We wanted to replace our old water heater with an energy efficient solution and First Class Water Heater delivered and replaced it with a heat pump driven water heater. The guys put some new pipes in because the water heater needed to move to the opposite of the room in order to fit in perfectly. The complete job was done in half a day. They left the place tidy. The new water heater is working flawlessly and in combination with solar helps us saving money any single day. First Class Water Heaters charged us a very reasonable price, about the half of the price another local company could offer. They even helped us with saving $800 from a California Incentive program. Very satisfied with First Class Water Heaters! read more

My water heater was leaking internally and water was trickling out from the top and down the sides. Francisco came and replaced my water heater on the same day! He was very knowledegable and skilled about the work. He was fast, clean, and was good! Very professional and explained what he was going to do and what some of the parts actually do and how they work. I would definitely go him again anyday! Kurt from the office was also very professional and communicated well about the job at hand and what the next steps were each time I spoke to him. read more

We saved $1000s by using David and he is very knowledgeable and personable. He responded immediately on a Sunday. It would have cost $1900 for an installed 50 gallon tank water heater compared to $3200 at another company. We always wanted a point of source water heater to save on the gas bill and took his bid of $3900. A bonus is I was helping an individual with a family instead of my money going into the corporate pot. PS this is not a plumbing company so any reviews for water leaks are for a different company. Water heaters!! read more

Don't use this company! They replaced my regular water heater with a power vent without giving me the options. What's worse is that they installed a power vent water heater in June of 2022 that was manufactured in 2016. So the warranty on this unit expired only six months after it's installed in my house. To make the matter worse, they charge me over $1000 to modify my house to accommodate this power vent Water heater. After only 3 1/2 years having this old water heater, I have to spend another $785 to get a new one installed and won't modifications needed because it wasn't done correctly last time. I have reported them to FTC today because they don't return my calls. read more

First Class Water came out in October 2024 because my dining room ceiling was showing signs of a water leak. the technician came out and determined that it was my bathtub faucet which was loose that was causing the problem. I asked the technician to cut and check the ceiling and he said he preferred not to. I trusted that he knew what he was talking about. However, he did not. When another company went to cut the damage ceiling they noticed the wall was still wet and was able to see the pipe was leaking. In fact, the bathroom plumbing wasn't even in this section. Had the First Class Water technician did a thorough job, he would have been able to properly diagnose the issue and it wouldn't have cost me additional money to fix what they should have. read more

FCWH provided great service via Eli Santos. Eli was courteous, knowledgeable, and overall solid service agent. He helped diagnosis the issues with our tankless water heater and educated us in the process. By the end of his visit I was sold on First Class Water Heaters and especially, Eli. I'd definitely recommend this company for your water heater needs. read more

I'm giving them two stars only because the work they did was done well. I'm sure they would be fine if you hired them to come out and replace your water heater for you, but they were assigned to us from our home warranty provider. I paid my deductible to the home warranty provider and they sent out First Class Water Heaters for the replacement. When the work was all done, the technician told my wife there would be an additional $100 charge, even though he had no invoice or receipt showing any extra charge. He told her that we would receive an email the following day with the invoice. Total BS..!! To avoid confrontation, and not knowing that I already paid the deductible for the replacement, my wife wrote a check to him for $100, then he left. She immediately called me and let me know about it. I made a few calls, one to their company, one to my home warranty provider, and one to my bank to place a stop payment on the check! Very shady tactics! Be careful, there's scammers at every turn! read more

If I could leave ZERO stars I would. Came to fix the tub faucet and replaced it with a very cheap version that broke within 3 weeks. Currently unable to even take a shower. When the technician Sergio came, he immediately became upset because we asked him to wear shoe covers (we have a crawling infant) and to speak in a low voice because we'd just gotten the baby to sleep. He continued to speak loudly and slammed the baby gate shut on his way into the house. After looking at the issue, he came back and said he didn't have any parts to fix it and we'd need to wait again for another person to come back. Again, we asked him to speak in a lower voice and he then told us someone would be back out and to make sure we scheduled it during a time when our baby wasn't sleeping. He then walked out, flung the door open and stormed out. WTF! read more

amazing and prompt service I feel horrible I didn't catch the name of the technician who provided my service. but he was amazing I made my request w. my home warranty on a Friday afternoon. I called first class water heaters within 15 minutes & they had a record of my request. no one was available to service me over the weekend but they had a technician out Monday afternoon. he came inspected and made incredible recommendations including providing education regarding how to prevent future issues. I missed their return call on Tuesday to complete the service. I called back Wednesday and staff returned Thursday morning . my claim was completed in less than a week and over a few business days. the technician was African American and an Oakland native. being service by someone local was also a very good experience. read more

