after 6 months of use . There is none. Al did a fantastic job and was very knowledgeable about the entire process. Would recommend to anyone looking for a tankless install read more

We had a Rinnai Tankless that was not installed properly and had a small defect which we had the original plumbers attempt to fix, but they gave up. Al was able to not only able quickly identify the problem, but fix it quickly as well. read more

Just got a tankless water heater installed. In many places this is needlessly complicated - but with Al you get an excellent job, great quality, friendly service, reliable, and everything on time. I can highly recommend it. read more

Our water heater stopped working, and he came out to see us the same day. He checkout it out, figured out it was the igniter, and told us how we could order the part ourselves for $30. Since it was Friday night, we would have to wait until Monday to order the part, and be without hot water for almost a week! So before leaving, he figured out how to hot wire a different brand's igniter to our water heater so we could have hot water until the new part arrived. Life saver! read more

Al is extremely rude, defensive, and unprofessional. I got a quote for a tankless water heater, and had a plumber out for something else and had him take a look at the proposal. He told me that the unit Al suggested would not work because of some pipe measurements or flu vent size or something. When I emailed Al asking for reassurance about this, he accused me of pitting him against other contractors and replied "Ok, whatever. Good luck with it." WTF? I never said anything about getting him to lower his price or defend his choice. I've never bought a water heater before and I literally just wanted him to explain it to me! When I tried to explain that I just wanted to make sure the unit was going to work, he said "we can not possibly be expected to defend our position" and "I will not get in a position to argue back and forth who is nearly as qualified as we are" and "Playing two contractors against each other is not something we play along.." Huh? Just explain to me why the other dude says the unit you suggest won't work and why you think it will! Geez! This dude seems crazy. Ironically, Just Tankless signs off his emails with "Just Thankless." Yep, you got that one part right Al. read more

Had Al replace water heater with a Rinnai tankless system . After two years it had a leak which Al covered himself . He came out and replaced the unit with a new one and extended the warranty . His word is his bond and when he says I'll handle it , he means it . Great service and more importantly great attitude read more

I have recently upgraded the power circuits in my home to support a tankless water heater. I have a list of models that would provide the necessary flow, but I deferred choosing one until I selected a plumber (to get their feedback on models they trusted). After receiving this information, Al told me that you can't install electric tankless water heaters, that it was impossible project, and it couldn't be done. WHAT? I persisted to try and understand what he was saying, but he just spouted a stream of nonsense: 1. It's impossible to install enough circuits -- two 60amp circuits or three 40amp circuits? This isn't rocket science. 2. You can't get enough power from PG&E to power one -- I have it already 3. It will cost you much more what a normal water heater will -- Energy Star and many other installation reports indicate 50% savings at our flow rate 4. Nobody buys electric tankless -- Which is why they're sold at Home Depot, Lowes, OSH...? Yeah, those stores stock products that nobody uses. Seriously, he just told me my project is not doable and yet he can't justify a single thing he said. This wasn't a voice of experience raising practical considerations, it was someone who wanted to avoid a prepared, intelligent customer. This is a predator. Stay away. read more

Al is the most conscientious contractor that I've worked with. We had an 9-year-old Eternal tankless that started leaking. Al responded to my call for emergent service. He went more than the extra mile by troubleshooting different parts of the old water heater until he exhausted all the repair options. His engineering background came in handy throughout. He truly gave the best effort, went above and beyond. With all the repair options exhausted, we moved to plan b - replacement. Al patiently explained to me the pros and cons of today's leading brands of tankless water heaters. I decided to go with Rinnai. Al and his right hand man Armando got the new water heater installed within half a day. Throughout the service appointments, Al and Armando demonstrated outstanding professionalism, attention to detail, and great communication. Now that our new water heater has been running for about a month. It's long overdue to extend our sincere appreciation for the great service that Al and Armando provided. Let me spread the word here - if you want a tankless, go to Al; if you don't have a tankless, consider to get one, and go to Al. He's hands down the best tankless contractor out there. read more
