Prompt and very competetive. Had a 50Gal Gas Water Heater went out at my rental property. Out of the 5 bids from Yelp, Water Heater Warehouse came in with best price which includes a $100 discount for return customer as I've used their services previously. Maria was very helpful in set up the quote and scheduled Arturo to perform the replacement within the SAME day. Arturo showed up on time and completed the work within one hour much to my tenant's delight. The process and payment were very professionally handled. Much appreciated and would not hesitate to recommend Water Heater Warehouse to others. read more

Awesome experience with water heater warehouse! We discovered our water heater needed to be replaced on a very cold morning this past December. Initially I was worried my family would be without hot water for days, but then I remembered Water Heater Warehouse. I knew if I called them, I would have a new water heater that same day and they did not disappoint. Great customer service from my initial call to the office, all the way to installation, payment, & follow up. And bonus, I know I'm supporting a family-owned company that's in my community/neighborhood, which should always be the way to go when possible. read more

Went through SoCalGas to purchase a new tankless water heater & added installation. We were happy that Water Heater Warehouse (WHW) contacted us ASAP to schedule the install but they couldn't install until 6 days out: Two days before, we panicked thinking we might need a permit. Called to ask if we needed a permit for the new tankless water heater & spoke to Joey & he sounded unsure & said we don't need a permit because our install wouldn't have been scheduled if we needed one. Didn't give me the warm fuzzies so I googled & per our city's website, Yes, a permit & inspection are needed. We called the city & they were super helpful & reassured us that we can have the tankless water heater installed first & schedule the inspection later. So we called back & told Joey that yes, we need to get a permit & if they will be submitting the permit with their contractor number. He said yes. Hopefully he knows to check first instead of guessing & give customers the wrong info. We were happy with the removal of the old gas water heater & install of the new gas tankless water heater by Chris & his apprentice. Both super nice. After the install, the tankless water heater took forever for the hot water to come on for showers upstairs, even when I turn on the recirculator on the app. So annoying & feel like we're wasting so much water. We agreed for Chris to have it set to smart schedule where it will monitor our hot water usage for a week to develop a good schedule. 5 days later, we smell gas by the newly installed tankless water heater. Called WHW & Joey said to call the gas company. Gas company came out 4 hrs later & confirm that there indeed gas leak & he had to shut down the gas & tankless water heater. And told us to call the installer to come fix the leak. Just called WHW but of course they are closed & left a message with customer service. We thought it would go smoothly as they have great reviews but at this point, we would NOT recommend this company. Not sure if it's a faulty unit or faulty install. I'll update my review when we find out. We didn't pick this company. It was through purchasing the tankless water heater from SoCalGas. It's been a week & I still feel like I'm wasting water just waiting for the hot water to come on. read more

Water Heater Warehouse - Rinnai 11.2 gas tankless water heater installed to replace old water tank heater - Water Heater Installation/Repair Near Me - Fullerton, California

Water Heater Warehouse installed my tankless water heater approximately one year ago via a promotion with SOCal Gas. They did an excellent job at what I think is a fair price. One year later the recommendation is to descale the tankless heater annually. I had Water Heater Warehouse do the project for me. They were on time, took a bit over an hour and the crew they sent was courteous and efficient. Highly recommended! read more

I called customer rep to ask for scheduling an assessment and I was told it's free due to a recent thermoset replacement only one and half months ago. Then they send a technician come over and check why the water heater tank doesn't work again, after 30min open everything and close up, he said there's nothing wrong, everything looks fine, then he left my house. After, he left my house, it seems the water heater get back to normal. And then the customer rep call me for a $89 assessment fee(I just paid $190 one and half months ago). What I suspicious about is there's something weird after the first replacement of thermostat that only support the water heater tank back to normal for a little bit more of one month? And I have to pay extra $89 for let it back to work? So what about next months, I will see you guys again? read more

I had a great experience with Water Heater Warehouse. First rate customer service from office staff and from the technicians. The technicians arrived on time and did an excellent job installing my tankless water heater. I couldn't be happier with the overall experience! read more

I got several quotes to replace my 30-year-old water heater, and Water Heater Warehouse was by far the most affordable. I couldn't believe it at first, so I asked multiple times if their price included all the labor and code updates (new valves, flex lines, straps, drain pan, etc.). They assured me it did and it really did! They were able to schedule me for a same-day appointment on a Saturday, which was amazing. Eddie and his assistant showed up on time, were professional, and got everything replaced quickly and cleanly. The new tank looks great, and the total was exactly what they quoted - no hidden fees or surprises. read more