"I was so impressed with the quick response for my broken water heater! Francisco came the day after the call was put in. He diagnosed a leaking water heater and notified my home warranty company promptly. The parts were ordered right away and the water heater was installed in no time! This whole job started on Thursday afternoon and my water heater was installed on The following Tuesday!". read more

The technician, Harrison, did not diagnose the problem with my kitchen faucet, and made a report to my insurance company that did not represent the circumstances accurately. As a result, the claim was denied for extremely unfair reasons. On another occasion, he told me the leak in my shower could only be fixed by removing the tile and cutting a hole in the wall. A second plumber was shocked at that diagnosis and was able to easily repair the problem without disturbing the tile. I would not trust this individual to perform the services of a reputable licensed plumbing contractor. read more

Poor customer service We were assigned this vendor through our home warranty. It took a long time to have them out for the water heater--they were assigned on 1/12 and finally came out on 1/18. We were told we needed a new water heater. Since we needed a new tank, wanted to look into upgraded options such as a larger tank or a tankless system. I called First Class and was told the rep would call me back with pricing options. No one called. I called First Class 2x and even left a message, and when I finally connected with the staff, again they said the rep would call me. Eventually he did but he was not sure if our Home Warranty would allow us to upgrade. He said First Class would call me later that day and tell me what the options were and that if we went with a bigger tank, he could install it on Monday. No one called. I called again during business hours but only got a voicemail and again no one called me back. It's now Monday and I called first thing. When I explained the urgency and frustration that I had yet to receive a call back among the many times I was told I would receive a call or in response to my voicemails, the staff defended the situation stating the rep had eventually called, denying that they'd ever not called me back. For frame of reference, we have young children and we we don't have hot water, can't shower, run our dishwasher, or washer/dryer. We've been bouncing around to friends houses to do these things for over a week now. In total, it will be 13 days without hot water. There's been no urgency from First Class, no customer service, and this is why I do not recommend this vendor read more

To make a long story short, American Home Shield dispatched this company to our home since the first company they dispatched had came and said that they did not work on power heaters and that the problem with our heater was electrical. Lo and behold, Pedro from First Class Water Heaters came and evaluated that that was not the case. Instead of giving us the run around, he stepped up and fixed the issue with another colleague. Thus ending our third fourth day without hot water in the freezing temperatures of NorCal this week! I am so grateful and impressed by the determination of this company and their technicians to get things done quickly and correctly. Pedro was professional, clear and transparent with what was going on and what he was going to do to solve it. He even does a phone follow-up to make sure everything is working up to order and to guide you if anything needs to be adjusted. It really goes to show that if you make the right first call, you can avoid a lot of trouble and frustration. Thank you, First Class Water Heaters! read more

We went through 4 different companies before deciding to have our water heater upgrade work done by David at First Class Water Heaters. The work was carried out quickly and smoothly. When we later had some unrelated issues, they came back during the weekend without complaint or additional fees and it was a great experience overall. We will definitely be return customers. read more

5 Star Review. First Class Water Heaters was the company assigned to me through my Home Warranty. Jayme and John were the technicians that showed up. They quickly assessed my water heater and worked with my home warranty company to see what was covered. They were incredibly friendly, professional and timely. From start to finish they replaced my entire water heater system in an hour or so. They made this process super easy and stress free. I would recommend them again! read more

We had our water heater replaced and our pressure release valve and Jaimie was a true professional and did the work efficiently. I am so happy. I would highly recommend this company. Thank you! read more

We submitted a claim through our home owners insurance to get a leak fixed. The tech, Charles, who came out to look at it didn't even ask where the leak was and told us he would order this certain type of piping for the house. And suggested we just repipe our entire house instead of repairing the leak which he quoted would be around $3,000-$10,000. A week goes by, mind you WE CANT USE OUR WATER AT ALL in our house and we were patiently waiting on them to fix the leak. Then we find out from our home owners insurance that Charles canceled our claim and we had to start over with a new company. He never returned my messages and canceled our claim. A different plumbing company came out and found the leak, turns out the type of piping Charles claimed he ordered isn't even what we have in our house. After thinking it over, we realized he didn't even look at our pipes!! What a waste of time. These people will scam you. read more

I filed a review earlier because I felt I was getting the run around , But I found out the owner was out of town . He called me when he got back and said he will be out Thursdsy the 6th . He was here at the time he said he would be and he was very pleasant then started the work to correct the problem. It only took him about 20 minutes . I am grateful for his service. read more

