We cannot say enough about what a good job they did replacing our tankless water heater. Professional, courteous and skilled at a fair price. What more could you ask for? read more

They replaced and installed my water heater with a tankless in less than 5 hours within a week after I called them. Service was great and the price was over 50% less than what HD quoted plus they informed me about the rebate that SoCal Gas was giving which dropped my out of pocket cost to less than what I paid 20 years ago to install my 40 gal heater! Tankless heaters are the way to go. read more

We were not getting hot water through tankless water heater. It was a very old unit, but technician, who came out promptly, worked hard to try to get it going. When it became clear it was better to replace the unit, we asked if they could do it. The next morning, the new unit was installed. Cannot say enough good things about At House! They are prompt, do excellent work and very easy to work with. Reasonable pricing as well. Highly, highly recommend! read more

At house and Hiro are the best!! Hiro replaced a Rinnai tankless water heater on the same day I contacted him with a very competitive price. On top of that, an excellent and quality job are what you get from Hiro and his team. Thank you, thank you, thank you!!! read more

Hiro is honestly the best in the business. After our home warranty company sent out 3 different plumbers for our tankless, I finally hired Hiro for the job and I'm so glad I did. He was on time, worked quickly, very courteous, extremely knowledgeable and professional. And his prices were way lower than the plumbers estimates. I will never let anyone else touch my hot water heater, I'm so happy with the service I received from At House. Thank you!! read more

My wife and I have nothing but good things to say about At House, Hiro-san, and Taka-san. They performed a bathroom remodel for us, and because Taka-san did such a great job with the tile work, we asked him to also install new tile in our entryway. He was meticulous, always on time, patient, and very accommodating to how we wanted the work to be completed. We've worked with many other vendors but none have shown the level of respect, attention to detail, and were so comfortable to work with that we would not hesitate to give them our highest recommendation. read more

Our hot water tank started leaking on Sunday - After calling a number of places, Hiro was able to come quickly and professionally install our new tankless Noritz heater on Tuesday. His price was extremely fair - better than the other installers. He was professional, quick, and did a great job. He even gave us information on how to apply for an energy saving rebate. Thanks! read more

Contacted a couple companies and obtained quotes. Hiro from At House came in person to inspect the existing water heater and set up, and to determine all necessary work. He specified his choice of replacement and explained how this tankless unit would match the output of my 75 gallon water tank. Pricing was comparable to the competitor, but I felt that Hiro's apparent expertise would make the difference. Hiro and his team came on time today with all the tools needed. They worked neatly, and efficiently to the job in a professional and clean manner. Hiro and Makito executed the installation and cleaned up everything during and after their work. read more

Look no further! At House is the company you should hire for your water heater, water filtration, and repair needs. Unfortunately woke up to no warm water and a broken water heater. Parts were still under manufacture warranty, however, needed a company to help me install the components I received. I started searching Yelp and received multiple price repair quotes and estimates. I decided to go with At House due to their pricing and professionalism and expert knowledge after speaking with Hiro. He made my decision easy and I decided to hire them. Within minutes, he was able to have a technician which arrived and got straight to work. Repairs came out 100% perfect and got my family back to having the warm/hot water we were dying for. Overall, working with At House and Hiro I am completely satisfied with the customer care and craftsmanship they provided me. I will definitely be calling them and referring business to them!! Thank you At House!! HIGHLY RECOMMENDED!!! read more

I can't say enough good things about this company. Our Noritz unit was installed by them back in 2014 and recently developed a water leak. I phoned in the issue and in under 3 hours we had service ring our door bell. Parts were needed for the repair that required an overnight wait, but the serviceman left us with hot water service while we awaited the parts. He returned the next day and completed the repairs, all parts were under warranty, so we only had to pay for labor. I highly recommend Noritz Tankless Water Heaters and this wonderful service company. Domo Arigato Gozaimasu! Dave West Westminster, Ca. read more

Kevin from At House was absolutely amazing. He was on time and very patient while explaining the service and workings of our Noritz unit. He did some troubleshooting and got our unit back on track. We unfortunately did not have a Noritz certified company install the unit two years ago. Kevin brought the unit up to company specifications and did so in a timely fashion. We're so pleased with him and his work ethic that we scheduled a return visit to do some additional work on one of our bathrooms. read more

Hiro was a pleasure to work with, and we are very pleased with the tankless water heater install. I felt very comfortable with Hiro's recommendations. No upsell or pushiness, just helpful information. The work was clean and professional. Highly recommended! read more