I havent even gotten a chance to book my installation. So far took them longer than 3 days to call me about the product. Then Maria on the first day of acknowledging the order calls me at 651p. I call back and couldnt get her. I got an answering service mentioning i can make an appointment online, thats a lie. Second tike i call during regular business hours maria is out for the day because there is only one person booking appointments. Please be aware of this company and their non upto date technology. Its 2026 maria could have sent an email. Your company is not meeting the actual needs of the customer. I think that should change maria needs to do more work and utilize email. Other companies due while meeting the demand of their customers. read more

I had an outstanding experience with Water Heater Warehouse! From start to finish, their team was professional, responsive, and detail-oriented. Veronica in Sales was fantastic--she kept me informed every step of the way, answered all my questions promptly, and made the entire process seamless. Their estimate for the project was also the most reasonable compared to the other quotes I received. The installation team, Eddie and James, did an exceptional job installing my Bradford White water heater and Grundfos Alpha Recirculating System. Their workmanship was top-notch, and they made sure everything was installed to code and working perfectly before leaving. Highly recommend them for anyone looking for a reliable, professional, and honest water heater installation team! read more

My interactions with water heater warehouse was ok, then disappointing and then ended good. I connected with them as they were the fulfillment company when buying a tankless water heater through the SoCal gas marketplace. After two technician visits we had lots of phone calls back and forth with main office to keep rescheduling due to miscommunication on the clearance needed in garage since our garage was full of storage. Fast forward a month and I conceded to go replace back with a traditional tank so we wouldn't have to change any ducting in garage. My appointment on day of install pushed from 10-12noon, then 1-3, then 4-6 to are you sure you can't wait until tomorrow? Super frustrating for my tenant who waited all day for the install. However as bad as that comms was, we get that crews get caught up and stuff happens. Just sucks when you're on receiving end. Their office person named Sabrina called and made it right. She offered a discount for the inconvenience and bought my tenant dinner. That's customer service done right after an unavoidable inconvenience. I say that with the clean install and that gesture I'd recommend them to others because they did the right thing as a business. Could have easily gone down a one star/bad path but didn't. Way to go Sabrina! read more

After installing a new water heater we still had an issue with hot water getting to the kitchen sink often waiting several minutes for hot water. We requested a service call to check it out and had an appointment for 2 business days later. The service team arrived on time and determined that a circulation pump would solve the problem. The office sent a very reasonable quote right away and we were able to get installation that day and was efficient. read more

If you are in need of a tankless water heater, you need to go to so cal gas marketplace then order one from there. Water heater warehouse is the installer contracted through them, and they are fantastic. From ordering to setting up an appointment to installation took less than a week. Other plumbers were asking 7500 for install due to older pipes and location, but not Water Heater Warehouse. They encountered an issue while installing, but did not charge extra. What I initially paid is what they charged. (A flat installation fee. Since the order was through so cal gas market place the rebate was taken off the total and I did not have to submit a physical rebate potentially having issues later. ) Danny and the other installer did a great job. The heater is now in a clean area with shinny new copper pipes. read more

Gas leak after installing the tankless water heater. Tried to contact them but couldn't get a response 2 hours. Ended up calling SoCal Gas emergency hot line and they sent a technician to fix the leak. He said we did the right thing by leaving the garage door open and called them. The garage could explode if we left the door closed and leave it for a prolonged period of time. read more

My water heater was leaking. They came out the next day on time. They did not have a 50 gallon heater on the truck (I did not confirm w/them that I needed that size when I called). They said no problem. One tech stayed behind and prepared and readied the parts needed to install while the other drove to get the new heater. When the new heater arrived they took out the old one installed the new with all new water lines & new valve, gas line & valve and earthquake straps. 2 hours from start to finish! Friendly techs and did an excellent job! Highly recommend! read more