Thank you Dave! A combat veteran was in dire need of a water heater. It had started to leak and they did not realize it till the next morning not knowing they had no hot water. They called First Class and Dave was out there that morning. He accessed the situation and told them their 16yr old water heater needs to be replaced. He gave them a great price with a veteran discount and had a new one installed same day. I want to thank Dave and everyone from First Class Waters for their help and getting my fellow veteran with hot water again! HOOAH! read more

Our water heater went out and this is the company the home warranty called and recommended. We received 5 start service the technician Charles was on time and very knowledgeable about the work he was doing. Would highly recommend this company for all my water heater needs. read more

I opened the door and Tre' the technician, full of life with outstretched hand cordially and professionally introduces himself and the initial meet & greet was only the beginning of an exceptional service experience. The hot water tank was diagnosed, parts to be ordered and timeline for receipt and follow up for final repairs outlined clearly that subsequently led to repairs and "HOT WATER"....HALLELUJAH!! Tre' was extremely patient, kind and understanding in receiving and responding to my questions and meeting my service satisfaction. Highly recommend FIRST CLASS WATER HEATERS...and it's my sincere hope that Tre' is your technician. Great job! And thank you Tre'!! read more

Carlos Gomez replaced our tankless water heater this week. We could not have asked for better service! His expertise and knowledge of the system was impressive. Carlos was friendly, professional and attentive to our needs. We knew we were getting quality work. Not only did he replace our water heater, Carlos also took the time to review the system's capabilities and maintenance requirements with us. We had a really bad experience with another company prior to getting in contact with First Class Water Heaters and the difference was immense. We will recommend this company every chance we get. read more

Thank you to Jayme and his son John for helping replace and install a new Bradford-White water heater. Our water heater broke completely and needed replacing First Class Water Heaters provided a timely response and replacement. They worked through my American Home Shield insurance and everything was a breeze. Jayme and John came in and installed the new water heater. Both were professional, kind and was a joy to work with. I recommend them highly. read more

I'm going to give 5 stars for the tech who replaced our water heater. He was on time, professional, and efficient. Great work. The one star goes to the back-office staff, specifically Andrea. Home warranty requires the homeowner to provide the repair company with a $75 check, which I gave to the tech. I have been traced multiple times by Home Warranty for lack of payment, which is the responsibility of First Class Water Heaters, since they collected the deductible payment. When I talked to Andrea, she decided to give me a banking 101 class on how the check process works, really? She then asked for a check number - who writes that down these days? She threw the responsibility to me and took no accountability for possibly misplacing the check. Even if the check wasn't cashed, I now have a check floating around with my bank account number exposed. I will not be submitting another check and will request Home Warranty to collect directly from them. Great tech service, horrible back-office support. read more

Manage a commercial residential community and originally took bids for replacement of commercial capacity water heaters. First Class Water Heaters was selected. First based on responsive of the Owner, Dave Ballard. Dave is very professional and attentive. Replacement of the two water heaters were installed very efficiently and simultaneously by two individual technicians within a couple of hours. Making the expected service time most pleasing for the community of residents whereby these water heaters service. Water interruption was at its minimum. Working in commercial management for many years. I have not experienced such a seamless transition for a replacement of units so efficiently. Separate--a few other plumbing repairs came up unexpected in individual units. Dave rolled-in his technicians without hesitation and without delay upon my contact. Even an unknown underground water leak of our potable water line. Again with the greatest of ease and efficient response and repair they came through. Definitely recommend and support First Class Water Heaters for your residential and commercial repairs and new installations. Found them at just the perfect timing. For sure a positive addition to my goto contractors for managing my commercial business. Thank you First Class! read more

Great experience with first class water heaters today. Eli-Luis was/were excellent. They were fast and efficient with fixing my leaking kitchen pipes. This is probably the best company AHS has on the roster for plumbers and I will be requesting them if I ever need a plumber in the future. The office customer service was excellent as well - they contacted me to find out if I wanted an earlier appointment and were very accommodating. Highly recommend! read more