At House - Water Heater Installation/Repair Near Me - Irvine, California

I've read about At-House from some local Japanese magazine when we installed a Japanese style deep tub several years ago, thinking that when our tank goes out, that's the place we would call to change it to a tankless one. Well, that time has come this Tuesday evening. We contacted Hiro through Yelp. He responded promptly and came the next day. Hiro answered our questions clearly and honestly, and he gave us a fair quote. We decided on a medium size Rinnai that has a $225 rebate from SoCal Gas. His team, led by Kevin, came the next day. Our old tank was housed in a tight pantry closet. How it got in there was a myth since they had a hard time getting it pass the opening. We thought about cutting out part of the pantry. But through Kevin's ingenuity and hard work, he and Satoshi finally took the old tank out without a scratch. They worked diligently till the early evening. And within 48 hours after our old tank died, we have hot water again! I highly recommend At-House for tankless water heater. They are prompt, courteous professionals who get the job done right. At final inspection, Hiro even went the extra mile of installing our Dyson vacuum holder onto the wall where it shares the same outlet as the Rinnai. They cleaned up the place, both interior and exterior before they left. We are extremely happy with their service and our new tankless heater. read more

Our water heater died after 19 years of use. I spent a night trying to learn everything I could about water heaters, and the next day online trying to find someone who really knows tankless systems: not just an occasional installer, but someone who is familiar with all of the major brands and certified by the top-line manufacturers. Most plumbers are only trained on one supplier and rarely install tankless. At House was the only installation/repair place I found in my area with pictured installs of multiple brands and consistently positive reviews. I finally gave them a call around 4pm, and Hiro answered right away. He said he could stop by in about 15 minutes (seriously). It would just be a minimum inspection fee, which could be applied to any repair or replacement. Sure, that would be no problem! It's better than another day without hot water. Hiro arrived just as I cleared out the garage area around our heater. He (like his crew later) was wearing a proper N95 mask. He opened my old system and read the error code -- it was a blown control board that probably wouldn't be worth the cost of repairing. I agreed. He then looked at the existing venting and talked to me about comparable sizing and water demand, before recommending a Rinnai condensing model. I was a little surprised by that, but he explained that the newest Rinnai models have a 2" venting feature that allows a pipe to be fed up through my existing (old code) pipes and out above my roof. The other models, which are also good, would require a new 4" vent installed to match the current code. Awesome, I never would have thought of that. He suggested a mid-range size would match my current use requirements, but I wanted the larger model just in case. No problem. He quoted me the same price for the unit as advertised online and an incredibly reasonable amount for plumbing and labor. I asked when they could install. Hiro said "tomorrow, about 9am". Yes! Two of his crew would show up first and he would join later to do the second-story roof pipe install. They all knew their stuff. They worked as a team, did a careful and clean install, used the best parts, and were considerate of us the entire time. The only complication was a custom pipe to route a condensation line to my laundry drain, which had to be carefully routed around a dryer vent. The whole install was done in about 5 hours, with Hiro and two of his crew installing, and another person delivering components, lunch, ladders, etc. All I had to do was open and close taps inside the house, just to avoid the need for the crew to come inside. Hiro even painted the new exhaust pipes on the roof the same color as the existing ones (an HOA requirement) without me asking. A normal plumber would have charged me twice as much just for the labor. The entire experience was excellent. Our new Rinnai RU199iN system has been running a week now and has zero problems, no leaks, no weird noises, and considerably more hot water than with my last system. read more

Hiro was awesome! Gave me the best price for my tankless water heater flushing which I am required to do once a year. He was nice and communicative. I will for sure use them every year! read more

Hiro came highly recommended from the tankless water heater company and he did not disappoint us. He came within 24 hours and was knowledgeable, professional, and courteous. The installation team came out the next day and was sharp, precise and meticulous. We are extremely happy with the job they have done and would highly recommend them. I did a lot of research before choosing them and they were reasonably priced. read more

I had old Takagi tankless water heater maintenance done by Hiro and his team. Punctual and fast clean work.reliable people. This Japanese tankless Hester works great! read more

I am a laundromat owner and needed to change tankless water heaters. Mr. Hiro responded so fast and gave me a reasonable price. The technicians were kind and professional. Maybe I have to change two more water heaters in near future and I will call Mr. Hiro again. read more

You've got to give credit where credit is due. I called these guys about repairing my Takagi tankless water heater. They called me back within 10 minutes. I explained what the trouble was and they said they would arrive within 2 hours. Much to my surprise, the technician was here in under an hour. I explained again what the trouble was an what I had done to troubleshoot the problem. He seemed to understand. He looked at the heater for couple of minutes and asked me to turn on the hot water. So I did. Fiddled around for a couple more minutes and asked me to turn it off. He went to his truck and came back with a cable. He plugged it in and asked me to turn on the hot water again. Voila!!! Hot water was running again. He explained what had gone bad, said it would be a week or so to get the right replacement. $30 for the part and $300 for the labor. I thought that was expensive but certainly less than other guys had quoted in several scenarios. I paid $100 for the visit, which was then credited at the time of repair. When they came back, they were very flexible on scheduling. It was a different technician that came back to do the repair. He got right to work. It took him a couple hours to perform the complete repair. He literally gutted the whole water heater. I'm pretty handy around the house, and let me tell you, this would not be a DIY project. I wish I had taken a picture of the dismembered heater. Not for the faint of heart. Long story, short, it took him 2 hours for the job, and I paid an additional $180 for the repair. That's a total of $280 for 2 visits and about 2.5 hours of labor, and includes the cost of the part. The guys are awesome in customer service, speedy, and reasonably priced. Who says you can't have the Holy Trinity? Good, Cheap, and Fast!!! read more