I saved the water heater warehouse because i had them flush my tankless water heater every year and they sent me email reminder. i recently called the office to book the tankless heater flushing for rate of $175 which is fine. the team of Sergio and another tech came by and they tried to come inside my home with their outside shoes on and i asked them politely to have foot booties. they told me they don't carry any booties and they told me wait until they go to their office to get them and come back... i'm like what...? i'm not waiting for them to bring back booties for another 1 hour so i just said it's fine and asked them while they were at my home, i had a concern on 2 bathroom showers temperature getting cold while using hot shower. Sergio mentioned it could be the check valve that went bad and need replacement, and the office will call me regarding the quote for the services. after they were done and a day passed by, i did not hear anything from the office. i waited until Tuesday and called the office to inquire about my concern and the lady spoke on the phone gave me a quote for 1 bathroom only. i asked the lady on the phone that i inquired about 2 showers and she said the techs only noted 1 bathroom. i said thats fine, i asked for the total quote again and asked her to give a follow up call regarding the quote. she told me she will check with the techs and get back to me. it's been 4 days and i have not received any message, email, or phone calls regarding my concerns... twice in a row. if i call the office to ask for my quote again, i know i have to explain everything over again and i don't want to waste my time and waste Water heater warehouse's time. if the business don't want your business, i have no problem with it. at least don't waste my time back and forth while i could have contact different services to get the quote sooner. i am no longer this company's customer and i have found better, smaller family company who cares about any customer regardless of the size of the services or job. if you are the owner of Water heater warehouse, please have a nice team meeting with the phone reps and technicians together so you guys are on the same page, so you don't waste customers time. read more

Very satisfied with the quick over the phone quote, yelp discount, and quick replacement of our water heater with a new unit by the same manufacturer we previously had, that's only available through a plumber and not through a DIY store. Friendly staff and field tech. Explained everything well and did a neat/clean and thorough installation. Also showed me how to look up the new (and old) water heater on the manufacturer's website for warranty info, etc. read more

They came the same day I called. Arrived right on time and got right to work. Super friendly and fixed things right up! 5 Stars!

After searching around for someone to replaced my water heater, I decided on WHW. I received many quotes from several people. I was looking for a good balance between price, warranty and service. WHW provided all 3. The pricing is competitive and the customer service was top notch. The receptionist, Sabrina answered all the questions I had prior to booking the service. She provided transparent pricing and went above and beyond to make sure I know what product and service I am paying for. She reassured me that there will be no hidden fees or added cost since the price already includes labor, fittings, hot and cold flex lines, gas valve, gas line, gas sediment trap, earthquake straps, drip pan and haul away/disposal of old water heater. Everything will be done up to code. They have the best warranty in labor and parts compared to other quotes I received as well. After scheduling with WHW, Arturo and Chris came out to install the water heater. They arrived within the allocated time slot - friendly and professional. They were happy to let me watch them work, answered all the questions and educated me on how my new water heater works, where are the shut off valves during emergency, how to check my pilot lights, how to adjust my water temperature and check my status light for trouble shootings in the future. Chris and Arturo hauled away my old water heater and left my garage clean. I highly recommend Water Heater Warehouse! read more

I had them replaced my water heater 3 years ago, September 14-15? Of 2022 around 11:30am. Look I'm just a simple girl, trusting you to do your job and not screw me over. We are already living in a messed up world where you get screwed already but why do I need to pay you to screw me??? At least let me know before it happens. I clearly do not understand the world of plumbing and water heater, i paid experts to do their job correctly. I only know they screwed me over because my plumber friend told me all the things they did wrong. And it sucks because like what can I do now? Life is hard already can we screw the aholes, instead of people that are willing to trust you? read more

Our 25 year old water heater started leaking and we knew we needed a new one. I got a few quotes and while Water Heater Warehouse wasn't the least expensive, they seemed to be the most reputable and honest. I appreciated they could give me a quote over the phone and answered the phone promptly when I called back with a few questions. They gave a same day 2 hour window for install, which went very smoothly, and they left the area the leaking water heater was cleaner than they found it. Would definitely recommend. read more

I need a new water heater due to the old one was leaking. I'm looking plumber with Bradford White License since after research this is the BEST BRAND for water heater. I found Water Heater Warehouse with great reviews on yelp. I called for quote and the rep said need to speak with technician. Surprisingly Chris the owner called himself. That is totally a plus if the owner spend time to talk with customer and answering all questions. The appt set up for Sat, originally between 1-3 but got an email a day before it changed to 2-4. Danny and Hugo arrived on time exactly @2P, very knowledgeable and friendly technicians. I told them that I spoke with Chris will add the Corro Protect Anode Rod. They said this the first time to install it. I was nervous but finally they can figure it out and installed it great. I'm so happy with the service and price! Its has been 5 days and hope not having problem in the future. TOTALLY RECOMMEND IT 100% !! THANK YOU CHRIS, DANNY AND HUGO ! read more

Water heater warehouse was recommended to me by a friend who was very satisfied with the water heater installation at his home. Therefore, I had them install a new water heater at my home and I was quite satisfied with the product, service, and price. One note. As far as the insulating foam that they install around the water pipes I would insist that they add zip ties as the adhesive on the foam doesn't last that long. read more