On a Monday, my 15YO water heater gave up the ghost and I was without hot water. My home warranty company called upon First Class Water Heater to evaluate the issue. That same day, I received a scheduling call from Monique, indicating Pedro would be there at 10am the next day (Tuesday) and would call me 20 minutes before he arrived. On Tuesday, Pedro called me just before 10am and showed up as promised. He and Charles quickly determined the problem and told me that when they left, they would contact my home warranty company to request authorization to replace the unit. They managed to get my old unit fired up and I was able to shower before it conked out. By 3pm Tuesday, my home warranty company had called me to confirm that I would be able to take care of paying for the items that were not covered by the warranty. I requested a cost breakdown from First Class, and Monique emailed it to me. I authorized the home warranty company for the non-covered costs, and by 4pm Monique had scheduled the guys back out for Wednesday. FAST! On Wednesday, the guys gave me a 20 minute heads up phone call on their way to me, and arrived as promised about 2pm. They drained the old unit and reinstalled a brand new unit, bringing it up to code with an expansion tank and gas line drop. NOTE- the draining of the old unit was the longest part of the installation. Why? Because whoever owned the house before me did not drain it each year as recommended. You should have seen how much sediment came out of the old unit. And the sediment kept blocking the drainline. So people, DRAIN YOUR WATER HEATER ANNUALLY! Lol. When Charles went to connect the overflow piping to the existing copper pipe under my house, the riser came off in his hand. Apparently the original installers never soldered the joint! Now, the crawlspace under my house is tight, muddy, and probably filled with bugs and spiders. Charles didn't even bat an eye and crawled under with his torch and flux to solder the joint. The guys were done by 5. Again most of the time was spent trying to drain the unit. Once it was drained and removed, the actual install took about an hour (including Charles' adventure under the house). The guys were courteous and professional, taking time to explain things to me as they went and answer my questions (and I ask a lot of questions.) I would highly recommend them within the scope of water heater issue diagnosis/ replacement. I attached a shot of the newly installed unit. Thanks guys! read more

We had a GREAT experience with Eli from First Class Water Heaters. We recently purchased a home and our water heater stopped working shortly after closing. We first had another company come who came for 5 minutes and told us there's no way the unit could have been functioning when we bought it (even though we had been using the hot water...) and that it needed to be fully replaced. We then had First Class Water Heaters come out - Eli did a thorough investigation, and within a short amount of time he was able to identify the issue and got the water heater working again!! We are thrilled, and if/when we need our water heater fixed again or replaced they will be the first company we call. read more

Jayme Perez from First Class Water Heaters was professional, respectful, efficient, and transparent. I would definitely recommend him to anyone needing service work.

Again, great work and would absolutely recommend Jayme! Thanks! read more

Jayme Perez was our technician. He came out and replaced a few things on my water heater. He was on time, professional, personable, respectful and very transparent. He knew what he was doing and had all the right materials to get the job done. It was obvious he took pride in his work. He was in and out in less than an house and was very efficient! I would recommend him to anyone who's needing service work! Thank you so much Jayme! You truly set the bar! read more

They did a wrong inspection of our water heater which caused our insurance company deny the coverage. We told them multiple times about it but they just denied to do it properly. Then another company came and inspect wd it correctly and insurance company covered it. Because of their wrong inspection, it would have caused us 3000$ or more. read more

Was connected to this company via my home warranty contract. They were able to come out quickly and when Carlos arrived, he assessed the issue and came out the next day to complete all repairs & replacement. He was nice, knowledgeable, thorough and efficient! A+ highly recommend!! read more

My friend just bought a new home in Tracy and already the boiler broke and leaked within the first month. Also the Kohler brand toilet seals is broken causing the tank to refill every 20 minutes. Replacing the seal is difficult with this brand and so in general the warrantee company would just replace it with a cheap toilet. The warrantee company sent out Carlos from the First Class Water Heaters. Carlos was great! He was a honest man. He saw that our toilet was Kohler to be replaced by a cheap toilet from Home Depot and told me about it. He did not just install it and go. He offered us an option to upgrade the toilet by adding more money to cover what the warrantee payout. In this case, we added $109 more and got another Kohler toilet. Carlos was workmanship was very good. He left the place clean. Both the boiler and toilet was done in 3 hours. I am really happy about this and would recommend the First Class Water Heaters.. Ask for Carlos. read more

Poor customer service. Work went beyond promised deadlines. Showed up late. Over charges. Sloppy work.

First Class Water Heaters is truly First Class! Fidelity, our home warranty company assigned First Class to our claim. They contacted us the that night; however, they had to wait until morning for a claim number from Fidelity. I called First Class the next morning at 8:00 am. Their serviceman, Jamie, was in our area and arrived at our home within 30 minutes! Jamie was great; he was professional, friendly, and efficient. Problem solved quickly and hot water restored within 30 minutes. Nobody likes to have problems requiring a service call, but if you are in the East Bay and have a problem with your water heater, call First Class Water Heaters! read more