Had an old tankless water heater that needed replacing. After doing my homework and calling/emailing over a dozen plumbers in the OC I found At House on the Rinnai website as a certified installer. Hiro responded to my inquiry right away with a detailed breakdown of the costs, and within 24 hours had my new water heater installed for $600 less then anyone else. They were very professional in every aspect from putting on botties to protect my wooden floors to cleaning up after themselves and doing an overall terrific job. I would highly recommend At House for anyone looking for a tankless water heater! read more

At House - My new Rinnai tankless water heater! - Water Heater Installation/Repair Near Me - Irvine, California

This a little overdue but we are so happy that we called At House. Our Rinnai was six years old and we kept getting the error 10 message and we would get cold water. Makito (I hope I got the name right) came by and diagnosed the problem. Since our warranty was over, we decided ( no pressure from him) to get a new water heater. He had to order it but he was back in two days and had it installed in about 3 hours. They even registered the water heater with Rinnai for us! Talk about great service! Thank you At House! read more

Reasonably priced, installation took just as long as they estimated without a hitch. Instructions on operation and maintenance provided. They even threw in a couple of bags of salt for the water softener. It was my first experience having anything like that installed, and will definitely use them for any future projects within their scope. read more

I HIGHLY recommend them! They are competent, responsive, and responsible. Their meticulously detailed and careful work was impressive. Exceptional work ethic. Thank you At House. We are happy customers and will definitely recommend your services to family and friends (and YELP)!! read more

I contacted At House on Friday for information on tankless hot water heater. Kevin returned my call within an hour and explained with details what my options were. We were able to schedule for an in home review/estimate for the next Monday. Hiro came on Monday before the appointment time (very seldom occur with my experience). He was equally patient and detail oriented with every facet of the transaction. Gave me a very reasonable quote and was able to schedule installation the next day. Again his technician came before appointment time the next day. Finished the job, cleaned the work area, explained everything needed. Got my receipt and everything I needed for rebates the very next day too. Can't be happier with the whole experience. read more

Hiro and his team are honest hard working individuals and their end product shows for it. We are beyond happy w/ their service from start to finish and can't recommend them enough. Made the whole process seamless. If no one can, Hiro can! read more

Professional, timely & fair pricing. They know "tankless" hot water heaters. I talked with several and all wanted to send someone out to look at my needs. When I told them my problem, AT House gave me a quick estimate to fix. When I told them the age of my current system, we engaged in a good discussion about the expected life of a system. It's been a long time since I've experienced a professional approach with great customer input and care. I highly recommend. read more

wow, what a great team. I was really impressed with the professionalism and dedication this guys take their job. I will definitely will use them again. in fact, I put their number as "The plumber" in my contracts. great job! read more

My 10 year old tankless needed to be dusted (internally). Hot water was starting to cut out when a couple of people were using 2 showers at a time. Kevin came out and it is working great again. Good company for repairs, prompt, polite, and they get the job done. read more

They installed a filter on my tankless water heater and did an excellent job! They gave me the best price to do the job and will be coming back and maintaining it for me when. I highly recommend them!! read more

We have been using at-house for several years - they are the Gold standard in service and product. Kevin is wonderful and explains everything fully. There has never been a misstep and with 53 tenants at this building it's important to keep them happy with their hot water needs. A great business! read more

Hiro and team installed a tankless water heater and a whole house filter for us. Hiro is knowledgeable, was patient with my questions, and really listened to what we wanted out of each product. We were considering a whole house filter with salt, but changed our minds because my husband has high blood pressure. Hiro didn't miss a beat and was able to find the model we wanted. Out of the six plumbing companies I spoke with, his was the only one that provided an itemized invoice. He also recognized that our previous whole house filter had poorly routed piping, and fixed it. Straightforward, easy to work with, and clean work. It was a great experience. read more

Well, that was easy. I called this morning and they were by before noon. I have Noritz tankless water heater and we have been getting intermittent shutdowns with an error code 90. It rarely happened to me but often happened to my wife right as she was rinsing out the conditioner. It sucks to rinse off in cold water. And it's embarrassing to tell house guests to let us know when the goes cold so we can reset it. I delayed thinking that I was going to be able to fix it, and hoping the cleanup of the igniter I did may possibly make a difference -- it did not. Anyway, he spent about an hour and cleaned everything out and adjusted the manifold gas pressure which was quite a bit off on the low end and he mentioned could have been a contributor to the error code 90 shutdowns. Now we are back to hot water without fear. (Note: My original installer was probably the cause of the poor adjustments. This would make the fourth thing he failed us on.) read more

Excellent, prompt, honest service! The pilot light on my water heater kept going off. Chris came out, identified the problem part, and told me he did not have the proper replacement part because my heater is so old. A lesser company would have tried to sell me a new water heater then and there. Instead, Chris got curious, took apart the malfunctioning piece, determined the part was gunked up, and worked carefully to unclog it. Then, he put the part back together with a new feeder line and reinstalled it into my water heater. Voila! My heater is working again...and the pilot light no longer goes off. Chris let me know I was lucky he was able to fix the part. Indeed! I feel VERY lucky I called At House. This evening, the owner of At House called to ask if I found the service his company provided satisfactory. I told him more than satisfactory...Excellent! read more

After researching the performance specifications and customer ratings of several tankless water heaters on-line and asking my plumber about them, it became obvious to me that tankless water heaters are a very specialized field. I narrowed my choice to Japanese manufacturers and after reviewing installers with factory training, I called At House, Inc. Later that same day (Thursday), Mr. Hiro provided a comprehensive on-site inspection of the existing gas line and vent infrastructure together with my requirements, and he recommended a Noritz EZTR50 unit. Installation was scheduled two business days later and by noon the following Monday, the installation was complete. I was very impressed with the professionalism, punctuality and competence of the At House, Inc. technicians that performed the installation and my family are very pleased with the performance of the unit installed. I highly recommend At House, Inc. enthusiastically and without reservation. read more

Hiro was great! Arrived on time. Diagnosed and fixed the problem - bad igniter. Cleaned up the unit and surrounding area. We had hot water again 30 minutes. Thanks! read more

My wife and I feel so fortunate to have finally found At House and Hiro. This company is all about great service and value. We designed our house with radiant heating 15 years ago(still not prevalent in SoCal) and the mechanical engineer specified a boiler, HTP Munchkin, that provided hot water for both heating and domestic use. The Munchkin, a fairly new product back then, had design flaws and has been out of production for a few years now. Every time it had an issue we'd lose both heating and hot water, which sucked in the winter, so we finally decided to replace it. We took our time researching and At House was the most helpful and patient company in leading to our decision to replace the original boiler with a Rennai tankless water heater for domestic and a Navien boiler for heating. In addition we added a water softening system. The total price came out to be half of what some of the companies wanted for just putting in another boiler! The work was done with such high efficiency, workmanship and cleanliness we're still in a bit of disbelief. I'm writing this review not only to show our appreciation for Hiro and At House for the great work but to also warn everyone out there - especially if you also have radiant heating like us - to watch out for companies that want to take advantage of the situation. When we first started looking for a company to help us we were recommended a plumbing contractor/mechanical engineer that specialized in custom homes in the Newport area and claimed to be the expert in radiant heating. They charged us $500(including drive time) just to come diagnose our original boiler then wanted up to $9,000 to fix it or $16,000 to replace it with another boiler from the same manufacturer! They refused to break down the cost and pretty much said "good luck" on the phone when we questioned the price. Another company came for free then gave us a quote for $15,000 to install the Navien boiler that we ended up getting with At House. Like I mentioned, At House got us everything plus water softening system for around half the price - material and labor. We'd recommend At House and Hiro to everyone. read more

Taking showers was a nightmare with my tankless water heater. Hot water would only last for 3 minutes then turn cold. With 2 teenagers that I had to remind to take showers, this only gave cause for them to slack even more. I couldn't blame them, we were miserable. I'd run late in the mornings waiting for the water to turn hot again, upwards for 7 minutes. I had a popular plumbing company I found on Yelp and used them for 6 years. They never completely solved the problem. What they charged me each year for a reoccurring problem lead me to look elsewhere. So I called At House based on their reviews and received a decent quote. Kevin with At House came out to our home in April of this year and solved our nightmare hot water issue. Although he came later than the original appointment time, he called beforehand and explained it was due to an internal issue. Upon arrival he got straight to work. Kevin explained what he was doing while he worked. He talked about what the different mechanisms do to provide the hot water. He also told us what the proper color of the flame should be and what to look for. Once he took out our burner Kevin showed us how filthy it was which told us the other popular plumbing company had never cleaned it properly. Now 6 months later and hot water continues to flow normally which is why I waited to write this well derserved review. I had to be sure. I have found a plumber I trust(so far) and I hope to have a long business relationship with At House. read more
